"Now, now, I'm sure it's nothing to worry about... although such a rapid weight loss in such a short space of time is most unusual."
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 gain weight, lose weight
, grow muscles
, or 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.
Not to be confused with Incredible Shrinking Man
or Attack of the 50-Foot Whatever
. Compare Balloon Belly
. The Heavy Voice
is sometimes a side-effect of this trope.
Anime and Manga
- The innuendo-tastic mascot of UK price comparison site Confused.com had her weight rise by "37%" (actually more like 100% minimum) by magic in comparison to car insurance bills, making her pull out an exercising bike from her pocket and slim down to her normal size in two seconds flat.
- This advertisement for Malabar bubble gum features a woman who can inflate another woman's bottom by inflating her bubble gum, and so it temporarily inflates to very large proportions.
- The Miss Nelson/Viola Swamp books. How the heck did Miss Nelson drastically lose enough weight to play Miss Swamp and then go back to normal, again?
- In The She Hulk Diaries everyone wearing the cloths made by designer X (in reality the pranking villain nicknamed Super Brat) instantly becomes obese. Fortunately She Hulk is there to help removes the cloth's, which immediately reverts them to normal.
- That's So Raven had an episode about how too much junk food would make you fat. Raven's high school cafeteria is bought out by a fast food corporation who slowly introduce 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.
- One episode of Big Wolf on Campus has Merton go from thin to morbidly obese in a matter of days after befriending a group of women. It turns out they're actually Spider People who are intentionally fattening him up to eat.
- When Brutaka is infused with gaseous 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.
- In the Karda Nui arc, the light-energy emanating from the area boosted Takanuva's natural light-powers, causing him to grow considerably larger than his fellow heroes (to a $30 price-point titan-sized set, as opposed to the regular $13 canister sets). When he left Karda Nui, he shrunk back to his original size.
- 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.
- Ever-shallow Curtis briefly lost his crush on Michelle when she returned from France big enough to crush him. The next time we saw her, she was as svelte as before the trip.
- Similar to Roshi (as he's a Expy of him), Tung Fu Rue in Fatal Fury hulks out after losing a fourth of his health and becomes radically larger and more muscular. After getting knocked to one-fourth of his health, he shrinks back to normal. In later games, the trope is discarded, and Tung Fu Rue's "muscle" self is actually his Battle Aura.
- Queen Oren in The Legend of Zelda: A Link Between Worlds goes from a svelte fish woman to a giant Brawn Hilda when the Shady Guy steals the Smooth Stone from her fountain. At one point, she is shown immediately getting bigger upon gulping down a fish, and the other Zoras maintain that Link must get the stone back before she gets even bigger.

After struggling to lose weight for several strips, he's returned to normal size after alien robots who want to eliminate him because he's Walking Techbane shoot him with a disintegrator ray, but only manage to burn off the excess bulk.
- The fox in Tally Ho! 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 the end of his digestion felt horribly thorough.

- In The Fox Sister, the dog Soot Bull gorges himself on Alex's gift of leftover bulgogi, and for the rest of the day is much tubbier than usual. Yun Hee even comments on it.
- Rak Wraithraiser from Tower of God 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.
- Family Guy has at least three cases of this trope:
- The Simpsons also has a few cases of size changes:
- Pretty much any episode where Homer or another character pigs out and gets bloated from overeating.
- One episode had Homer gain weight (up to 300 lbs) on purpose in order to claim disability and work from home. When there was a fatal problem at the power plant, he literally plugs the problem (unintentionally) with his fat ass. The episode's end averts the trope somewhat by showing Mr. Burns deciding to give Homer liposuction (originally he planned to have Homer work himself back into shape, but got so annoyed by his slow progress that he decided to just pay for the liposuction).
- In another episode, Bart's school gets a soda/candy machine. Bart eats and drinks from it every single day until he gains a lot of weight. The episode parodies this by actually redoing the whole opening scene with Bart's bigger bulk.
- Homer once got his stomach stapled to slim himself down after Marge becomes a successful business woman and was afraid she would leave him. The rapid weight loss he underwent left him with extra skin which he had to clip up from the back.
- Another episode when Marge suffered from agoraphobia after being attacked by a mugger. Marge, living in the basement, starts working out with the equipment Homer bought and later becomes a bodybuilder and starts abusing steroids.
- In an episode of "The Itchy & Scratchy Show" Scratchy joins a gym and builds huge muscles by doing just three presses of a loaded weight bar.
- In the episode where Homer plays Everyman, he has to lose a lot of weight for the role, which he does easily, and ends up gaining all the weight back in what's probably just a few weeks.
- During Homers hunger strike she forces all her children to eat his massive share of food resulting in them all getting fat. When questioned by Lisa why she doesn't just cook less food instead she gives her daughter a deadpan look and flatly tells her she doesn't do things that way.
- On the episode "Suds", SpongeBob SquarePants 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.
- Sandy gains an enormous amount of weight in order to hibernate in "Survival of the Idiots".
- Eric Cartman once tried to bulk up with Weightgain 3000, thinking it would make him more muscular. He just ends up getting fatter still, until he is a thousand-pound blob of fat being interviewed by Geraldo Rivera.
- In "Jared Has Aides", the boys fatten up Butters with food from the local Chinese restaurant trying to follow Jared Fogle's fame. Butters gained enough weight to make a deal with the restaurant owner. Butters couldn't lose any weight, so the boys perform liposuction themselves.
- In an episode about World of Warcraft, the boys are grinding (leveling up through repeating easy tasks) by killing boars. As their characters spend lots of time being active and get more and more athletic and awesome, they spend all their time sat down eating junk and drinking soft drinks, getting fatter and fatter.
- And in "Tsst!" Cartman actually loses a lot of weight until he is only very slightly bigger than the other kids.
- Subverted in "Fat Camp" when it turns out the skinny kid that comes back from a weight loss camp is not really Cartman. He is very convincing, though, you'd guess that's exactly how Cartman would look if he really slimmed down that much.
- "Terrence and Phillip: Behind the Blow" shows that Terrence gained some weight after splitting from Phillip.
- Chowder often overeats himself into a huge ball, then deflates back to normal with one burp.
- There's also occasions where he's only slightly fatter than normal and in dire need of his emergency big boy shirt for one scene.
- In the Rocko's Modern Life episode "Tickled Pinky", after Heffer gets an emergency liposuction, he shrinks down to wire-thin size, but is back to normal next episode.
- Another episode when Spunky after eating too much grows steadily fatter until eventually his feet don't even touch the ground. At the end, he's given liposuction becoming slightly slimmer than usual. This episode focused more on Bloaty and Squirmy.
- Amy on 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 Swaps, 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 Fry and Leela making out in Farnsworth's and Zoidberg's bodies and lost their appetites.
- Henry and June on 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.
- On two separate occasions did Clover and Alex of Totally Spies! bulk up due to artificial methods (nanomachines and a serum, respectively). It seems that poor Sam was the only girl left out of the fun.
- Episodes featuring Sam always focused more on mental changes since she was the 'brainy' one of the three.
- In the episode "Passion Patties", both Clover and Jerry and a large number of other people got hooked on a mad scientist's super-addictive, super-fattening cookies, and wound up pretty big before getting turned back to normal.
- The scientist in charge herself became very fat in seconds after being force feed a direct dose of the formula she'd been putting into her cookies.
- In The Amazing Spiez, a character mutates to have a set very wide hips and bottom, but returns to her usual form by the end of the episode.
- In Scooby-Doo! and the Witch's Ghost Scooby and Shaggy overeat and as usual swell up their bellies. This time, however, they happened to meet three attractive girls and manage to suck in their stomachs to transform into bodybuilder physiques. The girls turn out to be the scary Hex Girls who frighten the two back into normal form. Ectomorph, Mesomorph, and Endomorph in a matter of seconds.
- This was the plot point of the Doug episode, "Doug Tips the Scales". The episode begins with Doug pigging out on junk food at his grandma's over the weekend, only for him to return home pretty chubby. After getting invited to a pool party, he works hard to lose all his weight, which he suceeds in doing. Though after going back to his original weight, he still complains about being fat, when all he really has is a slightly pudgy belly.
- Happens in the Direct-to-Video finale to Recess, Recess: Taking the Fifth Grade with Gus in the "Fifth and Sixth Graders Club" segment. Shortly after visiting the club for a week, the gang start to notice that Gus had been getting a little fat recently, as a result of eating too much. He remains this way until the next segement.
