* The snake scene from "Lady Terminator". [[GettingCrapPastTheRadar Still pondering how they got away with that.]]

* Music/{{Bjork}}: During the music video of "Hidden Place" from ''Music/{{Vespertine}}''fluids flow in and out of Björk's nose, mouth and ears, but she doesn't seem to be bothered by it.

* In ''Film/{{Flubber}}'', the titular Flubber shoots into a Mook's mouth, ''wriggles around inside of him'', and then explodes out the back.

* The [[http://en.wikipedia.org/wiki/Candiru candiru]]. Unlike this fish, however, more parasites make a habit of ''leaving'' through various orifices, but they usually enter as eggs and [[BodyHorror grow inside the body]].
** Generalizations about the candiru's hunting methods rest on very little evidence, as there has been precisely one documented case of a human attack, in 1997. In particular, it is not chemically sensitive to either ammonia (excreted by fish) or urea (by humans).

* This is how the larval form of the entities in ''Manga/{{Parasyte}}'' take control of their hosts, usually entering through the ear of a sleeping person to get at the brain. When the protagonist fell asleep with headphones on, his symbiote tried getting in through one of his nostrils instead. After he woke up, it had to settle for burrowing into his arm. He tied his headphone wires tight around his arm to keep it from burrowing up to his head before it went in place, screwing up the transformation process so he and it are SharingABody instead of it taking over completely.

* In ‘‘Anime/Stitch!’’ this is how Experiment 276, AKA Remmy, invades the dreams of his host: he flies into his/her ear. The most notable example is when he does it to Yuna in the two part Episode “A Recurring Nightmare”, but he also does it to Hämsterviel and even Stitch himself.

* ''Literature/WhateleyUniverse'': For several (real world) years, there was a running gag about a NoodleIncident involving [[CuteButPsycho Generator]], which everyone referred to as... [[InvokedTrope The Noodle Incident]]. However, when they finally [[http://whateleyacademy.net/index.php/original-timeline/118-so-shalt-thou-show-me-friendship gave Lancer's full]] (and-spoilerific) SuperheroOrigin story, author Phoenix Spiritus broke with tradition by describing what actually happened. It involves Jinn demonstrating that [[spoiler: even a FlyingBrick has trouble breathing when their lungs are filled with animated spaghetti]].

** The Geonosian Brain Worms enter the victims through the nose, and take control of the body.

A variation of BodyHorror, where a creature basically forces ''all of'' itself into someone else, but through an established opening of the body (as in naturally, not a cut or piercing), even if it's not really an opening ([[Film/TheMatrix like the navel]]). It could be the mouth (do not confuse with ForceFeeding, but it can overlap with AttackTheMouth), the nostrils, the ear, or through orifices below the belt. Pores could even count.

* In ''ComicStrip/CalvinAndHobbes'', one of Calvin's [[ImagineSpot fantasy sequences]] involves a frog forcing its way into his mouth and being swallowed. Which leads to the punchline: [[spoiler:he had a frog in his throat.]]

* In [[ComicBook/MarvelZombies Marvel Zombies Return]] the Zombie heroes are transported to a parallel universe similar to theirs before the plague. While searching for a cure, Zombie!Spider-Man runs into the Sinister Six, who confuse him for their version of the hero. They are extremely and understandably shocked when Zombie!Spidey gives in to his hunger and starts killing and eating them. Since his sand-like body cannot feed him, he leaves Sandman alive, who escapes. Later, he runs into his universe's Spider-Man, who, unaware of the situation, jokes around normally. Not realizing there are two Spideys, this sends Sandman into a fit of rage, reasoning that Spider-Man clearly no longer cares and rather than be converted into food he decides to kill the hero, by forcing himself into Spidey's mouth and exploding his body from inside in a rather gruesome (if bloodless) manner.

* The biotech of the villainous Yuuzhan Vong in the ''StarWars'' ExpandedUniverse often does this. Numerous creatures fit the trope more exactly by slithering into ears or eye sockets, or down the mouth.

[[folder:Mythology]]

* ''TabletopGame/DungeonsAndDragons'' 3.5 edition sourcebook ''Lords of Madness'' introduces a new (and decidedly creepy) aberration: the Tsochari (singular Tsochar), a mass of tentacles that bores into victims and can either coerce the victim into behaving itself by causing them great pain, or, kill the victim and wear the body as a disguise.

** And to crown the collection there's the DC90 Escape Artist check from the Epic rules. Combined with Enlarge Person...
*** Combined with the Exemplar class, who can among other things do stuff like substitute a Diplomacy skill check with Escape Artist, you can even do this and impress onlookers so much they will adore and admire you.

* Samus can pull this on the final boss of ''VideoGame/MetroidIIReturnOfSamus''. If you stun it with its mouth open, you can roll down its throat and into its stomach as the morph ball. It doesn't want to spit you back out until you [[AttackItsWeakPoint drop a few bombs]] and inflict massive damage.

[[folder:Webcomics]]

* A meme that arose in the months leading up to ''Film/AvengersEndgame'' suggested that ComicBook/AntMan could defeat ComicBook/{{Thanos}} by shrinking down to insect size, crawling up Thanos's butt, and expanding to human or even giant size.

* In ''WesternAnimation/CodeLyoko'', XANA's specters generally possess people by entering through the mouth or the ears.

* In one episode of ''TheSimpsons'', Groundskeeper Willie fills the auditorium with rats in revenge for being humiliated. Bart warns Milhouse not to open his mouth; of course, Milhouse starts to say "What?", at which point half a dozen rats leap in.

* The Geonosian Brain Worms from ''WesternAnimation/StarWarsTheCloneWars'' enter the victims through the nose, and take control of the body.
** A subversion occurs in Season 4, when [[spoiler: Obi-Wan voluntarily swallows a "vocal emulator", a spider-like device that changes his voice, in order to perfect his disguise as Bounty Hunter Rako Hardeen.]]

** There are tales of this sort of torture from many different situations supposedly brutal in their methods. For instance, they say the [[UsefulNotes/DynastiesFromShangToQing Imperial Chinese]] did this from time to time, [[{{Dissimile}} except that there was only one person and the rat was in a hot cauldron strapped to the victim's ass]].

* Ants, such as army ants, will often attack a larger creature's soft spots in order to bring them down or drive them off. People being attacked by army ants can expect--in addition to painful bites and blisters--to get ants in their mouth, nose, eyes and ears. There have been a few cases where ants have killed infants and small children by [[CruelAndUnusualDeath invading their mouths and noses and more or less causing them to drown in biting, stinging ants]].

* The Franchise/DCUniverse ''ComicBook/FiftyTwo'' series answers a question no one ever asked before: can [[spoiler:OrificeInvasion of a ''robot'']] be made to look horrific? The answer? Dear Nicolas Cage, yes.

[[folder:Film]]

* It's one of the trademarks of ''Series/TheXFiles''. The Black Oil a.k.a. Black Cancer a.k.a. Purity is an alien virus that gets into your body through [[EyeScream your eyes]] and mouth and assumes complete control over it, optionally using it as a host for gestating a baby alien.

* On the short-lived TV show, Series/BrainDead, the alien insects who are taking over people's bodies get in by crawling through someone's ear while they're asleep.

* ''Series/{{Sliders}}'' had an episode where Maggie gets taken over by a parasite that got in through her mouth.

* ''Series/DoctorWho'' TV Movie: the master in the form of a slug like creature crawls into the mouth of a sleeping paramedic to take control of his body.
* An episode of ''Series/{{Lexx}}'' had space carrots that take over people's bodies by ramming themselves up their anuses.

* The creature that inhabits Helen Magnus of ''Series/{{Sanctuary}}'' has a parasite exit through her ear canal [[spoiler:after she dies]]. Based on the dialogue, it got in through her pores.
* A classic ''Series/NightGallery'' episode has a man hiring someone to do away with a rival by planting an earwig in his ear at night, where it will crawl into his head, constantly eating (see "Real Life" below) -- in a karmic slip-up he gets it planted in himself. In a million-to-one fluke, he survives weeks of agony when it crawls out his other ear. With the boldness of one who's been through Hell he owns up to his deed and claims he'd do it again...[[spoiler:then he finds out the earwig was an egg-laying female.]]

* In the ''Series/RiverMonsters'' episode "Amazon Flesheaters", Jeremy Wade interviews a man who has had an unpleasant encounter with a candiru and [[{{Squick}} shows video of the removal surgery]].
* In Series 4 Episode 4 of ''Series/{{Misfits}}'', Rudy sleeps in a slug-infested room in the community center, and one of the slugs crawls up his anus. He attempts to remove it by inserting some salt.
* In ''Series/{{Supernatural}}'', demons usually enter their meat suits' mouths as smoke.
* This is how the Nogisune tends to possess or influence people in ''Series/TeenWolf''. It tok control of its first body by entering it's mouth the form of a fly. Later, while in [[spoiler: Stiles's]] body, it released many more flies. They entered Isaac through his IV pump, Ethan through his nose, Aiden through his ear, and Derek through an open wound on his back, and acted as a HatePlague for all four of them.
%%* ''Series/StrangerThings'', Will Byers [[spoiler: gets possessed]] by the Mind Flayer when the monster shoves its smoke-like tendrils through the boy's eyes, nose, ears, and mouth.

* In the MagicalGirl CrisisCrossover ''FanFic/ShatteredSkiesTheMorningLights'', [[spoiler:[[SlimeGirl Jamanen]] from ''Franchise/SailorMoon'' appears with a vastly upgraded power set. In a ShoutOut to the infamous Inque scene from ''[[WesternAnimation/BatmanBeyond Batman Beyond]]'' below, she forces herself down [[Anime/HappinessChargePrettyCure Cure Fortune's]] throat and floods her body... [[FateWorseThanDeath but this doesn't kill her]]. [[TheAssimilator The process assimilates Fortune's body into a "drone" under Jamanen's control]], after which she forces her new servant to beat [[Anime/FutariWaPrettyCure Cure Black]] to a pulp while she's [[AndIMustScream helpless to do anything but watch]].]]

** The Centaurian Slugs in the new ''Film/StarTrek'' movie crawl down through the victim's throat. WordOfGod says they're a ShoutOut to the Ceti eels.

* In the ''Series/RiverMonsters'' episode "Amazon Flesheaters", Jeremy Wade interviews a man who has had an [[UnderStatement unpleasant encounter with a candiru]] and [[{{Squick}} shows video of the removal surgery]].
