->''"Great. We're inside a giant worm. What the hell are we gonna do now?"''
-->-- '''Damon Baird''', ''VideoGame/GearsOfWar 2''

Biologically based levels are pretty common, especially in ShootEmUp games. However, it's not always enough to explore a GreenHillZone or enjoy some JungleJapes - no, sometimes nothing will do but to have the whole level made out of meat.

And such a videogame level that takes place inside of a giant creature or otherwise huge organic structure is referred to as a Womb Level. Expect to see lots of blood pools, deadly digestive organs, climbable veins, deadly [[SpikesOfDoom bone spikes]], pulsating hearts, and floors, ceilings, and backdrops made of pink, squishy meat. Lots and lots of living, ''pulsating'' meat. [[NauseaFuel Yummy.]] Mysteriously, things tend to be relatively spacious, well-lit, and full of breathable air.

This is usually because the level is set inside some kind of [[AttackOfThe50FootWhatever Enormous]] EldritchAbomination of some kind, especially ones that like to [[JustEatHim swallow characters whole]], but sometimes it's just because the level designers felt like it. Also, because giant organs can be creepy, as can the very idea of being inside a living thing. As can the other sorts of [[ProportionatelyPonderousParasites organisms living inside the body]]. These qualities also make Womb Levels popular candidates for being TheVeryDefinitelyFinalDungeon, especially when it [[BloodyBowelsOfHell doubles as the game setting's Netherworld or Hell]].

If the outside of the creature involved is shown, expect it to be BiggerOnTheInside. Or maybe you were just shrunk.

The trope gets its name from a set of unfortunate side effects of the games they are in:

* If it's in a horizontally scrolling game, it tends to be a Tube Of Meat that you are flying through, and
* Far, far, too often, the boss of these levels is either a giant egg or an actual 2001-style Giant Space Fetus. [[labelnote:Note]]Heart and brain bosses are also overused though.[[/labelnote]]

If actual biological systems are invoked, expect all laws of anatomy to be cheerfully disregarded. Especially if it is a RibcageStomach.

Another version of this has [[MeatMoss alien bio-goo subvert and consume]] some previously normal technological structure. It may also be a LivingShip.

When not dealing with the alien bio-goo, this is similar to a FantasticVoyagePlot. The usual difference is tone and intent. A FantasticVoyagePlot is typically voluntary, and involves going into somebody's body to ''do'' something to it. A Womb Level rarely provides more than a different ambiance and setting for the same sort of experience that is otherwise typical.

In literature, Creator/MichaelMoorcock's Pulsating Cavern, in which Elric of Melnibone fights a quest (''see below'') , could well be the literal trope-namer and the genesis of many later imitators.

The polar opposite of EternalEngine. Compare MeatMoss, BloodyBowelsOfHell, OrganicTechnology, LivingStructureMonster and SwallowedWhole. If its already dead it's a GiantCorpseWorld.


!!Video Game examples:


* The penultimate level of ''VideoGame/{{Bleed}}'' is the strange digestive system of an immensely powerful dragon, culminating in a fight with its heart.
* The ''VideoGame/{{Contra}}'' games, starting with the arcade original, usually feature a womb level at the end of each game after the usual series of seemingly normal military bases and jungles. The few aversions of this trope are usually in games like ''Operation C'' and ''Contra: Hard Corps'', in which the {{Big Bad}}s are not actually aliens, but other humans who are using cloning technology to create alien-based weapons. The second arcade game's fourth stage has pulsating red and blue blood vessels along the walls.
* ''VideoGame/DevilMayCry'':
** ''3'' has a level in which you must "carve your way out of the Leviathan's womb", despite the fact it ''ate'' you. Given that the game names each room you enter (you start in "Leviathan's Stomach", for example), and ''none'' have anything to do with reproductive systems, one can assume they're being poetic. After you defeat Leviathan's Heart, [[spoiler:Dante makes his way through its body to the head and cuts his way out of the eye to start off the next level.]]
** In the first game the underworld has the appearance of the innards of a giant creature, but it isn't (hopefully).
** Fourth game has the inside of the Savior. Even though it's a ''statue'' (an enormous demonic statue, but still) the inside looks alarmingly organic.
* Level 12 of ''VideoGame/{{Evolva}}'' takes place mainly inside the Parasite's body.
* ''VideoGame/TheForceUnleashed'' features an Imperial base set around -- and ''inside'' -- a Sarlacc pit.
* ''[[VideoGame/GhostsNGoblins Super Ghouls 'n Ghosts]]'' put one in Level {{Four|IsDeath}}. Doubles as a GimmickLevel with the constantly changing gravity.
* ''VideoGame/GodOfWar'':
** One level of ''2'' has our sociopathic hero Kratos traveling in and around the Titan Atlas. Of course, seeing as he's made mostly out of rock and lava, it doesn't really ''feel'' like a Womb Level.
** In the original, Hades (the underworld, not the god) is composed mostly of spiked meat suspended mid air over a sea of blood.
** Though very short, Kratos also makes short ventures into fleshy environments in the first and third games. In the first, he must enter the dead hydra's mouth and walk to the boat captain to retrieve a key. In the third game, Cronos swallows Kratos in an attempt to finish off his grandson before realizing it's better to chew your food BEFORE swallowing.
* Another "whale" of an escape (and a case of GuideDangIt) is in ''VideoGame/KingsQuestIV''. Rosella has to escape a whale by climbing its tongue, and tickling it with a peacock feather.
* ''VideoGame/NinjaGaiden 2 (NES)'' The final stage is a gauntlet of challenging jumps and horrible enemy placement through a cavernous hall of flesh, beating hearts (among other raw, exposed organs) and more.
* Operation 007 of ''VideoGame/TheWonderful101'' involves the titular superhero team [[spoiler:being shrunken down to microscopic size and venturing into Prince Vorkken's body, in order to eliminate nanoviruses.]]

[[folder:Action Adventure]]
* The Playstation game ''VideoGame/{{Alundra 2}}'' featured a level inside the belly of a whale, only said whale had been turned into a cyborg due to the player's actions early in the game. Thus, while there were occasional organic elements, the majority of the level ended up looking more like an EternalEngine. Flint comes across many people [[SwallowedWhole who were swallowed up]] inside the enormous cetacean for many years [[GentleGiant before it became a demon whale]], and [[FateWorseThanDeath continue to remain trapped after the creature is restored back to normal]].
* In the second-to-last level of ''VideoGame/AmericanMcGeesAlice'' you discover that the huge, gently pulsing tentacles that stick out of the landscape here and there are actually part of the Queen's anatomy. Then you get to fight her inside her disturbingly organic castle, from which her "body" seems to extend. The sequel ''[[VideoGame/AliceMadnessReturns Madness Returns]]'' allows you to return to a more putrefying version of it to visit the Queen of Hearts again.
* The indy game ''VideoGame/{{Aquaria}}'' has not one but '''two''' womb levels. Both are unsettling enough to classify as {{Body Horror}}s, too. In comparison, being swallowed by a whale at another time is positively tame.
* The eighth area in both ''VideoGame/BlasterMaster'' and ''[[MissionPackSequel Enemy Below]]''. It's also home to both games' {{Big Bad}}s.
* ''VideoGame/CastlevaniaCurseOfDarkness''. The extra bosses are within the Cathedral, are the most evil beings in the game (even more than Dracula, bringing forth the question of why evil is in the CHURCH), and most of the lower levels leading to its lair seem to be made of flesh.
* ''VideoGame/CrusaderOfCenty'' has one, where you enter the innards of a monster making up a mountain range and eventually kill the monster by ''fighting her beating but otherwise unmoving heart'' in a boss battle. It's part of a running theme of "killing monsters willy-nilly is not a nice thing to do."
* The ''VideoGame/DantesInferno'' video game features Gluttony, which the creators of the game have described as like walking around in a giant stomach.
* The final level of ''VideoGame/EccoTheDolphin: Defender of the Future'' takes place inside the Foe queen, with the final boss being her heart, filled with acid blood.
* In the ''[[VideoGame/IceAge Ice Age: The Meltdown]]'' game, Scrat is eaten by Maelstrom (This did not happen in the movie). You start the level in the mouth, the enemies you face will be bacteria, you will encounter beating hearts in the digestive track for some reason. At the end of the level you face a parasite connected to what is presumed to be the anus. You have to throw pebbles at its eyeballs before time runs out in order to finish the level. Maelstrom will sneeze Scrat out after you beat this level.
* In ''VideoGame/LegacyOfKain: Soul Reaver'' in the second dungeon at the top of a giant citadel you have to wander into the "body" of your evolved brother, Zephon has become entangled with the actual building and you fight him inside... himself.
* ''VideoGame/LaMulana'' is a very, very tangential example: [[spoiler:the ruins, which you spend about 95% of the game inside of, are ''the body of the Mother''.]] More literally by the end, when [[spoiler:the Shrine of the Mother transforms into the True Shrine of the Mother: the entire area is reshaped by the appearance of massive protrusions of flesh and bone radiating out from the center...which, naturally, happens to be the final boss room.]] Also, a room in one of the pyramids features a diagram of the female reproductive system. The other pyramid has a counterpart room with sperm floating in the background. Yes, this is part of a puzzle.
* ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' and ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Ages]]'' have dungeons taking place inside the enormous Jabu-Jabu's belly. Also in ''Ocarina of Time'', the Great Deku Tree is a botanical variant.
* The Impact Crater at the end of ''VideoGame/MetroidPrime'' has suspiciously fleshy surfaces, and platforms in one room look like giant, misplaced teeth. Relatedly, the Leviathans in ''Videogame/MetroidPrime3Corruption'' are destroyed by crawling into their "mouths" and searching for a gigantic eye inside their bodies. Plus, a ship used late in the game has the cockpit INSIDE ITS BRAIN CAVITY, with eyes staring at you from all directions. Inside its head. [[spoiler:Phaaze later on is a [[GeniusLoci planet-sized]] Womb Level]].
* ''VideoGame/{{Okami}}'' does this ''twice''. Once in the stomach of the Emperor of Japan, another inside of a giant dragon. This trope is downplayed in the dragon level, as it turns out all that meddling with the dragon's internal organs ''does'' kill him.
* ''VideoGame/{{Prototype}}'' does this twice. At one point Karen Parker sends Alex into an Infected Hive to collect samples, where you fight [[spoiler: Captain Cross]], and later in the game he enters another hive, [[spoiler: chasing a leader hunter that's kidnapped his sister Dana, and using a Thermobaric Tank to break in. He ends up fighting the Supreme Hunter within.]] The outsides of the hives appear as buildings covered in disgusting fleshy red welts that occasionally spout out Hunters, but on the inside the walls are thickened with pulsing red and orange masses, and the floor seems merely damaged until [[spoiler: Hydras pop out]].
* In the second part of the first level of ''WesternAnimation/TheRenAndStimpyShow: Veediots!'', by the power of randomness (and taken from a scene from the episode the level was based on), Ren ends up in Stimpy's mouth, and must find his way through, avoiding nerve-endings and other hazards, fights a Tooth Beaver on the tongue, then must escape before the DescendingCeiling crushes him. And the final stage, "Marooned", takes place inside a giant monster that has swallowed Stimpy, based on the ending of the episode it was based on. The final boss is a slime monster. These examples are notoriously {{Squick}}, and both share the same creepy organ music.
* The fourth level of ''VideoGame/SpongeBobSquarePantsCreatureFromTheKrustyKrab'' is set in the stomach of an Alaskan Bullworm (partially based on a scene from the episode the worm came from). ''Supersponge'' also has one (set inside a prehistoric whale), and also has a giant worm for a boss (it's a tapeworm, though).
* One of the chapters in ''VideoGame/StarTropics'' consists of being swallowed by a whale and, like the ''VideoGame/KingdomHearts'' example below, navigating an [[MalevolentArchitecture anatomically improbable labyrinth]].
* The last two levels of ''VideoGame/TombRaider'' take place inside the Great Pyramid of Atlantis, which appears to be sentient and has walls covered in pulsating flesh and veins.

[[folder:Adventure Game]]
* The final area of ''[[VideoGame/BeneathASteelSky Beneath a Steel Sky]]'' is an underground complex being overrun with a biological computer that has absorbed [[spoiler: the protagonist's father]].
* The final episode of ''[[VideoGame/SamAndMaxFreelancePolice Sam & Max: The Devil's Playhouse]]'' takes place inside the body of [[spoiler:monster]] Max, though the inside of his body is a lot less "flesh and bone" and more "kitschy 50's household".
* ''VideoGame/SpaceQuestVIRogerWilcoInTheSpinalFrontier'' has a large portion of the game which takes place within the body of Roger's latest crush, Stellar. Roger himself lampshades the ickiness of the situation by refusing when the player tries to make him go into the lower intestine.
* ''VideoGame/TalesOfMonkeyIsland Chapter 3: Lair of the Leviathan'' is almost 2/3 [[TropeNamer Womb Level]], [[spoiler:spent inside the belly of the giant manatee that Guybrush and the entire Screaming Narwhal were swallowed by at the end of Chapter 2.]]


[[folder:Beat Em Up]]
* The aptly named Organica in ''VideoGame/AlteredBeast: Guardian of the Realms'' walks a fine line between JungleJapes and [[TropeNamer Womb Level]], consisting of a pulsating landscape enclosed inside what's either a forest canopy or living cavern, populated by {{Man Eating Plant}}s and BigCreepyCrawlies.
* In ''VideoGame/CastleCrashers'', the blacksmith stores your weapons in some sort of living creature with its mouth wide open. It's a weapon frog.
* ''VideoGame/{{Splatterhouse}}'' has the womb level which is the hardest level in the game (harder than {{Hell}}, even).
* ''WesternAnimation/XiaolinShowdown'''s [=PS2=] video game has ''three'' womb levels - Dojo's Mouth, Dojo's Esophagus and Dojo's Stomach.
* The alien part in ''[[VideoGame/StreetsOfRage Streets of Rage 2]]'' feels like something like this, had it not been an amusement park attraction. However, it definitely has the feel and look of a Womb Level. It looks like something from the ''VideoGame/{{Contra}}'' series, actually.

* The various ''Anime/DragonBallZ'' series all have a stage set inside Super Buu, ripped straight from the show.
* Pictured above, the final battle against Jedah in ''VideoGame/{{Darkstalkers}} 3'' takes place in [[http://1.bp.blogspot.com/-KJPHOAKOzfg/TYusWqvhLFI/AAAAAAAAAWY/CrwmNlE6Eyw/s1600/Fetus%2Bof%2BGod.png a giant womb]], complete with the giant fetus of a dark god in the background. It is appropriately named "Fetus of God" ("Creator's Fetus" in the English version of the PSP re-release).
* Jiraiya from ''Manga/{{Naruto}}'' can summon the stomach of a cave toad to change the environment to this in battle.
* ''VideoGame/{{Skullgirls}}'' added a stage called Gehenna which consists of pulsating, fleshy blobs, a lake of blood, and numerous eyes and teeth in the background complete with a near music-less soundtrack.
* [[TrueFinalBoss Master Core]] of the UsefulNotes/WiiU version of ''VideoGame/SuperSmashBros'' becomes one of these as Master Fortress. It's a gargantuan landmass covered in flesh, has {{Acid Pool}}s and is protected by shadowy versions of pre-existing enemies. The player must go through a ColossusClimb inside Master Fortress to take out its glowing weak points to defeat it. The layout even resembles a digestive tract and as the player approaches one of its weak points a heartbeat sound is added to the soundtrack.
* In the PC fighting game ''VideoGame/{{Xenocide}}'', Parasite's stage (presumably his home "world") is made up of raw flesh, with toothy mouths in the walls.

[[folder:First Person Shooter]]
* When playing as the Alien in ''VideoGame/AlienVsPredator 2'', you have to bite your way out of your first victim's chest.
* With all the talk of Glomar being a creature and its "heart" traveling through "veins," ''VideoGame/AlphaPrime'' heavily implies it will end this way, but it turns out that they are just euphemisms after all (for the most part).
* ''VideoGame/{{Blood}}'':
** The second-to-last level "[[ExactWords In the Flesh]]" takes place inside a monster . Its elevator-and-switch-based biology allows it to stay alive for centuries, feeding only on zombies, gargoyles and robed cultists.
** "House of Horrors", the secret level of the first episode, is set in an evil funhouse within a CircusOfFear that is mostly made of living, ''breathing'' flesh.
* Several of the hellish sections in ''VideoGame/{{Doom}} 3'' are covered in living flesh.
* The Hive from ''VideoGame/DukeNukemForever''.
* ''VideoGame/{{Halo 3}}'' has its next-to-last level set inside what was formerly the Covenant city of High Charity, but is now fully engulfed by the Gravemind. Leaving you crawling inside what is essentially a city-sized mass of pulsating icky Flood guts, with only occasional peeks at the structure of the original High Charity, now serving as scaffolding for Gravemind's bulk.
* Much of ''VideoGame/Prey2006'' takes place inside what is effectively a giant biomechanical organism. With lots and lots of sphincters.
* The final battle in the ''VideoGame/{{Quake}}''-clone ''Chasm: The Rift'' was against a giant worm; the only way to beat it was to get swallowed by it and destroy its heart.
* While not technically inside a creature, the Strogg of ''VideoGame/QuakeIV'' (think Clive Barker meets the Borg) have a tendency to use biological material interchangeably with machines, and as such, one level contains a giant, mechanically augmented heart with a tesla coil for a pacemaker, and a hallway make of writhing intestines. In theory, the building itself is one enormous cyborg. Each time the tesla coil made the heart beat, this building would scream in pain.
* In ''VideoGame/SystemShock 2'', one of the final levels takes place inside the Many, a giant mass of flesh that has grown around the spaceship you're in. Along your journey through the biomass, you can find and listen to the recorded observations of a scientist who was dragged through it ahead of you.
* ''VideoGame/UnrealIITheAwakening'' features a planet that actually happens to be a gigantic living organism. The latter half of the level is spent inside it. It has giant hairs sticking out like freaky trees on the surface, and lots of teeth in a few places too. Oh, and little wiggly white things when you're inside that look a bit like they might be a physical representation of energy in it's nervous system. Understandably it's rather pissed off when you [[spoiler:blow part of it up with some demo charges to get a piece of the what-turns-out-to-be-an-ArtifactOfDoom, and tries to kill you with the equivalent of antibodies that are about as big as you are and attack by charging into you and exploding.]]

[[folder:Hack And Slash]]
* In ''{{VideoGame/Gauntlet}}: Dark Legacy'', the stage Your Worst Nightmare in the Dream Realm starts with the players going through a large disembodied mouth, and includes such features as a bits of giant ribcage and a giant beating heart among the squishy meat scenery.
* In ''VideoGame/LollipopChainsaw'', [[spoiler:Juliet is forced to go inside Killabilly's body in order to finish it off.]]
* ''VideoGame/MuramasaTheDemonBlade'' has Momohime and Jinkuro in an oni's belly at one point. Cue the buzzsaw technique to get out before you're killed by the stomach acid.

* One of the explorable areas, the Domain of Pain, near the end of ''VideoGame/GuildWars: Nightfall'' is this sort of level.
* In the MMO ''VideoGame/LaTale'', you have to annoy a giant worm-like monster (with teeth!) named the Behemoth in Orca Beach (Formerly Field Area) by trying to dig it up. If you succeed, it will swallow you, leading to a level full of germs, pukes, and blood cells in the form of humans in blood cell shaped vehicles. The boss of said area is Dr. Rice, the apparent leader of the blood cells and the one that controls the Behemoth, said person also plans to destroy Jienda using the Behemoth. The only way out is to find the uvula at the very end of the level and whack it with your weapon.
* ''VideoGame/WorldOfWarcraft'' gives us Nespirah, a shellfish goddess the size of a city. Despite looking creepy as hell, she's actually on your side; the Naga have her mentally subdued as they steal her pearls, and players are tasked with saving her. There are three other creatures like her in Vashj'ir. One of them has a Twilight Cult temple built at it's center, and another can't be saved and his wish is to die painlessly. Another Womb Level (though much smaller) is the Old God's stomach in the Twilight Highland. If you stay outside of the NPC's shields for too long, a green meter starts filling up and you start to be digested. The hives of the Silithid and most of the Temple of Ahn'Qiraj take place in disturbingly fleshy surroundings. And if that's not enough, during the final encounter with [[EldritchAbomination C'thun]] players will sometimes get swallowed and end up in his stomach.
* ''VideoGame/DungeonsAndDragonsOnline'' has the quest "Belly of the Beast", which takes place in the guts of a giant Purple Worm.
* ''VideoGame/FinalFantasyXIV'' combines this with elements of a BattleshipRaid with dungeon raids set inside Alexander. Like in other entries of the series, Alexander is presented as a massive walking mechanical fortress, but in the context of this game, is a primal; a manifestation of a beastman tribe's patron deity (in this case, the goblins). Unlike other primals, however, players don't fight Alexander in a boss battle, but instead fight their way through its body over the course of multiple dungeons.

[[folder:Platform Game]]
* ''VideoGame/AdventureIsland'':
** The FinalBoss of ''Adventure Island II'' can be found inside a dinosaur of Dinosaur Island.
** In ''Super Adventure Island'', Round 2-3 is an UnderTheSea swimming level that also happens to be inside a whale.
* The original ''VideoGame/ApeEscape'' had a level inside a dinosaur-like creature named Dexter. It was lampshaded, even if unintentionally, by a mailbox from Natalie/Natsumi telling you that Dexter had a 'complex labyrinth' inside his body - "don't get lost!"
* ''VideoGame/ArdyLightfoot'' contains a level in which you're swallowed by what can only be described as a HUGE... worm-thing, after beating one of the bosses, who also gets swallowed. You have to navigate through its body to get out, and find the body of the boss you just beat. It's scarier in the Japanese version, since you see her bones lying there. In the American version, the sprite was altered so we just see her lying there dead. It's even scarier when you look at the beta picture for what she was supposed to look like. The sprite isn't designed very well, but she was originally supposed to be in the middle of getting dissolved. You can see it on [[http://www.randomhoohaas.flyingomelette.com/shr/ardy/ this website]], although you'll have to scroll down quite a bit.
* ''VideoGame/BalloonKid'': Stage 3 ends with the player willingly walking into the open mouth of a surfaced whale. (If only the screen would scroll high enough to just float over it!) Stage 5 (after the whale-innards level) begins with EXITING a whale's mouth as well, meaning this is yet another case of a two-headed whale...
* Happens surprisingly often in the ''VideoGame/BanjoKazooie'' series, including Clanker the partially-mechanical shark and a giant turtle named Tanktup in the first game, as well as an overgrown fish and a "Chompasaurus" plagued with stomach ulcers in the second game.
* ''VideoGame/{{Bonk}}'' and ''Super Bonk'' did this. In ''Bonk's Adventure'' this happens when you're swallowed by a stegosaurus; in Super Bonk this happens when you're swallowed by a pterosaur that's ''[[FridgeLogic smaller than you]].'' Whereas most Womb Levels are sprawling areas containing elements of organs that aren't even part of the digestive process (sometimes to the extent that the creature is essentially hollow), here you go through a short swimming section composed of a smallish central chamber and a cramped, twisty passageway; literally just the stomach and bowels, as someone who was theoretically SwallowedWhole in real life would go.
* The first episode of ''VideoGame/CosmosCosmicAdventure'' ends with Cosmo being swallowed alive by a giant alien as a cliffhanger. The second level of the second episode takes place inside the alien (the first level is simply a rewind of the first episode's cliffhanger). In the third episode, Cosmo willingly enters inside another alien at the end of the first level, and explores it in the second.
* ''VideoGame/EarthwormJim'':
** The first game has the level [[http://www.youtube.com/watch?v=Y_qUEbpnhKU "Intestinal Distress"]], which takes place in a giant alien's intestines; and the boss is named Doc Duodenum. This level wasn't present in the SNES version.
** ''Earthworm Jim 2'', even the SNES version, follows this up with the [[http://www.youtube.com/watch?v=1vNOZjKWs6k "Villi People"]] level, which appears to be a giant set of intestines. According to the manual, it's actually a planet that ''looks'' like a giant set of intestines... and it's also Doc Duodenum's summer home (although the doctor does not appear).
* Levels six and seven of ''VideoGame/{{Flashback}}'' take place in the Morph homeworld.
* The deepest part of the Metal Head nest in ''VideoGame/JakIIRenegade''.
* It's not an organic creature, but the Destroyer from ''VideoGame/TheLegendOfSpyro: Dawn of the Dragon'' certainly counts. It's a gigantic rock monster so huge that it literally has a small city on its head, and to defeat it you fly down its throat and have to destroy its crystal heart while the lava that basically functions as its bodily fluids roils and sprays around you.
* ''VideoGame/JoeAndMac'':
** The inside of a TyrannosaurusRex's body as the final level, complete with a giant, realistic beating heart.
** The sequel (in Japan) ''Congo's Caper'' has a level where you fight the devil inside a ''T. Rex's'' body. While there's no still-beating heart to contend with, the player has to totally submerge in and swim through sickly-yellow digestive juices instead.
* The FinalBoss battle of ''[[VideoGame/KeioFlyingSquadron Keio Flying Squadron 2]]'' takes place in an area like this.
* ''VideoGame/KirbyStarAllies'' has this [[spoiler: for its final boss, Void Termina]]. Kirby and company must alternate between attacking it on the outside with the Star Allies Sparkler to knock off its head, then enter its body to attack its core on-foot. The appearance of its insides are a nod to Dark Star from Kirby 64, largely consisting of the same hexagonal cell-like tiles but considerably more organic in appearance, with the (initially) heart-like core being supported by fleshy, tendon-like structures [[spoiler: and the unconscious [[BigBad Hyness]] and his minions creepily strung up alongside it.]]
* The ''VideoGame/{{Klonoa}}'' series have a few examples of this.
** In ''Door to Phantomile'' (and its remake for the Wii, just simply titled "Klonoa"), the final boss is a giant slug/frog-like beast named Nahatomb that shoots enemies out the cannon-like hole on its back (perhaps a strangely-designed and placed anus?) that you must throw into your friends' cannons so they can blast him. Once they do, it eats you and everything else, so the second phase of the battle continues inside its body. Thankfully, the innards of Nahatomb look more like an EldritchLocation than an actual stomach.
** In ''Klonoa Advance 2: Dream Champ Tournament'', there is a level that appears to be inside a whale (complete with a RibcageStomach), but with platforms, doors, items, etc. for some reason.
* Every world in ''VideoGame/LocoRoco'' has you get swallowed by a giant beast at some point, with the goal being not too far from its...other end. [[spoiler:The final boss is also a womb level, though this time you're actively trying to destroy parts of the body you're inside.]]
* The second half of the first world of ''VideoGame/McDonaldsTreasureLandAdventure'' first appears to take place inside a cave, but after Ronald goes inside, an eye opens from the outside, revealing the cave to be a giant monster. How Ronald gets out after defeating the world's boss (a giant tomato) to get to the next level is never shown.
* The third stage of ''VideoGame/MagicianLord'' is one of these.
* In ''VideoGame/MegaMan3'', from a certain point onward, Gemini Man's level has platforms and a background resembling cells, and features what appear to be fertilized eggs that block the player's way. When shot, they release what could only be tadpoles.
* ''VideoGame/MushroomKingdomFusion'' has a number of Womb Levels present: Corpse of the Behemoth, Lair of the Leviathan, and the as of yet unfinished The Castle of Meat.
* Played for cuteness in ''VideoGame/TheNewZealandStory'', where the main character is swallowed into the belly of an ice whale and had to beat up on a cutesy uvula to escape.
* In the ''WesternAnimation/PhineasAndFerbTheMovieAcrossThe2ndDimension'' video game for Wii and Playstation Move, there is a boss battle where the giant hairy monster that Phineas and Ferb faced earlier in the movie comes back. If it eats you, you have to use the Sticky Gloves to climb up the esophagus, grab the uvula, and then shake the remote for it to spit you out.
* The LicensedGame of ''Disney/{{Pinocchio}}'' has the requisite level inside Monstro the Whale.
* ''VideoGame/RadicalRex'' has the Innerworks level, which takes place inside a large brontosaurus. Here, you must get past amoebas, leeches, weird ghost-birds, and pits of acid that dissolve you instantly. On higher difficulties, there are also ''[[GettingCrapPastTheRadar sperm and egg]]'' enemies.
* ''VideoGame/RaymanOrigins'' has a level where you are swallowed by an overweight, gigantic dragon chef. As you traverse its insides, you encounter green, slimy fire-breathing monsters wielding toilet plungers ([[AllThereInTheManual These are apparently germs that live in his body]]). Once you reach the stomach, you have to avoid its heartburn (which is actually fire), avoid the gastric acid below and keep punching the pink bumps in order to gain access to the intestines. Then, you get chased by a stream of fire as you run ''up'' the intestines, which go ''[[{{Squick}} out through its mouth!]]'' Afterwards, the dragon shrinks back to his tiny and innocent self, burps, and remarks, "Thanks, I feel better now!" then says something in Italian. Despite Rayman being a cartoonish and family-friendly series, all the footage of the dragon's anatomy is quite realistic (you can see his pulsating arteries, blood cells swimming through his blood in the background, a realistic beating heart, etc) and complete with tissue, red colouration, and squelching noises as the heroes run across his innards.
* [[spoiler: The section after Wily Capsule Boss Fight]] in ''VideoGame/Rockman4MinusInfinity'' is on based the [[spoiler: organic final level]] of ''VideoGame/{{Gradius}} 2''. [[spoiler: It even has organic, blob-like versions of various Mega Man mooks. It is all an illusion.]]
* In ''VideoGame/ScurgeHive'' (for DS and GBA), there are more Womb Levels than can be safely counted. In fact, nearly every level is at least partially a Womb Level. Considering the game has you attacking an [[TheVirus infectuous biomass]], it's not too much a surprise. Of course, unlike most Womb Levels, actually stepping on or standing in the squishy red/pink stuff is actually pretty bad since the stuff is trying to constantly infect you as well. (Though you can jump like crazy and have almost no effect.)
* The second half of level 3 in ''VideoGame/{{Shinobi}} III''.
* The entirety of ''Slime-San'': The title character is swallowed by a giant worm (and in some DLC, a giant kraken) and must platform through a variety of fleshy tunnels and fight bosses that wouldn't look out of place in ''Videogame/{{Abadox}}'' to escape digestion. There's also full-sized towns filled with survivors living inside the beast's body.
* Intestinal Problem in ''VideoGame/{{Something}}''. The lava could be seen as stomach acid. To make things worse, Metroids cling onto Mario, weigh him down, and steal his coins.
* A secret area in ''VideoGame/{{Spelunky}} HD'''s JungleJapes area is the intestines of gigantic worm, where you can unlock VideoGame/MeatBoy as a playable character or find a powerful weapon upgrade.
* The last stage of the Turtle Zone ''VideoGame/SuperMarioLand2SixGoldenCoins'' is inside a whale.
* ''VideoGame/SuperMonkeyBall 2'' has a level that takes place inside a giant whale, though the whale has apparently eaten all sorts of buildings and trees, so the level looks more like a city. One of the rare instances of a womb level being beautiful SceneryPorn.
* In ''VideoGame/SuperRobotnikLand'', the sixth world takes place inside the body of HUNGRYMAN, the boss of the fifth world, after HUNGRYMAN eats Robotnik.
* ''VideoGame/{{Tempo}}'' has a womb level as one of the first levels in the game. You start off inside the mouth of what appears to be some sort of white, fuzzy beast, and then once you go into its body, you encounter hearts which are literally heart-shaped (and there seem to be many of them) and walking cheeseburgers. Then, once the level is complete, you randomly fight a boxing glove.
* One level in the Goblin Attack expansion for ''VideoGame/{{Trine}} 2'' has the heroes get swallowed by a SandWorm. The result closely resembles most other Trine levels, except with more acid and significantly ickier art assets.
* ''VideoGame/WarioLandII'' for the Gameboy Color: In the last level of the game, "Steal the Syrup's Treasure" you enter a cave behind Captain Syrup's castle that has pink walls that resemble flesh and are covered in eyes, ears, noses, mouths, and sections of intestinal tract, complete with conveyor belts that look like intestines. For extra creepiness, there are also enemies from the game that are embedded in the stage's skin-like background that have a look of shock on their faces.
* ''VideoGame/YoshisIsland'' features Yellow Yoshi getting shrunken down and eaten by Prince Froggy, miniboss of World 3. The only way to damage him is to aim eggs from the Shy-Guys he eats at his uvula. Yoshi gets out through the back passage... and gives the camera a look of absolute shock as the boss dies.
* In ''VideoGame/ARobotNamedFight'', you normally defeat the FinalBoss and take home the win. However, if you complete enough runs, the Megabeast instead releases a blood-red tractor beam leading into it's insides filled with the same meaty monstrosities it spawns- ultimately leading to the TrueFinalBoss- the Megabeast Core.

[[folder:Puzzle Game]]
* The Kraken in Nitrome's ''Icebreaker''.
* Even something as innocent as ''VideoGame/{{Lemmings}}'' contains one level set where the lemmings walk on intestines and have to bash their way through bones. Even their building blocks are bloody-pink!
* Out of the many planets in ''VideoGame/{{Meteos}}'', the planet Globin (the name should be a giveaway) is shaped like a giant red blood cell, is actually a living organism and is populated by an alien race that behaves like blood cells, distributing nutrients and repelling invaders. The background music is composed of heart beats, heart murmurs and a magnified breathing sound, creating a very creepy effect.
* The puzzle game ''Super Gussun Oyoyo'' features one for its final ten (secret) levels, taking place inside a {{King Mook}}. Succeeding shows Gussun and/or Oyoyo escaping through the digestive tract (while not shown, the dialogue and sound effects hint at this) and being transformed into {{Talking Poo}}, unable to reunite with Emily, their female companion.
* There is no way you can die in the educational game ''Think Quick!''. If you get eaten by a Slime Worm, all that happens is that you have to escape from the Slime Worm Belly.

* ''VideoGame/TheBindingOfIsaac'' has a literal womb as a late-game floor, with either [[spoiler:Mom's Heart or It Lives (a fetal Isaac)]] as its guardian.
** The Afterbirth expansion gives a creepier spin on it, adding an alternate floor called Scarred Womb, and [[spoiler:a Blue Womb, containing a BonusBoss called Hush.]]
* The third mission of the titular dungeon in ''VideoGame/DarkestDungeon'', aplty named "Belly of the Beast", is one of these. The background and walls of are composed of undulating veins and organs, and most of the enemies are cysts, cell stalks, and polyps.
* ''Videogame/SunlessSea'': The underwater port of Nook is actually the digestive system of some unknown, lamprey-looking leviathan whose odd physiology makes the water inside it breathable. Someone tore up its throat to make a port, people occasionally dwell in its mansion-sized teeth, and each "section" within this port is simply another part of the beast's anatomy.

[[folder:Role Playing Game]]
* ''VideoGame/BreathOfFireII'' has one level that takes place in the body of a giant whale. (You have to hit its uvula in order to enter inside.) Interestingly enough, the whale becomes your CoolShip once you've finished the quest. In another level, the heroes are shrunk and then have to enter the body of an obese queen in order to defeat the "fatty demons" located inside of her. (Although this is more of a FantasticVoyagePlot). This particular WombLevel is actually [[ShownTheirWork fairly accurately modeled on a human heart]], down to featuring red and blue color schemes in the appropriate areas: several dead ends are even quite clearly the branching arteries leading to and from the lungs. (The [[FanTranslation fan translator]] was so impressed by the discovery that he broke his "no abbreviations" rule to fit "L. Atrium", "R. Atrium", "L. Ventricle" and "R. Ventricle" into the twelve lettters alloted for location names.)
* The penultimate battle against Lavos at the end of ''VideoGame/ChronoTrigger'' takes place within Lavos himself. Well, sorta. One could say that what everyone ''thought'' was Lavos was just an outer shell or armor. And thankfully the insides lack lots of fleshy meat.
* ''Franchise/DotHack'' has a number of dungeons which are entered via a creature's mouth and appear as if you are traveling inside a living being (granted, a living being with nonsensical anatomy).
* In ''VideoGame/DragonAgeOrigins'', the fight in the [[spoiler: Broodmother's lair resembles this. Understandable given that Broodmothers are where Darkspawn babies come from.]]
* The final dungeon of ''VideoGame/DragonQuestVII'' looked like this, for some inscrutable reason. Probably because its freaky hell.
* The last, eerie walk to the BigBad of ''VideoGame/EarthBound'' seems to take place on a large, pulsating optic nerve/brain... [[BuffySpeak thing]].
* ''VideoGame/EtrianOdyssey''[='=]s Claret Hollows has walls made of flesh and skulls, powerful cells as enemies, damage tiles that look like stomach acid, and the final boss is called the "heart of the labyrinth". Cool huh?
* ''Franchise/FinalFantasy'':
** Leviathan's stomach in ''VideoGame/FinalFantasyII''.
** Metaphysically, the Giant of Babil in ''VideoGame/FinalFantasyIV''. It's mechanical, but it is shaped like the human body, and the sections are named after parts of it.
** The true form of [[spoiler:Exdeath's castle]] in ''VideoGame/FinalFantasyV'' is like this.
** ''VideoGame/FinalFantasyVI'' had monster called Zone Eater that can eat your party one member at a time. If he manages to eat your entire party, you then get to explore a dungeon inside it. Something of a subversion, though, as its innards really... don't look different from any other cave dungeon you go through right down to the wooden bridges.
** The floating continent in ''VideoGame/FinalFantasyVI'' and Kefka's tower, while technically not womb levels, have a "womb" feel to them.
** ''VideoGame/FinalFantasyX'''s final battle takes place in a strange dimension located within the body of [[spoiler:Sin, the flying, mountain-sized monster that appears and destroys the world [[ViciousCycle every ten years or so]].]] Though it doesn't ''look'' like a Womb Level once you're inside.
* ''VideoGame/GrandiaII'' has the heroes battling the Pope deep in the bodily recesses of the giant demon Valmar, which is orbiting high above the Earth. Earlier, the gigantic Body of Valmar (Valmar was somewhat... in pieces at this point) is defeated by entering its monster-infested and strangely puzzle-filled insides and destroying its core.
* ''VideoGame/TheHalloweenHack'': The walk into the center of Dr. Andonauts's mind seems to take place on a remixed version of the Devil's Machine. Oh, and Varik's group get their sprites changed into the ''VideoGame/EarthBoundBeginnings'' counterparts.
* ''VideoGame/HellgateLondon'' has at least two Womb Levels -- one involving an Exospector, and the other somehow involving a portal to Hell through the Resident ButtMonkey's mind.
** The Exospectors are those giant floating whale-like things that could be seen over the city. It's believed they act as troop transports. [[spoiler:You get to run around inside of one after shooting it down. As part of a quest chain, someone asks you to go inside it and bring out whatever powers the accursed thing.]] This of course leads to pocket dimensions, as you cover enough winding tunnels to give the subways a run for their money, when it's shown that the downed Exospector can't be much bigger than a four-floor building, inside which the amount of ground covered would never fit.
** Inside aforementioned ButtMonkey's brain, you get to [[spoiler: fight his Id, Ego and Super-Ego in one of the most anti-climactic boss battles ever. It could have been awesome, but it just ends up as this chaotic brawl in a tiny squishy chamber. On the other hand, all three bitch constantly and voice said ButtMonkey's thoughts, notably saying ''"Want me to turn my back so you can stick a knife in and twist?!"'' several times during the fight.]] Poor bastard. Given he's assigned to one of the looniest lords means he ends up being the guinea pig for many of said loon's experiments.
* In ''VideoGame/HolyUmbrella'', Donderamaid sends the Mammoth Whale to swallow the Pickle Express. It turns out that an entire town exists inside the whale, as well as a sea of gastric acid and other areas.
* ''Franchise/KingdomHearts'':
** ''VideoGame/KingdomHeartsI'' has your Gummi Ship swallowed by Monstro, a SpaceWhale version of the whale from [[Franchise/DisneyAnimatedCanon Disney's]] ''Disney/{{Pinocchio}}''. Of course, if ''Kingdom Hearts'' is accurate in its whale anatomy, the sea creatures are actually filled with nothing but fluorescent purple stairs, glowing portals, radioactive pulsing polka dots, and lots of wooden barrels. Monstro reappears as a level in ''Chain of Memories'', and also in ''[[VideoGame/KingdomHearts3DDreamDropDistance 3D]]'', where it makes up the entirety of Riku's version of the Prankster's Paradise world. In ''[[VideoGame/KingdomHeartsBirthBySleep Birth by Sleep]] [[UpdatedRerelease Final Mix]]'' it shows up again, this time as a BonusBoss who swallows you at regular intervals.
** Two stages of the battle against the [[LivingShip World of Chaos]] take place (most likely) inside it. These rooms aren't squishy-looking themselves, but you do have to attack a disturbingly organic-looking node of some kind to get out.
* ''VideoGame/LandsOfLore II'' has a more literal instance of a WombLevel than most. The [[SufficientlyAdvancedAlien Ancient]] God Belial anticipated his own death, and created a "Mother Beast" - a truly enormous immobile biological monstrocity made for birthing smaller monstrocities - to guarantee his rebirth. Over the course of the game, it gestates and produces [[SortingAlgorithmOfEvil progressively less-and-less malformed versions of its creator]] as its worker-ant monstrocities bring it more fragments of Ancient magic, and is nearly done gestating the flaw-free incarnation at the end of the game. The last level has you traipsing around the [[MalevolentArchitecture fleshy chambers]] inside the Mother Beast (at least in this instance it's [[JustifiedTrope justified]] - the room- and corridor-like spaces were probably meant for use as such by the worker and soldier monstrocities milling around like the thing's body were an ant colony), the goal being to prevent Belial from incarnation with his whole power by finding the chamber with the evil god fetus and stuffing Ancient magic in him the wrong way to induce a miscarriage. The final boss is the miscarriage.
* ''VideoGame/LegendOfLegaia'' finished the game with a battle inside a giant Seru, which was really just an excuse for an AmazingTechnicolorBattlefield. Many of the levels before that had been semi-organic and Seru-made. And then there's Conkram -- imagine a [[CrystalSpiresAndTogas marble-and-gold kingdom]] making sweet unholy love to a WombLevel and baptizing the child in terror. And unlike the Bio Castle, it's been like this for ten years.
* In ''VideoGame/MakaMaka'', the party gets eaten by a fat princess appropriately named Gourmet, and they must escape from inside of her.
* ''Franchise/SuperMarioBros'':
** Not so much a level, but in ''VideoGame/PaperMario'' you fight some fuzzy caterpillar thing on the inside of a whale. And it's dark.
** ''VideoGame/MarioAndLuigiPartnersInTime'' has the Bros get eaten by a giant alien Yoshi known as Yoob. They also get out through the back passage.
** In ''VideoGame/MarioAndLuigiSuperstarSaga'', [[spoiler:Cackletta's soul]] is fought inside Bowser's stomach.
** ''VideoGame/MarioAndLuigiBowsersInsideStory'' is initially this until Bowser is awakened, at which point it becomes a FantasticVoyagePlot.
* Played with in ''VideoGame/MassEffect2'' during the [[spoiler: attack on the Collector base]]. Not only is the base highly organic and filled with any number of analogues for natural defenses in a living being, but [[spoiler: it becomes a literal womb level when you face the final boss, a giant Reaper embryo]].
* Although it's not a literal one with flesh and all, the island, the temple on it, and the final dungeon of the game (behind a certain door within the temple itself no less) in ''VideoGame/MysticArk'' can be metaphorically be described as such. Just watch the ending and figure it out.
* When engulfed in ''VideoGame/NetHack'' you well be taken into a one space area with the walls being the enemy who engulfed you.
* ''VideoGame/NiNoKuni'' has Mummy's Tummy, a dungeon inside the literal womb of the literal mother of all faeries. It's... possibly the most bright and cheery example of this in existance, given that her innards also seem to double as a ''preschool'' for the baby faeries and have all features you might expect from such a place, like a playground and colorful murals on the walls.
* ''VideoGame/OracleOfTao'' has a section inside a CosmicEgg [[spoiler: responsible for existence]], so it's literally a WombLevel.
* ''VideoGame/PaladinsQuest'' has a cave dungeon called Dragon Mountain filled with monsters with names like Virus and Parasite. When the characters exit on the other side, the "mountain" reveals that it was alive after all and that the characters have just crawled out of its ''mouth''. Guess what the entrance really was.
* ''VideoGame/PhantasyStarIV'' has the Garuberk Tower, which is more or less a giant pillar of organs, veins, and ''eyes'', which [[TheHero Chaz]] has to interact with in a nonspecific way in order to make the fleshy walls tremble and make new areas accessible. The truly unsettling about it is that the Tower isn't a creature-- it's just a huge tumor rising up out of the earth, existing solely as a power base for Dark Force.
* ''VideoGame/PhantasyStarOnline'' features Ruins 3, which is basically the insides of Dark Falz.
* In the VideoGame/GoldBox game ''Pools of Darkness'', you at one point end up on the gigantic, comatose body of the ex-god Moander. In order to complete the events there, you have to enter his body. Not only do you have to fight both enemy cultists and various immune-system baddies, but travel is done mostly through blood vessels, and Moander's heart still beats now and then, resulting in some VERY {{squick}}y tides. The BBEG of the area hides in the heart, and will happily stab it whenever you approach, flushing you out again.
* Minor one from ''VideoGame/QueensCrown'' the iOS game: after beating the final boss for the first time, [=NPCs=] with gateways in their bodies appear. The gateways inside them lead to a regular looking dungeon... with regular looking mooks... THAT SURPASS THE MAIN CHARACTER'S MAXIMUM LEVEL BY HUNDREDS. Use magic or die.
* The Final Dungeon of ''VideoGame/RomancingSaGa'': [[http://www.youtube.com/watch?v=49j29AHXUE0 Quietus]] is one large WombLevel, it is especially disturbing near the final chamber where there is a giant [[http://www.youtube.com/watch?v=nt5O3xHae_E pool of blood]] smack dab in the center of the passageway.
* In ''VideoGame/SaGa2'', the party shrinks to nano-size and enters the body of the human priestess Ki so that they can retrieve the MAGI inside her, which enemies are killing her to attain. Ki's body doesn't look disgusting like the typical WombLevel, but the party does have to battle her germs and phagocytes. And the music (in the DS remake) is ''creepy as shit.''
* Tanzer serves as this kind of dungeon in ''VideoGame/{{SaGa Frontier}}''. You are swallowed by him randomly.
* The final room of TheVeryDefinitelyFinalDungeon of ''VideoGame/ShinMegamiTenseiIf'' is a brain, complete with fetus final boss.
* Near the end of ''Videogame/SouthParkTheStickOfTruth'', you must enter Mr. Slave's ass in order to disarm a snuke inside of him as your character is the only one with both the knowledge of abortion and the ability to shrink via snorting Gnome Dust. Within said stage you can find various things such as used condoms, a phone and even Mr. Hat.
* ''VideoGame/TalesOfGraces'' has a short dungeon in the stomach of the Rockgagong, an enormous desert-dwelling monster. Although it looks like an ordinary cave flooded with purple liquid. The party contemplates taking the back entrance out, much to Cheria's disgust. Fortunately, it turns out the monster ''sneezes from its stomach'' so they get out with a bag of pepper another character had [[ItMayHelpYouOnYourQuest inexplicably given the protagonist earlier]].
* The final dungeon of ''VideoGame/TalesOfHearts'' takes place inside of Gardenia, the massive progenitor of the Zerom. [[spoiler: It's what was believed to be a black moon.]]
* ''VideoGame/ThroneOfDarkness'': The Meifumado Citadel starts out like any other castle encountered so far (except with creepy murals and much darker walls) then the room with the stairs up on the second level, is covered with flesh, and the stairs are made of bones. The next levels are all living, with pulsating walls, giant constructs of flesh and bone, and green steam coming from suspiciously anus-like holes in the ground.
* VideoGame/TormentTidesOfNumenera features The Bloom in the last third of the game which is a massive trans dimensional biomass with maws that devour it's residents but open portals to distant worlds.
* ''VideoGame/TreasureOfTheRudra'': The Heg. Add [[http://www.youtube.com/watch?v=7LqOuGkag_o very disturbing music]] and you have the stuff of horror. [[spoiler:Ruins of Meifa also counts too as the boss is fought in front of a giant heart and then fuses with it when you win]]
* At one point in ''VideoGame/WanderingHamster'', Bob gets eaten up by a giant snake, whose interiors feature alive seagulls, ducks and a complete ''mini-golf course''.
* ''VideoGame/WeirdAndUnfortunateThingsAreHappening'': Vedim Space. Red, with giant hands and mouths being part of the environment, and places made to look like faces.
* ''VideoGame/{{Xenosaga}}'': A good portion takes place inside the Cathedral, a planet sized Gnosis that also doubles as a mothership for their kind. Fortunately, there's not a lot in the way of blood and guts since somehow the aliens are made up of salt.
* At one point in ''VideoGame/{{Xenoblade}}'', you briefly travel through the inside of the Bionis, which serves as a reminder that the world you're exploring was once a living, organic being. [[spoiler: You eventually explore the location as a proper dungeon after the Bionis has awakened from its slumber. Things are more lively at that point, with the glow of the surroundings being much brighter, blood cells drifting through the air, and you now having to fight off both its literal and figurative immune system in the form of super-sized microbes and the alien Telethia respectively.]]
* In ''VideoGame/XenobladeChronicles2'', the kingdom of Uraya is located within a gigantic whale-like Titan. The majority of the region just looks like a gigantic and beautiful cave complex, illuminated by light shining through the titan's translucent back as well as glowing plant-life and being dotted by ponds and lakes of various sizes. However, the tiny region known as the Dragon's Stomach serves as a reminder that you're still inside of a living creature, with its environs being fleshy and host to a horde of unpleasant parasitic lifeforms.
* The original ''X-Men'' game for the NES has a couple of levels inexplicably inside a giant space whale. In the comics these were used as starships by the alien Brood.
* Most ''RPG Maker'' versions have tilesets designed for these.
* ''VideoGame/{{Fallout|1}}'' has one of these as the Master's lair, kind of. It's not so much as going ''into'' something's body but it's more [[spoiler:the Master has grown like MeatMoss across the innards of the Mariposa base and combined with some of the tech]].
* ''VideoGame/{{GrimDawn}}'' features a particularly gruesome, "living" pulsating dungeon in the Ashes of Malmouth expansion. One portion of this dungeon [[spoiler:literally contains a womb.]]

[[folder:Rhythm Games]]
* DESCENT, the second level in ''VideoGame/BitTrip BEAT'', may look like tunnels filled with lava flows, but it turns out to be one of these because Commander Video's circulatory system is developing. The tunnels are blood vessels, and that means that the lava is blood. To top it all off, the boss chamber represents the heart. Also, the bassline is very likely to represent heartbeats.
* ''VideoGame/EliteBeatAgents'' had a stage where the agents had to cheerlead the white blood cells in an athlete's body into fighting off a fever. Specifically, white blood cells [[AnthropomorphicPersonification personified]] as [[HelloNurse sexy nurses]] wielding [[ImprobableWeaponUser giant syringes]], with the sickness being represented by blue-skinned men in devil costumes with giant forks.

[[folder:Shoot Em Up]]
* In ''VideoGame/{{Abadox}}: The Deadly Inner War'', the hero journeys inside a PlanetEater to rescue a princess (or lover in the Japanese version).
* Amiga game ''Anatomic Man'' takes place in a human digestive system, where you need to shoot bacteria.
* ''Andro Dunos'' goes here in Stage 3, whose background is made of pulsating alien viscera.
* ''VideoGame/{{Apidya}}'' has two of these, both bonus levels. One takes place inside a giant pike after he eats you, the other is when you fly into the guts of the dead rat that you just blasted open.
* The final level in the NES game ''Attack of the Killer Tomatoes'' took place inside a giant monster tomato.
* ''VideoGame/TheBindingOfIsaac'', makes a [[PlayedStraight self-conscious play]] at this level: Stage 4 is literally Isaac's Mom's womb. The final boss of this stage is Isaac's mom's heart, which is for some reason located in her womb. And if you kill the Heart enough times, it will be replaced by [[spoiler:Isaac himself, in fetus form]].
* A very old arcade game called ''Bio-Attack'' is comprised of this where you have to cure the patient from health problems and escape through the eye. Interestingly enough, it was apparently meant to be a licensed game based from Film/FantasticVoyage according to the Fox trademark.
* ''VideoGame/BioHazardBattle'' is a fairly standard {{Shmup}} except for the playable ships and all the enemies being organic, and the levels get more like this the further you go along.
* ''VideoGame/BlazingLazers'' has Area 4, which is inexplicably full of MookMaker brains.
* ''VideoGame/BlazingStar'' ends the game with a semi-cybernetic version, complete with Cyborged GiantSpaceFetus.
* The second level of the Amiga shoot-em-up ''Disposable Hero'', which, in addition to the requisite teeth and blood vessels, features a fire-breathing wasp made of meat which [[{{Squick}} squelches eggs out of its abdomen at you]] as its first sub-boss, followed by a skeleton that [[RuleOfCool spurts blood when you decapitate it]], and culminates in a boss fight against a tusked skull -- which you have to kill by [[YourHeadASplode shooting off the top of its head, and then popping its inflating brain sac]].
* There's usually at least one in each ''VideoGame/{{Gradius}}'' game as well; ''Gradius V'' has three, though two are of the "bio-goo takes over a capital ship" variety. The other is full of pulsating meat and ends with a fight against the heart.
** While Gradius was the staple for womb stages, it was the sister series, Salamander, that pushed the envelope for extremely graphic representation.
*** Both of the series' organic stages tend to have regenerating walls, which after being destroyed, can regenerate on top of your ship and kill you if you're not careful. ''Gradius [=ReBirth=]'' has a rather dickish variety that ''grows even larger'' whenever it regenerates.
** ''[[VideoGame/{{Gradius}} Life Force]]'' is the ur-example, which takes place inside the PlanetEater Zelos in the American version [[AllThereinTheManual according to the manual]].
*** In the original Arcade version, ''Salamander'', only the first level was a womb level. However in the Japanese Arcade version of Life Force; which was a tweaked remake of Salamander, almost all of the levels and enemies had pallet and sprite swaps to look organic. The game also included an announcer which, when you reached a new level, told you what organ of the monster you were entering and the hazards you encouter.
* ''VideoGame/TheGuardianLegend'' has a flesh zone.
* ''[[http://www.newgrounds.com/portal/view/493910 In Utero]]'', which features a sperm. The game was designed to celebrate the new baby boy of Tom Fulp, who runs Newgrounds.
* ''VideoGame/LegendaryWings'' had mid-level punishment segments in which you would be sucked into a giant's mouth if you failed to dodge his whirlwinds. These levels were ''really creepy''.
* Naizoh Habitat in ''VideoGame/{{Nanostray}} 2''. "Naizoh" even means "guts".
* The last boss of the forgotten shmup ''Philosoma'' has you whittling away at a giant ''ovum'', all the while your AIIsACrapshoot onboard computer kept saying "Fertilization" over and over at differing tones. Granted, you needed to free your wingmate from inside the ovum. Also, the ending, while the two of you escape, the computer proclaims "Fertilization succesful" and as you flee from the planet, [[spoiler: the planet turns into a...''planet-sized fetus''. It could only be explained that the planet is a gigantic egg.]]
* ''VideoGame/RType'' likes it too; ''R-Type III'' is particularly JustForFun/{{egregious}}.
** The FinalBoss of many of the games is the Bydo Womb.
** ''X-Multiply'', by the same creators is composed ''entirely'' of Womb Levels because it takes place [[FantasticVoyagePlot inside a woman]] who is infected by a microscopic alien queen that previously killed off the others it infected. What's interesting is that unlike other examples, the zones you travel in are completely twisted and alien-ish; there's rarely any sense you're flying through arteries, intestines or other organs (though one area briefly showed what appears to be villi).
** There's, of course, the boss that looks like a literal womb at the end of the original's second stage, which also reappears in later games.
* The eponymous Lost Planet of ''VideoGame/{{Silpheed}}: The Lost Planet'' is largely turned into one of these, but the organic nature of those stages is downplayed.
* In ''VideoGame/SuperAleste'', the twelfth and final area.
* 8th area in ''VideoGame/{{Zanac}}'' takes place in such location.

[[folder:Stealth Based Game]]
* Played straight in ''VideoGame/MetalGearSolid2'', as checking your map during the final act of the game gives you the pleasure of area names like 'stomach', 'rectum', and 'duodenum'. While this seemed to be just a naming quirk at the time, either in-universe or on the part of Kojima, the creepily organic properties of the Gekko units in ''VideoGame/MetalGearSolid4'' provide the delicious possibility that it may have been very literal.

[[folder:Survival Horror]]
* ''VideoGame/CliveBarkersJericho'' features this in its final Sumeria time slice, replete with dangling organ sacks.
* ''VideoGame/DeadSpace'' doesn't have an outright womb level, but several areas of the ship, as well as the structures on the colony below, have areas where every surface is covered in alien flesh, sometimes with monsters embedded in the walls.
* In ''VideoGame/DeadSpace3'', Issac and John get eaten by a Necromorph called "The Nexus". Rather than this being a death scene, they fight its organs to escape. And that's after Isaac and John voluntarily entered the same Necromorph to conduct a science experiment.
* Angela's room in ''VideoGame/SilentHill2'', which is all red and pulsating. [[spoiler:It's also where you fight the child abuse monster]]. Angela's room also has [[DoesThisRemindYouOfAnything large, fleshy pistons poking in and out of the walls]].
* Occurs very, very briefly at the end of ''VideoGame/NeverendingNightmares'' if you're on the Final Descent ending before the final cutscene.
* Done with a twist in ''VideoGame/VampireTheMasqueradeBloodlines'': Andrei's lair (an otherwise unassuming Beverly Hills mansion) is ''filled'' with furniture and decorations made entirely out of human flesh. Even the walls bleed when you cut/shoot at them. To absolutely no one's surprise, Andrei is a Tzimisce, a member of a clan notorious for being able to warp their own flesh and that of other people with their signature Vicissitude discipline.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'':
** The 92nd layer of the abyss is called Ulgurshek. and it is a "living layer" [[spoiler:Its not really a living layer, because it is not a layer at all. its a creature called a draeden, and has been around since the dawn of time, only Lolth and her most trusted servants know this though. the abyss grew around it, probably kind of like how some trees grow around part of a metal fence]]
** Ragnora, one of the {{Eldritch Abomination}}s detailed in the ''Elder Evils'' Splat book, represents corrupted life. In the suggested scenario, the [=PCs=] confront her in the Worldskin, an cave of sorts created by her corrupting effect on the planet, which resembles the interior of a living being, albeit one with foul cysts and cancers that actual provide power to her and her pseudonatural creations. During the FinalBattle (after being reduced to 200 hp or after nine rounds of combat, whichever comes first) Ragnora merges with the Worldskin and becomes far more powerful, but also [[AttackItsWeakPoint exposes a weak spot that the heroes can take advantage of.]]
** Malagarde the Hag Countess was formerly the ruler of Malbolge, the sixth Layer of Hell. Now she '''''is''''' the sixth Layer, having been turned into it when Asmodeus installed his daughter as the new ruler.
* "Nightmare Keep", a ''TabletopGame/ForgottenRealms'' module for second edition of Advanced D&D, is all about this trope.
* TabletopGame/{{Planescape}}'s ''Guide to the Ethereal Plane'' features Neth, the Plane that Lives, a demiplane that consists entirely of the innards of a very curious organism.
* The original setting for the ''TabletopGame/{{Warhammer 40000}}'' spinoff game ''Advanced Space Crusade'' (later briefly re-launched under the name Tyranid Attack) was inside Tyranid "bio-ships", sabotaging crucial "organs".
* At least one published adventure for ''TabletopGame/{{Deathwatch}}'' (one of the free ones on the game's website) has the player-characters doing the same; going into a Tyranid bio-ship in order to kill it's link with the HiveMind, also cutting off the rest of the attacking force. At least one part of the adventure had the Kill-Team moving through a hibernation chamber where various ground units (Genestealers, Warriors, hormagaunts, etc) slept while the ship was in-transit. Make too much noise and the GM better be ready for someone to start quoting [[Alien Private Hudson]] (although possibly with a nats more eloquence).

[[folder:Third Person Shooter]]
* Taken to its logical extreme in the final stage of Act 2 in ''VideoGame/GearsOfWar II''. It even ends with you [[CrowningMomentOfAwesome performing a triple chainsaw bypass.]]
** "Oh, this is just wrong...I'm coughing up blood that ain't mine!"
* Most of the Eschebone level in ''VideoGame/JetForceGemini'' takes place inside a giant creature, entering through the mouth and exiting out the... other end.
* ''VideoGame/KidIcarusUprising'' has [[spoiler:Hades' belly, which is where Pit ends up after his first battle with him ends badly. Pit also faces cellular versions of Underworld soldiers, and once he gets into the actual stomach, Hades eats random enemies to attack him.]]
* Subverted with ''[[VideoGame/LostPlanet Lost Planet 2]]'': there is no complete womb level, per se, but the boss of the first chapter has a weakspot in its body. To reach it, you have to blow off its legs, then climb into its mouth, shoot at its organs while fending off the smaller Akrid it has eating, then shoot back out it's rear end.
* The final boss battle in ''VideoGame/MDK2''. The player fights a giant froglike monster who sucks the player into his body at intervals. While the player is inside the body, [[spoiler:he defeats the boss by destroying each of the boss' organs. When all the organs are meat jelly, switch to end cutscene.]]
* Similarly, one of the tracks in the PC game ''VideoGame/{{Megarace}}'' was set up inside a Fractalian whale.
* And in the ''[[VideoGame/TransformersPreludeToEnergon Transformers Armada]]'' video game, one level takes place on a large battleship [[spoiler: who happens to be the Decepticon Tidal Wave. However, you don't find this out until he transforms at the end of the level and becomes the level boss... unless you happened to notice his head through a window while marching through a corridor- or were spoiled by either the toy or cartoon prior.]]
** A similar is shown in ''VideoGame/TransformersWarForCybertron'', where it turns out the giant {{Killsat}} that you've been flying inside throughout the second-to-last level [[spoiler:is actually Trypticon's alt mode, which you don't find out until the final minutes of the level where you have to destroy his conversion cog and fly out before he crushes you from the inside, and he becomes the level boss for the remainder of the game.]]

[[folder:Visual Novel]]
* In the ''VisualNovel/FateStayNight'' visual novel, there is one scene in Unlimited Blade Works where Shinji turns into a giant pile of what seems like the blown out insides of a strange animal multiplied in size times.
* [[spoiler:The entire Earth can become this]] in ''VisualNovel/SayaNoUta''.

[[folder:Wide Open Sandbox]]
* One of ''VideoGame/LittleBigPlanet 2's'' levels has you shrunk down and entered into a character's body in order to fight an infection inside his brain.
* During beta,''VideoGame/{{Starbound}}'' had "Tentacle" planets composed almost entirely of flesh, viscera and bodily fluids, the implication being that some kind of abomination had essentially eaten the planet and made it its body. The full release removed them but [[spoiler:made the final boss, The Ruin, this]]. Flesh biomes can still be found on some planets, both above and below ground; these places are made of quivering raw flesh in lieu of soil and stone, and home to beasts like the Hemogoblins. The large-scale mod ''VideoGame/FrackinUniverse'' returns the tentacle worlds in the form of "Atropus planets", which are if anything even worse.
* The Crimson biome from ''VideoGame/{{Terraria}}'' appears to be this; its chasms resemble giant organs, and its grass appears to be made from MeatMoss. Certain crafting stations allow you to create flesh blocks, which can be made into fleshy organ-shaped furniture. So, if you so choose, you can make a castle out of meat.

* All three tables in the pinball video game ''[[VideoGame/CrushPinball Alien Crush Returns]]''.
* The interior of [[EldritchAbomination Muud]] in ''VideoGame/{{Lusternia}}''. Intended as a hunting ground for ''very'' [[NintendoHard high-levelled]] players.
* The WebOriginal physics based side scroller ''Triachnid'' featured this as the final level. To kill the creature who took your mate and your babies, you had to do it from the inside--and don't forget to grab your babies on the way out.
* ''[[http://www.mazapan.se/news/2008/07/30/no-more-sweden/ You Have To Fertilize The Egg]]'' (from the creators of ''VideoGame/YouHaveToBurnTheRope'') is literally all about this: The player takes the role of a royal sperm (with a fancy top hat) who races against other sperm in a woman's womb in order to fertilize an egg to give birth to a princess, all the while singing a catchy song about swimming around in a vagina and creating a princess. Couldn't make this up if we tried.
** It's not just them. A prostate cancer charity made a game about getting all the sperm to the prostate so they can become semen (hot spots and cold spots kill sperm.)
* One possible area in the supreme mindfuck that is ''VideoGame/LSDDreamEmulator'' is a stretch of fleshy pink tunnels, in which your footsteps have an odd squelching sound.
* The "Cemetery" table in ''VideoGame/ThePinballOfTheDead'' appears to be made out of muscle and skin.
* One of the stages of ''VideoGame/ProjectXZone'' is located at the [[VideoGame/{{Darkstalkers}} Creator's Fetus/Fetus of God]], the same one providing the page image. Now you can experience that lovely image in 3D. Have fun!
* One of the Movie Maker segments in ''VideoGame/SonicDreamsCollection'' provides a literal example of this, inside [[spoiler: Rouge the Bat]].

!!Non-Video Game examples:

[[folder:Anime & Manga]]
* In ''{{Manga/Berserk}}'', Guts tries to kill the [[KrakenAndLeviathan Sea]] [[EvilGod God]] from the [[EatMe inside]]. In order to do that, he enters its digestive tract, cuts his way through to the heart and while fighting tons of parasites and protective symbionts as well as the Sea God's inner combat tentacles. Kentarou Miura took quite some ArtisticLicenseBiology here.
* As mentioned above, ''Anime/DragonBallZ'' had several episodes panned out where Goku and Vegeta end up inside Super Buu's body and have to avoid the hazards of his antibodies, stomach acid, imagination, steam, [[ArsonMurderAndJaywalking and worms]]. There's also the Princess Snake episode.
* ''Manga/FullmetalAlchemist'' has Ed, Ling, and Envy briefly trapped inside an endless PocketDimension in Gluttony's stomach.
* ''[[http://www.animenewsnetwork.com/encyclopedia/anime.php?id=724 RootsSearch]]'' After being presumably killed and sent to hell Moira and Buzz end up in some ... thing that looks positively alive.

[[folder: Art and Architecture]]
* The buildings of [[http://en.wikipedia.org/wiki/Antoni_Gaud%C3%AD Antoni Gaudi]], and Gaudi's style in general. Often inspired by bodily structures, they sometimes look like the inside of a LivingShip.

[[folder:Comic Strips]]
* ''ComicStrip/TheFarSide'' had explorers rowing down a river towards a gigantic bodily organ. Caption: "The heart of the jungle now well beyond them, the three intrepid explorers entered the spleen."

* ''Film/{{Innerspace}}'' features Creator/DennisQuaid being shrunk to microscopic proportions within a specialized pod and then accidentally injected into Martin Short's body. At one point in the movie he is transferred to his girlfriend by way of a kiss and literally hangs out near her womb, where he finds out she's pregnant with his child.
* ''Film/PacificRim'' has an interdimensional portal called "the Breach" through which Kaiju travel from their world to ours. Once humans manage to enter it, it resembles a series of giant blue-and-purple sphincters constantly throwing off electricity.
* The climax of ''WesternAnimation/TransformersTheMovie'' from the 1980s takes place inside of Unicron's body. As does ''Anime/TransformersArmada'', which spends at least five episodes wandering around in Unicron's innards.

* In ''[[Literature/BooksOfTheRaksura The Serpent Sea]]'', Moon and company are briefly trapped inside [[spoiler:the leviathan, after being accidentally inhaled.]] They find themselves in a series of tunnels that the giant parasites in residence chewed out.
* In the first ''{{Literature/Doom}}'' novel, Marines Flynn Taggart and Arlene Sanders are transported into a giant womb, and have to exit it via a giant pulsing vagina. Arlene quips "Hey, Fly. Do you ever feel like you're being born again?" to which Taggart politely asks her to STFU.
* In ''Literature/TheElricSaga'', the quest of Elric of Melnibone to find the sword Stormbringer leads him and Rackhir the Red Archer into the ''Pulsating Cave''. This is a cavern with a restricted-access vertical entrance scarce big enough to allow one person at a time in, and is fringed with gorse bushes on the outside. Inside the walls are of some pink flesh-like stuff which pulses as to a distant heartbeat. the walls drip with a salty viscous liquid and the cave leads to an uncomfortably hot inner chamber in which are two Black Swords, hovering in place but rendered impotent by their confinement. Elric and his bitter enemy Yyrkoon take a sword each and fight... Mournblade, the losing sword, reluctantly submits to transmuting into a scabbard for the victorious Stormbringer. Sorry, Mike, we're not quite up to speed with the realy subtle metaphors and visual puns you're using here?
* ''Literature/{{Leviathan}}'' has any scene taking place inside the eponymous airbeast. One illustration has Deryn taking Dr Barlow to the bee colonies, with the whale's ribcage forming the ceiling.
* The ''Literature/NESGodzillaCreepypasta'' has the second-to-last levels before the final boss, which are made of [[{{Squick}} disturbingly]] photorealistic gore, just like the monsters that live there. The fact that it's too detailed to be 8-bit just makes it worse.
** There's also the "Orange Tumor Cave" of Pathos.

[[folder:Live-Action TV]]
* The finale of ''Series/ChouSeiKantaiSazerX'' takes place in the body of a giant monster. Since said monster houses the spirit of the BigBad, TheHero Takuto decides teleport himself inside the monster to confront the BigBad.
* Many of the obstacles on the ''[[Series/DoubleDare1986 Double Dare]]'' [[BonusRound Obstacle Course]] qualify: "Pick-It" (a giant nose); "Down the Hatch" and later "Big Gulp" (huge mouths); "In One Ear" (a big head filled with "earwax"). "Foot Locker"/"Toe Jam", a huge foot, may also qualify somewhat.
* ''Franchise/SuperSentai'' and its adaptation ''Franchise/PowerRangers'' occasionally have fights take place inside of the body of an monster. Some notable ones from MMPR include Hatchasaurus with Jason Fighting Cardiatron, The Invenusable Flytrap fight after 4 rangers are eaten by the monster they punch there way out, and [=TurbanShell=] with the Green Ranger Tommy deliberately getting eaten so he could fire an heat ray inside the monster while the black ranger froze it's outside.
* ''Franchise/UltraSeries''
** An episode of ''Series/UltraSeven'' has the titular superhero fighting a microscopic vampiric alien parasite named Darii (or Dally, [[SpellMyNameWithAnS it depends]]). He battles it inside of a sedated girl whom Darii is possessing. This fight is also included as a stage and level in the ''Ultra Seven'' LicensedGame for the UsefulNotes/SuperFamicom.
** Two episodes of ''Series/UltramanEighty'' involved 80 shrinking himself to fight a miniscule parasite monster. The first one was Jakki, a snail-like alien pet that was accidentally swallowed by a zoo elephant, transforming the animal into the monster Zruzular, so 80 went inside the elephant to subdue Jakki. The second episode had 80 travel inside a kid-turned-monster to eliminate the source of his mutation - an alien plant called...[[ExactlyWhatItSaysOnTheTin Space Plant]]!

* Various world mythologies, Norse for instance, have the world that we see made up of the body parts (intact or dismembered) of a primordial god. Accordingly, you are in the womb level now.
* In Persian mythology, the universe is formed from the entrails of a dragon.

* It's been revealed that [[spoiler: the entire Matoran Universe is at Mata Nui's WombLevel]] in ''Toys/{{Bionicle}}''.

* ''Webcomic/LsEmpire'' has a literal case when [[spoiler: the soul of Daisy and Luigi's unborn child transports them inside Daisy with the power of the Mirror Star (Daisy is with them in there, [[MindScrew which leads to some confusion]]) complete with the 7 week old fetus in the background.]]
* The test ''Jigena's Flower'' in ''Webcomic/TowerOfGod'' is all about climbing into Jigena and finding a parasitic flower that grow jewels. Unfortunately, Jigena is a aquatic beast that sunbathes for only two hours at the surface and flips every thirty seconds in addition to being ungodly gigantic, so the test is really hard.
* An ''Webcomic/{{Oglaf}}'' strip gets very close to featuring this trope literally with "the Labi-Rinth, a labyrinth styled like a vagina". A lot of Oglaf strips are NSFW, others aren't; this one is... hard to classify. It's very ''pink'', though.

[[folder:Web Original]]
* ''[[http://www.orionsarm.com/xcms.php?r=oa-story&story=dr_yes_jolonah "Yes, Jolonah, There Is a Hell"]]'', a story in the WebOriginal/OrionsArm universe, has an unfriendly (and insane) archailect, an existence that is to us as we are to bacteria, decide that there needs to be a hell. So it creates one. Being that Hell is this archailect's body, this certainly qualifies -- as womb level, body horror, values dissonance, eldritch horror and nightmare fuel. Read it, for a view on how AI could go Really Fucking Wrong.

* The website called ''[[http://z13.invisionfree.com/The_Miasma/index.php The Miasma]]'' that promises to be "An unflinching celebration of the bizarre and extraordinary". It appears to be an entire forum made out of [[{{Squick}} living tissue]] and is run by an administrator named Neurovore.

[[folder:Western Animation]]
* ''WesternAnimation/AdventureTime'':
** In "Belly of the Beast," Finn and Jake go inside a giant rampaging monster after hearing a cry for help, only to discover a tribe of partying bears.
** In "Lady & Peebles," Princess Bubblegum and Lady Rainicorn go inside a mountain dungeon to rescue Finn and Jake from the Ice King. Said dungeon is [[EvilIsVisceral organic and ready to kill the duo]] with CombatTentacles and EyeBeams, with some metallic air ducts thrown in for good measure (in which the duo gets attacked by a giant tongue). [[spoiler:It turns out that Ricardio is behind all this.]]
* ''WesternAnimation/CaptainNTheGameMaster'' had an episode that freely dances between this and a FantasticVoyagePlot; Kevin is bitten by a video virus and the team has to go inside his body to help him fight it off.
* ''WesternAnimation/CatDog'':
** In the Grand Finale, "The Great Parent Mystery," one time the titular characters are inside the stomach of the lake monster Bessie.
** The episode "Fishing For Trouble" has Cat traveling Dog's stomach to find his fish Veronica.
** "Dog Come Home!" has Dog run away from home, but since he and Cat are attached in the middle he simply stretched the body miles and miles away from their house, where Cat stays. When Cat regrets being mean to Dog, he swallows Winslow so that he can go directly to Dog, eventually coming back out through Dog's mouth.
* ''Golemesque'' has ''House of Flesh'', a fictional ''VideoGame/{{Doom}}''-like video game based entirely on the trope being programmed by the male protagonist. The author, Edward Lee, appears to have not known how common the trope really is, referring to it as an "utterly new graphical environment". Enemy "Fungiforms" would infect areas to prevent healing, and the levels (Dermatropolis, Tumor Town, Viralville, the Labyrinth of Leprosy, etc.) sound similar to settings in Lee's earlier novels about Hell.
* ''WesternAnimation/SamuraiJack''
** In "Jack and the Farting Dragon". Jack had to cure a dragon that is suffering from an mysterious ailment. Somehow, the dragon is ''enormously'' BiggerOnTheInside and is filled with all the hazards you'd expect see in a video game level.
** In the fourth episode of the Creator/AdultSwim revival season, Jack is swallowed by a colossal worm-like beast so massive that he's about the same size as one of its cells. Of course, [[ContinuityNod he mentions that this experience is nothing new to him at this point]].
* ''WesternAnimation/SouthPark'' did it, naturally: Lemmiwinks in Mr. Slave's ass!
** And later [[spoiler: Paris Hilton]] too!
** And also when [[spoiler: Kenny (who was really a kid from Cartman's fat camp [[ItsALongStory in disguise]]) climbed inside of Ms. Crabtree's womb on a bet]].
** "The Snuke" has an unlucky bastard [[spoiler: [[ItMakesSenseInContext going inside Hilary Clinton's womb to disarm a nuke]].]]
** And there's also [[spoiler: Kyle going inside the EldritchAbomination Cartman's been transformed into after his Trapper Kepper merges with him.]]
* In the ''WesternAnimation/SpongeBobSquarePants'' episode "Sandy, [=SpongeBob=], and the Worm", Sandy thinks the Alaskan Bullworm's tongue is the worm itself, and the worm's esophagus is a cave. She soon discovers she was wrong.
* The ending of ''WesternAnimation/TheRenAndStimpyShow'' episode "Marooned" has the duo end up inside an alien. The survival guide's advice? They're doomed. This inspired the final stage in the LicensedGame mentioned above.
** In "The Boy Who Cried Rat", Stimpy tries to eat Ren (who's disguised as a mouse). Eventually, Stimpy has Ren in his mouth, but Ren goes nuts and forces Stimpy to cough him out. Just like the above example, this was also featured as a level in the SNES game.
** They've lived inside dead animals more than a few times.
