When the family is driving to the lake, an instrumental of My Wettest Friend can be heard.
This is the 14th episode that Isabella doesn't appear; also the 2nd 2-part episode overall.
This is the second time Phineas and Ferb were seen in their swimsuits since "Lawn Gnome Beach Party of Terror". However, from this episode on, Ferb now wears dark purple swim trunks with light purple lining.
The pond at the bottom of Phineas and Ferb's lab connected to the lake functions identically to a moon pool system, an element frequently deployed in underwater habitats such as Nosey's.
The word quadrant losing meaning to Doofenshmirtz when he repeats it many times over a short course of time is a real psychological phenomenon called semantic satiation.
First time where Ginger does have a speaking line.
When Candace says "[I'm an animal and I] bite my own hiney", it may be a reference to "S'Winter" when Perry escapes from the chocolate casing by "eating his own hiney".
Phineas and Ferb first mistake Isabella's, "Hi, Phineas," for something Perry had said, and then the bird's, "I sure love worms!" for something Isabella had said. In "Get That Bigfoot Outa My Face!", Candace thinks a squirrel is talking to her, only to find that it is her grandmother's voice.
Doofenshmirtz causes the Danville dam to flood again ("Oil on Candace").
As is typical of some variations of the Evil Jingle, "Doofenshmirtz Out in the Forest!" in this episode is in a much higher key than the normal jingle (6 semitones higher).
Perry breaks the fourth wall by looking at the screen unamused when Doofenshmirtz explains his "BO-AT".
This is one of the few episodes where Linda sees (and participates in) Phineas and Ferb's plan.
This is the first episode to not have the "Too Young" line, Ferb's Line, "Whatcha doin'?" line, and Perry's lair entrance. The second one is "Run, Candace, Run".
It is revealed that Major Monogram likes limericks.
This is the fourteenth episode where Candace doesn't try to bust her brothers, and the second episode of season 2 overall.
Although Gretchen has been seen with regular eyes many times, this is the only time in the entire series she is seen with a combination of eye styles.
Doofenshmirtz's toilet video is played in the Milo Murphy's Law episode "Disco Do-Over".
According to that episode, the video had already gained 7.3 billion views.
Although it was not shown on camera, this is the first time Phineas, Ferb, Isabella, Buford, Baljeet, Linda, and the Fireside Girls got affected by Doofenshmirtz's inator.
This is the first time Candace changes her size in the series.
This is also the only time Candace has height angst in the series.
Assuming that Candace grew to exactly 50 feet tall as a result of exposure to the growth elixir, she became 8.824 times as tall as she was when the day began. Likewise, the Earth and the rest of the objects in the universe are now also 8.824 times larger than they were. Nobody notices because all measuring devices have grown by the same amount - as Einstein pointed out, everything is relative.
This is one of few episodes where Stacy appears in person, but her name is not spoken once.
Dr. Doofenshmirtz tells Perry that he went to his cousin Gertrude's baby shower. Gertrude is also Candace's middle name. ("Fireside Girl Jamboree", "Hip Hip Parade")
This is one of the rare times Phineas and Ferb are laughing at Candace (or at least trying not to).
Phineas says the growth elixir only works once, which explains why Candace stayed the same size that she already was after the full effects of it while the rest of the universe grew.
This is one of the times in the series where Candace tried to bust Phineas and Ferb for something that was actually her own fault, as she used the growth elixir they created on herself after taking it from them without their knowledge or consent.
While Linda is in the book store talking to Candace on the phone, the "elevator music" version of "I'm Lindana and I Wanna Have Fun!" is playing in the background. It then turns into "Gitchee Gitchee Goo" in the same scene.
Perry shows ambidexterity as he switches the hand with which he wields the hot dog in mid-fight.
The woman watering the lawn was previously seen at Mount Rushmore ("Candace Loses Her Head").
Phineas and Ferb follow the adage of setting free what you love just as they did with Conk the caveman in ("Boyfriend From 27,000 B.C.").
Candace presents the empty backyard with her eyes closed, but after the shot of Phineas and Ferb, Candace's eyes are immediately open without any showing of that happening ("Flop Starz", "I Scream, You Scream", "One Good Scare Ought to Do It!").
When Candace said "tada", the musical "sting" played is the same "sting" that plays in:
The image of Phineas and Ferb playing electric guitars with Candace peering behind them was used on a Phineas and Ferb lunchbox.
Doofenshmirtz uses the phrase "You forced my hand" for the second time. ("Flop Starz")
Phineas and Ferb's invention disappears, reappears, and disappears again ("One Good Scare Ought to Do It!"), though it does it many more times this episode.
This is the first time one can see a living fish inside Phineas's fish tank. This may be Goldie, their goldfish ("Backyard Aquarium"). Although, it may not be it because they also let their pet goldfish go. Strangely enough, the fish in this event multiplies into 2 in the next event the tank is seen, only this time, it somewhat looked like a glow-in-the dark plastic toy stuck to the tank ("Oh, There You Are, Perry"). In the song When You're Small, the goldfish was mentioned ("Hide and Seek"). In a later date, the fish disappears, leaving the tank empty ("Not Phineas and Ferb") but then show up again as toy-looking fishes ("Brain Drain").
Isabella says "Whatcha eatin'?" again ("Hail Doofania!").
In the part wherein Phineas says "So, are we pairing the chicken entrée and the soup?", this may be what Irving, in a later event, was referring to. Although, this is very unlikely because the picture was taken inside the house, not in the restaurant ("Hide and Seek").
This is the fourth time Doofenshmirtz has dated a woman since his divorce. The other three were when he tried to erase the messages off one woman's machine ("I, Brobot"), the other was a blind date and the third was mentioned by Heinz as the one that kept stabbing him with a fork both which were during the Bigfoot events ("Get That Bigfoot Outa My Face!").
Horseback riding: Candace ask Jeremy what he has planned for them that night, one of them including horseback riding which Stacy and Jeremy kept on wanting to do in a dream ("Phineas and Ferb Get Busted!").
This is the second time Candace sees Doofenshmirtz. The first was when she was hallucinating ("The Ballad of Badbeard").
This is the first time Buford and Isabella interact with Doofenshmirtz.
This is one of the other times Phineas sees Doofenshmirtz.
Heinz Doofenshmirtz is the second person to have a definite height. He tells his date he is 6'2" tall but slouches. The first is Candace who is 5'8" ("Attack of the 50 Foot Sister").
Doofenshmirtz's girlfriend mentions that she is usually attracted to blond men, possibly referencing Doofenshmirtz's original appearance. ("Original Pitch")
This episode reveals Doofenshmirtz has an evil tattoo. Although it is not seen in future episodes, even in the instances when he is in his underwear such as in "The Remains of the Platypus".
The man offering to buy Chez Platypus looks exactly like the host of three different shows: The Next Super American Pop Teen Idol Star (although, he was covering a story about it), and the program Phineas and Ferb are watching about cavemen. He is a constant reused animation ("Flop Starz"' "Boyfriend From 27,000 B.C.").
This episode reveals that Buford can play the violin.
The love satellite made by Doofenshmirtz crashing may refer to when her Linda told Candace that if a satellite crashes on the house, she's in charge ("Rollercoaster").
During the "My Ride in Outer Space" montage, Ferb is shown driving the spaceship around the sun, showing that this is the fourth episode where Phineas and Ferb characters have been to space. ("Rollercoaster") ("Unfair Science Fair Redux (Another Story)") ("Out to Launch")
The calendar in Mitch's ship has the same number of days and starts on the same day as the calendar Candace holds up in "Dude, We're Getting the Band Back Together", even though they do not live on Earth.
This is the second time the boys make something not "street legal', the first time being the chariot race. ("Greece Lightning")
This is the first episode wherein the sub-plot causes no development (or counter-development) at all to the main plot, not even indirectly. (This excludes the episodes where the main plot causes development to the sub-plot.) In fact, the ending of this sub-plot isn't even seen, as Doofenshmirtz doesn't even 'Curse' Perry.
This is one of the rare times that Earth is seen in animated form. Most times, a live action earth planet is used when Earth is seen from space.
Buford and Baljeet are the fifth and sixth characters to be shown in underwear. The other characters being Dr. Doofenshmirtz, Phineas, Ferb, and Perry.
This is the first episode that Doofenshmirtz has a back-story that has no in-depth effect on his life.
The Paper Pelican takes flight by lifting itself off the ground into the sky; in real life, a plane needs to build up speed on a runway before taking flight. Though this can be explained by Phineas and Ferb's unexplainable physics when it comes to their inventions: the Paper Pelican was somehow able to simply tilt upwards and launch.
The girl whose sitting in the first row of the plane is one of the "kids that's going to have a conniption". ("Are You My Mummy?")
The girls from Shimmy Jimmy Toy commercial appear again dancing with the Fireside Girls. ("Toy to the World")
Candace writes "C+J" in a heart while brooding about what will happen if they don't go back home the same way Jeremy signed Candace's cast. ("It's About Time!")
In one scene, a teen seen in "S'Winter" re-appears.
Other than Isabella, Katie is the only Fireside Girl to speak in this episode.
When Buford says "If a girl's in, I'm in!", implying that he underestimating any girl participants who competes against him. This was previously happened before ("Got Game?").
In this episode, despite Candace always having a disagreement with Phineas, she seems to value his opinion of her.
When we see Katie with broken arms from the lemonade stand, the Fireside Girls jingle plays off-key.
The Giant Floating Baby Head reappears again, passing a window while Candace is talking on the phone with Stacy.
Dr. Doofenshmirtz finds his information on seismic activity on Carl's website, which Carl had mentioned to Perry and Major Monogram earlier in the episode.
This is the only episode Phineas and Ferb ask money for a ride in their invention apart from the rollercoaster (as shown when Phineas states that they should have charged more).
However, Phineas & Ferb did make money when they were hired as directors in "Lights, Candace, Action!" and Buford made money off of their show in "Out of Toon."
During "Phintastic Ferbulous Car Wash", Isabella is first seen in her Fireside Girl clothes, followed by her signature pink outfit, and then a raincoat, but for most of the episode, she is wearing her Fireside Girls uniform.
The car Jeremy drives is a mid-1960's Ford Falcon Futura.
This episode is one the rare moments in which Doofenshmirtz calls Perry by his first name.
The Cyrillic script on the Doofenshmirtz family's refrigerator translates to "Coldbox."
Jeremy vows to Candace that she will be safe from what she gets scared of and the two embrace. ("Bowl-R-Ama Drama")
The giant shoe from the "Un-Stuck-inator" is similar to the "Who's Blinded by Sand-inator", otherwise known as "Who's Crying Now-inator" ("The Flying Fishmonger").
Things seen on the floors of the D.E.I. building when the sphere of compressed nitrogen molecules crashes through them:
People working on laptops. There is a bookcase and a large graph, so it could be a library.
Two old men sitting in an animation studio. It could be the show's animators.
This is the second episode in which Doofenshmirtz had actually succeeded in his scheme (making mountains out of molehills, literally). The first episode was "Hail Doofania!".
Bab's Beauty gets seen when the molehills start growing ("The Magnificent Few").
Star-nosed moles are found in Canada and north-eastern USA, so Danville might be near there.
When Doofenshmirtz finds out that the Mountain out of a Molehill-inator is working, the Mr. Slushy Burger stand in the forest gets seen ("Rollercoaster").
This is the second episode with Perry's name in the title.
This is the final appearance of Phineas and Ferb's original pajamas.
This is the first time Phineas and Ferb worry about Perry when he goes missing because he left in the middle of the night. He's always home in the morning.
This is one of the episodes where someone says the episode name.
The backpack that Perry is wearing when he is leaving is similar to the one he had on when he delivered chicken wings to Doof in "The Lake Nose Monster".
The fourth wall is broken when the Regurgitator introduces himself, and Doofenshmirtz wants him to know where the thunder is coming from.
A running gag for this episode is when the Regurgitator says his name, and thunder crashes behind him.
Since this was paired with "Oh, There You Are, Perry," they were both about characters (Namely Phineas, Ferb, Candace, and Baljeet) worrying about Perry being lost.
When Phineas, Isabella, and Ferb are first seen, they are wearing sailor outfits. But when they are seen again and in the rest of the episode, they are in their normal clothes with lifejackets.
In addition to "Storm Warning," the Fireside Girls manual shows flag symbols for "High Sea," "Bermuda Triangle," "Pirates," "Calm Sea," "Bermuda Shorts," "Clear Sky," "Piranhas," and "New Wave."
The clothes that Carl is taking from the laundry in his song are Monogram's common uniform and the Hawaiian shirt that he (Monogram) was wearing in "The Best Lazy Day Ever".
Second time when someone says "Where's Perry?" and does something about it ("Oh, There You Are, Perry")
This is also one of the rare cases where Doofenshmirtz defeats himself.
Third time that Phineas gives any indication of feelings for Isabella by inviting her on the cruise. The previous ones are in "Gaming the System" and "The Chronicles of Meap".
Two snippets of this episode are seen in the "Phinabella" montage in "Last Day of Summer".
This is one of the few times Phineas gets annoyed.
Candace doesn't try to bust her brothers because Stacy tells her to stop in this episode. Or because they didn't do anything actually bust-able here.
Phineas and Ferb do not build anything spectacular, however they do use 2 handheld earplugs which they presumably made.
Even though Baljeet says he can't say "F", he almost immediately says "Fail Wail". But this is probably because when he tried to say "F", he had it in mind that it was a bad grade. But when he says "Fail Wail", he had it in mind that it was a song.
As Major Monogram is acting for Carl, at the start, the tune of the piano from Doofenshmirtz's trap is played, except faster. ("S'Winter").
This is Coltrane's third appearance, and his first by name.
One of the kids watching the mime Candace ran over is in the front row during the song Gimme a Grade. Also, one of the 2 Guyz N the Parque members appear in a cameo while the Baljeatles sing Gimme a Grade. ("Comet Kermillian")
Perry never takes off his diaper, even though it's soaked with milk from his bottle.
When Doofenshmirtz is flying over the concert he says "Wait, is that the Baljeatles?", and the invention he happens to be strapped to also explodes into heart-shaped fireworks, just like what happens at the Love Händel Reunion Concert. ("Dude, We're Getting the Band Back Together")
First time the "Oh, there you are, Perry" line isn't said.
Doofenshmirtz forms an army of babies, similar as he did with the army of pigeons and the army of robot penguins. ("Tree to Get Ready", "Bowl-R-Ama Drama")
When Phineas is looking at the magazine, one of the ads says "Glow in the dark Gnome", a possible reference to the gnome disappearance ("Lawn Gnome Beach Party of Terror").
Suzy's theme music is heard when Dennis is on his pet mode.
This is the first time Perry's subplot is the main one.
When Candace tells Dennis to do the robot, a small portion of "Phinedroids and Ferbots" is played.
When Phineas tells Ferb that they need "A 14-inch pipe-wrench, a blow torch, and a jar of mayonnaise!", it is similar to his line "We're gonna need a blow torch and some more peanut butter!" ("Rollercoaster").
Buford makes a cameo in "X-Ray Eyes", but doesn't say anything.
During “X-Ray Eyes,” when Phineas and Ferb are looking through the walls of houses, what appears to be a grown family of the “Baby alien” species can be seen levitating a cow.
This is the first time Doofenshmirtz defeats himself.
This episode is the first one to show Phineas actually wondering what happened to the invention of the day.
Adyson is the only Fireside Girl who does not appear in this episode.
Doofenshmirtz says "I'm going to have to do the right thing here, aren't I?", just like Candace at the end of "The Lake Nose Monster". The crowd around him goes "Aww," just like they did when he saved the kitten in "Voyage to the Bottom of Buford".
The giant bone appears in the present, when it is about to be displayed; future, in the same location; and altered future, on top of the time machine in the city dump.
This is the second time Perry and Doofenshmirtz are seen as elders ("Lights, Candace, Action!").
Carl still works at O.W.C.A., which means he must have been hired after his internship.
In the alternative future, Doofenshmirtz changes everyone names to Joe so he doesn't have to remember any names, similar to when he names his crocodiles "Susan and Susan" ("The Ballad of Badbeard").
Candace shimmies up the holographic tree in the same way she does in "Backyard Aquarium".
Linda's line, "You two are in so much trouble", echoes Candace's line, "Those two are in such big trouble", from "One Good Scare Ought to Do It!".
This is the third two-part episode where Lawrence does not appear ("One Good Scare Ought to Do It!", "The Chronicles of Meap").
This episode was named #7 on WatchMojo.com's Top 10 Phineas and Ferb Episodes.[2]
Isabella goes to the past and gives Phineas and Ferb the steel-wood fuser they need, inadvertently creating a temporal paradox. There are many other paradoxes in the episode, most of which are hand-waved away.
Future Phineas and Ferb are not shown, but they are mentioned. Phineas is in Switzerland to receive an award, and Ferb is in Camp David.
Candace has three children, identical to her own family, two sons, Xavier and Fred, and a daughter, Amanda, and it is implied that she and Jeremy have gotten married.
Perry is alive in the future, still battling Doofenshmirtz but at checkers.
Isabella becomes the aunt of Candace's kids, meaning that Isabella ends up marrying Phineas or Ferb as an adult.
The events of the future Phineas and Ferb episode "Act Your Age" implies that she will likely marry Phineas.
The introduction reveals Major Monogram's first name: Francis.
Candace appears in the videos of all the top 10 songs except for "Ain't Got Rhythm". Her voice appears in eight of the ten, the other two being "Ain't Got Rhythm" and "Little Brothers".
Irving makes a brief cameo in the in-between segments. In production order, this marks his first appearance.
Perry isn't in any of the clips (excluding Gitchee Gitchee Goo).
First episode where Phineas and Ferb haven't been shown full on screen (although the two make a speaking cameo appearance and seen through the videos).
Doofenshmirtz says "It's working, it's working!" exactly the same way he said it in "At the Car Wash".
Isabella's outfit keeps switching from her normal outfit to her Fireside Girls uniform during the extended "Gitchee Gitchee Goo". This is probably due to the fact that parts of the old video for the song were re-used in this extended version. Also, the background changes from "Phineas and the Ferb-Tones Reunion Concert" to "PFT".
Baljeet mentions that Phineas told him to "seize the day", which is part of the lyrics in the extended version of the theme song, "Today is Gonna Be a Great Day".
In the beginning, Isabella is seen in pajamas, which was also seen in "I Scream, You Scream". However, this time their color matches that of the bow on her head.
This is the only time Isabella’s pajama color matches her purple bow rather than pink. Her pajamas had been already pink in "I Scream, You Scream", and they would go on to revert back to their original color next timeshe wears them.
This is the first episode where every Fireside Girl has a speaking role.
Gretchen, however, speaks the most besides Isabella, making her role more prominent.
This is the second episode when the Fireside Girls have extended dialogue (the first being "Bubble Boys").
This episode reveals that Ginger has a crush on Baljeet.
This episode marks the second appearance of Wanda Acronym, Pinky's mission dispatcher.
This is the first episode to have Isabella go into Phineasland.
This is the third episode to use the "hearts in eyes" technique. In this episode, Isabella imagines Phineas with hearts in his eyes when he "confesses" to her. In ("Rollercoaster"), she is seen looking at him with hearts in her eyes. Candace also used hearts in her eyes looking at Dennis in "No More Bunny Business".
This episode substitutes a Perry plot for a Pinky plot, since the main plot is about Isabella instead of Phineas and Ferb.
However, it cuts to "Lindana" in the middle of "Gitchee Gitchee Goo".
In the close-up of Isabella's sash as the girls say "We wear our patches upon our sashes", an "I Just Saw A Cute Boy" patch can be seen. This is most likely referring to Phineas.
The place Prof. Poofenplotz's Me-Mobile is stuck is around the place Dr. Doofenshmirtz parks and goes to the science fair ("Unfair Science Fair").
This is the second time the Fireside Girls had to use their sashes to get them out of a dangerous situation. The first time was in "One Good Scare Ought to Do It!" when they rescued Phineas from falling.
This is the second time someone mentions a "cute little tree", the first being Phineas ("At the Car Wash").
Isabella uses big pleading eyes in this episode, and for the first time. This is the second time a Fireside Girl (counting Isabella) uses this, and the first was Katie and Gretchen in "Don't Even Blink".
This is one of the few 23 minute blocks where Candace doesn't try to bust Phineas and Ferb in either episode.
Cheer Up Candace/Fireside Girl Jamboree is also the first pair of episodes without Linda.
Isabella pulls out a Tween Bleep magazine, which is like the Teen Preen Magazine Stacy and Candace have read in the past in "Don't Even Blink".
Agent E, who helped carry Perry to the top of the tree to receive his mission while at Camp Phineas and Ferb in "The Ballad of Badbeard", returns to arrest Agent P.
This episode reveals that Stacy does not know what airline food is.
This episode was mentioned in a Phineas and Ferb magazine, on the jokes page, Stacy was shown with a speech bubble that says 'What's airline food?'. Underneath that, it says, 'To find out why Stacy said this, watch the episode 'Cheer Up, Candace'.
The first time the Mix and Mingle Machine song shows Phineas and Ferb together, they are seen doing the same step as they were doing in the song Technology vs. Nature from "Perry Lays an Egg".
This is the second episode where someone is hit in the groin, though it was not shown onscreen due to censorship. ("Raging Bully")
This is the second time Phineas mentions ice cream for someone. The first was in "I Scream, You Scream".
Doofenshmirtz makes clones and one of them is defective. A similar event happened in "Run Away Runway".
Second time Doofenshmirtz's invention is aimed at the Fireside Girls ("Don't Even Blink").
Doofenshmirtz is shown to have ordered cupcakes from the Fireside Girls, ironically, he attempted to tear down their factory bridge.
Similarly to "Get That Bigfoot Outa My Face!", Phineas uses a checklist whenever Accomplishment Patches are earned by a Fireside Girl (Candace in this case).
Third time Phineas and Ferb built a rollercoaster. ("Rollercoaster", "Phineas and Ferb-Busters!")
This episode took place after "Rollercoaster: The Musical!" due to Phineas mentioning that they're building a second rollercoaster in that episode; this episode and "Phineas and Ferb-Busters!" feature a rollercoaster, too.
Phineas gives instructions in Spanish again ("At the Car Wash").
This is at least the second time Candace and Doofenshmirtz have met. The first time was in "The Ballad of Badbeard". However, this time, Candace is far more lucid.
Mr. Slushy Dawg was founded the same year as the infamous stock market crash. It is unknown whether this was intentional or not, but it is probably why "it never gets better."
This is one of the few episodes to have Doofenshmirtz address Agent P as Perry instead of Perry the Platypus.
The Doof and Perry plotline only has three scenes (Agent P receiving his mission, Perry getting trapped and the inator, and Perry hurting both of Doof's feet) due to the focus on the Buford/Baljeet and Candace/Stacy stories.
The show's Theme Song can be heard when Candace is on Phineas and Ferb's contraption.
This is the second time Candace yells so loudly at someone that it messes up their hair, the first time being "At the Car Wash".
During the scene where Doofenshmirtz "wore all that fringe" in Not So Bad A Dad, Doofenshmirtz is wearing the same outfit he wore when he was singing Yodel Odel Obey Me in "Bubble Boys".
The man with the accent, who also appears when Doofenshmirtz "goes out of his way to catch that foul ball", is one of the people watching the concert Phineas and Ferb host to bring home Perry in "Oh, There You Are, Perry".
Balthazar Horowitz makes another appearance, during the "foul ball" flashback.
The Retro Pharmacist Emporium from "Run Away Runway" was seen in this episode.
Norm appears for the second time in Season 2. His last appearance was in "At the Car Wash."
This is one episode where Doofenshmirtz does not create or use an "inator" against anyone.
Doofenshmirtz notes that Norm made a lot of potato salad, similar to when Stacy notes on Linda's plans for purchase, "Wow, that's a lot of potato salad" ("Vanessassary Roughness").
The outfit Candace wears to the show is a pallet swap of the outfit she wore in "Comet Kermillian". She wears a pink T-shirt instead of a white T-shirt, a pink belt with a gold buckle instead of a white belt with a gold buckle, white bootcut jeans with yellow pocket designs instead of blue bootcut jeans with yellow pocket designs, and her normal shoes with pink socks instead of her normal red socks.
Second time a bag of manure gets used ("I, Brobot").
This is the third time Candace doesn't see the Big Idea ("De Plane! De Plane!", "Hail Doofania!").
Ferb's comment, "Perhaps the lost city of Atlantis wanted to stay lost" echoes Phineas', "He must not want the world to know he really exists" ("The Lake Nose Monster").
Santa Claus is responsible for the events of this episode.
Throughout the majority of the series, Phineas' height is less than Isabella's. However, possibly because this episode occurred AFTER summer had ended, Phineas had a growth spurt, and is seen as about the same height as Isabella.
This episode is the first one to not take place during the summer.
All Christmas wishes that are known were granted:
Phineas - To be just like Santa Claus
Ferb - A Harmonica
Buford - To be thought of as a good person by his friends.
Perry: A new bowl (from Phineas and Ferb), a vase (from Doofenshmirtz), and a Sal Tuscany Christmas CD (from his Secret Santa who is really Santa Claus; not Carl).
Doofenshmirtz: Almond Brittle (from Perry the Platypus) and the ability to hate Christmas.
Monogram: A nice picture of him and Carl (from Carl).
Carl: A signed picture of Monogram, saying "To whom it may concern, Merry X-mas" (from Monogram).
Ferb, when one realizes it, got his harmonica on Christmas EVE, not Christmas Day. Although news presses regularly insert breaking news as the paper go to press, potentially past midnight making it Christmas Day 1 second past 11:59:59PM Christmas Eve.
Baljeet may have some affection for Wendy because he acts shy around her and kisses her. He also saves her present.
Dr. Doofenshmirtz has an Uncle Justin hiding in Barneo. Although, the plans for the "Naughtyinator" are really from Santa Claus so Uncle Justin may be elsewhere!
It is still unknown how the book Oh, Christmas Tree! fits in with the events in this episode.
When the Sal Tuscany CD breaks, Doofenshmirtz notices the letters are an anagram of "Santa Claus with an embarrassing extra 'Y'". "Sal Tuscany" is an anagram of "Santy Claus", similar to the name "Sandy Claws" in The Nightmare before Christmas, but the writers seem to have used "A Sal Tuscany" for the anagram instead. At the end of the scene Doofenshmirtz exclaims "Sal Tuscany is Santy Claus?"
This episode reveals that Candace can play the contrabass. (Although prior to this episode, it may have been obvious since "Mom's Birthday" reveals that she can play the bass guitar, which is basically a guitar-sized clone of the double bass.)
This special further confirms Isabella is at least part Jewish, as she affirms her celebration of Hanukkah.
Isabella says that she writes letters to Santa in the beginning, but later she says that she doesn't celebrate Christmas and that she celebrates Hanukkah. She may have just said that to help Phineas' point, or she may be half-Jewish. (If one's mother is Jewish, then they are considered a Jew as well.) Although, Garcia is a common Hispanic surname (and typically the maiden name in her name configuration while Shapiro is a relatively common Jewish surname.) This could also mean that Isabella does not celebrate religious Christmas, just commercial. Santa Claus is generally considered a more commercial part of Christmas, not tied down to a particular religion.
Candace called Jeremy "her little drummer boy" and "her little town of Bethlehem". Since "The Little Drummer Boy" and "O Little Town of Bethlehem" are Christian Christmas carols, this may signify that Candace and, presumably, the rest of her family, are Christians.
In this episode, Isabella, Candace, Grandpa Fletcher, and Grandma Fletcher are the only ones who wear their regular outfits. Although Isabella, Candace, and Grandma Fletcher also wear winter outfits in outdoors scenes.
Vanessa, Stacy, and Gretchen do not appear in this episode, although Olivia Olson, who voices Vanessa, is heard singing "That Christmas Feeling", and Stacy is mentioned when Candace is talking on the phone. Stacy also has a cameo appearance in the extended version during the song "What Does He Want?".
Isabella's voice is slightly higher pitched every time she sings in this episode. It could just be because she sings using a different voice than "Ballad of Badbeard" and "In the Mall".
This is one of the rare chances to see Phineas angry, or just plain old unhappy.
Santa Claus uses the Yiddish word "shvitz," which means "sweat." This usage, combined with the stereotypical Yiddish music that plays as he says it, may imply that Santa is at least part Jewish.
While the kids are singing "Danville for Niceness", Phineas is looking bored until Isabella comes in shot, then he looks at her with admiration. This suggests some attraction between the two.
This is the second time Buford is seen with a baseball bat. ("Swiss Family Phineas")
Doofenshmirtz, after tying up Perry, placed a partridge on his bill and sang, "And a partridge on a Perry. The platypus!" Coincidentally, the name "Perry" actually does mean "pear tree".
A running gag in this episode is that Isabella, Baljeet, and Buford are saying the same thing at the same time.
Both the Yeti in the shower and the Yeti being carted into the backyard past a gossiping Candace are direct parodies from the regular opening credits.
When Buford comments on the "cool clubhouse", the melody from "S'Winter" can be heard in the background.
When Baljeet says "Well? Aren't you going to ask me what my Christmas wish is?" it could be a nod to "Mom's Birthday", when Candace says nearly exactly the same thing.
Dr. Doofenshmirtz is wearing panda slippers, likely an homage to Peter the Panda, his temporary "other nemesis", who appeared in "It's About Time!". He's also been seen wearing them in a handful of other episodes ("Comet Kermillian").
This is actually the third time one of Doofenshmirtz' plans actually succeeds in any measurable degree (first was in "At the Car Wash", second was "That Sinking Feeling"). This scheme lasted for the majority of the episode, but this was also the first plan Perry himself did not foil, but rather Santa (disguised as Sal Tuscany). Santa may have given Doofenshmirtz the plans, as well. (It can also be considered that his scheme in "Dude, We're Getting the Band Back Together" worked, because he made a party for his daughter, also in "Finding Mary McGuffin" because he found the switch).
Candace's explanations about idioms (by mouth I mean Jeremy) in the same way that Doof said "by fire I mean Perry the Platypus" ("Cheer Up Candace") and Monogram when he denied Agent P's vacation ("Put That Putter Away").
When Candace says "Whatcha doin'?" to Jeremy in her phone, Isabella is across the street in her house and reacts to it being said by someone other than herself. This is the second instance of long-distance perception, the first being when Doofenshmirtz felt a "disturbance in the cup stacking universe" ("Thaddeus and Thor").
This episode marks the return of Suzy Johnson ("Crack That Whip", "Comet Kermillian" et.ali.). However, she does not have an active part in the story nor does she have any speaking lines. She only gives Candace an angry glare when she came over to visit Jeremy.
While Phineas and Ferb use the same pajamas as in "Chez Platypus", they are different than the ones used in the first season. Phineas and Ferb use these pajamas from season 2 onwards.
This is Vincent Martella's favorite episode.
This episode was named as an "Honorable Mention" on WatchMojo.com's Top 10 Phineas and Ferb Episodes.[3]
This episode was Number One on ScreenRant's Top 10 Best Disney Animated Christmas Specials.[4]
Up until July 17, 2020, only the edited version was available on Disney+. On that date, the extended version was added.
On April 30, 2025, this episode was bizarrely the final Phineas and Ferb episode to be shown on Disney XD Netherlands before its closure.
Second time Candace attempts to bring evidence directly to Linda ("Bowl-R-Ama Drama").
The librarian from "Phineas and Ferb's Quantum Boogaloo" is seen, but has a different voice, likely due to the fact that she's 20 years younger than in that episode.
Doofenshmirtz's schemes is a reversed version of his schemes in "Fireside Girl Jamboree". In this episode, he plans to changes food supplies into junk foods.
According to Dan Povenmire, "Tiana is actually named after my sister Tiana. I named Mom after my sister, Linda, and I only felt it was fair to create another character for the other one so she wouldn't feel left out. [The Disney movie] Princess and the Frog having a Tiana was just a happy accident."
The Venus fly traps looks like the evil plants from "Atlantis".
Lawrence discovers something related to the O.W.C.A. apart from Perry the Platypus. ("Comet Kermillian")
This is the second time Lawrence discovers Perry's life as a secret agent, the first being "Phineas and Ferb Get Busted!". But this time, after he trips over a cord and goes into the memory eraser, he doesn't remember anything, even Perry's secret.
Major Monogram says "Great googly moogly" again.
Second time robot versions of Phineas and Ferb are seen. ("I, Brobot")
This is the only time Suzy is nice to Candace, and explains the reason for her usual bad treatment of her control of Jeremy.
This is one of the few episodes that someone says "What'cha doin?" three times, which is unusually frequent; all the lines are said by three different characters (Isabella, Suzy, and Candace).
When Suzy and Candace are walking up to the gang, Baljeet, on Buford's shoulders, is using a hammer. However, after the camera zooms in on Isabella, Buford and Baljeet are noticeably absent. This may have been an error, or could be explained by Buford's fear of Suzy ("One Good Scare Ought to Do It!")
When Candace says "yes", the way she says it is reminiscent of the Mexican/Jewish photographer from "Picture This".
This is the first episode that Phineas orders his mom to do something like Candace.
Also, when Carl's disguises are being shown, an extract from his theme song (Carl, the Intern) plays.
First episode in which Carl is the main character.
This is the first episode where Carl and Major Monogram directly interact with Phineas, Ferb, and their friends.
Perry once again does not interact with Dr. Doofenshmirtz, the first being "No More Bunny Business". Instead, his mission is to find a missing agent named Agent G.
First, so far the only episode with Carl's name in the title.
During the montage where Carl is trying on different costumes before going undercover, he dresses as several characters that have been seen in previous episodes:
The to-scale pink bunny costume that may had came from "Boyfriend From 27,000 B.C.", when Carl and Monogram told Perry to do his mission dressed as a big, pink bunny.
The costumes of the Village People that were previously worn by Candace in "Flop Starz" reappear on Carl.
Phineas and Ferb consider "that pesky gravitational pull" in the same way as the "flying car of tomorrow, today" had a pesky "pull to the right". ("Phineas and Ferb Get Busted!")
The tow truck Dr. Doofenshmirtz bought is very similar to one that towed away both his Anti Gravity Evil-Launchinator and Norm ("Undercover Carl").
When Buford and the other nerd are on the rooftop, the music during the scene where the pigeons are getting ready to poop on Roger Doofenshmirtz plays ("Tree to Get Ready").
This is the second time Baljeet saves Buford's life ("The Bully Code").
This is the second time someone says "You're dead to me!" The first being Doofenshmirtz in "It's About Time!"
Candace is actually in Doofenshmirtz's lair for a couple of seconds.
This episode reveals that Carl was born without nostrils (which is ironic, due to his voice being rather nasally).
The arcade game in this episode is one of Perry's secret entrances that could have been easily accessed by anyone because anyone could've placed a quarter (or a special coin, possibly given in the counter) and entered his lair by accident.
Phineas and Ferb don't interact with their friends.
This is the first episode where Perry enters his lair without someone saying "Hey, Where's Perry?"
"Adam and Eve on a raft, wreck 'em" in diner lingo means "Two scrambled eggs on toast."
The episode marks the first time any of Buford's family members are seen (his mother, Biffany is shown) and the first time any of Irving's family members are seen (his brother, Albert, and his mom).
This is the first time Candace hurt Phineas and Ferb. She did so by pulling their faces, thinking they were Buford and Baljeet.
This is the first episode Doofenshmirtz says the Leaning Tower of Pizza.
Major Monogram calls Agent P Perry for the second time ("Toy to the World").
This is the second time that Candace recruits help to bust her brothers ("Leave the Busting to Us!").
On DirecTV and some cable systems, it is stated that this episode is broadcasted before "Not Phineas and Ferb", even though the pairing is the opposite.
This is technically the longest time (in-universe) that Candace says her "But but but" catchphrase, as near the beginning of the episode she says it for so long that it goes from day to night and back to day again.
Isabella says "Hey, where's Perry?" again. ("Cheer Up Candace").
Second time a human/animal is a giant, as Steve is supposedly 40 feet tall. First was Candace Flynn, who was 50 feet tall in ("Attack of the 50 Foot Sister", third if counting Candace as the Control Freak being be 50 feet tall in "Out of Toon").
The way that Candace and Steve grow is also similar: certain body parts grew disproportionately compared to the rest of their body.
The guitar solo is quite similar to the chase scene guitar solo when Phineas and Ferb tried to capture a mummy ("Are You My Mummy?").
This episode is Ferb's largest speaking role and his longest timed line lasting 46 seconds, beating his line in "It's a Mud, Mud, Mud, Mud World", which was 7 seconds long and "Where's Perry? (Part Two)" lasting about 14 seconds.
This is the second time Ferb has extended lines ("It's a Mud, Mud, Mud, Mud World").
This is the first time Ferb speaks in a long poem.
During his speech, Ferb breaks the fourth wall when he says that will not stop their search for Steve after only 11 minutes, the average length of a normal episode.
Chairs are used several times throughout the episode: Carl shreds a chair; KPP is hit with a chair twice by his wife; Perry throws a chair at Dr. Doofenshmirtz.
Candace's supervillain giraffe suit might be a self-referential joke on how long her neck is.
It seems that Phineas has problems lying to Isabella, but not Candace or Linda. He can be seen speaking nervously and scratching his ear when lying to her during this episode.
The phrase "Thank you very much" is said ten times. Nine times by KPP, and once by the Dangiraffe (Candace). This phrase was also said by Isabella in "Hide and Seek", but in a genuine manner.
First episode Isabella is never seen with her bow on her head.
This is the first time Ferb shows annoyance by one of Phineas's ideas (with the "Bulgarian folk dancing" being a "function" of The Beak).
Everybody was crediting Phineas for being a good superhero, but Ferb appears to be the one doing most of the movement and weapon release (for most of the weapons).
In "The Fast and the Phineas", Perry's hovercar is shown coming out of the tree, so when Phineas and Ferb built their "Nest" hideout, they should have stumbled upon Perry's lair.
This is the first time a character is knocked unconscious, unless the time in "Lawn Gnome Beach Party of Terror" when the coconut fell on Candace's head is counted.
This is the second episode where Isabella wears a fedora. The first time was at the episode "Rollercoaster", where she was wearing Perry's fedora when Perry unexpectedly drops in the rollercoaster.
Phineas and Ferb wear The Beak suit the same way they wore a suit of armor in ("A Hard Day's Knight").
Lewis, who gains a wife, a promotion, and a full head of hair upon learning what an aglet is, is one of the cheering fans after The Beak destroys the falling Bango-Ru sign. ("Tip of the Day")
The Beak is repeatedly referred to as the defender of "the best day ever". This refers back to the lyrics of the extended Theme Song.
Phineas pokes out of the egg in the lair with his nose. This could possibly be a jab at how pointy his nose is, and also "Are You My Mummy?", where Perry uses Doofenshmirtz's nose to pop a bubble, to which he remarks, "Is my nose really that pointy?"
The director from The Princess Sensibilities appeared in danger of the falling sign. ("Lights, Candace, Action!")
Phineas says "What's up with the getup?" to Isabella. This is the same line Candace uses to Linda in "Picture This", when she is going to a Mexican-Jewish Cultural Festival.
This was second time that Phineas saves Isabella from danger. First was from the bug eye-bot in "Hide and Seek".
The picture of himself that Doofenshmirtz is standing in front of when announcing his taking-over the Tri-State Area closely resembles his 1914 counterpart.
The 11-minute episode length is referenced again, this time by the narrator at the midway point of the episode.
This is the first episode where Perry does not wear his agent hat during a mission.
This is the second time that Perry has worn an actual set of clothes. The first time was in "Vanessassary Roughness".
The time accelerator in this episode is the second one that Doofenshmirtz has made. The first one was created in "Lights, Candace, Action!", when he wanted to produce some perfectly-aged cheese.
This is first of Phineas and Ferb's Big Ideas where they were exhausted from building and wished to never to do again.
This is the third time that Candace has managed to bust her brothers ("Phineas and Ferb Get Busted!", "Phineas and Ferb's Quantum Boogaloo"), although in each incident, time is modified, or the whole thing turns out to be a dream, making them "not count". This episode (along with "Phineas and Ferb's Quantum Boogaloo") also proves that Linda would not always approve of what Phineas & Ferb do if she was actually aware of their true activities, as she was quick to call them out & was prepared to punish them on the spot. (It is unknown what Lawrence would think, though)
Despite Linda being halfway through saying the word "busted" before time reverses, she does actually say the whole word in reverse.
This is the second episode where the ending shows that the whole episode never happened due to a time lapse. The first was "Phineas and Ferb's Quantum Boogaloo".
This is the first episode that Phineas and Ferb had a long argument in planning the Big Ideas, however it was never shown. However, if their minor argument about Bulgarian Folk Dancing in "The Beak" is counted, this would be the second.
This is the first episode that Candace and Stacy actually argue with each other.
This is one of the few times Phineas and Ferb are charging money for one of their Big Ideas. Other instances of this can be seen in "Rollercoaster", "Chez Platypus", "Out of Toon" (though this was actually Buford scamming admission fees), and "Ain't No Kiddie Ride" (by technicality, since the rides required a quarter).
Adyson is the only Fireside Girl who has a speaking line other than Isabella.
A girl from the Shimmy Jimmy commercial from Toy to the World made an appearance buying lemonade from Phineas and Ferb. ("Toy to the World")
Doofenshmirtz's line "Because then the tiki gods would win!" is a nod to Phineas's line: "Then the morning DJs win." is also from the Lawn Gnome Beach Party of Terror episode as well.
In Part II, it is mentioned that Perry doesn't wear trunks, just like he never wears clothes. (Except his boxer shorts under his fur.) ("Unfair Science Fair", "Perry Lays an Egg")
First episode in which the episode does not include one line in the theme song in at all, but with the logo, the episode's title and the creators Dan Povenmire and Jeff "Swampy" Marsh.
Ferb speaks a total of nine times in this episode, making it the episode where spoke the most frequently at the time of its release. The majority of his lines were in Act IV (the stop in Paris).
The record number of lines was previously held by "Ready for the Bettys" with six lines.
Second episode where someone other than Phineas and Ferb wears their outfits ("Run Away Runway").
When Stacy answers Candace's phone call at 5 A.M., her bow is seen attached to a hairband.
The original Leekspin animation, and as a result, when viewers spotted the Leekspin reference was credited as a reference to Hatsune Miku's original song Ievan Polkka and not Orihime Inoue's Ievan Polkka.
This special seems to take place after all episodes that have aired before it (or at least a good number of them), based on how many references the characters make throughout the episode.
"Pair of ducks" is a play on words (paradox) which also describes Candace's situation. In an episode of Home Improvement, Tim Taylor mistakes the word "paradox" for "pair of ducks."
This is the first time O.W.C.A's name is said in the show.
In the episode, a person who lives in the country speaks English and one of the people in the group speak the native language three times: when Ferb said they are friends of Stacy to Bāchan Hirano, when Candace asked for directions to the hotel, and when Buford asked for cooking oil.
It is proven that Ferb can speak at least some Japanese.
It is also proven that Buford can speak French fluently with a French accent. He has also read Voltaire well enough to quote his works.
Between Buford being able to speak fluent French and his line "Oh, I can't help it, Paris does it to me every time," it is hinted he may have been in Paris before.
This the only hour long special to not be a Season 4 episode.
This episode marks Candace and Jeremy officially becoming boyfriend and girlfriend.
This is also the first time Jeremy and Candace kiss in the series.
This episode marks the first time Isabella cries, due to not having Phineas return her feelings in Paris.
In this episode, Isabella almost reveals her feelings for Phineas.
This is the first time in the series where Phineas has actually doubted that his idea could work, when he was on the island and went insane, being obsessed with trying to get off the island.
It is made clear that Ferb knows about Isabella's crush on Phineas, because when they were stranded on the island, Isabella talked to Ferb about it.
The "Hey, where's Perry?" line is said by Chaka Khan after "I Believe We Can".
Phineas also says this line at the end of the episode, and says "Oh, there you are, Perry" at the beginning, the reverse of the usual pattern.
"Poubelle" is the French word for "trash can". Therefore, the hotel Jeremy is staying at is called "Hotel Trash Can".
Candace and Stacy are seen eating noodles with chopsticks for breakfast. This may be to a reference Stacy's Japanese heritage.
This is proven later in the episode where Stacy has a family in Japan when the group arrived in Tokyo.
When Phineas is reminding Candace of what she has accomplished, an instrumental version of "I Believe We Can" plays.
In O.W.C.A. Files, Wendell suggests that all they need is a big rubber band and to palm trees to launch them, similarly to the scene where they used the paper airplane to get back to Danville.
First episode to never play the theme song or a different version of the theme song.
During a scene in "Bouncin' Around the World", in what appears to be China, a sign that says "Missing bike: Call Rob" can be briefly seen, and it also appears on a lamppost in Paris when Candace is going to see Jeremy.
Phineas breaks the fourth wall when an ad appears over the triangle that Ferb was holding by saying "Hey! Do you mind? We've got a visual gag going on here! Thank you!"
Phineas breaks it again when he says "No matter where we go, Ferb knows everyone" because he looks straight at the camera.
Major Monogram's mouth being moved by someone's hand to make him talk was seen again. First was by Carl in ("Let's Take a Quiz").
Buford saying "I want the bug" may be a nod to the line "I want the mud" in ("Jerk De Soleil").
Ferb folding the giant map to pocket size could be a reference to the time he unfolds a giant blueprint, or when the Wrapped-Up-In-A-Nice-Little-Bow-inator shot their landing pad and it folded up into a tiny parcel. ("The Ballad of Badbeard", "Invasion of the Ferb Snatchers").
One of the teenager seen in the party, who wears pink dress and magenta shorts, is Sara, Jenny's and Django's cousin, thus marking her first appearance. Her name would be revealed later in "Candace Gets Busted".
Ferb sings "Baby, baby, baby, baby" during "Summer Belongs to You" just as he did in "Gitchee Gitchee Goo". ("Flop Starz")
Isabella suggests to give up again, this time from Phineas not noticing her feelings on the island from Paris. ("The Lizard Whisperer")
When Isabella was invited to go with them to Paris, she goes through a line of questions like she did in ("That Sinking Feeling").
Phineas says "Oh yeah!" again when the boat speeds up. Wind is also blowing his face. ("The Fast and the Phineas")
The plane falls apart in water leaving only the seats, which is similar to what happened to the 'Paper pelican' ("De Plane! De Plane!")
When Ferb got on Vanessa's scooter, the background music of the song "Forever Summer" is played. ("Run Away Runway").
The group flying back to Danville in the paper airplane could be a reference to the line about paper airplanes in "When You're Small" ("Hide and Seek").
When Vanessa asks Candace what "Ferb" is short for, she says "I. Don't. Know." in a rather similar way that Lawrence said it in "Phineas and Ferb Get Busted!".
While talking to Candace on the boat, Phineas reminds Candace of several of her past adventures. The dialogue here is similar to a conversation between Stacy and Candace in "De Plane! De Plane!".
This episode is the second use of a statue like the famous discus thrower, Discobulus ("Greece Lightning").
This is the second episode Phineas actually yells angrily at someone, the target this time being Candace. She refused to get on the little kid trike so they can get home. Phineas reminded her that they were running out of time and when that still didn't work, he angrily yelled, "GET ON THE TRIKE!" and it finally worked. This time, however, is the first time where his yelling is actually sincere and not planned, as the last time he had yelled angrily, it was because it was part of his "Big Idea" for the day. ("Flop Starz")
The idea of lengthening time was once mentioned in "I, Brobot": Phineas said that "We either need more days of summer, or more of us."
Second time Phineas and Ferb dress as Italian chefs ("What Do It Do?").
One of the few times that Candace does not attempt to bust her brothers.
As she is about to get on the paper airplane, Candace calls out "I get a window seat!" Later, she is seen sitting in a window seat in" Where's Perry?".
Exactly 20 seconds before the song "Summer Belongs To You" starts, Irving makes an appearance behind Phineas under the "Welcome Home" banner.
In the Milo Murphy's Law episode "Missing Milo", Balthazar Cavendish and Vinnie Dakota have the same conversation about "Flooding It" as Phineas and Ferb did in this episode.
Snippets of this episode are seen during "What Might Have Been" in "Act Your Age" as well as during the "Phinabella" montage in "Last Day of Summer".
This episode was named #1 on WatchMojo.com's Top 10 Phineas and Ferb Episodes.[5]
In the United States, the full episode was posted on the official Disney XD YouTube channel on June 22, 2021.[6] However, it was set to private weeks later.
Isabella is the only one of Phineas and Ferb's friends to not appear in this episode.
This may be the longest time Phineas's "I know what we're gonna do today" line is from the beginning of the episode. He didn't say it until midway through part two.
Major Monogram does not appear as himself in this episode; instead, he plays as a robot rickshaw named R.I.C.K.
Phineas (Although he dressed like a Speckie, he likes both)
This is the first time Irving has shown or even hinted dislike towards Phineas or Ferb.
Doofenshmirtz does not build an inator in this episode.
During Candace's fantasy, the zebra holds up a Candace-based parody of the Barack Obama poster Hope, which also appeared during the rewind in "She's the Mayor".
Baljeet feels a disturbance, similar to Dr. Doofenshmirtz in "Thaddeus and Thor" and Isabella in "Phineas and Ferb Christmas Vacation!".
The Talking Zebra who calls Candace "Kevin" appears ("The Ballad of Badbeard", "Phineas and Ferb Get Busted!").
It's the second time Candace has been laughed at. ("Out to Launch")
Doofenshmirtz is briefly seen watching The Platypus and His Girlfriend in his underwear right before the credits, officially marking the fifth time Doofenshmirtz is in his underwear ("Lights, Candace, Action!", "Tip of the Day", "Bubble Boys", "Phineas and Ferb Hawaiian Vacation"). This is the last time Doofenshmirtz is seen in his underwear in Season 2, but it happens again in the Season 3 episode, "Run, Candace, Run".
Another time where Candace does not attempt to bust her brothers.
This is the first episode where Dr. Doofenshmirtz interacts with Buford, Baljeet, Suzy, Isabella, Phineas, and Ferb. Although this may be unofficial, since it was in a dream.
This is the second episode in which everything was all a dream. First was "Phineas and Ferb Get Busted!". This episode, however, was dreamed by Candace, not Perry dreaming Candace within a dream.
All seven characters who were in the monster unicycle at the end have at least one scene with Dr. Doofenshmirtz in this episode when he is almost never in the same scene as them, and all of them except Isabella have seen Perry in secret agent mode at some point in the story. However, since Candace dreamed all of that up, and she is the only one at the end of the day who still knows Agent P and Dr. Doofenshmirtz, there was no need to erase their memories like at the end of "Phineas and Ferb the Movie: Across the 2nd Dimension".
This is the second time that Candace has seen Perry as Agent P, though both times, she was hallucinating or dreaming about it (or thought that she was). ("Phineas and Ferb Get Busted!")
Doofenshmirtz bangs on the crystal ball to get it to work like he did in his monitor in "Hide and Seek".
This is the first episode when Ferb says the "I know what we're gonna do today" line and Phineas's name, apart from in the song Backyard Beach.
This episode reveals that by this point in time, Phineas and Ferb know Lindana is Linda, but Candace does not.
This is the first episode where Lawrence is shown singing alone.
This episode reveals that Lawrence knows how to play the keytar and the keyboard.
The Charity Girl from "Finding Mary McGuffin" makes an appearance in this episode. Her name was also revealed as Sally.
This is the second episode when Phineas and Ferb don't make something. They just help Lawrence to create a non-existent famous singer of the '80's. ("Tip of the Day")
"Quirky Worky Song" is heard twice in this episode. Once while the gang are gathering materials, and a differently-arranged version is heard during the tour of the building.
Candace and Stacy talk about "thick nerdy glasses" in this episode. In "Flop Starz" and "Robot Rodeo", Candace wore glasses.
Despite the show's frequent stance against "imitable acts of violence", Albert is seen swinging nunchucks in this episode, which is a very dangerous weapon.
Even though Candace and Albert formally met in this episode, Candace had seen Albert with and without the telescope before ("Not Phineas and Ferb").
This is the second time that Doofenshmirtz has attempted to rotate a large space body, the first time being in "Rollercoaster". This time, however, he actually succeeded, although his plan backfired.
This is the second time Phineas and Ferb make a really tall building ("Thaddeus and Thor").
This is the second time a glass trap is broken by a high-pitched voice ("The Fast and the Phineas").
This is one of the few episodes where Perry does not defeat Doofenshmirtz.
In fact, Doofenshmirtz's Cork with a Jellybean taped to it may have been what TV Tropes calls a Xanatos Gambit. Where the villain prepares for the hero's inevitable success, and prepares to turn it on them. He supports this with the quote, "I told you it was a layered idea." But Doofenshmirtz might have simply taken note of Perry's misfortune.
This is the second episode where Doofenshmirtz's invention targets the Moon ("Oil on Candace").
This is also the second time that Doofenshmirtz says Dummkopf!; the first was in "Finding Mary McGuffin". "Dummkopf" is a common German insult that literally translates to "stupid head".
In the song "Me, Myself and I", if seen closely, Romantic Candace gets a balloon from the balloon man, who was also seen in "Phineas and Ferb: Summer Belongs to You!".
This is the first time in production order and the second time in release order Jeremy tries to kiss Candace (the first time was "Phineas and Ferb: Summer Belongs to You!"), but Busting Candace grabs her away.
This is the only episode where Phineas and Ferb consider getting rid of their invention themselves if Perry doesn't destroy it.
This is the first episode when Linda and Lawrence's bedroom appears.
This is the fourth episode which Doofenshmirtz succeeds in his scheme (to make everyone look away as he attempts to make a high-dive). ("Hail Doofania!", "At the Car Wash", "Robot Rodeo")
This is the second time that Dr. Doofenshmirtz both curses and thanks Perry. ("Gaming the System")
This is the second episode in which the Big Idea disappears by going into Perry's lair. The first time this occurred was in "No More Bunny Business".
It is revealed that half of Major Monogram wants to sing.
Candace is complaining about her pictures while she was talking, but now she has one with her and Jeremy talking too. ("The Bully Code")
This is the first and only episode where the boys are sick.
Phineas, Ferb, Isabella, Buford, and Baljeet are the second set of people to get sick. The first set of people are Candace and Stacy ("Put That Putter Away").
This is the first time Ferb calls Linda "Mom" in the series.
This is one of the few episodes where Candace doesn't try to bust Phineas and Ferb.
Vanessa's school appears, marking the fourth time a school has been shown. The first time is Phineas and Ferb's school ("Are You My Mummy?"), the second is Candace and Stacy's elementary school ("Nerds of a Feather") and the third is a lab in Buford's school ("Voyage to the Bottom of Buford").
Ferb is shown to have a World Champion award for video games.
Phineas, Ferb, and their friends unknowingly help Perry fight Doofenshmirtz. Excluding his second dimension counterpart, this makes it the only time they directly fight him.
In the background, when the punk mentions the Caribou Lodge, Charlene (or someone who looks similar to her) is seen behind the girl with pink hair.
The big-lipped girl appears again as one of the teenagers at the dump ("The Lemonade Stand").
This is the third episode that uses the gag of someone mistaking a literal statement for a metaphor. ("Comet Kermillian", "She's the Mayor").
Whenever Doofenshmirtz is singing about a platypus controlling him, he is referencing Perry the Platypus, so when a kid mentions his teacher being a panda, it could be referencing Peter the Panda, a fellow agent ("It's About Time!").
This is the first episode where Linda's parents and Lawrence's parents appear at the same time.
This is also the first time that Phineas and Ferb repeat a project.
This is also the first episode where Doofenshmirtz invents the same inator and repeats his scheme which was previously done before.
This episode is tied with Phineas and Ferb the Movie: Across the 2nd Dimension for the episode with the most songs, as they both have a total of nine songs (although if jingles and shorter songs are counted, the movie would have more).
This is the second "2 Part" episode to feature the most songs during the first half, from "Hey Ferb" to "Back in Gimmelshtump", a total of seven songs. It also features two songs playing directly after each other, "Mom Look" plays just before quickly switching to "Aren't You a Little Young?" 8 seconds later. There are 9 seconds between "You're Goin' Down" and "What'cha Doin'?"?.
Linda is correct when she says that "moose" is the plural of "moose". "Meese" plays off the joke that since the plural of goose is geese, the plural of moose should be meese.
Buford calls the two boys with the fliers "extras".
Doofenshmirtz acknowledges the cut to black at the end of the first act.
Major Monogram's song is cut off the 2nd time (he's cut off by the next video clip) and 3rd time (he's cut off by the end credits).
Doofenshmirtz knows three deja vu moments, which previously were all happened before. First which exactly that the tin foil which would hit the building, second when their attempt to separate the magnet would've been pointless, and third when Perry jumps out to the helicopter and the tin foil hitting the building.
When Kenny Ortega interrupts during Carpe Diem, Phineas says, "Ladies and gentlemen..." when there was really no audience.
At the beginning of Carpe Diem, Phineas said "Well we hope you all enjoyed the show".
When Isabella says that Ferb is still a man of few words, Phineas states that earlier Ferb had two lines.
When Isabella sings What'cha Doin?, she asks if she can be in the show.
Two cameramen appear in the last shot before the credits.
Stacy's name is mentioned three times: Once each by Candace, Phineas, and Isabella. Isabella also says Jenny's name for the first time.
During the song You're Going Down, when Candace is being the teacher, the chalkboard says, "I will not build cold fusion reactors."
As Candace is talking to Stacy on the phone as the boys begin construction on their roller coaster, Stacy and Jenny appear to be getting dressed for their appearance during You're Going Down, meaning they somehow knew it was meant to be a musical, also proven by Isabella saying she was "next" after Candace and her friends leave the backyard.
For the entire "Rollercoaster" song, Phineas is smiling and does not focus on the screaming. However, he is not smiling when he sings his Spanish line.
Right after the song "Rollercoaster", Doofenshmirtz talks about the economic downturn, and is stuck holding a house. During the same song, he talked about buying a bunch of houses then selling them at a higher price during the housing market boom.
During the song "Mom Look", Linda appears to be bouncing to the beat.
During "Back in Gimmelshtump", Balloony appears in the background in one scene.
During the song "Rollercoaster", Isabella and Ginger took the most prominent appearance, making the passengers mostly focused on besides Phineas and Ferb.
Ferb reads the same book he read in "Rollercoaster" and the same one Charlene read in "Finding Mary McGuffin".
The Santa that appears is the one seen in "I, Brobot", not the one seen in "Phineas and Ferb Christmas Vacation!. Despite of this, he is seen with the reindeer and elves (Blay'n and Clewn't) from "Phineas and Ferb Christmas Vacation!".
Ferb is called a man of few words a third time, the first was in the original "Rollercoaster" episode, and the second time by Grandpa Clyde in "Get That Bigfoot Outa My Face!".
Despite this episode being an adaptation of the boy's first project of the series, many characters who did not appear in this episode originally appear during or between songs (Stacy, Jenny, Coltrane, Jeremy, Lawrence, Vanessa, Charlene, Carl, Irving, Buford, Baljeet, the Fireside Girls (except Ginger and Katie), Norm, Good Future and Bad Future Candace, and Dr. Gevaarlijk).
Before unveiling the rollercoaster, Phineas says, "Mark your calenders 'cause you're gonna want to tell your grandchildren about the time you rode the coolest... coaster... Ever!" As seen in the Original Pitch, this line was originally going to be in "Rollercoaster" but was removed.
Carl and Major Monogram both break the fourth wall when Carl replied to Major Monogram that it's a cartoon (since Phineas and Ferb is a cartoon), and Major Monogram scolds Carl about breaking the fourth wall. Also, this is the first time the fourth wall was mentioned in the series.
The dress that Princess Baldegunde and Candace find appears to be the same dress in "Mom's Birthday".
This is the second time Candace sees the Doofenshmirtz Evil Inc. blimp remove one of her brothers' creations. She misses it before in "Suddenly Suzy" and observes it in "The Fast and the Phineas" when it hits the broadcasting tower over the racetrack.
The crowd that gathers in front of city hall as Jeremy and the Incidentals are playing is made up of the same dozen or so people copied over and over again.
This is the first time Perry's entrance brings him directly into Doofenshmirtz's house.
This is the first time Doofenshmirtz hears about his recent activity from Monogram as he is relaying Perry his mission while in his house.
This is the third time in production order ("Journey to the Center of Candace", "Phineas and Ferb Musical Cliptastic Countdown") and the fourth time in release order ("Journey to the Center of Candace", "Phineas and Ferb Musical Cliptastic Countdown", "Phineas and Ferb: Summer Belongs to You!") that Doofenshmirtz interacts with Major Monogram.
Sara appears for the first time in production order and the second time in release order ("Phineas and Ferb: Summer Belongs to You!").
This is one of the few episodes where Doofenshmirtz does his schemes at night.
