History Main / TemporaryBulkChange

** In "Connie's Celica", Lois bulked up a good deal while in prison.

While this can be [[TransformationCauses caused]] by [[AWizardDidIt magic]], superpowers or science, it can also be caused by something that can realistically change someone's size. Even if this is the case, though, it'll likely happen at an unrealistically quick pace. Seldom will a character experience issues, from either the change to or the reversion from the new size, and if this temporary size is bigger than their normal size, they'll never suffer from excess skin, even if they lose the weight in an instant.

When used over the course of an episode, it may be an element of AWeightyAesop. Shorter-term instances may be used for sight gags or [[YouAreFat fat jokes]].

In most western animations and anime, you have a character whose size can moderately or drastically change for just a few minutes as the scene calls it, or even for the whole episode. However, when the scene or episode ends, usually the affected character will be back at their regular size as if nothing ever happened. Characters may either [[ShapeshifterBaggage gain weight, lose weight]], [[GrowingMusclesSequence grow muscles]], or [[InflatingBodyGag be inflated with air or liquid]] according to the script. Rarely used in live-action television and/or film since the actor has to wear heavy padding and special make-up, which is expensive and makes them very uncomfortable.

* In chapter 59 of ''Manga/AiKora'', Ayame overeats (over the course of a couple of weeks) due to stress from a scandal at her father's company and becomes rather obese. When she hears that the scandal was cleared and the company's stock had gone back up, she reverts back to her slim figure ''instantly''. Meanwhile, Hachibei had been intercepting all of Ayame's food during the day and grew as bloated as Ayame had been in just a day. At the end of the chapter he throws all of it back up, and by the next chapter he's back to normal.

* One episode of ''Series/BigWolfOnCampus'' has Merton go from thin to ''morbidly'' obese in a matter of days after befriending a group of black-clad teenagers. It turns out they're actually SpiderPeople who are intentionally [[FatteningTheVictim fattening him up to eat]].

* In the puppet show, ''Series/BetweenTheLions'', the pigeons Walter and Clay got extremely fat after eating all of the popcorn in order to clean up the roof garden in The Popcorn Popper. Instead of flying, due to their heavy weight, they roll away instead. Luckily, they return back to normal by the next episode.

* ''Series/ThatsSoRaven'' has "Food for Thought," an episode which points out that [[AWeightyAesop too much junk food leads to terrible health.]] Raven's high school cafeteria is bought out by a fast food corporation which slowly introduces more and more insane amounts of unbelievably fatty foods until even the halls are full of freebie hot snack machines to keep them hooked. Obviously, almost every student is said to be getting noticeably fatter, even though no actual change is visible.
** Raven even struggles just to stand up from the sofa, despite no actual prosthetics to suggest any weight gain.
*** At that point is was more about a lack of energy from eating the junk food rather than any weight concerns. However, Raven does have a vision of a [[BigFatFuture in which everyone in the school grows a gigantic behind because of the unhealthy cooking.]]

* ''VideoGame/MarioAndLuigiBowsersInsideStory'': The plot is kickstarted by Toads contracting the Blorbs; an ailment that causes them to swell up into a large spherical shape.

* In ''Webcomic/ElGoonishShive'', Nanase and Ellen [[http://egscomics.com/egsnp/2009-12-01 play]] VideoGame/FableII and Nanase uses the XP she's earned to become more powerful which results in becoming taller and bulkier. She also consumes pies to keep her HP up which results in becoming [[{{Acrofatic}} fatter]]. She then assures Ellen that celery will [[HyperactiveMetabolism fix that]] and, according to Dan in TheRant, she's right.

* In the ''WesternAnimation/AmericanDad'' episode "Shallow Vows", Francine gets very fat after she stops trying to look pretty for Stan as a test of love to see if he would still love her even if she was fat and ugly.

* WesternAnimation/{{Chowder}} often overeats himself into a huge ball, then deflates back to normal with one burp.

* ''WesternAnimation/FamilyGuy'' has at least three cases of this trope:

* Amy on ''WesternAnimation/{{Futurama}}'' used to be fat as a kid, so when the entire crew become younger in "Teenage Mutant Leela's Hurdles", she regresses to her childhood weight as well.

* Henry and June on ''WesternAnimation/KaBlam'' in a season four episode, where they gain weight from overeating and have to lose weight for an upcoming physical fitness test, and if they fail, they lose their jobs as hosts of the show. So who do they call in to help them? Richard Simmons.
** This gets subverted though, because the two of them don't lost any weight and prepare to get fired, only to discover the physical was to test them on surviving ''cartoon'' physics. The test literally involved dumping two anvils on them, which they walked away from without a scratch.
* ''WesternAnimation/TheLifeAndTimesOfJuniperLee'': In "Magic Takes a Holiday", Juniper's pug Monroe takes a liking to the cook at her drama camp. Monroe gains weight after being served so much food, to the point where he tries burning it off on a treadmill during the credits.

* On the episode "Suds", WesternAnimation/SpongeBobSquarePants gets the sponge equivalent of a cold, which causes bubbles to come out of his pores every time he sneezes. In an attempt to keep him from going to the doctor, Patrick plugs up [=SpongeBob=]'s pores, causing him to swell up with every sneeze.

* ''ComicStrip/{{Peanuts}}'' had a 1982 story arc where Sally went to Bean Bag Camp, where all kids do is sit in their bean bags watching TV and eating junk food, and came back fat. After 4 strips with fat Sally she was suddenly back to her normal self.
** Snoopy's brother, Spike, went through this when he came to visit, and Lucy, who was taken aback by his scrawny physique, decides to fatten him up. He ends up going from thin to fat and back to thin again in a matter of days, much to everyone's surprise.

* A much more extreme example of this trope occurs in ''WesternAnimation/ScoobyDooMysteryIncorporated'' during "The Devouring." Shaggy and Scooby get tasked with eating all the gluten-retaining food in Crystal Cove to stage a trap for the destructive Gluten Demon. Instead of only getting swollen bellies, Shaggy and Scooby become ''huge'' and are "too full to be scared" when the monster shows up. However, their morbidly obese bodies are strong enough and durable enough to take on the rampaging and equally large Gluten Demon and defeat it.

** In ''WesternAnimation/WabbitTwouble'' from 1941, Elmer Fudd, in a case of EarlyInstallmentWeirdness, is more obese than in more modern portrayals (he like this in only four cartoons, including this one). At one point Elmer barricades Bugs Bunny's rabbit hole and laughs, and later Bugs pops out from under the barricade and [[CopycatMockery mocks him]], [[NarrativeShapeshifting morphing into Elmer's overweight shape]]. The image of the overweight Bugs has since been given the FanNickname of "[[MemeticMutation Big Chungus]]".

** Peforming the Snack Basket. Bros. Attack has Luigi chow down on a series of desserts, bloat to a massive size, and slam into the ground, creating a shockwave.

** A more subdued and realistic version occurs in "Lisa's Belly" when Bart and Lisa are forced to take steroids after suffering a nasty infection from expsoure to polluted water. One of the side effects is a mild and temporary weight gain which results in both spending the episode looking slightly chubbier than normal. The plot's driven by Marge accidentally insulting Lisa by playfully stating she's "chunky."

* In the second issue of ''ComicBook/MyLittlePonyLegendsOfMagic'', Rockhoof foregoes his training sessions to take on numerous eating challenges. When the volcano starts showing signs of life again, Rockhoof has fattened up to the point where he has trouble climbing the mountain. When he makes it there, his bulk impedes him from fighting a cherufe which results in a stern talking to from Captain Steela. Rockhoof then exercises the weight off much faster than he put it on, and he becomes more muscular than ever before.

* This is a power ([[BlessedWithS
* In ''Webcomic/StarImpact'', [[GirlyBruiser Lily]]'s [[EveryoneHasASpecialMove special glove power]] is to temporarily buff up whatever part of her body that she wants. This is shown to have more applications beyond a mere [[TheRightHandOfDoom Right Hand of Doom]] EnhancedPunch, however, as she can also use it to buff up her leg muscles to dart in and out of her opponent's range and perform withering hit-and-runs, and can also buff up her abdomen to better soak up body blows. Even without using it, [[LightningBruiser she can be zippy and nimble while still being able to hit like a truck at any moment]], and [[MentorArchetype Stryker]] points out that, on paper, she has no real weaknesses.uck well more of a curse]]) of Aisha from ''Webcomic/SlimyThief''. When she touches water she adsorbs it and gets fatter but losing the water slims her down.

* One story arc in ''Webcomic/SequentialArt'' had Art being temporarily fattened up thanks to a prank pulled by Scarlet and her sisters. After struggling to lose weight for several strips, he's returned to normal size after [[spoiler:alien robots who want to eliminate him because he's WalkingTechbane shoot him with a disintegrator ray, but only manage to burn off the excess bulk.]]
* The fox in ''WebComic/TallyHo!'' learned too late not to eat the gravy meant for Sigfried. He became an immobile furry ball, but it lasted only two strips. Not to say he was fortunate, because [[NauseaFuel the end of his digestion felt horribly thorough]].
* This is a power ([[BlessedWithSuck well more of a curse]]) of Aisha from ''Webcomic/SlimyThief''. When she touches water she adsorbs it and gets fatter but losing the water slims her down.

* [[BigGuy Rak Wraithraiser]] from ''Webcomic/TowerOfGod'' once got shrunk to half a man's height (he was initially 4 m tall) because he accidentally bumped into Yu Hansung and didn't apologize, instead he made comments about how small and unnoticeable he was. So Yu Hansung kept bumping into the chibified Rak over and over, saying how he was so small he didn't notice him. Justified in that Compression is an often used supernatural technique in this series.
* In ''Webcomic/ElGoonishShive'', Nanase and Ellen [[http://egscomics.com/egsnp/2009-12-01 play]] VideoGame/FableII and Nanase uses the XP she's earned to become more powerful which results in becoming taller and bulkier. She also consumes pies to keep her HP up which results in becoming [[{{Acrofatic}} fatter]]. She then assures Ellen that celery will [[HyperactiveMetabolism fix that]] and, according to Dan in TheRant, she's right.
** Susan similarly grows fatter in a similar game, "Parable", after testing out a potion [[https://www.egscomics.com/egsnp/parable-026]] given to her by [[PunnyName Dea Elsee]] the alchemist, after removing her cool Victorian-type suit beforehand.

* ''Webcomic/DiamondAndDazzle'':
** Diamond Tiara gets one in World 3 of the Adventure arc. Having [[BodySwap swapped bodies with Dazzle]], she [[StockAnimalDiet catches a whiff of]] [[VideoGame/TheLegendOfZeldaMajorasMask Gyorg]] and finishes him off with a 97-chomp combo. She spends the entirety of World 4 overweight, unable to keep up with Dazzle until she burns it off.
** In the Life arc, Diamond and Il the Imp have been turned into cats. This time, the smell of Fishface the [[VideoGame/{{Splatoon}} Torpedo]] does both of them in. Unlike in the Adventure arc, they can't shake off the excess weight by playing through so they stop at a gym to exercise until they become normal again.

* In ''Animation/RedShoesAndTheSevenDwarfs'', the title female character keeps her thin, perfect hourglass figure through the use of her red, magical shoes. Once she takes them off her waistline increases significantly.

* Amy on ''WesternAnimation/{{Futurama}}'' used to be fat as a kid, so when the entire crew become younger in "Teenage Mutant Leela's Hurdles", she regresses to her childhood weight as well. In "The Prisoner of Benda", the cast goes through a series of {{Body Swap}}s, and when Amy ends up on Leela's body, she starts overeating again, resulting in a fat Leela. Hermes offers to swap minds with her, claiming that Amy's overeating couldn't make his body any worse. When everyone's minds are back in their proper bodies at the end of the episode, Leela is back to normal, and Hermes has become thinner as well, after both saw [[spoiler:Fry and Leela making out in Farnsworth's and Zoidberg's bodies]] and lost their appetites.

* Buccha from ''Manga/AirGear'' can do this as it's explain most of the fat is blood pooling in his stomach from overeating. When he wishes, he can transfer it to his muscles to give himself a more impressive build.

* In the first 3 episodes of season 2 of ''Series/{ThirtyRock}'', Jenna, because of her eating 4 slices of pizza during all of her performances of Mystic Pizza: The Musical, Jenna has gained a pot belly that only lasts until episode 4.

*** At that point is was more about a lack of energy from eating the junk food rather than any weight concerns. However, Raven does have a vision of a BigFatFuture in which everyone in the school grows a gigantic behind because of the unhealthy cooking.

* In the ''Film/EpicMovie'', a parody of Mystique is present throughout most of the film by the stunning, thin, hourglass figured woman Carmen Electra. However, during the sex scene between her and the main character Peter, she asks him what he'd like her to shapeshift into. His final request is [[ChubbyChaser Big flabby grandma arms/Bingo wings like a fat blue Britney Spears]] causing her to get incredibly fat and flabby, even changing into a much fatter actress. Could be a subversion as its the last thing we see of Mystique in the film, [[FanDisservice as it fades to black soon after he pulls her down and they start to get in on while she's fat, meaning she never changes back to her normal size.]]

* Whenever Wario eats the cake thrown by the Cook enemy in ''VideoGame/WarioLandII'', he turns into Fat Wario and is able to KO enemies by walking into them, break through certain blocks by jumping on them, and weigh down floating platforms.

** When Brutaka is infused with gaseous [[FantasticDrug antidermis]], it causes his muscles to grow, but the effect wears off after a short while. Later on, he absorbed liquid antidermis, and the effect to became permanent.

** Subverted in "Man Bear Pig" where Cartman stuffs himself on what he thinks is treasure (actually prop coins and jewels as part of a tourist attraction in the cave the boys are trapped in) so he can smuggle it out and keep it all to himself. He spends the rest of the episode realistically bloated from having eaten the fake coins, and heavier than usual (which proves a detriment when he demands Stand, Kyle and Kenny carry him to safety).

** Zarbon has been known to change from a skinny {{Bishounen}} to a fat, muscular, lizard monster when he fights. It should be noted that the latter form is actually his real one, but [[{{Narcissist}} he despises its hideous form]].
