* ''Fanfic/CalvinAndHobbesTheSeries'':
** Calvin's mother gets this in the end of "Camping Trip Part 2" after eating for quite a while.
** Hobbes gains one after eating a whole lot of fish in his segment of [[VignetteEpisode "Tales of a Tiger".]]
** Mother Brainstorm, BigEater as she is, gains one of these in "Forecast for Disaster" after demolishing an entire buffet.
* Several Phineas & Ferb fanfics contain these.
** Candace gets a particularly explosive one in [[http://www.fanfiction.net/s/7687457/1/Grilled_Cheese_Nightmare Grilled Cheese Nightmare]].
---> Candace (groans): This must be what it feels like to be pregnant.
** Candace's medieval counterpart, Candavere, along with her friends Stacehilda and Jenavene, gain some nice bulges after a large banquet at the end of [[http://www.fanfiction.net/s/8051818/1/Excaliferb_A_Further_Adventure Excaliferb: A Further Adventure]].
** In [[http://m.fanfiction.net/s/8238326/1/Two-Lads-in-Dangrabah Two Lads in Dangrabah]], Candace swallows a submarine sandwich whole, which causes her stomach to bulge out significantly. Because in this story, she is a genie, she uses magic to shift the fat in her gut into [[HartmanHips other places]], but since she doesn't do this immediately, it appears that she doesn't seem to mind being bigger.
** This is the plot of [[http://m.fanfiction.net/s/9463673/1/Queen-Sized-Candace Queen-Sized Candace]], after said character spends a week indulging herself in several desserts, the first meal resulting in DinnerDeformation (which resolves itself after said meal also gives her [[HiccupHijinks the hiccups]]). Later, Stacy and Jenny also get the same treatment.
** There is in fact fanart of some of these fanfics, such as the ones [[http://hellboy99.deviantart.com/gallery/34556517#/d4xc0y2 here]] and [[http://hellboy99.deviantart.com/gallery/34556517#/d4xl6ba here]].
* The InvaderZim fanfic [[http://m.fanfiction.net/s/9532539/1/ Feast of Doom]] so far has Zim being fattened up to enormousness for an ally planet's Moon Festival. So much so that GIR gets lost in his rolls of fat.
---> '''GIR:''' I just had the most wonderful adventure...
* SonicTheHedgehog's Rouge the Bat ends up fattening herself up in [[http://z7.invisionfree.com/Too_Fat_To_Fit/index.php?showtopic=145 Rouge's Weighty Frustrations]]. She doesn't even notice her weight gain for quite some time, until moments before she decides to go on a heist, where her fat stomach ends up getting her stuck in a small space... ''twice''.
---> '''Rouge:''' Well, this’ll be a red-letter day for the press, won’t it? 'Former Grand Thief, Rouge the Bat, Caught in the Act, Trapped by Her Own Weight'…
* This happens to Dawn in the second chapter of the [[TotalDramaIsland Total Drama]] fanfiction, [[http://totaldramaprison.deviantart.com/art/Total-Drama-Prison-Episode-2-377153946 Total Drama Prison]]. She drinks four whole bottles of aged soda as part of a challenge. Not only does her stomach bloat up and start aching, which lasts for the rest of the chapter, but she also gets [[HiccupHijinks the hiccups]] from drinking too much.
* ScoobyDoo's Daphne Blake purposefully gains weight in [[http://www.animexpansion.com/Stories/DoubleL/OutwittingAWideWraith.htm Outfitting A Wide Wraith]], in order to participate in a BigBeautifulWoman competition. Obviously, many jokes are made at her expense, but Daphne seems to be proud of her new figure.
---> '''Daphne:''' I don't know how you and Scooby ride in the back all the time, Shaggy. All that shaking made me feel like jello…
* Another example of a story revolving around this trope is [[http://m.fanfiction.net/s/366285/1/ A Pokémon Gaining Adventure]]. There are quite a few people who gain weight, but the story mostly revolves around Misty.
* [[http://browse.deviantart.com/?qh=§ion=&global=1&q=jessica+rabbit+belly#/d2mdij1 Jessica Rabbit Packs on The Pounds]] is pretty much ExactlyWhatItSaysOnTheTin. Jessica, tired of [[GagBoobs her breasts getting all of the attention]], goes to a sketch artist to draw her food that she immediately devours until she becomes [[FatAndProud extremely obese]].
* A {{Naruto}} fanfiction called "[[http://m.fanfiction.net/s/5134762/1/ Sakura, Hinata and the Buffet]]" has Sakura fatten up Hinata after both characters end up in a lesbian relationship.
* ''[[http://www.fanfiction.net/s/5855349/1/Global-Inflation Global Inflation]]'' has this happen to pretty much all the leads of ''AxisPowersHetalia'', as a result of massive inflation in all of their economies.
* In a SailorMoon fic, ''Fanfic/CosmicWarriors'', Naru and Usagi notice several customers have this when they arrive at a pancake shop.
* ''[[{{Fanfic/PlasmasFolly}} Plasma's Folly]]'' contains a non-comedic example: assuming his Zekrom form, a famished Ben swiftly devours a platter of food, swallowing whatever he can fit down his throat whole. This is good and fine, until he reverts to his human shape while retaining the contents of his stomach. Nearly leads to {{Death by Gluttony}}.
* Happens twice in ''Fanfic/TheLionKingAdventures'':
** Simba is fattened up by King Hapana in ''Desperate Measures'', causing his belly to grow three times its normal size.
** Haiba eats ''way'' too much in ''Changes'', thus creating his obese alter ego: Don Haiba.
