Phineas and Ferb the Movie: Across the 2nd Dimension

Behold, the mind blowing first images from beyond our dimensional reality!

When Phineas, Ferb, and Perry follow Dr. Doofenshmirtz through his "Otherdimensionator", they find themselves in an alternate universe where a second, truly evil Dr. Doof rules over his Tristate Area with an army of iron-fisted robots. To save his friends from certain doom, Perry makes the ultimate sacrifice by revealing his secret identity as Agent P. Phineas and Ferb escape, meet their 2nd dimension selves, and begin their own mission to rescue Perry.

As they uncover his plot to travel back to their dimension to take over their Tri-State Area, the gang, as well as their alter-egos, must band together to stop him.

So begins an epic battle as our heroes try to save their home from the clutches of Alt. Dr. Doof... and his sidekick Platyborg! Will Evil Doof succeed and achieve dual world domination? Will Candace finally bust her brothers? Find out in this action-packed, epic adventure - so huge that it crosses over time and space.

Act I
The movie starts with Phineas, Ferb, Perry, Candace, and Dr. Doofenshmirtz, who have been captured by the 2nd Dimension Doofenshmirtz, about to be fed to a Goozim. Phineas compares their current situation to how the day began, and states that everything started out so well that morning.

The scene switches to the beginning of the day, with Phineas and Ferb waking up due to Perry's chattering. The trio do various activities (such as get dressed, brush their teeth), while singing "Everything's Better with Perry", a song about how everything is better with their pet. Afterward, they fall down the stairs next to their parents, and reminisce about when they adopted him from the Organization Without a Cool Acronym's animal shelter. Subsequently, they play baseball, launching the balls off of Perry's tail. They then decide to play platypus badminton using two giant platypus-shaped catapults, which are able to launch objects off their tails like real platypi.

With the help of their friends Isabella, Buford and Baljeet, they construct them, launch themselves off of the tail of the platypult in a large shuttlecock, and fly through the air. Perry, who has assumed his secret agent role as Agent P, has returned from a mission briefing with Major Monogram and Carl; the latter who has given him several new gadgets. While riding in his new rocket car, Agent P collides with Phineas and Ferb’s shuttlecock that changes its course and crashes on the roof of the Doofenshmirtz Evil Incorporated headquarters, destroying Dr. Doofenshmirtz’s latest invention, the Other Dimension-inator.

Meanwhile, after learning that her boyfriend, Jeremy, is looking for colleges, Candace decides to grow up and act more like an adult. She and her friend Stacy go to the backyard to bust the boys, since, now that Candace is an “adult”, she can bust the boys herself. However, she finds that her brothers and the platy-pult are gone, with only Isabella and Baljeet remaining. Candace concludes that the "Mysterious Force", the force that she believes takes away Phineas and Ferb’s invention before her mother can see them, recognizes Candace as an adult, and so kept her from seeing the boys' invention as well. She and the rest of the group go to the park to look for the boys.

Feeling sorry for him, and not knowing that he is evil, Phineas and Ferb help Dr. Doofenshmirtz rebuild his Other Dimension-inator, much to the horror of Perry, who must pretend to be a mindless pet in the vicinity of his owners lest they find out his secret. He tries to stop them by taking away Phineas's wrench and peeing on Doofenshmirtz's couch, but to no avail.

They successfully open a portal to the 2nd Dimension and step through it. They find that that the Tri-State Area in this dimension has been taken over by the 2nd Dimension Doofenshmirtz, who has a scar that goes over his eyepatch. Dr. Doofenshmirtz is redirected by the 2nd Dimension Monogram to a ride that takes him straight to Doofenshmirtz-2. There, they meet, and perform a duet.

Phineas, Ferb, and Perry follow, and Doofenshmirtz-2 recognizes their pet as Perry the Platypus, while the regular Doofenshmirtz doesn’t. Doofenshmirtz-2 sends his minion, General Platyborg, the 2nd Dimension Perry who was defeated and turned into an evil cyborg by Doofenshmirtz-2 a long time ago, to attack Perry, hoping that it will cause Perry to reveal that he is a secret agent. However, Perry remains in his mindless guise even after being hit. Doofenshmirtz-2 then tells Platyborg to hit the boys, to which Perry punches the Platyborg away and reveals his identity.

Phineas and Ferb are surprised at this, and hurt that Perry didn't tell them that he was an agent (primarily Phineas, who yells at him). Doofenshmirtz-2 summons his Norm Bots to seize the trio. The three fall through a window, but Agent P releases his parachute. They land on top of another building, where Agent P does combat against Platyborg with his feet stuck in a skull from an animal skeleton from Doofenshmirtz-2’s lair. Phineas and Ferb trap Platyborg in Agent P’s parachute.

Phineas begins to express his anger again until he realizes that Perry is caught in the parachute. Phineas and Ferb try to pull him back up, but fall; fortunately they all end up being "saved by unconventional architecture". A Norm Bot approaches them as well as Platyborg, but the Norm Bot is hit by the skull and Platyborg is hit by a bus. Phineas, Ferb and Perry are then able to escape.

Act II
Back in Danville, Candace, Stacy, Isabella, and Baljeet have found Buford in the park chewing Victory Gum, as he had won the platypus badminton game they were playing earlier, even though it was more of a forfeited win since Phineas and Ferb had gone missing. Candace and Stacy decides to go back to the Flynn-Fletcher backyard to while Isabella, Baljeet and Buford stayed in the park.

In the 2nd Dimension, Phineas express his anger again about Perry being a secret agent while Ferb reminds him to try to use a remote version of the Other Dimension-inator to get home, but it just opens a portal to another dimension they don’t know. Doofenshmirtz-2 tells Doofenshmirtz that’s what had caused him to go more evil than him and takes over the 2nd Dimension Tri-State Area that he had lost his toy train when he was a child, and Doofenshmirtz can't believe that was his scaring back-story while he had so much scaring back-story than him. As well, Phineas is trying to get over the fact Perry is a secret agent and wonders if Perry is family. Ferb assuages him, and the boys decide they need find their 2nd Dimension selves, who have never heard of summer before. Agent P, upon seeing a news report on TV saying that he should turn himself in to Doofenshmirtz-2 or else Doofenshmirtz-2 will hurt his friends, begins to leave, but is stopped by Phineas and Ferb.

Phineas disowns Perry, telling him to go ahead and go, as he can’t trust Perry anymore, and Agent P leaves. Afterward, they attempt to go across the street to Isabella’s house, but are stopped by a lone Norm Bot, who is taken down by the 2nd Dimension Buford. It is revealed that Buford-2 was part of the The Resistance against Doofenshmirtz-2, but became so good at it that he started resisting the Resistance too. The five fall down a chute once entering Isabella’s yard, and end up being tied by the Firestorm Girls, the 2nd Dimension versions of the Fireside Girls. They are interrogated by the 2nd Dimension Isabella, to which Phineas replies that they are Candace’s brothers. They are untied and led to 2nd Dimension Baljeet, who prefers to be called “Dr. Baljeet.” He explains that the 1st Dimension and the 2nd Dimension are right next to each other, but to get to the 1st Dimension, they would need a lot of energy or having go around clockwise but its unknown to how many dimension to go through. They were later introduce to the leader of the Resistance, 2nd Dimension Candace, shows up, and commands everyone to begin work to divert energy to bring Phineas and Ferb back to their dimension.

Meanwhile, Doofenshmirtz-2 has decided to go the 1st Dimension’s Tri-State Area to conquer there. He gets regular Doofenshmirtz to create another Other Dimension-inator, but it fails to work. It seems that they will need the boys’ help to make it. Dr. Baljeet has been able to open a portal to the 1st Dimension. Upon seeing a news report that Perry has been captured, Phineas and Ferb want to rescue him. Meanwhile, Candace and Stacy are in the Flynn-Fletcher backyard, and Candace tries to talk to the Mysterious Force. The portal from the 2nd Dimension opens up, which the two girls believe is the Mysterious Force. Candace goes through, causing the portal to close, and her being stuck with the 2nd Dimension gang.

Phineas, Ferb, Candace, Candace-2, Buford-2, Isabella-2, along with Phineas-2 and Ferb-2, who have stowed away, go underground in mine carts to attempt to break into Doofenshmirtz-2’s lair to rescue Perry. But they find out that it is a trap, and they are captured.

Act III
Doofenshmirtz-2 taunts Perry that he has captured him and his friends around 3:30 to 4 pm EST that Perry remembers and presses a button on his watch, which opens up a hologram of Major Monogram, who, at that moment, is in the shower. The Doofenshmirtzes, Platyborg and the Norm Bots look away in disgust, and the kids are able to escape. The group tries to race away in the mine carts as the Norm Bots pursue them. To save her and her brothers, Candace-2 separates the mine carts, and she and the rest of the Resistance are able to escape, while Phineas, Ferb, Candace, and Agent P are captured.

Back in Danville, Stacy builds a shrine to the Mysterious Force as an apology for not believing in it, in hopes that it will bring her friends back. Meanwhile, Phineas and Ferb refuse to fix the Other Dimension-inator, but Doofenshmirtz remembers the boys removed his self-destruct button, repairing the device. Now obsolete, Doofenshmirtz-2 sentences the four to doom, as well as regular Doofenshmirtz, as he had gotten on Doofenshmirtz-2’s nerves. The group, in chains, is led to a caged Goozim surrounded by lava. Perry is able to get keys to unchain the gang, but the Goozim’s movements toss them around, and the keys drop near the lava that takes up the ground. As the gang nearly dangles near the magma (thanks to Doofenshmirtz's poor climbing skills), Candace is able to catch the keys. Suddenly, Candace-2 shows up with the Other Dimension-inator remote. She defeats the surrounding Norm Bots, and throws it to Phineas. When he realizes what it is, he tells Perry to let go of the Goozim's cage, but he hesitates. Phineas pleads with Perry to trust him, and he lets go of the cage, just as Phineas opens a portal to another dimension. The group falls through a portal to a flower dimension, and they use the keys to unchain themselves.

The portal is still open, however, so the Norm Bots come through it, so Phineas closes the portal. Candace-2 is captured, and Doofenshmirtz-2, though enraged, goes on with the invasion of the 1st Dimension Tri-State Area. The group goes through numerous dimensions with the Norm Bots in pursuit.

Act IV
As Buford, Baljeet and Isabella are talking in the park, Phineas, Ferb, Candace, Perry and Doofenshmirtz manage to get back in the 1st Dimension. At the same time, however, Doofenshmirtz-2 arrives on Doofenshmirtz Evil Incorporated, retracts the roof as the Other Dimension-inator rises up and activates a portal, allowing millions of Norm-Bots to invade Danville. Candace-2 who has been imprisoned, is rescued by the 2nd Dimension Jeremy, and Phineas-2 and Ferb-2, who have taken on new clothing. After hugging her brothers, Candace tells the 3 of them to go with her to help stop Doofenshmirtz-2 from taking over the 1st Dimension, and they all leave.

Agent P is told by Major Monogram to assist the other agents in fighting the invading robots, while Phineas, Ferb, and Candace are simply told to go home. There, Perry’s locket, which Phineas has, beeps, leading them to Agent P’s lair. They receive a message, activated by the locket, saying that, in desperate times such as these, Agent P needs their help, and that he knows they can help him because of their Big Ideas. Many of Phineas and Ferb’s inventions from past episodes of the series are recreated, and the kids from Danville take control of them, managing to save the agents, who were surrounded by the Norm Bots, and go to war with the Norm Bots. In the heat of battle, Phineas and Perry get to the top of Doofenshmirtz Evil Incorporated building, where they find Doofenshmirtz-2 sending off more of his robots. Perry fights Platyborg, while Phineas goes head-to-head with Doofenshmirtz-2, after he is caught trying to disable the portal.

Perry is eventually able to defeat Platyborg, who, with a chicken stuck on his head and corn in his hands, gets his tail stuck in an electrical socket and is electrocuted. Phineas realizes the dish is what controls the robots, so he goes for the baseball launcher, which Doofenshmirtz-2 grabs and is subsequently cornered by Doofenshmirtz-2, who aims at him with the baseball launcher. Perry hands Phineas a baseball bat, which he uses to hit the baseball that Doofenshmirtz-2 shoots at him from the launcher. The baseball hits the satellite which controls the Norm Bots, and they all fall to the ground, deactivated. Ferb, who has been climbing up the side of the building with plungers, reaches his brother and pet. An enraged Doofenshmirtz-2 emerges from the ground in the cockpit (sleeve) of a a giant robot version of himself and goes to smash Phineas, Ferb, and Perry.

At that moment, Doofenshmirtz, who left his keys in the 2nd Dimension and has been trying to get his neighbor Mrs. Thompson to let him into the building, shows up, and unveils his toy train from his childhood, Choo-Choo. Once he sees his lost train, Doofenshmirtz-2 climbs down the robot, and embraces the toy.

Meanwhile, Candace, who has given up on becoming an adult, goes to the movie theater, where her parents Linda and Lawrence, have been. She tries to get her mom to go outside with her to see the grand battle that is going on in hopes that the mysterious force will make it disappear. Doofenshmirtz-2, who has now become less evil, apologizes for his wrong-doings, and reveals that he has had Self-Destruct buttons on his Norm Bots after all. He presses a button on a remote, and all the robots in the Tri-State Area blow up and disappear. Candace and Linda get outside, and find that all the robots have vanished, and that Candace has failed at busting her brothers – again, something she takes pride in.

Doofenshmirtz-2 returns to the 2nd Dimension, where he is arrested by Monogram-2 and the Firestorm Girls. The Resistance enters Danville, and thanks Phineas, Ferb, and Candace for all they’ve done. The Platyborg has had the evil “fried” out of him, and Phineas-2 and Ferb-2 rush to hug him, happy that their pet has returned. After the 2nd Dimension characters leave, Monogram and Carl show up, and tell Phineas and Ferb that Perry has to go away forever due to his secret being blown. The boys ask if there’s something else they can do to keep their pet, and Monogram and Carl remember that Doofenshmirtz built an Amnesia-inator, and that everyone agreed to have their memory of that whole day (including learning Perry’s identity as Agent P) so they can keep him.



Back at the O.W.C.A.’s headquarters, Phineas, Ferb, Candace, Jeremy, Buford, Isabella, Baljeet and others are lined up (Doofenshmirtz tied up for some reason) to get their memories erased. The brothers say their last good-byes to Agent P. As everyone was ready to get their erased, Isabella asked Monogram that no one will remember anything and he confirms it that she kisses Phineas. Phineas was surprised and seemingly somewhat pleased at this, Isabella tells Carl fires the Amnesia-inator but Phineas tries to stop Carl but to no avail.

Later, Agent P enters his lair, and plugs his camera into the screen, and watches photos taken of he and his owners during their adventure. He smiles, saves the pictures, and then the movie ends.

Reviews
The movie's initial reviews are generally positive. Matt Blum of the Wired.com website claims that "this is truly an instant classic, right up there with some of the best cartoons ever made". Los Angeles Times Television Critic Robert Lloyd enjoyed Phineas and Ferb: Across the 2nd Dimension as well, noting "a hint of emotional depth, regarding the love between animals and the people who live with them". Cartoonclack praised that the TV movie based on a kid’s cartoon can be smart, entertaining, and, dare I say it … moving. Bigshinyrobot states that the movie was really enjoyable that the songs are catchy (especially the opening number about Perry), and the dialogue is witty. Some things may go over children’s heads, such as references to a Georgia O’Keefe and existentialists such as Kierkegaard, Sartre and Nietzsche, but this makes it a movie that any age will love.

Errors

 * When Ferb was falling off the building the skull that had a horn and antler that Phineas and Perry were falling with Ferb. Ferb was on the side with the antler and when Perry deploys his parachute Ferb was holding the side with the horn.
 * In "Everything's Better with Perry" at one point, Phineas' hair was green, but on the release of the movie it was fixed back to red.
 * On a screenshot where Phineas and Ferb (both 1st and 2nd Dimensions), and Buford of the 2nd dimension are released by the Firestorm Girls, it appears that Buford has a strange eye-bug on his right eye.
 * In the flashback of when younger Phineas and Ferb adopted Perry, partial parts of Candace's shoulders were seen through the lower part of her hair.
 * 2nd Dimension Jeremy's gloves disappeared on the part where the lock on the door of 2nd Dimension Candace's cell was burned off. Although, it reappears when he salutes to 2nd Dimension Candace.
 * Perry the Platyborg's limbs armor frequently change throughout the film. At his first appearance, both his hands are made of metal. Later on, his left hand is not made of metal anymore. Near the end, when the evil is "fried" out of him, both hands are not made of metal anymore and what is left to be metal are just parts of his arms.
 * In some promotional shots of the 2nd dimension Phineas and Ferb, they had their 1st dimension counterparts' apricot skin instead of their usual grey skin, but this was fixed before the movie premiere.
 * When Phineas, Ferb and Agent P were falling down the DEI building with a skull, Agent P placed his feet into the eyes of the skull. The skull was pointing down, but when Agent P deployed his parachute, the skull was pointing up.
 * In Kick It Up A Notch, when Phineas' spike bracelet disappears through the song on his left arm.
 * When Ferb went up in the air by the platypult, his shirt button is missing.
 * When Phineas was angry at Perry, the skull was red. When Perry opens the window, the skull was in a proper color it should be.
 * This could be due to the color of the lighting in the room.
 * When Baljeet is flying in The Beak suit, the rocket boosters are seen, but nothing is coming out of them, meaning flight should be impossible.
 * In the beginning, when Perry pees on the couch, it is the middle cushion he pees on, and 1st Dimension Doofenshmirtz flipped it upside-down. Later, when Phineas throws the peed-on cushion at 2nd Dimension Doofenshmirtz, he throws the cushion on the left of the couch and it's the side which Doofenshmirtz flipped.
 * During the song Summer (Where Do We Begin?), when Phineas sings "Summer, bicycles and roller skates" he is seen in a close up with a blue helmet, but in the next shot the helmet is red.
 * When the kids of Danville get ready for battle in Phineas and Ferb's recreated inventions, the sleigh, their "flying" beds from Phineas and Ferb Christmas Vacation! is seen, even though that episode chronologically takes place after the summer of the series which the movie is set in. (It might be that the series takes place over multiple summers or that this episode happens before the others.)
 * After the final battle, when the characters are getting their memories wiped, only Phineas, Ferb, Candace, Doofenshmirtz, Isabella, Buford, Baljeet, Stacy, Jeremy, and the Fireside Girls are shown. Other characters who are shown in the Robot Riot scene but not getting their memories wiped include Irving, Albert, Django, Love Handel, Jenny and other kids (although their memories could have been wiped later or that those whose memories were wiped only include those who knew of Perry's secret).
 * In "Oh, There You Are, Perry", in a flashback, Phineas looked younger when he had Perry, in the movie however, he looked a little older.
 * At one point in "Summer (Where Do We Begin)", Ferb 2's shirt button flickers gray.
 * On the way to Doofenshmitz's-2 building in the tunnels, there are four mine carts, but on the way back, there are three.
 * After Phineas throws the cushion at Alt. Doofenshmirtz, the cushion can be seen back on the couch in a later scene.
 * Near the end, both Perry and Alt. Perry salute with their left paw. This is a common error on TV.
 * Though Olivia Olson (Vanessa Doofenshmirtz) sings the song I Walk Away (when Perry is leaving to surrender to Doofenshmirtz-2), Vanessa herself does not appear at all in the movie, yet is listed in the credits as having appeared. Her scenes are restored in the "Deleted scenes" section of the DVD, in both her current ("Doof's Lair") and alternate ("Vanessa Meets Doof") incarnations.

 * Shortly before "Robot Riot" starts, Adyson and Milly from the 2nd dimension and the Frozen Yogurt machine can be seen in one of the chariots. After all of Phineas and Ferb's inventions are gathered, the same chariot with the Frozen Yogurt Machine can be seen in the background, but Adyson and Milly from the 1st Dimension are aboard.
 * Strangely, during "Robot Riot" the 1st Dimension Adyson suddenly rides one of the scrubbers.
 * Although Jeremy was touring a college with his father that day, he appears at the end of the day to have his memory wiped. (Nevertheless, this error has been resolved since he has been seen with Candace, Baljeet, Ferb, Isabella and Buford as Phineas has been telling them how 2nd dimension Candace took down Norm bots. It is possible that he was told of Perry's secret because of having Perry communicating with Major Monogram without hiding his cover from them, which includes Jeremy, while Phineas was talking. Hence, the brain wiping was necessary.
 * When Perry whistled to alert Phineas he was going to "tail-slap" the baseball bat it had a taped grip. When Phineas catches it however, it does not.
 * Major Monogram says they have no way of erasing memories, forcing them to use Doofenshmirtz's Amnesia-inator, but in "I Was a Middle Aged Robot" the agency had a memory eraser, although it can only be used for one person, so to save time, they just used the Amnesia-inator.
 * Despite having his eyeball in a pouch, Alt.Doofenshmirtz's eye-patch takes the shape of his eye, although his eye-patch might just have been a costume (or part of it), then he got the scar, which resulted in his eyeball falling out/being removed and sealed in the pouch.
 * When Phineas was mad at Perry in the far shots the skull was to his left. When Perry pushes it to open the window, it appears to be directly behind him.
 * In one scene, Buford is seen in the Platadroid Posterior and the giant bowling ball at the same time.
 * At the end, when Phineas-2 reunites with Perry the Platyborg, he correctly points out that the evil was been fried out of him, despite the fact that he had no way of knowing that the 2nd dimension Perry's evil had been had been fried in his fight with Agent P.
 * After hitting Agent P's football helmet during Perry the Platyborg and Agent P's fight, Perry the Platyborg's right metal hand is gone to show a blue paw, though throughout the movie it was always metal. It was possible that it broke off, though.
 * During the deleted Scene "Memory Wipe", the Fireside Girls are suddenly dressed as their 2nd dimension counterparts.
 * When the Norm-Bot who was hit by the skeleton head fell behind Platyborg, he was the proper color, but when the Norm-Bot said he was a painting, parts of his armor was reddish-brown.
 * Near the end, Linda says that she is almost out of popcorn, but it is actually nearly full.
 * When Major Monogram tells the boys they know too much near the end, a part of Carl's glasses are pink.
 * When the Platyborg extends his retractable wings, his retractable wing's shadow wasn't showing when he extended it to get Phineas, Ferb and Perry while swooping down the DEI.
 * When Perry is leaving to surrender himself the door is to his left but Phineas points and Perry leaves to the right but when he exits the house the door is again on his left.

 * When Phineas was about to ring the doorbell of their house in the second dimension, Perry's eyes went from brown, to blue, then back to brown.
 * After Candace and Stacy crash their tree house robots, before they prepare to run, Candace seems to have a missing right leg.
 * After Stacy and Candace come out the tree house robots that are destroyed, Candace's shoes strangely become sneakers.
 * In the Robot Riot sequence, while Baljeet slaps his way against the Norm-bots, parts of the cell-shading of The Beak Suit's neck was seen in front of his headgear.
 * In one point at one of the deleted scenes in "Robot Riot", Gretchen 2 is smashing the Normbots even if she is supposed to be back at the 2nd dimension. She could, however, may have got into the 1st dimension earlier.
 * When Phineas, Ferb, Candace, Agent P, and Dr. Doofenshmirtz are falling into the portal and escape Goozim, for a brief second the camera cuts to Alternate Doofenshmirtz, with his right eye showing and his eyepatch to the side.
 * When Ferb gets the baseball back after Phineas hits it a section of Perry's arm is orange.
 * When Candace and Stacy get out of their tree house robots, Candace's robot is orange instead of pink.
 * In "Brand New Reality", before the baby alien is about to eat the Normbots, some parts of the robots are blue.
 * After Candace and Stacy went out of their crushed robots, Stacy's hair was cut quickly when she got up.
 * In the deleted scene "Inventions Revealed" when Phineas says "Somehow, Perry has replicated all of our inventions" his mouth dosen't move.
 * When Phineas-2 was saying if he can hold Perry a little longer, his neck was transparent.
 * In "Summer (Where Do We Begin?)", when Phineas 2 is seen shivering, Ferb 2's button is missing.
 * After Phineas-2 told Candace-2 how they felt when their Perry disappeared, There is a close-up on Candace-2 and she had a short sleeve on her right arm.
 * When Perry is about to import the photos, he lifts up his hat and retrieves his camera from a hole or depression in his skull that is not normally there.
 * In "Everything's Better with Perry", when they said, "Breathing in and out," Phineas' shoes' sole is color blue instead of white.
 * When Carl shows Perry the watch, behind Perry is a platypus suit. It's color is blue and it only has one glove. But when the hologram of Major Monogram points to the real one, the suit's chest color is white and it has a belt. And when Carl tells Perry the watch also gives and incredible ice cream headache, the suit now has two gloves.
 * During "Robot Riot", if you compare the extended version and the one that's not, the treehouses impact in different times: in the normal, they collide while Phineas was still battling. But in the extended they impact when Phineas and Perry where in Doofenshmirtz Evil Incorporated.

This may instead be a general practice to refer to all superior officers by a single title regardless of gender.
