History FreakyFridayFlip / WesternAnimation

** Parodied again in one episode where Stan and Steve switch ''eyebrows''.

** Happens in the second season with Jake and his younger sister Haley. Jake would help Haley win a dance comeptition while Haley helped Jake patch things with Rose.

* ''WesternAnimation/TeenTitans'' has an episode called "Switched" which switches Starfire and Raven. The voices switch in this version too, but the reason is apparently not due to appeasing children; Creator/HyndenWalch and Creator/TaraStrong were apparently able to duplicate one another's voices for their respective characters so well, the producers thought it would be pointless to continue having them voice one another's characters.

* In ''WesternAnimation/PAWPatrol'', this happens between Chase and Chickaletta in "Pups Save a Freaky Pup-Day", and Chase must complete the mission while in Chickaletta's body. [[spoiler:It turns out to be AllJustADream, though.]]

* LastOfHisKind: Snorp is initially the last of his species,

** Peter and Lois briefly switched places due to one of Stewie's inventions. [[https://www.youtube.com/watch?v=DMynC4twXV8 Peter does what you would expect.]]

* The ''WesternAnimation/JusticeLeagueAction'' episode "Mxy's Mix Up" has Mr. Myxzipitlk swap the bodies of Superman, Batman and Stargirl so that she's in Supes' body, Bats' in hers, and Supes' in Bats'. He eventually gets most of the League swapped.

** This is possibly one of the most FridgeLogic heavy examples of this trope: how do you switch ''bodies'' with ''the spirit'' of the Earth?
*** Do not even ''try'' to come up with some sort of internal consistency on that show about how spirits work, including whether or not Gaia floats around Hope Island like a sparkly ghost or walks around like a flesh-and-blood human.
*** It's possible that she can switch between being spiritual and bodily at will, at least as long as she's on Hope Island.

* In the ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "Trading Faces", Jimmy's attempt at listening in on Cindy to find out her latest prank so he can avoid it is thwarted by a sudden lightning storm that causes Jimmy and Cindy to switch bodies. They spend most of the episode torturing each other before their discontent for being in each others' bodies leads Jimmy to reverse it. Uniquely the process isn't simple, as their minds are melded into a computer bank and Carl, Sheen and Libby have to manually sort the two's traits and memories into their respective bodies. There's a sticking point where one trait recursively lists the dislike of boys who dislike girls who dislike boys and so-on ad nauseum. They eventually decide to just delete that one, which might have been the beginnings of Jimmy and Cindy's ShipTease.

** The episode "Dogs Day Afternoon" had Timmy switching places with Vicky's dog. It backfires when Timmy finds he can only use AnimalTalk and can't unwish the wish.

* ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'' had Spyro swap bodies with a dog because Mentok the Mindtaker ([[CatchPhrase OOO-EEE-OOO!]]) got bored in court. Mentok's then forced to take care of Spyro's body when he loses Spyro's mind, going back and forth between having a dog's mind and a toddler's mind in his body. Turns out Spyro's mind was in someone's ass. It MakesJustAsMuchSenseInContext.

* In the ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "Trading Faces" Jimmy's attempt at listening in on Cindy to find out her latest prank so he can avoid it is thwarted by a sudden lightning storm that causes Jimmy and Cindy to switch bodies. They spend most of the episode torturing each other before their discontent for being in each others' bodies leads Jimmy to reverse it. Uniquely the process isn't simple, as their minds are melded into a computer bank and Carl, Sheen and Libby have to manually sort the two's traits and memories into their respective bodies. There's a sticking point where one trait recursively lists the dislike of boys who dislike girls who dislike boys and so-on ad nauseum. They eventually decide to just delete that one, which might have been the beginnings of Jimmy and Cindy's ShipTease.

* In the ''WesternAnimation/CaptainSimianAndTheSpaceMonkeys'' episode "Escape from the Plant of the Apes", Captain Simian and Shao Lin switch bodies. HilarityEnsues -- but it's well thought out hilarity. VoicesAreMental is {{averted|Trope}}; not only do Simian and Shao Lin's voices stay in their original bodies, but their voice actors (Jerry Doyle and Karen Maruyama) use each others' speech cadences while their characters are switched. As noted above, these details are usually overlooked in "Freaky Friday" Flip stories.

* An episode of ''WesternAnimation/TheFlintstones'', "Monster Fred", does this. The method is via a mad scientist's so-called "Personality Swapper", but the episode plays out like this trope. (Complete with VoicesAreMental in effect.) Long story short, Barney inadvertently takes an injured Fred (with Dino in tow) to a mad scientist's lab, who immediately switches Fred and Dino around. HilarityEnsues for the rest of the episode with more switches occurring. First with Fred and Barney, then the husbands with their respective wives, then Dino with the mad scientist's assistant before everyone is finally restored to normal...except for the mad scientist who now thinks he's Fred. Adding to the hilarity is that no one seems to notice that they've become one of the other characters, Fred thinks everyone's being ridiculous when they're telling him that he is now his pet Snorkasaurus.
* In one of the Comedy Central episodes of ''WesternAnimation/{{Futurama}}'', "[[Recap/FuturamaS6E10ThePrisonerOfBenda The Prisoner of Benda]]", the Professor perfects a mind-switching machine, only to discover that the "brain immune response" making it impossible for a given pair of bodies to swap more than once. Soon the entire cast is switching bodies for various reasons (reliving one's youth, showing up one's girlfriend, stealing the crown of the Robo-Hungarian emperor, etc.), and confusing HilarityEnsues. This is one example of voice-actors changing despite the show being adult-orientated, as the large number of characters changing means that even an adult would have difficulty keeping track of it all.

* Happens in the ''WesternAnimation/GravityFalls'' episode, "Carpet Diem", where Dipper and Mabel switch bodies and compete over a new room they found in the shack. While the twins compete, [[HilarityEnsues Soos and Waddles]] switches bodies as well. The episode ends in a free-for-all with Dipper, Mabel, Soos, Waddles, Candy, Grenda, Sheriff Blubs, Deputy Durland and Old Man [=McGucket=] all getting swapped around.

* In ''WesternAnimation/TheRealGhostbusters'' episode "Slimer, Is That You?", ascetic Ghostbuster Egon and gluttonous ghost Slimer switch bodies. HilarityEnsues.

* One episode late in the run of ''WesternAnimation/RoliePolieOlie'', "Big Babies", has an accident with one of Mr. Polie's inventions result in Olie himself swapping bodies with his pet dog Spot and babies Coochie and Coo swapping with Mr. and Mrs. Polie. HilarityEnsues.

* ''WesternAnimation/ShaunTheSheep'' episode "Cat's Got Your Brain"; the aliens switch Shaun's brain with Pidsley the cat. HilarityEnsues.

** Also implements HowDoIShotWeb; Starfire's race openly display their emotions to use their powers (such as joy for flight or righteous fury for starbolts) while Raven has to suppress her emotions just to keep her powers under control. HilarityEnsues as they struggle to adjust while having to stop the Puppet King, who has trapped the other Titans' souls in puppets and using the empty bodies as weapons (the souls of Starfire and Raven got switched due to interference).

* The ''WesternAnimation/TransformersRescueBots'' episode "Switcheroo" features most of the main cast getting swapped around due to [[AppliedPhlebotinum particles in space from a meteor combining with a crystal on the group's ship]]. Exact pairs are Kade/Heatwave, Dani/Blades, Cody/Boulder (Graham was not involved in the swap at all, much to his relief), Chase/Frankie and Chief Burns/Doctor Green; naturally, HilarityEnsues. VoicesAreMental is utterly averted, as the whole episode idea came from the characters' voice actors doing imitations of one another during recording sessions, so they have every aspect of each other's characters down pat.

* In the ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'' episode "Trading Faces" Jimmy and Cindy switches bodies. They spend most of the episode torturing each other before their discontent for being in each others' bodies leads Jimmy to reverse it. Uniquely the process isn't simple, as their minds are melded into a computer bank and Carl, Sheen and Libby have to manually sort the two's traits and memories into their respective bodies. There's a sticking point where one trait recursively lists the dislike of boys who dislike girls who dislike boys and so-on ad nauseum. They eventually decide to just delete that one, which might have been the beginnings of Jimmy and Cindy's ShipTease.

* In the ''WesternAnimation/ActionLeagueNow'' episode "Hey! Who Stole My Face!" the League follows The Mayor's orders and The Chief is put in jail. However, the two didn't really switch bodies; an operation after a blender mishap simply results with one having the other's face.

%% This page has been alphabetized. Please add new examples in the correct order.

** "Which Is Which", a season 10 episode, sees this happening to Timmy and Chloe.

* ''WesternAnimation/ZigAndSharko'': In "Me, Myself and I", after a mishap with an electric eel, Zig and Sharko exchange minds. Zig-in-Sharko naturally tries to take advantage of it to eat Marina, while Sharko-in-Zig attempts to stop him. Being now the physical underdog, he quickly opts for aiming at reverting the switch with the electric eel; several more mind exchanges happen before the eel is too drained to keep it on, at which point they're back in their respective bodies.

* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', Jimmy and Cindy switches bodies. They spend most of the episode torturing each other before their discontent for being in each others' bodies leads Jimmy to reverse it. Uniquely the process isn't simple, as their minds are melded into a computer bank and their friends have to manually sort their traits and memories into their bodies. There's a sticking point where one trait recursively lists the dislike of boys who dislike girls who dislike boys and so-on ad nauseum. They eventually decide to just delete that one, which might have been the beginnings of Jimmy and Cindy's ShipTease.

** Played straight in the episode "Presto-Change-O", which involves a body-swapping joy buzzer.

* ''WesternAnimation/ZigAndSharko'': In "Me, Myself and I", after a mishap with an electric eel, Zig and Sharko exchange minds. Zig-in-Sharko naturally tries to take advantage of it to eat Marina, while Sharko-in-Zig attempts to stop him.

An unintentional example occurred in Hanna Barbera's Adventures of Gulliver when Bunko and Eager's voices were switched for one line each.A continuity problem.

In Geronimo Stilton at the end of Incredible Shrinking Stiltons, the bodies of mouse Trap and a police dog are switched [[/folder]

* Parodied wonderfully on ''WesternAnimation/AmericanDad''. In the "Rough Trade" episode, Stan and Roger get into an argument over whose life is easier, and end up both saying "I wish we could trade places!" while touching an Incan bowl that supposedly grants wishes. At that moment, the lights began flashing and a strange moan is heard... and it turns out to be Klaus, playing with the light switch and making funny noises. Nothing magical happens, but the two decide to trade lives anyway.
** Klaus later says that "if that had been a real wish-granting bowl, it would be in the back seat of a Ferrari driven by a 600-year-old Incan on his way to his job as Creator/JessicaAlba's G-string."

* ''WesternAnimation/AmericanDragonJakeLong'' had this happen in the second season with Jake and his younger sister Haley. Jake would help Haley win a dance comeptition while Haley helped Jake patch things with Rose.

* On ''WesternAnimation/FamilyGuy'', Peter and Lois briefly switched places due to one of Stewie's inventions. [[https://www.youtube.com/watch?v=DMynC4twXV8 Peter does what you would expect.]]

** This becomes the main plot of the episode "Switch the Flip". It starts out with Brian and Stewie swapping bodies via the latter's latest device. When they attempt to switch back, unfortunately, Chris and Peter get caught in the mix. Eventually, Stewie's device causes everyone within the vicinity of Quahog to switch bodies with hilarious results.

* In one of the Comedy Central episodes of ''WesternAnimation/{{Futurama}}'' the Professor perfects a mind-switching machine, only to discover that the "brain immune response" making it impossible for a given pair of bodies to swap more than once. Soon the entire cast is switching bodies for various reasons (reliving one's youth, showing up one's girlfriend, stealing the crown of the Robo-Hungarian emperor, etc.), and confusing HilarityEnsues. This is one example of voice-actors changing despite the show being adult-orientated, as the large number of characters changing means that even an adult would have difficulty keeping track of it all.

** ''Anime/DemashitaPowerpuffGirlsZ'' has also done a version of this, with the girls swapped with each other (AnAesop quickly follows).

** In "The Old Switcheroo", During a battle against each other, Splinter and Shredder were accidentally hit with a machine that switched their bodies. [[VoicesAreMental Although they still had their real voices in thought]], [[VoicesAreNotMental they had the voice of the body they switched with when speaking out loud]], which makes the Turtles, April, Shredder's mutants and Krang clueless about the mind switch. However, due to his kind demeanor, Splinter in Shredder's body tried to hide his identity from Bebop, Rocksteady and Krang, even fooling them when a brain-scan machine was used on him by [[HeroicWillpower controlling his brain waves]]. Meanwhile, Shredder in Splinter's body made it easy for the Turtles to get suspicious as they and April decided to look for answers about his behavior, which led to a confirmation with Bebop, Rocksteady and Splinter. After dealing with Bebop and Rocksteady, the Turtles surround Splinter as he tries to tell them that he's not really Shredder but they don't believe him. However, Splinter was able to [[CassandraTruth convinced]] the Turtles that its really him but trapped inside Shredder's body. After everything was explained, the Turtles devised a plan to get Splinter and Shredder back in their correct bodies, which they succeeded despite Bebop and Rocksteady interfering.
