Some people and creatures can use their stomach to keep stuff within, sometimes [[BagOfHolding more than would comfortably fit in there]]. (Of course, it helps if they can gag it all back up when necessary.) Handy and unlikely to be found by frisking, if quite disgusting.

The acidic action of digestive juices rarely come into play.

[[folder:{{Anime}} and {{Manga}}]]
* Koumori, the first of the Maniwa Ninja from ''LightNovel/{{Katanagatari}}'', seemed to specialize in this.
* In ''Anime/CowboyBebop'', Spike does this. He swallows a cigarette when told there's no smoking in that area, then burps it up later. He repeats the process with a poker chip in the same episode.
* ''Manga/{{Bleach}}'': Dondochakka Birstanne
* In ''Manga/FullmetalAlchemist'', Kimblee stored a Philosopher's stone either in his stomach or his mouth when he was in prison (though probably not at all times).
** It's implied he's kept two at once in his stomach on occasion.
** Gluttony has an entire ''dimension'' in there. However, it isn't filled with digestive juices - it's filled with an ocean of [[{{Squick}} human blood]].
* ''Manga/{{Naruto}}'' has several examples:
** Orochimaru stores his sword, Kusanagi, inside his throat in reference to the Kusanagi of Japanese mythology which came from {{Orochi}}'s body.
** When giving a report on the enemy, Kisame coughed up a scroll with the information on it before giving it to a summon shark.
** Kinkaku is shown to store a special sword and fan inside of his stomach.
** Possibly Gerotora entering the [[SealedEvilInACan seal for the 9-tails]] by having Naruto swallow him whole (with some assistance) and/or Itachi having him swallow a crow [[spoiler:containing Shisui's other eye.]]
** Jiraiya can travel incognito inside a toad using this. [[BiggerOnTheInside The toad need not be giant enough to fit him in.]]
* The main character from ''Manga/BladeOfTheImmortal'' hid a scalpel in his throat and used it later to escape from a prison.
* In ''Manga/DragonBall'', King Piccolo swallows his dragon balls to prevent them from being stolen. His reincarnation Piccolo Junior does the same for the small jar he traps Kami in.
* The messenger spirit in ''Manga/OmamoriHimari'' keeps whatever she's delivering in her stomach, including a massive assortment of weaponry. [[VomitDiscretionShot Retrieving the items she carries is implied to be rather messy.]]
* Apparently this is something youkai in ''Manga/YuYuHakusho''-[[TheVerse verse]] can do to hide things, even from scrying attempts, but it's never elaborated on.

[[folder:ComicBooks]]
* In one ''ComicStrip/KnightsOfTheDinnerTable'' storyline, Brian declares that he still has his teleportation ring in prison because he regularly swallows and [[{{Squick}} retrieves]] it. He has this routine [[CrazyPrepared noted on his character sheet]], so B.A. can't accuse him of making it up on the spot.
[[/folder]]

[[folder:{{Film}}]]
* In ''Film/TheIncredibleHulk'', Bruce swallows a USB drive just before one of General Ross's attacks makes him HulkOut. Later, after he's reverted to normal, we hear him in the bathroom of the motel [[VomitDiscretionShot "retrieving" the device]], shall we say.
* In ''Film/TheHotRock'', during the gang's attempt to rob the diamond for their client Dr. Amusa, member Greenberg swallows it before he's caught by the guards. During a brief stint in a city jail, it passes through his system and he stows it in the cell, now out of their reach.
-->'''Dr. Amusa''': Couldn't you have just...kept ''swallowing'' it?
-->'''Greenberg''': [queasily]...no.

[[folder:Literature]]
* A thief in ''[[SherlockHolmes The Adventure of the Blue Carbuncle]]'' feeds a stolen gemstone to a goose so he can smuggle it home, intending to carve up the bird for dinner and retrieve the gem from its crop.
* In the ''Discworld'' novel "Sourcery", Rincewind meets a thief who stole some jewels taken by the leader of the Thieves' Guild. The interesting part? The leader had swallowed the jewels at the time. So, the leader knew full well who stole them, since only that thief was THAT good.
* In the novel ''DestroyerOfWorlds'', when a Pak is taken prisoner, it hides one of its devices from a search by swallowing the device. When it retrieves the device later, the device's surface is pitted and slightly damaged from the stomach acids. However, the device functions. Nonetheless, the Pak believes it will not survive another trip through its stomach.

[[folder:LiveActionTV]]
* In the ''Series/StarTrekDeepSpaceNine'' episode "Who Mourns for Morn?", it is revealed that [[spoiler:Morn took part in a bank robbery]] several years ago. He extracted the liquid latinum from the [[WorthlessYellowRocks gold casings]] and stored it in one of his redundant stomachs. Quark assumes this is why his hair fell out.
* In ''Series/{{Farscape}}'' Rygel once swallowed a control crystal that Moya needed. And in the miniseries he retrieved the crystallized pieces of Crichton and Aeryn from the sea floor by swallowing them and regurgitating them on the surface, unfortunately their unborn child reformed [[MisterSeahorse inside him]] and had to stay there for a while.
[[/folder]]

[[folder:OralTradition]]
* In the Hungarian folktale "The Little Rooster and the Turkish Sultan", the rooster has a magic stomach like this, which he uses to great effect: he can swallow and regurgitate everything from a well's entire water supply to '''''a swarm of hornets'''''. And since this is a children's tale, he does the latter without killing the insects; instead, he uses them as a ''GroinAttack BreathWeapon'' against the Sultan - [[CrowningMomentOfFunny no, we're not making this up]]!
[[/folder]]

[[folder:TabletopGames]]
* ''DungeonsAndDragons'': Second Edition Dark Nagas can swallow objects to spit out later, using a bag-like internal organ to carry things. The organ has thick, rubbery walls that protect the naga against pointed and sharp objects, protect the cargo against digestive juices and prevent magic items in the cargo from being detected.
** There is also an inversion an item that looks like a bag of holding but actually leads to the maw of an extra-dimensional creature.
* This is one of many possible powers for a chaos familiar which an evil wizard in ''TabletopGame/{{Warhammer}}'' can obtain.
* ''TheWorldOfDarkness: Inferno'' has this as a Gluttony Vestment for the Possessed, as a side use of a SwallowedWhole power. It explicitly states that the Possessed surpresses their stomach acids while using the power (and it's ''really'' uncomfortable). There's another power that allows them to regurgitate the item completely undamaged; said power's main use is acid vomit.
** There's also a Bone Gnawer gift in at least the original version of ''TabletopGame/WerewolfTheApocalypse'' which allows this (here, the "stomach" it sends swallowed items to technically exists in [[{{Hammerspace}} the Umbra]]). Thematically appropriate to the Gnawers' role as the "scavenger" tribe among the Garou.

[[folder:VideoGames]]
* The bomb bags in ''TheLegendOfZelda'' are made from Dodongos stomachs.
* VideoGame/{{Kirby}} has this in ''Squeak Squad'', allowing him to store various powers or recovery items, among others.
* ''Franchise/FinalFantasy'': The [[http://finalfantasy.wikia.com/wiki/Fat_Chocobo Fat Chocobo]] first does this in ''[[VideoGame/FinalFantasyIII III]]'' and does it again in ''[[VideoGame/FinalFantasyIV IV]]''.
* This was where {{Tomba}}'s inventory was located, he even was able to keep live animals in there.
* Klaymen of ''VideoGame/TheNeverhood'' stores items in a cabinet-like space in his torso, complete with a door.
* In ''VideoGame/MetalGearSolid'', Solid Snake smuggles a pack of cigarettes to use on his mission. When asked about how he managed to do that (considering he's been thoroughly searched prior to his departure), he replies: "In my stomach." Justified in that he explains he could only do this because he was given a shot that suppressed his stomach acid.
** That's a clever idea and all, but that doesn't exactly explain... ''how'' this was accomplished. I mean, the item shows it's got a whole box. And which end did this come back out of? I don't particularly like the idea of Snake throwing up individual soggy cigarettes at the dock. Nor do I like the idea of him forcibly hurling an entire box.
** '''[[WebAnimation/AwesomeSeries I'M GONNA USE THE CIGARETTES I HID IN MY STOMACH!!! AWESOME!!!]]'''
* In ''VideoGame/{{Rayman 2}}'', Globox and his children store useful items for Rayman inside their body.
* The "Spike" enemies from the ''SuperMarioBros'' series regurgitate spiked balls into their hands and then toss them at you.
[[/folder]]

* Ace Dick, from ''ProblemSleuth'', can use his stomach as an additional [[InventoryManagementPuzzle inventory slot]] (and even has a "stomach capacity" statistic that rises as he levels up).
* ''Webcomic/SchlockMercenary'': Sergeant Schlock tends to store his [[HandCannon plasgun]] in there.
[[/folder]]

[[folder:WebOriginal]]
* The ''Wiki/SCPFoundation'' gives us a strain of the flu that allows you to regurgitate anything useful at the moment. The items take mass from your body and there are mutations that result in either harmful substances or different exit points.

[[folder:WesternAnimation]]
* ''WesternAnimation/EdEddNEddy'': Ed's apparently works like a storage facility or refrigerator sometimes.
* {{Chowder}} often stores things in his stomach. Even things that could not possibly fit there.
* Rico from ''ThePenguinsOfMadagascar''. As well as 'small' things like lit dynamite, bombs, bowling pins, and a running chainsaw, it is also revealed that he has an elevator and a spiral staircase for getting to the bottom. His stomach can safely hold Mort too. He once choked up an ground-to-air missile and launching platform.
** In "Roger Dodger", Roger the Alligator switches minds with Rico. Roger keeps coughing up dynamite and flamethrowers, showing that it's an ability of Rico's body, not of his mind, but only Rico can control what comes up.
* The title character of ''BountyHamster'' has Cheekpouches of Holding.
* ''WesternAnimation/FamilyGuy:'' Mayor Adam West keeps everything he needs in case he is ever held hostage in his stomach, such as an inflatable raft for escape purposes and a magazine for him to read in case his escape fails. He also has Stratego in case anyone wants to play.
* In an episode of ''WesternAnimation/SouthPark'', the boys are trapped in a cave after a cave-in. Cartman finds a huge stash of buried treasure, and over the course of a few days, swallows it all in order to smuggle it out without the other boys knowing. [[spoiler:He ends up [[DinnerDeformation a grossly misshapen human sack of treasure]] until he can't hold it in anymore and craps it all out at the end of the episode, after which the cave was revealed to have been an old tourist attraction, with the treasure being fake and made out of plastic.]]
* In an episode of ''{{Jimmy Two-Shoes}}'', Jimmy coughs up a surfboard almost as big as he is.

* On a few occasions in ''WesternAnimation/{{Animaniacs}}'' Yakko and Dot have retrieved things from Wakko's stomach.
* ''Dora The Explorer'': Dora's Backpack, hence her {{catchphrase}}, "Yum, Yum, Yum, Yum, Yum! Delicioso!".
* In ''WesternAnimation/BatmanTheBraveAndTheBold,'' ComicBook/PlasticMan is able to do this, presumably because [[ExactlyWhatItSaysOnTheTin his body is plastic]] and thus not as damaged by swallowing a bunch of gold coins. [[KleptomaniacHero And it's usually gold coins he's swallowing]].
* One old Halloween episode featuring DonaldDuck has him swallowing a key leading to his treats. Unfortunately for him, the person he vexed was a witch. Naturaly, she uses magic to force his body to kick it out. HilarityEnsues.

[[folder:RealLife]]
* Drug runners who swallow tightly wrapped packets of cocaine or heroin to get them past customs, with a real risk of the packets rupturing and killing the runner with a massive overdose.
