->'''Phineas:''' This is gonna be the [[BestXEver best day ever!]]

''Phineas and Ferb The Movie: Across the 2nd Dimension'' is a MadeForTVMovie based off of Disney's ''WesternAnimation/PhineasAndFerb'', and the fourth Made-for-TV Movie based on an animated DisneyChannel Original Series. It premiered on August 5th, 2011.

When Phineas, Ferb, and Perry follow Dr. Doofenshmirtz through his "Otherdimensionator", they find themselves in an alternate universe where a second, truly evil Doof rules over his Tri-state 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. So begins an epic battle as our heroes try to save their home from the clutches of Evil Dr. Doof and his sidekick Platyborg. Will Evil Doof succeed and achieve dual world domination? Will Candace finally bust her brothers? Hell if we know (though we do know how that [[FailureIsTheOnlyOption last one will turn out]]), but watch it to find out.

A video game adaption was released August 2nd, as well as a soundtrack.

----
!!This TV movie includes examples of:

* ThreeDMovie: Parodied, with the full title: "Phineas and Ferb: Across the 2nd Dimension In Fabulous 2D".
** Mentioned again towards the end of the movie when Doof-2 tells the others that he hopes they have their glasses on.
** Lawrence and Linda never see what's happening in Danville due to being engrossed in one of these the whole time.
*** And they were watching a ''RomanticComedy''...
**** It's possible it ''may'' also be a shout-out to TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension
* ActionGirl: The alternate versions of Isabella and the Fireside girls (who are called "Firestorm Girls" according to WordOfGod), more so than their normal counterparts. Candace-2 is more a LadyOfWar. One only needs to see Candace-2's [[CurbStompBattle first encounter with the Norm-bots]] for proof.
** And the First Dimension Candace, Isabella, Stacy, and Fireside Girls all help out in the final battle.
* AdultFear: Doof-2's little dystopian government. Kids are likely not to take things like Linda hiding in the basement and the Norm-bots asking for documents very serious. Towards the end, it gets worse with the whole Boy-borg thing.
* AdultsAreUseless: The members of LaResistance and everyone in the final showdown are all kids (excluding OWCA agents... who are all animals). The adults only seem to be good for getting subjugated, with the alternate universe mom even spending most of the movie hiding in the basement.
** Love Handel actually offered their help, but Phineas relegated them to musical accompaniment -- [[AutobotsRockOut which they enthusiastically provided.]]
*** In fairness though, this is WesternAnimation/PhineasAndFerb. A sequence like that simply wouldn't work ''without'' a musical number, and Love Handel were pretty much the best guys for the job (and Danny does get a robot kill to his name in a deleted scene, with his ''[[OffhandBackhand bare hands]]'', no less).
** Candace's GenreSavvy plan to ensure victory for the heroes does involve adult participation, but that's more "making use of" adults than adults actively being useful.
** Depending on [[{{VagueAge}} how old]] [[{{Cameo}} Albert Du Bois]] (Irvin's older brother) is, he might qualify if he's turned 18 since [[Recap/PhineasAndFerbTheDoofSideOfTheMoon "'The Doof Side of The Moon'"]].
* [[AllThereInTheManual All There In The Licensed Game]]: Y'know that turtle agent that appears during the finale? He's a character made for the game (named Terry, adopted by an alternate Baljeet), [[EnsembleDarkhorse though the creators loved him enough to give him a cameo).]]
* AlternateUniverse: They actually go through a lot of them.
* AmazonChaser: Buford-2's reaction to Candace-2. Which is a stealth reference to another, earlier episode in which Candace wonders how Buford's number got in the contacts list of her cellphone.
* AndShowItToYou: In the extended version of "Robot Riot", the lyrics talk about ripping out the robot's CPU and showing it to them while it's still processing. In a deleted scene, Danny actually does this to a robot that gets too close while he's singing that very line.
* AnimationBump: The character animation during the whole scene with the Goozim is very squash-and-stretch and unusually fluid.
** Also, the entire movie has noticeably better animation than the show, though this was to be expected.
* AnvilOnHead: Subverted. At one point, it looks like a Norm-Bot is about to fall on Platyborg, but it misses. [[DoubleSubversion And then Platyborg gets hit by a bus.]]
** Though played straight moments earlier by the aforementioned Norm-bot, which was hit by a falling animal skull.
* ArsonMurderAndJaywalking: When Perry reveals himself to be a secret agent, Phineas is upset because [[WasItAllALie he thought that Perry was only using them as a cover and never actually cared about or trusted them]], Perry [[WhatTheHellHero could have stopped Phineas and Ferb from helping Doofenshmirtz with his plan, but didn't]], and... Perry could have been cleaning his own litterbox this whole time.
* AsYouKnow: As a reminder to everyone watching, Monogram reminds Perry at the beginning of the movie that if his cover is blown, he would be relocated and Phineas and Ferb would never see him again. [[spoiler:And as expected, it is brought back up at the end.]]
** Of course, Monogram lampshades it. "I don't need to remind you...but I'll do it anyway..."
** Also said word for word by Monogram when telling Perry of the camera used to study and replicate Doof's inventions. [[spoiler:Again, it's brought back when it's shown Perry's been replicating Phineas and Ferb's inventions as well.]]
* AuthorityEqualsAsskicking: Definitely played straight with Candace-2's resistance. Averted with Doof-2's army, except by Platyborg.
* AutobotsRockOut: {{Invoked| Trope}} by Phineas asking Love Handel to provide the music for the epic battle.
* {{Badass}}: ''Good '''grief''''', Candace-2.
* BadassAdorable: Alternate Isabella and the Fireside Girls anyone?
** The Alternate Fireside Girls for sure. Case in-point: when Phineas, Ferb, Buford-2, Phineas-2 and Ferb-2 fall through the hidden trapdoor, the Alternate Fireside Girls drop in on them and tie them up in '''under 5 seconds'''. With little effort no less!
** Plus, their one fluid untieing somehow got the boys into a human pyramid, which then promptly collapsed.
* BadassInDistress: [[spoiler:Candace-2]] becomes one when she gets captured by Doof-2 while saving the first dimension counterparts of [[spoiler:her brothers and their friends.]]
* BareYourMidriff: [[http://images4.wikia.nocookie.net/__cb20111229002403/phineasandferb/images/d/d7/2nd_dimension_candace_small.png Candace-2]]. [[{{Fanservice}} And it looks pretty darn good on her]]. To bottom this off, she also gets a ZettaiRyouiki upgrade.
-->'''Candace:''' Is that me? I look ''good''.
* BeardOfEvil: Doofenshmirtz-2 has one.
* [[PoorCommunicationKills Being Unable To Communicate Kills]]: Phineas probably would have gone a lot easier on Perry had he known that finding out Perry's secret identity also meant never being able to see him again. It ''was'' in the pamphlet Perry gave him, though... which Phineas threw out. Actually, it says something that Phineas forgave him long ''before'' finding out that Perry had a damn good reason to keep it from him.
* BewareMyStingerTail: Perry the Platyborg.
* BewareTheNiceOnes: Phineas could not let it go at first when he [[spoiler:found out a Perry was a Secret Agent.]]
* BigBad: Doof-2.
* BigBadWannabe: Main Universe Doofenshmirtz, even more so than usual. Here, he tries to enter a BigBadDuumvirate with his alternate self, but he was just too incompetent to be of any use.
* BigDamnHeroes: Jeremy-2, and Phineas and Ferb-2 "busting" Candace-2 out.
** Candace-2 rescuing Phineas, Ferb, Candace, Perry, and Doofenshirtz.
** Perry coming to the aid of his fellow agents, closely followed by Phineas rescuing ''him''. Then followed by all of the other kids in [[spoiler:Phineas and Ferb's old inventions]] coming to ''their'' aid.
** At the very, very end, Dr. D, though in a rather unconventional manner.
** Subverted [[spoiler:by Ferb during the final battle. It's set up so that it looks like he's going to pull this for Phineas and Perry, but the main bulk of the fight is done by the time he arrives.]]
*** Similarly, [[spoiler:all the second dimension Resistance members get to do at the end is formally arrest Doof-2]].
** Early on we have Buford-2 saving both dimension Phineases and Ferbs from a Normbot.
* TheBigDamnKiss: [[spoiler:Isabella lays one on Phineas right before the LaserGuidedAmnesia kicks in.]]
* BigDamnMovie: Where to begin?
* BigNo: Doof-2 had it in slow motion when he realized [[spoiler:the Norm-bots would be defeated.]]
* BigSisterInstinct: Candace-2, taking it to the expected "Candace" levels of obsessiveness:
-->'''Candace-2:''' [[CrowningMomentOfHeartwarming I'll do anything to protect the ones I love]].
** Almost to the point of {{Deconstruction}}, seeing as how she was willing to let the alternate versions of her family be captured in order to protect her own. In her defense, though, she did come back for them, once her own brothers had been escorted to safety.
** Perry's BigBrotherInstinct[=/=]PapaWolf tendencies also come into play in the movie.
* BittersweetEnding: [[spoiler:The movie ends with everyone getting the memory of their greatest adventure ever erased from their minds because they found out about Perry's secret identity. It even comes with a [[TearJerker touching moment]] between Phineas and Perry.]]
* [[RedArmbandOfLeadership Black Armband Of Leadership]]: Candace-2.
* BreakingTheFourthWall: During the VillainSong, they specifically mention that Lorenzo Lamas played Meap. Also, in the 3D game based on the movie, when the last level is completed, Doof-2 claims the player will pay for defeating him if they make a sequel.
* BrickJoke: At the beginning of the movie, Perry pees on Doofenshmirtz's couch in a desperate attempt to distract Phineas and Ferb from helping him with his plan. [[spoiler:At the climax of the movie, when Phineas is confronting Doof-2, he chucks the soaked cushion in his face, with Doof-2 disgustedly wondering what's on it.]]
** At the beginning of the movie Phineas and Ferb, after catching popcorn in their mouths, chuck some at Perry hoping he'll do the same. They just bounce right off his head. Perry then catches some popcorn in his mouth at the end of the movie, after [[spoiler:defeating the Platyborg.]]
** The couch pee gets another callback earlier in the movie when Doofenshmirtz suddenly realizes that it was a conscious decision on Perry's part.
** Right after his [[TheReveal reveal]] as a secret agent to the boys, Perry hands Phineas a pamphlet made just for this situation, which Phineas rolls his eyes at and throws away. Later, when Major Monogram explains that Perry must now [[spoiler:go away because of his blown cover, everyone is surprised and confused, to which the Major asks if...they read the pamphlet.]]
-->'''Major:''' Does ''anyone'' read those things?
** Also when Phineas is trying to explain the situation to Candace, and when she fails to comprehend the situation, he says that he wishes that he had never thrown the pamphlet away.
** Buford-2 [[spoiler:eventually gets his nachos.]]
* CallBack: The remote-controlled baseballs are heavily relied upon as weapons - exactly what Candace used them for in "Chronicles of Meap". [[spoiler:For that matter, a lot of Phineas and Ferb's creations are used in the battle. A lot of their inventions were recreated and stored by Perry, just in case a situation as bad as that occurred.]]
** Carl's LatexPerfection disguise from "You Scream, I Scream" makes a return.
** In "Kick It Up a Notch", there's a likely call back to Doofenshmirtz's LeastRhymableWord moment in "Does This Duckbill Make Me Look Fat?", with Doof-2 actually managing to come up with some rhymes for "evil" in his verse.
** Candace's reveal [[spoiler:as the leader of LaResistance]] included a reference to her parsnip allergy, complete with raspy voice.
** Doof-2 checks whether our Doof is really his counterpart by offering him Almond Brittle.
** Poke the Goozim with a stick!
** Monogram is only sweating through his eyes! We're reasonably sure a lost goldfish is not involved, though.
** Doof-1 rattles off a list of his backstories--all from previous episodes--when he finds out that Doof-2 is eviler than him simply because he lost his toy train.
** Doof-2's BeardOfEvil may be a nod to "Crack the Whip!", specifically Doof-1's inability to grow facial hair, in pointing out that Doof-2 shares none of his counterpart's {{Freudian Excuse}}s.
** May overlap with BrickJoke; after Phineas & Ferb watch Candace-2 take out the Norm-Bots Phineas asks Candace "can you do that?"
--->'''Candace:''' Well apparently.
*** Then later Phineas-2 & Ferb-2 watch their normal counterparts use a Norm-Bot arm to destroy the others.
--->'''Phineas-2:''' Can we do that?\\
'''Candace-2:''' [[SubvertedTrope No, keep your heads down]].
** Remember the [[IncrediblyLamePun bonehead Norm-Bot]] with the boney bullhead? Think back to the chariot-race episode, where Norm was introduced. At the end, he got a minotaur helmet on his own head.
** A very small one, but Ferb carrying a handkerchief that he offers to those who need it, first seen in "Summer Belongs to You". Ferb-2 does this as well.
** In the ride between Doof-2's 'indentured executive assistant' and Doof-2 himself, there are reminders of some of Doof-1's [[FreudianExcuse freudian excuses]].
*** A man in an animal costume carrying a birthday cake.
*** Lawn gnomes.
*** Balooney's face.
** In the alternate dimensions montage:
*** One dimension is populated with giant floating baby heads. Apparently, the one that appears in several other episodes comes from there.
*** In another episode, the Monster-Truck-Awayinator sends things to another dimension with an alien baby. The gang passes through it.
*** On a subway train, Candace encounters the talking zebra that keeps calling her "Kevin" from "The Ballad of Badbeard". He is reading a newspaper that has "Kevin Wins Election!" as one of the headlines.
** Towards the end when Phineas is using a bat to [[spoiler:hit the baseball into the dish controlling the Norm bots,]] as we learned in [[ClipShow Phineas' Birthday Clip-O-Rama!]] Phineas bats left-handed.
* TheCameo: Agent T, the orange turtle agent near the end of the movie, technically debuts in the game. The creators liked him so much they gave him a cameo in the movie.
** Irving also makes a brief appearance as [[spoiler: the bottom half of The Beak suit]]. Django can be seen in the final battle as well.
* CelebrityParadox: Parodied when Lorenzo Lamas is mentioned in a song's lyrics, and the *very next lyric* lampshades that [[NoFourthWall he played Meap]].
* ChekhovsArmory: Everything from Perry's wrist communicator to [[spoiler:nearly all of Phineas and Ferb's previous projects]] come into play in this movie.
** Basically the entire first half of the movie sees payoffs in the second half. Have these guys been comparing notes with EdgarWright?
* ChekhovsArmy: [[spoiler:The army of inventions by Phineas and Ferb.]]
* ChekhovsBoomerang: [[spoiler:The ball shooter.]]
* ChekhovsGun: Man, where do we start?
** Perry's reflex when getting his neck scratched, [[spoiler:which his counterpart shares.]]
** Phineas playing baseball with Perry at the beginning of the movie.
** Perry's locket tag.
** The buffet Norm set up at the beginning of the movie.
** The urine-stained couch cushion.
** The Platypult that was towed away near the beginning of the movie.
** Doof-2's Choo-Choo, [[spoiler:and Doof-1 mentioning that he never lost his.]]
** Perry's hat scanner that he was using to analyze all of Doof's creations so the OWCA could recreate and study them [[spoiler:which he turned out to also be doing with Phineas and Ferb's projects.]]
** The time Major Monogram told Perry not to video call him because he would be in the shower [[spoiler:is used to distract the Doofs and allow everyone to escape.]]
** The ball shooter from the Chronicles of Meap [[spoiler:[[RunningGag strikes again]] as an important item. It is used to destroy robots, and also winds up ''destroying the robot army'' because it takes out a transmitter that controls them.]]
*** Heh, "strikes" and "running." IncrediblyLamePun much, anybody?
** The sports equipment that goes flying when Platyborg punches Perry into a cabinet.
** The skull belonging to the weird animal skeleton in Doof-2's office.
* ChekhovsHobby: Phineas and Ferbs hobby of creating inventions, of course.
* ClarkKenting: When Phineas and Ferb told Doof-1 their pet platypus' name was Perry, he simply thought it was [[NamesTheSame another platypus named Perry]]. Seeing Perry stopping Platyborg from attacking Phineas and Ferb wasn't enough to make him connect the dots. Doof-1 still had to see Perry putting on the hat. Doof-2 couldn't believe the clues both Doofs saw weren't enough for Doof-1 without the hat.
** Doof-2 [[LampshadeHanging hangs a lampshade]] on this by forcing Doof-1 to sit and look at pictures of Perry with and without his hat. "A platypus." "''Gasp! '''Perry''''' the Platypus!"
* CloudCuckoolander: The Norm-bots (when in Norm-mode), manage to even outshine the original Norm in terms of this, most like because they have it balanced out with [[TwoFaced their completely serious mode]].
* ConspicuousCG: The Norm-bots.
** Really, it's all over the place. Chances are, if it's big, it was done in CGI.
* ConspiracyPlacement: What else but, "Doofenshmirtz Evil Incorporateeeeeeeeeeeeeeeed!"
** "Doofenschmirtz Evil News Updaaaaaaaaaaaaaaaaaaaate!"
** The "OWCA Animal rescue center" sign.
** The "OWCA HQ" seen at nearly the end of the movie. It's also complete with "Pay no attention to this sign".
* ContinuityPorn: '''UpToEleven'''. Expect to see many references to events in the show. [[spoiler:In the film's climax, almost all of the inventions made by the boys throughout the show are used to fight off Doof-2's army.]]
* ConvectionSchmonvection: The entire sequence [[spoiler:and escape]] where Phineas-1, Ferb-1, Candace-1, Perry the Platypus and Doofenshmirtz-1 are being 'doomed', which is over a pit of lava.
** Possibly subverted by the fact that the scene takes place in an alternate dimension. Convection may very well not exist there.
** It's almost confirmed. When the Norm-bots fall in, they just kind of...sink, instead of melting or bursting into flames.
*** Makes sense considering ''physics'' don't really seem to exist in the first dimension.
* CoolShades: Candace-2 sports these.
* CrazyPrepared: The tow truck driver, who has attachments to tow ''anything''.
** For that matter, [[spoiler:Perry analyzing and storing all of Phineas and Ferb's previous projects just in case they ever needed them in a situation.]]
** Both Doofs' collect coins in case vending machine take over.
*** And Doof-2 has a bowl of rice pudding on hand... just in case an alternate version of himself shows up.
** One of the gadgets presented to Perry, a souped-up harpoon, is only for if he's attacked by the royals or a member of Parliament. Carl even admits he probably won't need it (and he's right; it ends up being the only gadget not used).
* CrouchingMoronHiddenBadass: [[spoiler: Who are the ones in the Beak suit sissy slapping ''dozens of Normbots'' out of the sky? Baljeet and Irving. Irving is implied to have taken out numerous Normbots on his own later in the battle as well.]]
* CurbStompBattle: The heroes easily take out Normbots as long as they are wielding weapons and aren't too heavily outnumbered. It's when Platyborg joins the fight (or if there are simply too many Normbots) that things become a problem.
** [[spoiler:However, even with the advantage of surprise, all of the local O.W.C.A. agents (minus Perry) working together quickly fall to the Normbots.]]
* CutHisHeartOutWithASpoon: "Robot Riot" is half this, half TheReasonYouSuckSpeech, all directed at Doof-2's robot army.
* CutSong: [[http://www.youtube.com/watch?v=UWyTdT0ybag "Mysterious Force".]]
* {{Cyborg}}: Meet Platyborg, the world's first and only cyborg platypus. Though not that second part if Doof-2 had his way.
* DangerouslyGenreSavvy: Doof-2, who even sets up a presentation to explain Perry's ClarkKenting to our Doof.
** Not to mention the scene where Doof-2 orders Perry the Platyborg to attack Perry, who continues to play dumb. Then he orders the Platyborg to attack Phineas and Ferb, knowing [[PapaWolf Perry]] [[BigBrotherInstinct wouldn't let him.]]
* DarkerAndEdgier: Compared to the rest of the series.
** The defining characteristic of everone and everything's Dimension-2 counterpart.
* DarkAndTroubledPast: Humorously subverted with Doof-2, who only became evil because he lost his toy train as a child. Our Doof (who - among other things - was forced to work as a lawn gnome and is TheUnfavorite to his parents) is stunned by this.
* DarkReprise: ''Sort'' of. When Perry the Platyborg is first revealed, a darker, more evil-sounding version of the Perry the Platypus theme can be heard in the background. It's used as Platyborg's {{Leitmotif}} for the rest of the film.
* DeadlyDodging: Perry manages one heck of a display of this when rescuing his fellow agents from the Norm-bots.
** How Phineas finds out about the transmitter Doof-2 uses to control his Norm-bots.
* DidntThinkThisThrough: Doof-2 should've mass produced more robots instead of bringing the ones that were controlling his universe into the other.
** Also, Phineas and Ferb's attempt at rescuing Perry from the two Doofenshmirtzes.
** Then there's when Doofenshmirtz asks Candace to unlock his chains. While he's hanging over lava. She's quick to point out the flaw.
* DisappointedByTheMotive: Doof-2's tragic back story is that he lost a toy train as a child. Immediately lampshaded by Doof who lists off tragic back story after tragic back story.
* DisneyAcidSequence : A brand new reality eventually fades into this. It is a Disney movie after all.
* DontExplainTheJoke: Doof-2 regarding how his HumongousMecha has a trick up his sleeve... himself... [[SelfDemonstratingArticle because the cockpit is in the sleeve]].
* DoomyDoomsOfDoom: Parodied when Doof-2 points to all his prisoners individually while flippantly saying "Doom" over and over again. And when Doof-1 gets a "Doom" from a sock puppet.
** According to Doof-1, apparently that's the ''second'' time that's happened to him.
* TheDragon: Perry the Platyborg.
* EasilyForgiven: [[spoiler:{{Subverted}} with Doofenshmirtz-2 in the end.]]
-->'''Doofenshmirtz-2:''' You know, my crimes against humanity had just completely slipped my mind.
* {{Egopolis}}: The alternate Tri-State Area has pretty much everything named after Doof (Dooferalls, Doofopoly, Doofensday etc). Although there is a building called [[SubvertedTrope Vanessa Plaza]].
* EnemyMine: Doof pretty much has to team up with Perry (and his owners) near the end.
* EpicFail: Doof-1's failed attempt to use a robot army to take over the Tri-State Area. (flashback scene)
** His usual ClarkKenting reached this kind of level.
* EurekaMoment: An unfortunate instance where Phineas accidentally reminds Doof-1 of what he did to get the Other Dimension-inator to work.
** When Candace is reminded of her attempts to bust Phineas and Ferb [[GenreSavvy and goes off to weaponize her]] FailureIsTheOnlyOption.
* EvenEvilHasStandards: Minor, but when Doof-2 orders Platyborg to attack Phineas and Ferb, Doof-1's reaction is a shocked: "What?!"
* EverythingsBetterWithPlatypi: Shown in [[http://www.youtube.com/watch?v=CwEvIwWQ184 Everything's Better With Perry]].
** While Everything's Worse With Platyborgs [[spoiler: At least, until the end.]]
* EvilCounterpart: Doofenshmirtz, obviously. Though that would probably count as an Eviler Counterpart. He's also an EvilCounterpart to Phineas, as shown in the final battle.
** Agent P's 2nd Dimension counterpart General Platyborg counts too since he also works for Dr. Doofenshmirtz-2.
* EvilHasABadSenseOfHumor: Doof 2. The only humor in his character comes from his crazy personality and the bad [[{{OneLiner}} one-liners]] he makes: otherwise, he doesn't share his counterparts sense of humor and even "dooms" him for it eventually.
* EvilIsPetty: Taken UpToEleven by Doof-2. While Doof-1 has come up with some admittedly petty schemes before (for equally petty reasons), they have nothing on [[spoiler:staging a full robot takeover of Danville just because he lost a toy train.]]
* EvilPlan: Doof-1 is as vague as usual but Doof-2 wants to [[TakeOverTheWorld take over the ''other'' Tri-State Area.]]
* EvilerThanThou: Doof-2 to our Doof. Doof-1 even uses the trope name when addressing him at one point.
* EyepatchOfPower: Doofenshmirtz-2, of course. And check out the LampshadeHanging mentioned below.
* FacePalm: Doof-2 does this when he sees that Doof-1 is completely unable to recognize Perry without [[ClarkKenting his hat]].
* FailureIsTheOnlyOption: (Regular) Candace, as usual and she knows it. See GenreSavvy bellow.
* FauxAffablyEvil: Doofenshmirtz-2 tried to kill Phineas, Ferb, Perry, Candace, [[AndYourLittleDogToo AND]] Doof-1.
* {{Fanservice}}: Just look at Candace-2.
** [[http://browse.deviantart.com/?qh=žion=&global=1&q=the+tiny+differences+candace#/d4b09ay A deviantART member]] has pointed out that she also happens to be slightly [[RealWomenHaveCurves curvier]] than her 1st Dimension counterpart. Make of that what you will.
* FilmWithinAFilm: Candace's parents spend the climax of the movie watching "That Darn Fiance". She arrived just as "[[RomanticComedy the girl is about to forgive the guy for the cliche misunderstanding]]".
** Right after she [[OutOfGenreExperience fights]] [[AllPartOfTheShow these robots]].
* FiveManBand: The main cast start to form some semblance of this towards the end of the movie, but it doesn't last long enough for it to fully manifest or for all the roles to be distributed clearly among the characters. We have Phineas as TheHero, Perry as TheLancer, Ferb as TheSmartGuy, Candace as TheChick, and Doofenshmirtz as TheBigGuy.
** From what we get to see of it, the second dimension resistance appear to form one.
*** TheHero: Candace-2
*** TheLancer: Isabella-2
*** TheSmartGuy: Baljeet-2
*** TheBigGuy: Buford-2
*** {{Tagalong Kid}}s/TheSixthRanger: Phineas-2 and Ferb-2
* FootPopping: [[spoiler:Done by Isabella when she kisses Phineas near the end of the movie.]]
* ForcefulKiss: [[spoiler:Isabella gives Phineas a short one at the end when their memories are about to be wiped.]]
* {{Foreshadowing}}: [[spoiler:Phineas mentions at the beginning of the movie that Perry seems to have missed all the stuff Phineas and Ferb have been doing all summer. The fact that Perry's hat had scanned a great deal of the inventions that the two brothers had made shows that [[CatchPhrase no, no he hadn't]].]]
* ForWantOfANail: The alternate universe branched off from the mainstream one when Doofenshmirtz didn't get a HilariouslyAbusiveChildhood, and only got one FreudianExcuse that the main Doof didn't have, allowing Doof-2 to become eviler and competent.
* FreudianExcuse: Doofenshmirtz-2 went evil(er) because his toy train when missing. Doofshmirtz-1 deconstructs this, pointing out that it's a ridiculous excuse for his behavior, especially when Doof-1 has far more excuses and isn't as evil.
** Doofenshmirtz-2 was already wearing the eye-patch back when he lost the toy train but he never uses the lost eye as a FreudianExcuse.
* FriendlyAddressPrivileges: Doof-1 introducing himself to Phineas-1 and Ferb-1.
-->'''Dr. Doofenshmirtz:''' I'm Dr. Heinz Doofenshmirtz, but my friends call me... ''(trails off, sighs)'' [[MadeMyselfSad I just got in such a funk]].
* FunnyBackgroundEvent: "MY WATERMELON!" This would later become a semi-RunningGag in the show.
* GenreSavvy: Doof-1 has a moment of this when he realizes his Otherdimensioninator ''doesn't'' need a self-destruct button.
** (Regular) Candace knows [[FailureIsTheOnlyOption that every time she tries to bust her brothers, events go in such a way that everything is back to normal, with the strange things disappearing just before her mom is able to discover it.]] [[spoiler:[[ExploitedTrope That said, she guarantees Doof-2's downfall by making good use of it.]]]]
* GettingCrapPastTheRadar: See [[Radar/PhineasAndFerb here]].
* GoLookAtTheDistraction: While trying to leave to face Doof, Perry [[ThrowingTheDistraction throws a pebble as a distraction]] which makes everyone turn and investigate. Phineas provides a lampshade.
-->'''Baljeet:''' Hey, what was that small noise?\\
'''Phineas:''' Let's all [[GoLookAtTheDistraction go walk over to it!]]
* HeartIsAnAwesomePower: Isabella's invention of choice is the little ''(aint' no) kiddie ride'' flying unicorn. She knows how to use it.
* HeelFaceTurn: [[spoiler:Doof-2 and Platyborg.]]
* HeroicSacrifice: [[spoiler:Phineas, Ferb, and their friends willing give up remembering the greatest adventure of their lives in order for Perry to stay. Shows just how much they care about that platypus.]]
* HoistByTheirOwnPetard: [[spoiler:Platyborg. Being partly machine gives him some advantages in fighting first dimension Perry. It's also why he ultimately loses.]]
* HopeSpot: [[spoiler:When the first dimension characters are chained and sentenced to doom, they actually manage to grab the keys, take out all the Normbots present, ''and'' shut the goozim's cage. Then the cage door falls.]]
** Also when Phineas, Ferb, and Perry are being pursued by Platyborg. [[spoiler:A Normbot looks like it's about to fall on Platyborg, but it misses. Then subverted when he gets hit by a bus instead.]]
* HorribleJudgeOfCharacter: An unfortunate side-effect of Phineas and Ferb's eternal optimism, it seems. They completely fail to realize that ''either'' of the two Doofenshmirtz's are evil until they're flat-out told.
** It can be argued that it is subverted in the case of how they judged [[AffablyEvil Do]][[HarmlessVillain of]][[AntiVillain -1]] and he was always nice and polite to them.
** Even though they've dodged adults early and often during the summer, it's a safe bet that they've never encountered one who was willing to [[spoiler:hurt them just to expose Perry.]]
** The same can be said of Phineas thinking Perry keeping his spy life a secret was because he didn't care about the family. If only he read that pamphlet.
* HowWeGotHere: The movie starts off with Phineas, Ferb, Perry, Candace and Doof-1 about to be executed, with Phineas thinking back to how the day started. Lampshaded once the story catches back up to that scene, when Phineas skips over most of his dialogue the audience already heard.
-->'''Ferb:''' Whoa. ''Deja vu''-ish.
* [[ImplacableMan Implacable Platypus]]: Platyborg. Nothing he gets hit with slows him down for long, aside from [[spoiler: [[{{CrowningMomentOfFunny}} a turkey]]]]. [[spoiler:Until Perry electrocutes him at the end, removing his evil.]]
* ImprovisedWeapon: During the encounter with the Norm-Bots in the mine cars, Perry uses the [[ChainPain chain he had previously been restrained with as a weapon]], Phineas pulls out [[WrenchWhack a wrench]] with the intent of using it as a weapon, and Ferb takes off his shoes and ties them together to create [[FightingWithChucks nunchucks]].
** In the same scene, they use one of the Normbots' arms as a bazooka.
** Several in the fight between Phineas and Doof-2. Including couch cushions, plates, a bowl of noodles, and a lamp.
** Technically, all of Phineas and Ferb's inventions used in the final battle, considering none of them were created with the intent of using them as weapons, even [[PoweredArmor the Beak suit]].
*** AbnormalAmmo: Comes in hand in hand with the above, with frozen yogurt, levitating remote-controlled baseballs, fruit, and Christmas presents being used to take out the Norm-bots.
**** [[{{CrowningMomentOfAwesome}} "Man, I wish other-dimension Candace was here. She took out like, 30 of them with a giant garden gnome."]] [[invoked]]
* InformedAttribute: In spite of numerous references to it, we never see Buford-2 really "resisting the Resistance", perhaps mirroring Buford-1's (also mostly Informed) status as a bully. He willingly helps Phineas and Ferb locate the Resistance for help, and even accompanies the ''bona fide'' Resistance members on their missions.
* InkSuitActor: [[Music/GunsNRoses Slash]] in the closing credits number. An odd case in that he doesn't actually have any speaking lines, he just [[CrowningMusicOfAwesome lets his guitar do the talking]].
* InsistentTerminology: When Doof-1 calls Major-2 his slave, he says he prefers 'indentured executive assistant'. Doof-2 is shown as using the latter term.
** Also Major Monogram stating he was sweating through his eyes instead of crying. Buford had previously used that term in [[WesternAnimation/PhineasAndFerb the series]].
** [[StylisticSuck Pretendy the Practicepus]] is not a doll, he's a stand-in.
* InsultBackfire: Used and thoroughly lampshaded by Doof-1 towards Vanessa in a DeletedScene.
-->'''Vanessa:''' You're not normal, Dad.\\
'''Heinz:''' Oh, why thank you Vanessa, you're so sweet! See what I did there? Even though I knew you meant it as an insult, I took it as a compliment. ''Maddening'', isn't it?
* InterdimensionalTravelDevice: The Otherdimensionator is one of these.
* InvulnerableKnuckles: An aversion played for an IronicEcho. During the climactic battle between Perry and Platyborg, Perry injures his hand punching Platyborg's armor-plated head and has to shake it off. Later, Perry dons football padding, and when Platyborg tries to punch him in the helmet with his organic hand, it shakes off the injury in exactly the same way.
* ItHasBeenAnHonor: [[spoiler:Just before the ResetButton comes into play]]:
-->'''[[spoiler:Phineas]]:''' [[spoiler:[[Film/StarTrekIITheWrathOfKhan You are now and always have been a great pet]].]]
* HypocriticalHumour: Stacy is a women of science-at least, that's what her horoscope said.
* KarmaHoudini: Played with. [[spoiler:At first it seems that Second Dimension Doofenshmirtz would get off free after getting his toy train back and becoming good, but then he walks through the portal, and is promptly arrested by the Second Dimension Resistance.]]
* KeystoneArmy: Doofenshmirtz-2 controls the Norm Bots using a satellite dish.
* LaResistance
* LampshadeHanging: In the ''trailer'':
-->'''Doofenshmirtz:''' I couldn't help but notice that your scar goes ''over'' your eyepatch...
** As they approach the DEI building, Phineas mentions they're going to hit that building that looks vaguely like Ferb's head.
-->'''Major Monogram:''' Remember, if your cover is blown, you'll have to leave the boys forever.\\
'''Doofenshmirtz:''' Does... does anybody hear someone talking?
* [[spoiler:LaserGuidedAmnesia]]: [[spoiler:The main cast willingly decides to forget what they have dubbed the greatest day of their lives so that Perry won't have to leave them all. [[TearJerker *sniff*]]]]
** A literal case too, as they accomplish this by being shot by the Amnesianator.
* LeaningOnTheFourthWall: Doof-1 finishes his duet VillainSong with Doof-2 with "Coming at you Fridays!", possibly referring to the premiere night of the movie as well as when new episodes of the series usually premiere.
** When Doof-2 [[spoiler:gets his Choo-Choo back, he says "Oh, heart melting. {{Backstory}} resolving! [[HeelFaceTurn Evil... diminishing]]."]]
* LetsGetDangerous: [[spoiler: Nearly ''all'' the characters and inventions do this, aside from the ones we already ''knew'' were badass.]]
* LittleMissBadass: Isabealla-2, along with all the other Firestorm girls.
* MagicSkirt: Despite the combination of skirt-wearing females, crazy acrobatics, and cinematic angles, there's somehow not a single PantyShot.
* ManlyTears[=/=]SingleTear: [[NotSoStoic Of]] ''[[NotSoStoic all]]'' [[NotSoStoic people]], both Ferb and his counterpart are seen each shedding one when [[spoiler:Phineas-2 ''thought'' he was reuniting with Perry]].
* MechaMooks: Doof-2's Norm-Bot's.
** In the climactic battle, the [[spoiler:Phinedroids and Ferbots]] are used as these.
** Doof-1's bots from the flashback.
* MoodWhiplash: After the cheerful and uplifting "Summer" song, we immediately cut to Perry being asked to turn himself in to save his owners. Made worse when Phineas notices and chews him out for it again, and "I Walk Away" plays... then Ferb makes a funny comment.
* MsFanservice: Candace-2, oh so very much.
* TheMovie
* MohsScaleOfScienceFictionHardness: Quite a bit harder than the average animated Sci-Fi flick. See "The Multiverse" for details.
* TheMultiverse: Though it's given some unique rules. First, it's not infinite, and you can travel through all of the universes one-by-one in a few minutes. Second, the universes are positioned in a clockwise formation, and it's a lot easier to travel that way, though this has the drawback of having you go through the entire multiverse to get back where you started. Going counterclockwise can be done, but it's very difficult.
* MundaneUtility: When Doof-1 first gets the Other Dimension-inator working, his first idea of what to do with it is... to replace his old, worn-out, [[ItMakesSenseInContext urine-stained]] couch with the much nicer one that occupies the same spot in the alternate dimension.
* NamesTheSame: {{Invoked}} {{in-universe}}. When Phineas and Ferb introduce their pet to Doofenshmirtz, he simply believes that there just ''happen'' to be two platypi in the Tri-State Area named Perry.
-->'''Doofenshmirtz:''' Is ''every'' platypus named Perry?\\
'''Phineas:''' In a perfect world, yes!
** The Agent T that appears in this movie and the game based on it has a different color scheme from the Easter Island-dwelling one from "Candace: Disconnected".
* NeverTrustATrailer: The scene of one of the treehouse robots pulling a Film/KingKong chest pound on top of a skyscraper? Never happens (except in a deleted scene).
** Other trailers make it seem like the battle is to keep Perry, or that '''their''' Candace leads LaResistance.
* NewNeighborsAsThePlotDemands: Despite Doof claiming that Mrs. Thompson has been his neighbor "for like, 12 years" she's never been seen before this.
** One could also get the impression Doof owned the whole building. [[RuleOfFunny So it just serves to delay Doof for a few laughs.]]
* NoPlansNoPrototypeNoBackup: Subverted. It's revealed that part of Perry's job is to photograph all of Doof's inventions so that the OWCA can rebuild and study them. [[spoiler:Perry's secretly done the same for Phineas and Ferb's inventions, and keeps them hidden in his lair in case of an emergency.]]
* NonActionGuy: Baljeet-2, even more noticeably than Baljeet-1. He isn't shown to accompany the other Resistance members on missions, for instance.
* NoodleIncident: The first time Doof-1 was sentenced to doom by a puppet.
** Doof-1's Amnesia-inator.
** When the tour bus for Love Handel is shot and toppled over by [[spoiler:the invading robot army from another dimension]], Danny looks around and says, "Ah great. Albuquerque '93 all over again."
* NotSoDifferent: The two Doofs, despite the latter being EvilerThanThou. The first thing they do is sing about how similar they are.
* NotSoStoic: Perry gets a great moment of this at the movie's climax when Platyborg gets a roast turkey stuck to his tail, and is unable to reach it to get it off.
** Not to mention he looked almost moved to ''tears'' when Phineas is [[PoorCommunicationKills chewing him out over not telling him and Ferb that he's a secret agent]].
** When Candace-2 is rescued from prison, hints of our Candace's Jeremy infatuation begin to surface.
** It's brief, but Ferb does shed a SingleTear when Phineas-2 ''thinks'' he's reuniting with Perry.
*** He is also just as scared as everyone else when running through the dimensions (well, at least the first one) and screams when [[spoiler: nearly getting thrown into a pit of lava]].
* OpeningShoutOut: The continent-painting helicopter and the giant robot dog (the latter of which only appeared in an episode as part of another OpeningShoutOut) help [[spoiler:fight off the Norm-bots alongside other inventions in the climatic fight scene.]]
** The ''Summer'' song takes some lyrics from the show's opening song. In fact, the "painting a continent" line uses the same animated sequence.
* OverprotectiveDad: A deleted scene shows that Doof-2 is even worse than Doof-1 in this regard, using his power to banish any boy who shows an interest in his daughter.
* PapaWolf: Perry doesn't even break his masquerade when the Platyborg punches him clear across the room. When that same robot moves to do the same to Phineas and Ferb, he immediately jumps up and punches him just as hard.
* ParrotExposition: Candace does this when Stacy tells her that as an adult, she doesn't need her mom to bust her brothers. Stacy Lampshades this.
* PoliceState: The Tri-State area under Doof-2's rule is tightly controlled via killer robots. They like to go around and ask for people's papers.
* [[PortalCut Portal Shave]]: The Goozim passes through the portal and ends up being cylindrical.
* PreAssKickingOneLiner: "Let's kick some robot chassis!"
** "Alright, you rust buckets, [[LetsGetDangerous let's dance]]."
* PunchPunchPunchUhOh: Agent P's first encounter with Platyborg.
* [[ReadTheFreakingManual Read The Freaking Pamphlet]]
* RebelliousRebel: Alternate Buford.
* ReforgedIntoAMinion: Platyborg to Doof-2.
* [[spoiler:ResetButton]]: Phineas and Ferb meet Dr. Doofenshmirtz for the first time! They find out Perry is a secret agent! So do Candace and the rest of the neighborhood (except Mom and Dad)! Isabella [[spoiler:kisses]] Phineas! They...[[spoiler:lose [[LaserGuidedAmnesia all their memories of this day]], so the movie has [[StatusQuoIsGod no impact on the show]] whatsoever.]]
** [[spoiler:Though Isabella didn't kiss Phineas until she knew the ResetButton was about to be pushed anyway.]]
* TheResistance: All the alternate kids seem to be a part of this. Buford-2 is so good at resisting, he even ''[[CrossesTheLineTwice resists the Resistance]]''.
** The alternate Phineas and Ferb weren't part of it, not until partway through the movie, anyway.
* TheReveal: Perry's secret agent status to the boys, of course.
** [[spoiler:Perry's been keeping copies of the boys' inventions hidden in his lair for an emergency...]]
** [[spoiler:During the dimension-hopping montage, it's revealed where [[RunningGag The Giant Floating Baby Head and the talking Zebra]] come from.]]
* RRatedOpening: The very opening of the movie, before "Everything's Better with Perry", clearly demonstrates that this movie will be DarkerAndEdgier than the show.
* SaveBothWorlds: It's in the plot.
* SelectiveObliviousness: Implied to be a character trait of Alternate Candace.
** Or that might be just part of her cover. 'Cause you know, being a resistance leader against the overwhelming oppression of a tyrannical mad scientist doesn't really demand that you stay out in the open in that role...
* SelfDestructMechanism: Thoroughly mocked, even more than usual. As it turns out, Doof-1's design for the Other-Dimension-inator didn't work ''specifically'' because of how he wired in the self-destruct button. When Phineas asks him whether he actually needed it, Doofenshmirtz starts to answer before [[EurekaMoment slowly realizing]] that he ''doesn't''. This is also apparently why Doof-1's attempt at a robot army didn't fare as well as Doof-2's (specifically, a rather unfortunate choice of placement for it). [[spoiler:Though it turned out that Doof-2 installed these in his robot army after all.]]
* ShoutOut: The title is a reference to TheAdventuresOfBuckarooBanzaiAcrossTheEighthDimension.
** The woman running away with the watermelon is also a reference to BuckarooBanzai's "why is there a watermelon there?" scene.
** The villain song in which Doof-1 and 2 are wearing pink outfits and working a conveyor is an homage to a classic episode of ''Series/ILoveLucy''. Another part of it has them as Creator/LaurelAndHardy and yet another as SherlockHolmes and Watson.
*** Also Music/TheBeatles, LoneRanger, [[TheHoneymooners Ralph Kramden and Ed Norton]], and Tonto and ... WesternAnimation/PhineasAndFerb ?
*** Also, at the end of the song, Doof-1 suggested he and Doof-2 "Coming at you Fridays!", which led to the following argument.
-->'''Doof-2''': What's that, are we doing a TV show together?
-->'''Doof-1''': Oh no. It just sort of sounded like that. Well, I mean, we could. We should!
-->'''Doof-2''': Hmm, maybe we're not so much alike.
-->'''Doof-1''': That can be your catchphrase! You're the grumpy one. [Pokes him] Huh?
** The scene in which Candace-2 is [[spoiler:locked in a cell and throwing a ball against a wall]] is a homage to a scene from ''Film/TheGreatEscape''.
** The line "I'm [[spoiler:Jeremy Johnson]] and I'm here to rescue you!" as well as Candace[[spoiler:-2's pose on the bench]] are lifted from ''StarWars''.
** The scene where Carl gives Perry several devices that will [[ChekhovsGun be useful]] is similar to how Film/JamesBond gets all his nifty gadgets from Q.
** Irving [[spoiler:as the bottom half of The Beak]]: [[Film/RedDawn1984 Wolverines!!]]
** The beginning song had a hint of ''Disney/TheLionKing'' in it.
*** It's also got a lot in common with the average Jackson5 song. Probably intentional, considering they've admitted to doing style homages before.
** When Phineas and Ferb first crash into Doofenshmirtz's Otherdimensioninator, he asks them how they got there, to which Phineas replies that they accidentally "[[TheJeffersons bounced on up to the East Side, to [Doof's] deluxe apartment in the sky]]".
** [[TheWizardOfOz "Fly! Fly, my Norm-bots!"]]
** SteamboatWillie itself appears in the console video game adaptation.
** [[spoiler:[[SantaClausIsCominToTown Doof-2's "heart melting" when he's given a "choo-choo"]]. He even cuddles it up to his face.]]
** In the beginning of [[EverythingsBetterWithPlatypi Everything's Better With Perry,]] when the boys are asleep, Ferb is shown holding a copy of Literature/TheOdyssey.
** The movie Lawrence and Linda watch is called ''[[Film/ThatDarnCat That Darn Fiance]]''.
** Perry's tag/locket/picture frame/key looks like the Batman symbol. And just like Batman he's crazy prepared with all sorts of gadgets
** [[spoiler: "[[Film/StarTrekIITheWrathOfKhan You are now, and always have been, a great pet]]. [[TearJerker And a great friend.]]"]]
** [[spoiler: [[WesternAnimation/RecessSchoolsOut Phineas destroys the satellite with a baseball]]]].
** The video game adaptation has a level set in a 1920s cartoon world, somewhat like [[VideoGame/KingdomHeartsII the Timeless River]]. Part of it even takes place on [[SteamboatWillie a steamboat]].
* [[SirNotAppearingInThisTrailer Sir Not Appearing In This Movie]]: Olivia Olson is listed in the credits as Vanessa, but she (and her alternate counterpart) only appear in deleted scenes.
* TheSociopath: Somewhat PlayedForLaughs with Doof-2. He has no contrived backstory for why he's evil. He just lost his favorite toy...and that was it. Which shows he is truly evil because of what was inside him from the start, as opposed to warped and frusterated to petty degrees due to a traumatic childhood and AbusiveParents like Doof-1 is.
* SplitPersonality: The Normbots.
* [[spoiler:StatusQuoIsGod]]: [[spoiler:This trope can stink a lot of times, but this time, it's a real TearJerker. Even in-universe.]]
* StealthPun: What does Doofenshmirtz's couch end up covered in? [[spoiler:''Agent Pee''.]]
* [[SandInMyEyes Sweating Through My Eyes]]: Major Monogram wasn't crying during [[spoiler:Perry and the boys' touching good-bye.]]
* TemptingFate: Doofenshmirtz talks about how his Otherdimensioninator hasn't been destroyed yet. Then the boys' shuttlecock slams into it.
* ThemeTuneCameo: A verse of the show's theme song pops up in the middle of another song.
* ThrowingTheDistraction: See GoLookAtTheDistraction above.
* TimeStandsStill: The alarm clock goes off at 7:00 am. The boys go through an extend montage for "Better with Perry", including making popcorn and the clock is still at 7:00 am.
* TrailersAlwaysSpoil: [[spoiler:The topiary gag would have worked a lot better if the trailers didn't already tell you that Candace was the leader of the Resistance.]]
** Fans also knew right from the start that Phineas and Ferb's old inventions would be making a comeback. Didn't stop it from being awesome, though.
* TroperCriticalMass: You think?
* TwoWordsObviousTrope: Candace objected to Phineas' idea of having Perry [[ItMakesSenseInContext drop them all into a pit of lava]]. Why? "Two words. La-va!"
* UnConfession: Phineas's love interest, Isabella, kisses him just seconds before their memories are erased.
* UnusuallyUninterestingSight: Doofenshmirtz doesn't think that much of the fact that Phineas and Ferb randomly flew in on a giant shuttlecock; well, other than the fact that it resulted in the destruction of his -inator.
* UnwillingRoboticisation: Doofenshmirtz-2 had inflicted this on Perry-2 long before the events of the movie, and he intends to do the same thing to our Perry and Phineas at the movie's climax.
* UtilityBelt: Mostly used to weigh down the MagicSkirt.
* VagueAge: Given a nice LampshadeHanging by Doof-2.
-->'''Phineas:''' How old do you think we are?\\
'''Doof-2:''' I don't know, 1, 2, 3, It's hard to tell with the ONE EYE!!!
* VengefulVendingMachine: Mentioned in Dr. Doofenshmirtz's getting-to-know-you duet with his alternate-dimension counterpart:
--> Doof-2: Do you collect coins?
--> Doof-1: Yeah! Just in case -
--> Both: - vending machines become the dominant race!
** And then called back in an episode, when Doofenshmirtz gets hit by an Inator that causes his greatest fear to materialize... enter the vending machines...
* [[VillainWorld Villain Dimension]]: The second universe dominated by Doof-2.
* VillainSong: [[http://www.youtube.com/watch?v=u_Ov4eN67lE&feature=feedu "Brand New Best Friend (and It's Me)"]] by the two Doof's.
** [[EvilerThanThou Doof-2]] also gets a verse in [[CrowningMusicOfAwesome Kick It Up a Notch]], backed up by [[EvilCounterpart Platyborg]].
* VillainTeamUp: Subverted. Both dimension Doofenshmirtzes are at first overjoyed to meet one another, but Doof-2 soon betrays Doof-1 when he realizes that Doof-1 isn't as good at being evil as he is.
* VillainousRescue: Doofenshmirtz saves Phineas, Ferb, and Perry from being crushed by Doofenshmirtz-2 at the end of the final battle.
* VillainsNeverLie: Granted, when Doof-2 promised to spare Phineas and Ferb if Perry turned himself in, he didn't realize that he needed Phineas's help until after Perry took him up on it. He's not exactly apologetic about the situation, though.
** Also, Doof-2 explaining to Phineas and Ferb that Perry only saw them as a cover for his job as a secret agent and didn't actually care about them. Then again, he may or may not have [[EvilCannotComprehendGood genuinely believed this to be true]].
* TheVoiceless: Ferb-2. His entire dialogue throughout the movie is one line during "Summer (Where Do We Begin?)"
** As in the original show, Ferb-1 nearly qualifies. Excluding "Kick It Up A Notch", He has a total of six lines in the movie. He shares his first line with Phineas and another is the other is sung during "Summer (Where Do We Begin?)"
** The Various O.W.C.A. Agents
** The Firestorm/FireSide Girls
** Danny and Stacy are the only named characters to speak in the movie without having a 2nd Dimension Counterpart shown. (A Weathercaster and a Newscaster had a single line.) Danny gets two lines.
** Bobby and Swampy of Love Handel don't speak at all.
* WasItAllALie: That's how Phineas feels when they find out Perry's a secret agent and that's why he's upset with Perry. ''Again'', he gets over it rather quickly, but at that moment, he felt that all these years, his friendship with Perry was a lie.
* WhamLine: "Do the same thing...to those two boys." [[spoiler: *PUNCH*]]
** The reveal of the members of the resistance ([[spoiler: "Watcha DOIN'?"]]), followed by the reveal of their leader: [[spoiler: "Who made the topiary out of wild parsnips?"]]
* WhatMeasureIsANonHuman: No one raises the moral objections of trashing the Norm Bots even though they show signs that they have emotions. One even says "I use aggression to mask my insecurities". Also, when a group of them are confronted by Ferb with the robot bulls, one of them pushes another out of the way trying to escape, meaning that they have self-preservation and ''fear death''.
** On the other hand, they're an invading army, so the heroes aren't exactly given time to weigh the philosophical conundrum.
* WhatTheHellHero: ...And Phineas is actually pretty upset when they first find out, even if they do get over it by the second act.
-->'''Phineas:''' So all this time, we're like "[[SarcasmMode Oh, he's a Platypus.]] [[CatchPhrase They don't do much.]]" Well, apperantly, THEY DO!!\\
'''Perry:''' (Gives him a pamphlet)\\
'''Phineas:''' (reading) So you just found out your pet's a Secret Agent-- [[CrowningMomentOfFunny I DON'T WANT YOUR PAMPHLET!!!]]
** Part of it was because Perry didn't stop them from helping Doofenshmirtz with his plan.
---> '''Ferb:''' Well, he did pee on the couch.
** Comes up again when [[spoiler:Candace-2 abandons the first dimension characters, leaving Phineas-2 arguing how unfair it was. [[BigDamnHeroes She helped them later on though]].]]
* WimpFight: When Baljeet tries on "The Beak" PoweredArmor P&F made, slap fighting is all he can do. Fortunately the armor makes it still work.
* TheWorfEffect: [[spoiler:Danville's animal agents, besides Perry, are quickly defeated by the Norm Bots. Even Perry himself gets a bit of this during his first fight with Platyborg, but it just serves to make his eventual victory all the more awesome.]]
* WouldHurtAChild: Doofenshmirtz-2.
* XMeetsY: The basic plot of this movie is the usual Phineas and Ferb A-Plot coming into contact with the Agent P B-Plot.
* YouWillKnowWhatToDo: [[spoiler:Said by Perry's computer when the boys find their way into his hideout.]]
** [[spoiler:For a moment, they ''don't'' know... [[CrowningMomentOfAwesome until the computer shows them what they have to work with]].]]
