The Great Indoors

Uh, a picnic in a dangerous unauthorized in a highly bust worthy biosphere? Sounds great!

Bad weather spoils Isabella's plan to earn a Fireside Girl patch, so Phineas and Ferb build a huge biodome to help her. Meanwhile, Candace works herself into a frenzy when she decides that she needs to find out what Jeremy likes about her. Over at Evil Inc., Dr. Doofenshmirtz is trying to rain out a big soccer game, just so he can watch his favorite Mexican soap opera.

Episode Summary
Phineas and Ferb are playing with paper doll version of themselves inside their living room due to the rain outside. Isabella and the Fireside Girls soon come in looking sad, disappointed. They had wanted to get their desert tracking patch but had to cancel because of the rain. Phineas and Ferb immediately decide to help out. Meanwhile, Candace really wants to know what her new boyfriend Jeremy likes about her by so she can make sure she continues to do it to make Jeremy to continue to like her. Linda sarcastically remarks that maybe he just likes to hear her talk, and on her way out the door wonders where Perry is.

Perry the Platypus has walked to the backyard where he pulls on a branch to open his secret compartment. Unfortunately, due to the rain, it has flooded and he gets drenched. As he comes down the tube, he slips on his chair—flinging himself into the screen and falling on his face. Major Monogram and Carl think this is hysterical, and watch it a few times in slow motion again in front of Perry, much to his dismay. Monogram then tells Agent P that they think Doofenshmirtz is probably behind the large amount of rain, so Agent P is ordered to stop him at all costs—or preferably at a reasonable cost.

Back in the Backyard, Phineas and Ferb have quickly completed the biosphere dome since no one likes working in the rain. Inside they explain how it can simulate almost any environment, and they quickly simulate a large desert. Isabella is very impressed, but after finding a water cooler in a cactus, she tells them not to make it too easy for them.

Jeremy arrives wanting to have a picnic indoors, but once he sees the biosphere he quickly changes his mind to have the picnic in there. Candace is torn because she wants to bust her brothers, but she also needs to spend time with her boyfriend to find out what he likes about her. She decides to resist the urge and try to find out what her boyfriend likes most about her. Back in the Biosphere, Isabella and the Fireside Girls are well on their way to accomplishing their Desert Tracking Patch, including seeing a mirage and experiencing how to treat Heat Stroke (to which Adyson may have volunteered for). Isabella is still pleasantly annoyed how Phineas and Ferb have pampered them by providing them with everything they need to accomplish the patch.

Perry the Platypus has flown to Doofenshmirtz’s lair and jumps through a window. However, he slips on another chair and falls straight into Doofenshmirtz’s trap: a large clear tube. Doofenshmirtz comments on how he had a much more elaborate trap prepared for him but because he slipped on a chair he wasted a full day’s worth of work—but at least it will look great on the Christmas Gag reel. Doofenshmirtz explains that he’s made a Rain-Inator: An enormous shower head to spray millions of gallons of water into the clouds to make it rain (though he’s pleasantly surprised that no one has noticed it yet).

Back at the Biosphere, Isabella and the group have made it across the desert. They decide to try and get their Rain-forest Navigation Patch, and Ferb transforms the desert into a rain-forest in a few short seconds. Meanwhile, Candace and Jeremy have been having their picnic in the middle of the desert and Candace is still trying to figure out what Jeremy likes most about her. Just as he’s about to answer, their spot turns into a rain-forest. Jeremy is so impressed with the rain-forest that he doesn’t answer Candace’s question, which makes her walk off for a moment to release her pressure. The Fireside Girls are enjoying looking at the rain-forest and Adyson thinks she found a new species of something, but before she can say what it is, she is swept away by a raging river, followed closely by Phineas, Ferb, and Isabella on a log where Isabella also earns her Swift Water Rescue Patch. Jeremy calls Candace back and convinces her to take a raft ride on the river with her on the umbrella they were using before.

At Doofenshmirtz’s, he explains that the reason he caused all this rain was that he had bought a big screen T.V. from 1985 at a garage sale but it was stuck on this crazy Spanish channel and he had grown to love a Spanish soap opera on the channel called "El Matador de Amor" because of the three simultaneous interconnecting story lines. The last episode was a cliff hanger where the hero was about to tell the heroine what he loved about her when it was preempted because of a soccer and he rain out the soccer game since game he hates soccer. So he rained out the game so he could finish watching his show.

In the Biosphere, Candace and Jeremy are floating down the river and to answer Candace’s question about what he likes about her. He sings the song Set the Record Straight. The Fireside Girls have completed their Jungle Navigation Patch, so Ferb makes a mountain so they can do Rock Climbing, and a small rock knocks Adyson on the head. Jeremy and Candace land on the mountain (which has large amounts of snow too) and while Jeremy is enjoying this, Candace is getting very infuriated. When Adyson accidentally knocks a large boulder loose, then continues to fall landing very close to where Candace and Jeremy were sitting. That was the last straw and Candace runs after the boys to bust them, but Jeremy confirms that the rock was made entirely out of paper-maché. The Fireside Girls reach the top of the mountain where they earn their Rock Climbing Patches. Phineas and Ferb then offer them Hang-gliders and they soar off the cliff. Candace tries to get them, but her ledge collapses and she clings to a small ledge off the edge of the cliff.

Doofenshmirtz’s favorite show has finally started and he’s very excited to see how it ends. He doesn’t know that Perry the Platypus has moved his giant tube by a downspout and it is filling up with water so that he can climb out of it. In the biosphere, Jeremy comes to rescue Candace by jumping off the cliff with the umbrella and picking her up on his way down. They float out of the biosphere and into the front lawn where Jeremy exclaims how much he loves that umbrella. Jeremy is just about to tell Candace what he likes most about her when Linda pulls up and Candace rushes to Linda to bust the boys. Again back at Doofenshmirtz’s, the climax is getting very close and Doofenshmirtz is getting very anxious and excited. However, without him knowing, Perry escapes his tube and ties the rain-inator with a passing Jet using his grappling hook. The jet pulls the rain-inator right out and it immediately stops raining. Right when the Hero is about to say why he loves the heroine, the soccer game turns back on.

The Rain-Inator is dangling from the jet, and as it passed over the Flynn-Fletcher house, it hits the biosphere like a golf ball. By the time Linda gets into the backyard, the biosphere is gone and the kids are just standing in the backyard. Doofenshmirtz is in shock because he doesn’t know what could have gone wrong, but he turns around and finally notices that Perry is out of his trap and the Rain-Inator is gone (though a huge stream of water is still coming up). Perry flies away while Doofenshmirtz curses Perry in Spanish and remarks how this will cost a fortune for his water bill. Back home, Linda asks Candace if she ever figured out what Jeremy liked best about her, and Candace quickly runs back to the front yard to finally get the response. Just as Jeremy is about to say what he likes best about Candace, the channel changes to the soccer game as one of the teams score.

Whatcha doin'?

By Isabella:

Perry's entrance to his lair
Perry irritably walks out into the freezing rain toward the big tree. Just as Perry opens a tree elevator, a flood of water splashes out of it, soaking Perry even more. Perry walks into the elevator into a tube toward the lair, quickly slipping off his chair and smacking into the mission screen as he lands. Major Monogram and Carl find it very amusing.

Background Information

 * http://www.toonzone.net/forums/showthread.php?p=3772737
 * This episode was aired on Disney Channel on Demand at February 28, 2011.
 * Linda says "Hey, where's Perry?" instead of Phineas.
 * Doofenshmirtz remarks that "El Matador de Amor" has three simultaneous storylines that interconnect, just as Phineas and Ferb does. Even the plot is similar, with Jeremy trying to tell Candace why he loves her (just like in the Spanish show, the episode is interrupted by soccer just when Jeremy was about to announce the reason he likes about Candace).
 * Dr. Doofenshmirtz said "¡Maldito seas, Perry el ornitorrinco!", the European Spanish version from the phrase "Curse you, Perry the Platypus!".
 * This episode shows that Adyson Sweetwater is accident/danger prone. Also, she hallucinated about salamanders twice.

Production Information

 * This episode was first revealed as an "unnamed bio-dome episode" in the comments of a demo song posted on Soundcloud.
 * This episode along with "Canderemy" were the first episodes aired for Season 3.

International Premieres

 * April 7, 2011 (Disney Channel Brazil and "Latin America")
 * May 1, 2011 (Disney Channel Asia)
 * May 9, 2011 (Disney XD UK)
 * June 1, 2011 (Disney XD Canada)

Errors

 * The first time Major Monogram asks Carl to replay Perry slipping, the button-pushing noise comes before Carl pushes the button.
 * Isabella and Ferb are not seen after the bio-dome is taken away by the plane, even though the others are.
 * When Isabella starts talking in the desert, Adyson is walking, but when she is finished, Adyson is being carried by Katie and Ginger even though it was only six seconds in between. However, some individuals can develop symptoms of heat stroke suddenly and rapidly without warning, so it's possible she simply fainted right then and there.
 * Adyson received a concussion from a rock but Jeremy later revealed they were paper mache. However, it is possible that the mountain is made of both real and paper rocks, or possibly since Adyson was already worse off she succumbed to other ailments more easily.
 * Technically, there is no difference between sunstroke and heatstroke, though that may have been part of the joke.
 * When Major Monogram tells Carl to stop replaying the footage of Perry slipping, Carl's neck is drawn outside of his shirt collar.
 * It isn't seen how Phineas, Ferb and the Fireside Girls got out the biodome without being stuck in it.
 * When Doofenshmirtz is watching the Spanish commercials, the screen reads "Esponja Milagroso!". This is gramatically incorrect because "esponja" is a female noun in the spanish language, and the female of "milagroso" is "milagrosa". Also, a first exclamation sign ("¡") is missing. These errors were corrected in the latin american dub.
 * Later on, a character in the soap opera says "...su malvada hermana gemela ha sido envenenado". The correct phrase is "...ha sido envenenada".

Continuity

 * This episode probably came before "Fireside Girl Jamboree," as Adyson, among others, earned her record 6 patches, setting what would have been at the time the record, before Candace would later beat it by 44.
 * This is the third time it was raining and everyone was forced to stay inside to do the big idea ("The Monster of Phineas-n-Ferbenstein", "Hide and Seek").
 * All the rocks in the mountains are made of paper-maché. ("Suddenly Suzy")
 * Doofensmirtz's invention is somehow not noticed by the public again. ("Split Personality")
 * While Doofenshmirtz is annoyed that Perry didn't fall into his trap the way he planned and Perry is rising up from the trap door, Doofenshmirtz mentions it'll look great on the "Christmas gag reel". This possibly might mean Doofenshmirtz has had a change in opinion about Christmas. However, this would not make sense since the Christmas special is at the end of the summer and had yet to happen according to the timeline. ("Phineas and Ferb Christmas Vacation!")

Allusions

 * The Great Outdoors - Title reference
 * The Little Mermaid - The part of Candace and Jeremy's ride down the river where the raft is enclosed with weeping willows branches that look like hearts along with dancing fishes and turtles resembles the scene during which "Kiss the Girl" is played.
 * Interestingly enough, Ashley Tisdale, who provides Candace's voice, recorded a cover of that tune for the movie's special edition DVD release, in 2006.
 * Doofenshmirtz sings the line Raininator in the style of the musical Singing in the Rain, including similar background music.
 * The biosphere is extremely similar to the golfball-shaped Spaceship Earth, the signature attraction at Walt Disney World's Epcot.
 * Back to the Future - When the gang went down via the hang-gliders, the background music sounded similar to the main theme from the Back to the Future movies. This is the third time this background music was used. ("Phineas and Ferb Get Busted!", "Phineas and Ferb Summer Belongs to You!)"
 * Mary Poppins - Mary Poppins floats on the wind with an umbrella in the books and movie, just as Candace and Jeremy do in this episode.
 * The line "Can we cook, or can't we?" upon seeing the entire outdoor world created inside an enclosed area matches the line "Can I cook, or can't I?" said by Dr. Carol Marcus under similar circumstances to Admiral Kirk in Star Trek II: The Wrath of Khan.
 * America's Funniest Home Videos - Perry slipping off his chair is similar to a video in which a man is seen slipping off the deck of his pool into his pool.
