->''"Just when you thought that unsightly pasta stains had no champion, and you were comfortable in a world where mayonnaise didn't fight back, comes a creature made entirely of the stuff that bursts out of mashed caterpillars. These are the rock stars of downtrodden gravy stains and greasy splotches everywhere: a large, intelligent cube of glop that can chase you down and digest you before you've accepted you're being beaten up by an overachieving dessert."''

Blob [[AliensAndMonsters monsters]]. Amorphous, often implacable due to their unique (lack of) anatomy, these creatures range from mindless eating machines to tricksy shapeshifters. Usually NighInvulnerable, and sometimes capable of VoluntaryShapeshifting. Often based on jellyfish, amoebas and similar invertebrates (or, in sillier cases, gelatinous desserts), this creature can be found throughout horror, fantasy and speculative fiction environments. Often [[HollywoodAcid acidic]], it is usually defeated by being [[KillItWithIce frozen]], or by heroes who take advantage of its chemical composition with a stream of TechnoBabble.

If it has anything resembling a mouth, {{Phlegmings}} are assured.

A recent sub-variant has become popular on the various internet art sites -- that of the SlimeGirl, aka the "Goo Girl" (Website/DeviantArt or Danbooru) or "Slime Maiden" (Website/{{Pixiv}}) -- which is effectively the Blob Monster given the CuteMonsterGirl treatment, with [[Anime/SailorMoon Jamanen]] and [[QueensBlade Melona]] being the poster girls of this variant.

In video games, these will sometimes be TheGoomba, although sometimes some [[UndergroundMonkey palette-swapped]] varieties are [[MetalSlime harder]]. They're also generally [[SuperNotDrowningSkills are resistant to drowning]], especially if it's the player-controlled character. Sometimes, they can [[AsteroidsMonster split into smaller ones when killed]].

Another feature they commonly have in video games is being highly resistant to one form of attack, yet vulnerable to another. Typically this takes the form of them being hard to hurt with conventional attacks (how do you stab something that has no heart?) but vulnerable to, say, fire or some other sort of special type of damage.

Makes a good MonsterOfTheWeek. See also MegaMicrobes. Compare MuckMonster and GreyGoo. Related to the RubberMan and TalkingPoo.



* In TheNineties, the ads for Capri Sun juice drink featured kids/teens who would move about as silvery goop sliding across the ground and reappear drinking Capri Sun.
* An Italian advertisment about some snacks involves a [[Film/TheBlob1958 Blob]] parody where a giant monster made of chocolate swallows grains of puffed rice, leaving the titular product behind.

[[folder:Anime & Manga]]
* The true forms of Pride and [[spoiler:Father]] in ''Manga/FullmetalAlchemist''; blobs of some black, shadowy substance that can manifest eyes and mouths.
* Majin Buu from ''Anime/DragonBallZ'' is a humanoid Blob who also has an absurdly powerful HealingFactor.
** Many of the Machine Mutants from Anime/DragonBallGT definately count as this. More particularly the antagonist Baby who used his liquid ability to [[BodySurf go from body to body until he found a body strong enough to have as a permanent host]]. Once he finds a host he's able to [[PowersViaPossession explore the host's full potential]].
* Tetsuo from ''Manga/{{Akira}}'' turns into a fleshy version of this when his psychic power rages out of control.
* One of these served as the very first MonsterOfTheWeek that the main character fights in ''Anime/MagicalGirlLyricalNanoha''.
* The "cells" from ''Anime/PokemonLucarioAndTheMysteryOfMew''.
* Yellow Temperance and Notorious B.I.G from ''Manga/JoJosBizarreAdventure''.
* The Slime Sisters that work under Wilhelm in ''Manga/MahouSenseiNegima'', who are extremely resilient to physical attacks, [[VoluntaryShapeshifting capable of shape-shifting]], and [[MakingASplash possess some control over water]].
* ''Anime/QueensBlade'' has the immensely popular Melona. She has all of the hallmarks and perks of an amorphous creature with every part of her body being her weapon, including and especially her breasts. Her base form being a pink gooey mass that she can mold into anybody she chooses, regardless of gender or body mass; she can even copy weapons and fighting styles, the only telltale sign between her and the real thing being the shape of her pupils. While not shown in the anime, she's very capable of absorption and can use the mass to either restore herself or make herself even stronger. Under the right circumstances, she is very much immortal.
** Despite her appearance, she's very more than capable of taking on even the strongest of the fighters and has shown to be [[ImplacableMan implacable incarnate]] and a Magnificent Bastard. Not only does she have good manipulative skills, she's not afraid to fight against anyone as she goes up against Leina several times, almost winning each time and surviving techniques and ploys that would have killed anyone else, fights the champion Aldra twice in a row and surviving both times, and holds her own against Menace, a necromancer. [[spoiler:In Rebellion, she fights under the influence of a set of armor pieces that, although it's supposed to make her stronger, also disorients her focus and form with the constant perverted vibrations, subdues most of the main cast with a simple water spell, and survives a direct hit from Claudette.]] Damn.
** Even moreso, while not seen in the anime, Melona in Rebellion is [[TookALevelInBadass turned up a few notches]] after absorbing an ancient demon, sporting a spiffy new outfit to go with it.
* ''Anime/SailorMoon''
** In the MonsterOfTheWeek category is Jamanen, known as Jellax in the DiC dub. She has quite a fanbase as it is and even makes it as a recurring enemy in one of the SNES games.
** Interestingly, slimes are a slightly recurring type of monster; the later episodes feature a bunny slime-girl named Peropero who manipulated malevolent hard candy. In one of the closing episodes, an army of female humanoid slimes are born from the many unused demon seeds.
* ''Manga/{{Naruto}}''
** Suigetsu, like the rest of the Hozuki clan, is able to switch from human form to a living mass of water, and can do this to individual parts of his body. He apparently needs to drink a lot to sustain himself, and can become a more traditional giant blob monster if he has access to a significantly large body of water.
** Konan seems to have a similar ability, only instead of turning into water she turns into [[PaperMaster paper]].
** The Three Tails filler arc features an androgynous antagonist dressed in a skin tight 'slime suit' covered with a slippery residue, although he exhibits the normal abilities associated with normal slime creatures such as puddling up and stretching.
*** He later turns into quite the BodyHorror by [[FusionDance fusing with his dead comrades]], although they [[DeathByLookingUp later get crushed by the Three Tails]].
* ''Anime/CowboyBebop'': The little black beastie [[ItCameFromTheFridge from the spare fridge]] in the back of the Bebop.
* ''Manga/FairyTail'' features Juvia Loxar as a water variant who starts out as an antagonist before joining the titular guild. Doing so protects her from most physical damage, but some magical attacks can still injure her.
* Some of the illegals from ''Anime/DennouCoil''.
* One shows up as an early MonsterOfTheWeek in ''Anime/BrigadoonMarinAndMelan''. It starts out as a puddle of pink goop, but it grows bigger and stronger by consuming zoo animals ''from the inside out''. The only way to kill it is to dehydrate it.
* The ''Anime/PrettyCure'' series features a surprising amount of these in both shapeless and shapely form, no less. Heartcatch for instance, features a large gel-like female creature made of water, although she mainly weeps. In the Fresh season, however, one of the villains creats a shadowy facsimile of Setsuna who morphs her body into tentacles as well as melts into the shadows of her opponents to ambush them.
** ''Anime/FreshPrettyCure'' features one of these as a MonsterOfTheWeek in the fourth episode, formed out of a child's ''mizuame'' (Japanese water candy). It features the ability to [[AsteroidsMonster split itself into smaller copies]] and the traditional weakness to ice and cold.
* Arguably, any [[ElementalPowers Logia user]] from ''Manga/OnePiece'' can potentially be this if it's a solid Logia. The more fitting examples include [[FillerVillain Honey Queen]] (unknown water-like liquid) from the second movie, [[GeneralRipper General Gasparde]] (candy syrup) from the fourth movie, Admiral Akainu ([[MagmaMan lava]]) and Caribou ([[DishingOutDirt mud]]).
** In the Punk Hazard arc, a gigantic creature called a "Smiley." It has a rather unique origin: it used to be a giant, lifeless mass of highly deadly liquid poison created by MadScientist Caesar Clown, but the good doctor managed to turn the toxic sludge into a living creature by somehow 'feeding' it a Devil Fruit. Said Devil Fruit allows one to turn into an axolotl hybrid, but in the toxic blob's case, it turned it into a sentient kaiju blob monster axolotl of deadly poison, who would be affectionately named 'Smiley' by Clown.
** Trebol from the Dressrosa arc possesses the Beta Beta no Mi (Stick-Stick Fruit), which gives him the ability to tap massive amounts of mucus from his body. Certain events and dialog caused a BrokenBase as to whether the fruit is Logia or Paramecia, however.
*** [[spoiler: As it turns out, it's a Paramecia: Trebol actually covers his thin body in a thick coat of mucus, thus fooling opponents into thinking he's a Logia user when they're not actually hitting his body within the goo blob in the first place.]]
* A favorite motif of Creator/HayaoMiyazaki and StudioGhibli films:
** An [[http://www.obakemono.com/obake/umibozu/ Umibozu]] appears briefly in ''PomPoko''
** The cursed gods (sort of) and [[spoiler: the decapitated Deer/Forest spirit]] in ''Anime/PrincessMononoke''
** No Face and the Stink Spirit ([[spoiler: actually a river god suffering from pollution]]) in ''Anime/SpiritedAway''
** The Witch of the Waste's familiars in ''Anime/HowlsMovingCastle''.
** A hallucination (of [[MythologyGag the Shadow]]) and [[spoiler: Lord Cob]] in ''Anime/TalesFromEarthsea''
** Fujimoto's familiars in ''Anime/PonyoOnTheCliffByTheSea''.
* Manga/GalaxyExpress999 has at least THREE instances of these; a space slime who broke away from her home planet, a trio of blob-like creatures with the pink female one showing the ability to shapeshift and a swarm that attacks the heroes in the movie.
* This also seems to be a bit of a favorite for Creator/OsamuTezuka.
** DNA Sights 999.9 features a race of black liquid female creatures as well and even helps the protagonists escape in this one.
** The main female lead in One-Million Trip: Bander Book is also this while incognito.
** An alien couple seen in the Manga/AstroBoy manga.
** The Moopi in ''Manga/{{Phoenix}}''
* Bachilus from ''Anime/BirdyTheMighty''.
* Oasis from ''Anime/KyouranKazokuNikki''.
* A few of the Nightbreed appearances in ''Anime/{{Nightwalker}}'' qualify as this.
* The ELS in ''Anime/Gundam00AwakeningOfTheTrailblazer'' are a variation. They are made of metal, and are just as tough and hard as that implies, but can shapeshift as easily as a blob monster when they wish. They can even combine together or split apart. Unlike most creatures of this type, though, they are ''not'' NighInvulnerable. If a part of an ELS dies, it generally stays dead, and they don't appear to be able to "regenerate" damage or instantly heal wounds (presumably, they'd need to gather an [[EquivalentExchange appropriate amount of raw material first]].)
* Regenerating, powering up, or changing into other forms, this is what {{Hellsing}}'s Alucard usually regresses into, though he never actually constructs any form of weaponry from it, usually resorting to bestial forms and familiars to get the job done.
* Eilis of ''Anime/{{Shinzo}}'' is a liquid metal variation of this. He specifically traps the heroes by disguising himself as an ''entire amusement park'' in the second season.
* Bubble Claw from Anime/CuteyHoney.
* [[spoiler:Oswald, Alicia's father]] in ''LightNovel/RentalMagica'', is an undead variation of this who could copy the forms of demons he's absorbed.
* Anubis from ''Anime/YuGiOhTheMoviePyramidOfLight'' first manifests as a black slime both times when he's resurrected, though the second time is into a constantly evolving beast, and liquefies when exposed to the Blue-Eyes Shining Dragon's special ability. He also summons his Sphinx monsters through this as well.
* Okaydo is fond of these as well, with slime girl Suu in ''Manga/DailyLifeWithMonsterGirl'' (a blue and green blob who can assume humanoid form, able to mimic anyone she knows, with an antenna that lets her share others' feelings), as well as slime girls in ''Manga/DeadlineSummonner'' and ''Manga/TwelveBeast''.
* Several of these appear in some of the Precure series, ranging from a generic blob-like monster to even a shadowy doppleganger of one of the Cures.
** The main villain of two of the crossover movies is literally a fusion of several monster types called Fusion, who can absorb the attacks of the Cures, changing his colors, size and abilities.

[[folder:Comic Books]]
* The ''Comicbook/{{X-Men}}'' had a villain named The Blob, who was a morbidly obese mutant who couldn't be hurt by anything (and in some continuities, could "suck up" attacks into his folds of flesh). Other, more appropriate examples include a student who was essentially a walking pile of biogenic paraffin wax with a brain, and a sentient puddle in a body suit.
* Some versions of ''Franchise/{{Batman}}'' villain Clayface portray him like this.
* Mentioned twice more on this page, ''Franchise/SpiderMan's'' villain Sandman. Another, less featured villain is Hydro-Man, who -- you guessed it -- [[ExactlyWhatItSaysOnTheTin is living water]]. Both of them can make themselves look perfectly human. On one occasion, the two accidentally combined into a mud monster, much to the later embarrassment of the former. Hydro-Man, probably due to a lack of imagination, is on the B-List ''of'' the B-List, but Sandman is still active and considered a formidable threat today.
** The ''Spider-Man'' villain Skinhead; a neo-[[ThoseWackyNazis nazi]] who can turn into a giant, flesh-eating blob (and he really does eat flesh, the first thing he does after his transformation is devour his fellow gang members). Fortunately, his skeleton remains intact and vulnerable.
** The Venom/Carnage symbiotes in their natural state...
* ''ComicBook/NewMutants''' Mercury, who is described as a "female T-1000".
* The ''ComicBook/TeenTitans'' foe Plasmus (one of the Brotherhood of Evil) is a humanoid blob of acidic protoplasm.
* ''The ComicBook/BloodSyndicate'' features Spanish superheroine Aqua-Maria, a meta human made out of living water with a bit of a language barrier to deal with.
* Comicbook/{{Empowered}}'s teammate Protean. Not a villain, but certainly a fratboyish {{Jerkass}}. [[spoiler:He owes his power to an alien sexually-transmitted disease.]]
* The Saturninans, from ''Mystery Comics'', are amoeba-like aliens and possess several useful abilities such as shape-shifting and telepathy. They fought the hero Lance Lewis.
* The Military Cook from ''ComicBook/{{Sturmtruppen}}'' ''made'' one by accident when his "mess" was struck by a lightning bolt. It devoured several soldiers before being defeated.
* The [[Comicbook/GreenLantern Sinestro Corpsman Slushh]] is a blob monster that is made up of a powerful acid contained by a transparent membrane. One of his methods of attack is to grab an enemy and pull them inside of him where they dissolve quickly. He's done this lots of times before judging by the number of bones floating about inside him.
* These showed up in ECComics' horror titles a few times. Examples include "Strictly From Hunger", where out-of-control cancer cells mutate into a ravenous blob monster, and "Ooze in the Cellar?" where the trash in a miser's cellar combines with his wife's remains, creating a living ooze that swallows everything in the house. "Terror in the Swamp" and "The Meddlers!" both have this as the result of a discarded scientific experiment in CreatingLife.
* The Chaos Devil from ''ComicBook/SonicTheHedgehogMegaManWorldsCollide'', a horror comprised of [[VideoGame/SonicAdventure Chaos]] and the [[VideoGame/MegaManClassic Yellow Devil]]. It's a very dangerous foe, nearly overpowering Bass and Metal Sonic in its debut. Even attacking its eye (Yellow Devil's weakness) had little effect against it due to the Chaos fluid, and it nearly took down Sonic and Mega Man before [[spoiler: [[BigDamnHeroes Duo stepped in]].]]
* Caitlin Fairchild of [[{{ComicBook/Gen13}} Gen13]] became this following [[spoiler: her death and rebirth]], displaying a nifty teleportation ability with it as well, though it remains to be seen whether or not she retained these powers following the DC 2011 reboot when the series was merged with DC.
** Gwendolyn at some point is transformed into the chrome variety.
* Back in its days as a MAD knock-off, {{Magazine/CRACKED}} featured The Talking Blob (CatchPhrase "So long, sucker/s) as one of its recurring characters.
* Gloo from ''ComicBook/AstroCity'' is a liquid monster who resembles a giant misshapen blob of green liquid.

[[folder:Fan Fiction]]
* A good chunk of the ''VideoGame/{{Touhou}}'' story ''FanFic/ImperfectMetamorphosis'' revolves around the local Blob Monster, also known as [[spoiler:Rin Satsuki]].
* In a BBC Sherlock fic, called [[http://sherlockbbc-fic.livejournal.com/8300.html?thread=52124268#t52124268 Aliens and Army Doctors]] Sherlock and Mycroft are members of an alien species like this. They come in peace.
* In ''Fanfic/DividedRainbow'', we have the glufferflork, a blob monster which, curiously, prefers animals such as farm livestock and woodland critters to sapient beings such as ponies and humans. It still represents a monumental threat, nearly killing Big Macintosh, tearing away at Rainbow Dash's sanity, and later threatening the whole of Ponyville.

[[folder:Films -- Animation]]
* B.O.B. from ''WesternAnimation/MonstersVsAliens'' is indestructible and [[ExtremeOmnivore can eat anything]], but is really a decent guy, if [[TheDitz not very bright]].
* In ''WesternAnimation/MonstersInc'', a monster made entirely from goo makes a cameo appearance, he is shown walking (or oozing) down the pavement but accidently slips down a rainwater gutter leaving only his eyes and mouth left.
* The Smooze from the ''WesternAnimation/MyLittlePony'' movie.
* Hexxus from ''WesternAnimation/FerngullyTheLastRainforest'' emerges from his tree prison as a tiny bit of living sludge. Absorbing the tree leveler's exhaust and engine oil lets him transform into more threatening forms.
* The original [[Film/TheBlob1958 Blob]] monster appears in ''WesternAnimation/HotelTransylvania''.
* The Greedy from ''WesternAnimation/RaggedyAnnAndAndyAMusicalAdventure'' a giant lake of liquid taffy who loves to eat sweets.
* The Lethargians from ''Literature/ThePhantomTollbooth'', little creatures made of a mucus like substance who lure victims over to them by convincing them to be lazy like them so they can eat them, after Tock saves Milo from them they form together in a lake in an attempt to drown them.
* Xibalba from ''WesternAnimation/TheBookOfLife'', is made out of slime and everything grimy.
* Morph, Silver's PirateParrot in ''Disney/TreasurePlanet'' is a pink, floating, shapeshifting, [[RidiculouslyCuteCritter ridiculously cute]] blob.

[[folder:Films -- Live-Action]]
* ''Film/TheBlob1958'', a 1950s BMovie, is the TropeMaker. As well as the BloodierAndGorier 1980s remake ''Film/TheBlob1988''.
* ''Film/TheThing1982'' is perhaps the darkest version of this. It really is an amorphous being, being simply a multi-cellular organism. Unfortunately, not only does it absorb it's prey, it is also extremely plastic, hence it can both [[ParanoiaFuel copy it's victims]] and assume grotesque, hideous and gory forms.
* The film ''Angry Red Planet'' features a blob monster with a single eye which [[SpecialEffectsFailure spins like a radar dish]] on top of its Man-of-War like body. Naturally green in color, it is electrocuted in the end. However, a small piece of it latches on to one of the astronauts and it continues to live (and try and eat the poor infectee).
* Ivan Ooze from ''Film/MightyMorphinPowerRangersTheMovie'' would sometimes transform into a sentient puddle of pink protoplasm with his face on it, and some of his warriors were created from his phlegm (they splatted really good).
* ''Franchise/{{Terminator}}'': Around 2029, Skynet invented liquid metal and started using it for the latest models. The villainous Terminators in both the second and third movies exhibit this.
** The shapeshifting liquid metal robot T-1000 in ''Film/Terminator2JudgmentDay'' could mimic everything it touched, from a floor to a human being (complete with clothes), and in human shape, it was malleable enough to simply walk "through" the bars of a prison door by flowing around them. It could also utilise its abilities in interesting ways in combat, for example turning itself back to front when pinned to a wall, or melting its head around a thrown punch to grip the attacker's arm. He was defeated by John, Sarah, and T-800 by weakening him with liquid nitrogen and later throwing him into a pool of molten iron.
** The T-X from ''Film/Terminator3RiseOfTheMachines'' had a SuperTough robotic skeleton with a Blobby cover; although she couldn't [[VoluntaryShapeshifting alter her shape]] as freely as the completely liquid metal T-1000, she could also mimic any human she touched.
* In ''Film/SpiderMan3'', fleeing convict Flint Marko is transformed into living sand. He was able to [[http://www.youtube.com/watch?v=rXOa5bWFRKw pull himself together]] to become Sandman, but the process is simultaneously awesome and traumatic-looking.
* The aliens from ''Film/ItCameFromOuterSpace'' (1953) are aware they're repellent to humans in their natural state as huge, one-eyed blob creatures covered in wispy fronds, so they try to repair their spaceship covertly. Unfortunately their actions in doing so (taking hostages and [[VoluntaryShapeshifting copying their bodies]], stealing equipment) are regarded as hostile.
* The final stage of evolution, in the movie ''Film/{{Evolution}}'', was a gargantuan critter that looked a bit like a starfish, but was described by the science-geek characters as a "giant amoeba".
* The Stuff takes this form after enough of it roams free in ''Film/TheStuff''.
* ''Film/FantasticVoyage'' had antibodies and white blood cells attacking a team of miniaturized doctors (though in all fairness they were just doing their job).
* ''Caltiki: The Immortal Monster'' is such a beast -- and intensely radioactive.
* ''X: The Unknown'' is radiation-devouring, equally radioactive, living ''mud''.
* ''The Unknown Terror'' features a flesh-devouring fungus that acts like this. Why? Because it's portrayed by [[SpecialEffectsFailure SOAP SUDS]].
* ''Film/DeathBedTheBedThatEats''. The title monster is more or less this, as it consumes its victims with yellow ecotoplasm and dissolves them in stomach acid. It's a weird movie.
* The ''Film/ParasiteEve'' movie adaptation of the novel featured this in slime girl form in a particularly surreal scene of the Mitochondria Eve taking form while she danced and promptly had sex with the bystander witnessing it.
* B-movie ''Film/TheCreepingTerror'' featured a blob monster that looked ludicrously like a giant tea cozy.
* ''The Raft'' of ''{{Film/Creepshow2}}'' is about a group of college students trapped on a raft while a oil-like blob monster that can only drift on the surface of the water tries to engulf and digest them. [[spoiler:[[KillEmAll They find out far too late it can leave the water's surface just fine.]]]]

* ''Literature/CthulhuMythos''. Creator/HPLovecraft's Shoggoths, created and hypnotically controlled by AncientAstronauts who forced them to [[ShapeShifting shapeshift]] in ways that made them functionally equivalent to heavy construction machinery. No, really. This being from a Lovecraft CosmicHorrorStory, guess [[GoneHorriblyWrong what]] [[TurnedAgainstTheirMasters happened afterwards]].
** The creatures in ''He'' and ''The Unnameable'' were also described as being at least partially gelatinous.
* The ''Barbapapas'' were a family of friendly shapeshifting blobs.
** Barbapapa moved one asterisk upwards. [[http://www.goominet.com/unspeakable-vault/vault/514/ Because.]]
* The Vom in ''[[Literature/HumanxCommonwealth Bloodhype]]'' was one of these. It was defeated by letting it absorb some of the titular drug.
* The (misnamed) title monster of ''Literature/TheClone''.
* The Vermicious Knids from ''Literature/CharlieAndTheGreatGlassElevator'' by Roald Dahl.
* Several ''Literature/{{Goosebumps}}'' books featured different blobs:
** ''Monster Blood'', and its sequels.
** ''Egg Monsters from Mars''.
** ''The Blob that Ate Everyone'' (duh).
** ''The Horror of Camp Jellyjam'' (King Jellyjam).
* The slithersucker, a giant slime mold from the coffee-table-book version of ''Franchise/TheFutureIsWild'', seems like a biologically-feasible homage to these critters.
* [[ThoseWackyNazis Joseph Goebbels]] nearly gets devoured by a giant single-celled organism in the basement of a MadScientist in the AlternateHistory novel by Brad Linaweaver, ''Moon of Ice''.
* The "Skinners" in the last book of ''Literature/TheImmortals'' by TamoraPierce. Nightmarish blobby monsters made of Chaos that are [[ImmuneToBullets Immune to Arrows]], only slightly less immune to a lot of magic and suck the life out of anything they touch. The Darklings in the same book, created by Orzone to be his spies, are likewise small, shadowy blob creatures. However, they're noncombatants and [[spoiler: gain sentience and independence and do a HeelFaceTurn]].
* A 1953 issue of ''Literature/WeirdTales'' features a short story entitles "The Slime"--an ancient life form with retractable tentacles.
* In Creator/StephenKing's short story "Grey Matter" (published in the collection ''Literature/NightShift''), a man slowly changes into a Blob Monster after drinking a can of contaminated beer.
* In ''Literature/BlueMoonRising'' by Creator/SimonRGreen, a Blob Monster that also probably qualifies as an EldritchAbomination shows up and needs to be [[KillItWithFire Killed With Fire]].
* Stanley G. Weinbaum's 1935 story "Parasite Planet" has monstrous Venusian blobs called "Doughpots" that ooze through the jungles of Venus absorbing anything that gets in their way.
* Creator/IanMcDonald's short stories in the "Chaga Saga" should count. Alien (and heavily metaphorical) blobs, chagas, are absorbing Africa at 50 meters per day, and no-one really wants to deal with it.
* ''Slime'' by William Essex. The living toxic waste of the title is more of a MuckMonster than an actual blob, but it's close enough. Someone even jokingly name-drops ''The Blob'' at one point when the protagonist is trying to warn everyone.
* ''Literature/TheDresdenFiles'': One of the short stories opens with Harry having just wrapped up a case involving Slime Golems.
* The Colloids in Tim Sullivan's ''Literature/TheParasiteWar'' were Blob Monster aliens who infested and ate human bodies.
* The titular creature in Craig Shaw Gardner's ''Bride of the Slime Monster'' was later revealed to be [[spoiler:a formerly-missing chimp sidekick in a monster suit.]]
* The "Quozzel" in the ''EnchantedForestChronicles'': it's repeatedly compared to blackberry jam, can seep into stone like a sponge, and causes earthquakes. It's fairly dangerous in its cave habitat and fairly harmless outside it.
* In Creator/LarryNiven's ''Literature/KnownSpace'', life-forms from icy worlds that use Helium II biochemistry tend to evolve into these.
* ''Literature/TheLongEarth'': The Silence/[[spoiler: First Person Singular]].
* Gelatinous green creatures known only as "blobs" menace our heroes in ''Literature/GalaxyOfFear: The Planet Plague''. Their sticky ooze lets them climb walls and hang from ceilings. They were actually created by the Imperial Biological Weapons Division to spread viruses. [[spoiler: And they [[WasOnceAMan used to be people]]; not content to just carry any old virus, they carry TheVirus.]]
* In ''Literature/SsaliaAndTheDragonsOfAvienot'', some blob monsters appear as apparently carnivorous wildlife, lurking on the ground as blue puddles and attempting to engulf their prey when approached. Most violence doesn't faze them much, though [[GoForTheEye their eyes seem to be more vulnerable than the rest of their bodies]].
* The ''grethlanth'' and the ''shleath'' in Creator/JohnWCampbell's [[Literature/ThePlaneteers "The Double Minds"]]. (A ''shleath'' is like a ''grethlanth'', only fifty feet in diameter.)
* The short story "Slime" by Joseph Payne Brennan features a black mantle of amorphous ooze heaved from the bottom of the sea onto land. It lives only to eat organic matter, and the more it eats, the hungrier it gets.
* The short story "The Thing Too Hideous to Describe" by David J. Schow is told more or less from the perspective of an alien blob monster.
* Pretty much every variant has appeared in ''Literature/PerryRhodan'', up to and including at least two cases in which giant blobs were seen covering an entire ''planet''. They've even been used for comic relief -- the "Willies" (after the handle an automated translator stuck on the first-ever encountered) who mainly function as the Central Plasma's "nursemaids" are somewhat larger-than-human and highly ''emotional'' blob monsters with human-level intelligence and a tendency to panic when things go wrong around them.
* ''LightNovel/DaybreakOnHyperion'' has White Puddings. Essentially Gelatinous Cubes with the colour and texture of firm tofu.
* The Sapiens from ''Literature/DragonsLexiconTriumvirate'':
--> Liquid flesh bubbled. A horrific frothing sound filled the atmosphere. Sloshing, slushing, slashing and burbling, it gurgled about, rolling in and out of its own figure like some species of macroscopic amoeba. Contorted from shapelessness, it started to take a form, a silhouette emerging from the metal dust that enshrouded it. As the residue of the air settled, its fluid muscle was revealed, erratic in its crazed motions. It took on the general constitution of s bipedal human grotesquely disfigured with its stands of sinew twitching like violin strings that have been plucked too hard. As it moved aimlessly, it swept out fast stretches that spanned tens of meters.
* The eponymous gem in ''TheEyeOfArgon'' [[TomatoSurprise inexplicably turns into a blob monster at the end]].
* In contrast with the [[VideoGame/DigitalDevilSaga games]], Harley Q from ''Literature/QuantumDevilSagaAvatarTuner'' absorbs the black goo from all over his base and turns into a huge beast made of the stuff

[[folder:Live-Action TV]]
* ''The [[Franchise/{{Quatermass}} Quatermass Experiment]]'' featured such a monster--an alien amoeba which absorbs organic matter that comes in contact with it. What's disturbing is that it [[AndIMustScream retains their brains in full functionality after it absorbs them.]]
* Odo, of ''Series/StarTrekDeepSpaceNine'', in his natural state. And his species, the Founders, in their natural state -- when they are healthy. (His usual form resembles a Bajoran, because that is the species that found and raised him.)
** Also, a Founder can take a lot of energy -- one shot from Klingon blaster can kill a human (or Klingon) -- but hundreds of them were needed to bring down the Founder [[spoiler:impersonating General Martok.]]
** And in one episode, Odo is subject to some substance which turns him into literal Blob Monster (i.e with similar personality).
** Odo is actually not as stable with his abilities as the average Founder, or as good at shapeshifting, due to spending most of his life separate from them. He cannot hold a solid form for more than 16 hours or so, and has difficulty mimicking specific individuals.
* Rover, from ''Series/ThePrisoner''.
* ''Series/TheSecretWorldOfAlexMack'': The title character is infamous for morphing herself into a silvery goo in order to sneak around.
** Season 2 gave her the ability to absorb anyone or anything in her mass and carry it with her.
* ''Series/TerminatorTheSarahConnorChronicles''
** There's a "female T-1000" known as the T-1001 posing as Catherine Weaver, and is shown to be far more deadly than her predecessor when it comes to terminating. Became the butt of a running joke in the fandom when she first displayed her apparently more effective shapeshifting power when she morphs out of the form of a urinal and busts out a cheesy pun. [[spoiler:Unlike the original T-1000 and similar units, this particular T-1000 is assisting the heroes.]]
** The T-1001's default form is shown in a later episode taking place during the war where it is depicted as a vaguely humanoid-looking thing with no face or defining features. [[spoiler: It later turned out to be the same T-1001 impersonating Catherine.]]
* Spoofed in ''Series/MontyPythonsFlyingCircus'', whose science fiction episode had a man-eating blancmange from 2,200,000 light-years away. It plays tennis well (at least so long as its opponents are Scotsmen) but has the weakness of being edible.
* Makuin of [[ExactlyWhatItSaysOnTheTin the Blob]] from ''Series/TensouSentaiGoseiger''. Despite what the above says, he is ''not'' a MonsterOfTheWeek, but rather a full-fledged enemy commander.
* The MonsterOfTheWeek in an episode of {{Series/Eureka}}. Carter tries to kill it with a FreezeRay, cause "[[SawItInAMovieOnce it worked in]] The Blob". It doesn't work. A salt bomb, on the other hand, works perfectly.
* In an episode of ''Series/NedsDeclassifiedSchoolSurvivalGuide'', Ned's lunch (apparently some kind of tuna casserole) [[{{Squick}} crawls off his lunch tray.]]

[[folder:Newspaper Comics]]
* In one ''ComicStrip/CalvinAndHobbes'' Sunday strip, Spaceman Spiff is devoured by a hideous gelatinous mass that crawls out of a crevice on a bleak alien planet and is immune to his blaster fire. The last panel shows Calvin making horrible faces over the cafeteria's tapioca pudding.
-->'''Susie:''' If you don't like the cafeteria's tapioca, just leave it alone!

** [[http://scp-wiki.wikidot.com/scp-171 SCP-171]]
** [[http://www.scp-wiki.net/scp-597 SCP-597 "Mother to Them All"]] is described as a giant blob of flesh dotted with teats.
** [[http://www.scp-wiki.net/scp-763 SCP-763 ("Human Beowulf Cluster")]] is a mass of human tissue that spreads over about 300 square meters and weighs more than four metric tons. It is made up of muscular tissue, blood vessels, blood and multiple examples of human organs.
** [[http://www.scp-wiki.net/scp-827 SCP-827 ("The Soup")]]. What Dr. George Farrow turned himself into while trying to cure his cancer with stem cell therapy.
** [[http://scp-wiki.wikidot.com/scp-861 SCP-861 "A Fallen Angel"]]. A mass of liquid resembling water, total volume about 1,170 liters. Oh, and it can climb any surface at a speed of up to 47 km/hour. It sometimes forces itself into people's bodies through various orifices.
** The [[http://scp-wiki.wikidot.com/scp-968 SCP-968 "Tar Baby"]]. Since its lack of solid parts limits its mobility, trying to freeze it actually makes it ''more'' dangerous.
** [[http://scp-wiki.wikidot.com/scp-999 SCP-999]], the only slime-blob-endorphin monster that is considered safe and manages to make SCP-682 LAUGH by tickling him.
** [[http://www.scp-wiki.net/scp-1537 SCP-1537 ("Akul'hil")]]. SCP-1537-A, which is what people turn into two weeks after hearing a specific phrase in the SCP-1537 language Akul'hil. They are a liquid-like substance containing human tissue that is intelligent and can move around at up to 80 km/hour. They are capable of ShapeShifting, including creating appendages such as tentacles.

* The main monster in the "Mutation!" table of ''VideoGame/BallsOfSteel'' is one, complete with multiple red eyes and sharp teeth.

[[folder:Tabletop Games]]
* ''[[Tabletopgame/DungeonsAndDragons Dungeons & Dragons]]'' has a ''lot'' of these, to the point where "ooze" is a primary creature type. Black Puddings, Ochre Jellies, Green Slimes, Gray Oozes... if it can be sneezed it has a stat block and a challenge rating.
** The ever-bizarre Gelatinous Cube. Cube-shaped so it could completely fill a dungeon corridor and thus eat organic materials off the walls and ceiling (but more importantly block off a corridor), and gelatinous because it was transparent, the better to surprise adventurers with. Lore Sjoberg describes it as, "evolutionarily adapted to graph paper." Some Monster Manual descriptions of it imply that it [[AWizardDidIt must have been made by some wizard]] to clean-up messy dungeon corridors.
** One very dangerous type is the mustard jelly, named for its yellow color and odor of mustard. Unlike most oozes, it isn't mindless, having human-level intelligence. One legend says that the first of them was created when a female elf wizard tried to polymorph herself into a grey ooze, but an error in the spell turned her into the first mustard jelly.
** A slithering tracker is another intelligent ooze. A predator, it does not eat the flesh of victims, but drains the moisture from their bodies. There are some frightening legends that say these creatures were originally humans who were transformed by evil wizards, but such tales have never been proven.
** Another example is the Mimics and various other shapeshifters, whose malleability mixed with chameleon-like powers allow them to disguise themselves as many things.
** The Gibbering Mouther: a Blob that has evolved eyes and teeth. ''Lots'' of eyes and teeth. Possibly inspired by Creator/HPLovecraft's Literature/CthulhuMythos shoggoths. In the 4th Edition, it is believed to have origins in the Far Realm. In at least some editions' interpretation, it hasn't so much "evolved" them as it simply [[BodyHorror absorbs and uses those of its victims]].
** The Aoa from the third edition Fiend Folio is a variant: it resembles a large blob of mercury, but it floats around detecting and intercepting arcane magic and spellcasters to consume the magical energy for sustenance. Apparently, some spellcasters summon them as servitors and keep them sated on the residual energy of their demesnes. And more disturbingly, YOU if you take the [[ExactlyWhatItSaysOnTheTin Ooze]][[VoluntaryShapeshifting master]] PrestigeClass.
** The demon lord Juiblex the Faceless Lord, and the god Ghaunadaur, That Which Lurks. Bwimb was once the most powerful entity on the Paraelemtal Plane of Ooze, [[spoiler:but was killed in the epic module ''Dead Gods''.]]
* ''TabletopGame/StarFrontiers'' has [[http://en.wikipedia.org/wiki/Dralasite Dralasites]] available as a PlayerCharacter race.
** Which certainly inspired in turn the various "Plasmoid" species -- Blob Monsters with intelligence -- in the ''TabletopGame/{{Spelljammer}}'' setting.
* Played with one of the factions in ''TabletopGame/StarRealms'' are The Blobs, originally very hostile to humans. But their name is a nickname, a result of the first captured alien ships only having amorphous biomass as the remains of the crew.
* ''Tabletopgame/{{Warhammer 40000}}'': One of the more nightmarish examples of this trope can be found in some varieties of Chaos Spawn -- doomed by their failure to adequately serve the Chaos Gods to live a mindless existence as a blob of organic matter [[BodyHorror endlessly mutating limbs, eyes, mouths, wings, tentacles and every appendage you can imagine -- and some you can't.]]
** And another in the Beasts of Nurgle, huge slug-like abominations constantly oozing acid and filth. And because this is 40K we're talking about, they have the personality of a BigFriendlyDog, joyously bounding over to their new friends to lick them up and down and hug them. Then they're sad that [[PleaseWakeUp their friends aren't moving anymore]], but quickly perk up when they see more moving friends-to-be in the distance.
* ''TabletopGame/{{Morta|sheen}}[[http://www.bogleech.com/mortasheen.htm sheen]]'' has several, including the standard [[http://www.bogleech.com/mortasheen/plazm.htm Plazm]], the Manga/{{Akira}}-homaging [[http://www.bogleech.com/mortasheen/ectozyme.htm Ectozyme]], the [[MindScrew not even technically alive]] [[http://www.bogleech.com/mortasheen/grenzo.htm Grenzo]], the this-trope-combined-with-BigCreepyCrawlies [[http://www.bogleech.com/mortasheen/chimerisect.htm Chimerinsect]] and the [[EldritchAbomination MY BRAIN IS MADE OF FUCK]] [[http://www.bogleech.com/mortasheen/shumoth.htm Shumoth]]
** Now there are actual monsters called slimes.
* ''TabletopGame/{{Scion}}'' presents the Hekatonkheires of Greek mythology as ''huge'' (as in, aircraft carrier huge) blobs of protoplasmic muck that can change shape at will (for example, to create a hundred giant tentacles with which to crush their enemies, leading to the common legend). Since they are fluid, no physical attack can do so much as scratch them. There are three, and most of the Dodekatheon agree that if all three were to attack Olympus together, ''Olympus will fall''.
* ''TabletopGame/GammaWorld'' adventure [=GW1=] ''The Legion of Gold''. One possible encounter was with a gigantic ameoba-like creature in a lake.
* ''HeroSystem''
** ''Hero System Bestiary''. The Living Jelly was a large monster that grew even larger (up to 128 meters high) when it ate other living things. It grabbed other creatures and used acid to dissolve them and eat them. At their largest size they could move faster than a normal human being could run.
** ''Fantasy Hero Companion''. An Amorphous Horror demon is a mass of protean ooze with five pseudopods (CombatTentacles).
* The [[GeneticEngineeringIsTheNewNuke Simic Combine]] from ''TabletopGame/MagicTheGathering'' have a knack for creating ooze creatures. [[EvilutionaryBiologist Momir Vig's]] ultimate creation, Experiment Kraj, was a gargantuan ooze mutant that could leech away the abilities of other creatures. From a later set, [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=262866 Predator Ooze]] was explicitly created as an homage to ''Film/TheBlob1958''.
* ''TabletopGame/VillainsAndVigilantes'' adventure ''The Devil's Domain''. Slime demons are gigantic amoebas with the powers of Force Field and Power Blast.
* ''Cute & Fuzzy Seizure Monsters'', the {{Mons}} {{Sourcebook}} for ''TabletopGame/BigEyesSmallMouth'' includes stats for creating these as mons. One of the sample trainers has a blob monster pet that [[ItCameFromTheFridge mutated from a really old jar of mayonnaise]].
* ''TabletopGame/{{Pathfinder}}'' includes a lot of different blob monsters, many of them identical to those found in ''TabletopGame/DungeonsAndDragons'' above. One of their more unique ones is the Hungry Flesh, which from its illustration is clearly an {{expy}} of the BlobMonster from ''Film/TheBlob1988''.
* ''Arduin'' RPG, ''The Compleat Arduin Book 2: Resources'' had quite a few of these. All had a semi-liquid composition and oozed around attacking any living creatures they could find and catch.
** The Glaft is a translucent rubbery giant amoeba. If it scores a critical hit it will cover the victim's breathing orifices and suffocate them. If not, it will stick to its victim like glue and secrete digestive acid to dissolve then.
** The Rippler is an amorphous amoeba-like monster found in underground areas that clings to ceilings and drops on creatures passing below. It wraps itself around the victim, crushing and smothering it until it dies.
** Blue Gunky is a puddle of blue slime that can fire a bolt of energy at opponents. It feeds on LifeEnergy.
** Blue Ooze looks like a puddle of bluish water. It eats by enveloping and dissolving other creatures.
** Emerald Ooze looks like a huge pulsing liquid emerald. It attacks with 1-10 CombatTentacles (pseudopods) and every living it touches is turned into more Emerald Ooze.
** Black Slime is a thick puddle of black shiny tar-like slime. It dissolves the flesh of any creature it touches and hunts by detecting the magnetic field of its victims.
** Blue Slime looks like a puddle of deep blue goo. It attacks either with 1-3 10 foot long CombatTentacles or by enveloping its victim and dissolving it. It hunts by detecting the heat given off by its target.
** Chartreuse Slime is a viscous puddle of bright green quivering goo that smells of mint. It uses 1-5 CombatTentacles to grab its prey.
** Gold Slime looks like a pool of glowing molten gold. It attacks by enveloping a target or grabbing it with a palp ({{Combat Tentacle}}s).
** Orange Slime appears to be a 1 inch thick layer of bright orange slime. It can dissolve bare flesh by touch.
** Red Slime is immune to normal fire and resistant to magical fire. It can flow on ceilings to attack victims from above.
** Silver Slime looks like a pool of liquid mercury. Its touch causes massive damage to organic materials (such as living tissue) and it can enter and leave the ethereal plane at will.
** White Slime can attack either with 1-20 CombatTentacles (each 13 feet long) or by wrapping itself around its opponent and dissolving it. In either case it can paralyze a target by touch.
** The Greater Demon Shuggondra the Bloated One is a huge white mass of squirming, quivering translucent flesh with various protuberances (pods, nodules, tentacles etc.). It has no apparent eyes or mouth. It attacks by crushing and digesting opponents or shooting out a poisonous gas. [[HealingFactor Any damage it takes is healed at a rate of 8 HitPoints per melee round]].
* Chaosium's supplement ''All the Worlds' Monsters'' Volume III
** The Blink Blob is a 40-50 foot diameter bag of protoplasm that can teleport up to 30 feet in any direction at will.
** The Lightning Mound is a mound of jelly that can sense heat and will attack any moving warm object nearby. It has a [[CombatTentacles 20 foot long tentacle]] extending from its center that does massive damage and will not let go until the target is dead.
** The Surface Tension Monster is a completely transparent giant ameoba. It can also take the shape of a humanoid or a pool of water. Once it grabs a creature it will hold on and crush the victim for 1-4 HitPoints of damage per turn until either it or the victim dies.
* Midkemia Press' ''Heart of the Sunken Lands''
** There are a variety of slimes in the Sunken Lands, all amorphous blobs of living flesh that live in wet areas and can grow as large as 120 pounds. They are aggressively carnivorous, flowing along the ground and enveloping any creature slower than they are. They attack by secreting an acidic corrosive that eats away their victim's body. They reproduce by splitting off small slimes.
** The Woodsmasher appears to be giant version of the common slimes (experts think they may be slimes that continued growing instead of splitting off baby slimes). There are no more than a couple of dozen of them in the Sunken Lands. They leave a trail of devastation 10 yards wide behind them as they travel.

[[folder:Video Games]]
* There are some ''Franchise/{{Pokemon}}'' that are blob-like in shape; examples include the Grimer family and Ditto, the latter of which is famously capable of [[GRatedSex breeding]] with [[AnythingThatMoves anything]].
** ''VideoGame/PokemonXAndY'' introduces Goomy, which looks like a slimy ball but is a [[OurDragonsAreDifferent Dragon-type]]. It then evolves into the slug-like dragon Sliggoo and finally Goodra, [[ExactlyWhatItSaysOnTheTin a large dragon made of goo]]. Unlike most examples, these have excellent special defense but low physical defence (for a [[InfinityMinusOneSword pseudo-legendary]], anyway).
* ''VideoGmae/DistortedTravesty 3'' has slimes both in it's Zelda segment, and it's [[https://www.youtube.com/watch?v=gRG7OsR8iuc RPG segment.]]
* The [[VideoGame/Disgaea3AbsenceOfJustice third]] and [[VideoGame/Disgaea4APromiseUnforgotten fourth]] games of the ''Franchise/{{Disgaea}}'' series have the Slime monster species, appearing as featureless blobs wearing horned skulls. As with some of the other examples, they boast an extremely high amount of resistance to physical attacks, and also take halved damage from non-elemental attacks, but are vulnerable to magic.
* [[http://static.tvtropes.org/pmwiki/pub/images/rocket.jpg Slimes]] are an [[MascotMook iconic,]] [[TheGoomba early-game]] enemy in the ''VideoGame/DragonQuest'' series. Though there are tougher varieties, including those [[MetalSlime made of metal.]] And surprisingly, no {{Phlegmings}}.
* The recurring Flan species of monsters in ''Franchise/FinalFantasy''. Always resistant to almost any physical damage and weak to [[ElementalRockPaperScissors magic elemental damage, usually the opposite of which they tend to use.]]
* ''Franchise/TheLegendOfZelda'' has a myriad of blob enemies, including Bots, Bits, Zols, [=ChuChus=], and other similar creatures.
** The Like-Likes, man, the ''[[DemonicSpiders Like-Likes!]]''.
** Morpha in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]''.
** ''VideoGame/TheLegendOfZeldaMajorasMask'' has a blob monster (with a frog monster inside, controlling it) as a miniboss in Great Bay Temple. If the blob absorbs you, the frog pummels you inside before kicking you out. Naturally, it is defeated by shattering it with Ice Arrows.
* Toby in the old arcade game ''[[http://en.wikipedia.org/wiki/The_Glob The Glob]]''.
* Kira's blob from ''VideoGame/ArcanaHeart'' gives her the appearance of an imposing MightyGlacier. Without it, she's only a hair above three-and-a-half feet tall.
* Abyss, the FinalBoss from ''VideoGame/MarvelVsCapcom2''.
* Visceroids Up Until ''VideoGame/CommandAndConquerTiberiumWars'' Count too
* ''VideoGame/{{Wizardry}} 8'' had enemy slimes but they were pretty vulnerable to standard weapons and magic.
* The [[CyberCyclops Bio-Devils]] from ''VideoGame/MegaManClassic''. Only shots [[AimForTheEye directed at their eyes]] will do any kind of damage to them.
** They also existed in ''VideoGame/MegaManX'' (once), ''[[VideoGame/MegaManZero Zero]]'' (twice, although it's [[RecurringBoss the same enemy only rebuilt]]) and arguably ''[[VideoGame/MegaManZX ZX]]'' (in which the creature is made out of ''magma''). Maybe also ''[[VideoGame/MegaManLegends Legends]]''.
** And then ''VideoGame/MegaManBattleNetwork'' provides us with Proto/Alpha, the AIIsACrapshoot PsychoPrototype McGuffin FinalBoss of the third game.
** As well as Mercury from Mega Man V.
* In ''VideoGame/NetHack'', the various blobs, jellies, oozes, and such aren't immune to normal damage, since that would make them too difficult, but the black pudding [[AsteroidsMonster splits into two every time you hit it with a melee weapon]], just like the D&D monster of the same name.
** A well-prepared player can turn this into a near-GameBreaker. See: [[http://nethackwiki.com/wiki/Pudding_farming Pudding farming]].
* ''Franchise/{{Ultima}}'' has slimes that, while they can be attacked in the normal ways, a non-lethal attack had a chance of causing a second slime to split off.
* The eponymous protagonist of the Wii game ''VideoGame/DeBlob'', [[ExactlyWhatItSaysOnTheTin naturally]].
** He had a different, much blobbier design in the obscure PC tech demo that started the franchise.
* The "[=VasBioInvasion=]" mod for ''VideoGame/UnrealTournament2004'' has you fighting ''sentient Biorifle blobs'' who can merge with each other to become absolutely massive in size.
* Jellies in the ''Franchise/{{Lufia}}'' series are quite pitiful early on, though Green Jellies tend to be even in strength with other enemies where they're encountered. Each game past the first also includes the Master Jelly as the BonusBoss at the end of the Ancient Cave.
* The ''VideoGame/KingdomOfLoathing'' has black puddings as food. Occasionally, one will turn out to be alive.
** There's also the acid blobs in the [[VideoGame/NetHack Dungeons of Doom]], and Lumpy the Sinister Sauce-Blob, the BigBad of the Sauceror's Nemesis Quest.
** Slimes are one of the official monster classifications ("phyla"). Depending on how you count, there are at least 20 different types of them so far.
* In the ''{{Avernum}}'' series, slimes are one of the more annoying monsters a low-level party can face. Some have an acidic touch, while others split when struck.
* ''VideoGame/{{Metroid}} Fusion'' brings us the X Parasites, nasty floating amoeba-like aliens that can take the shape of any creature they've infected and killed. The Ing of ''VideoGame/MetroidPrime 2'' are similar, and blobby Phazon creatures show up in ''Prime 3'', too.
* ''{{Gish}}'' from titular game is one of the first blob-like characters to have blob-like characteristics. Unlike most other blobs featured as main characters, Gish has a different looks and attitude.
* ''{{Locoroco}}'', which came out after that, had a blob-like main character too, but compared to Gish, it had nothing much else in common.
* Jelly Blobs in ''VideoGame/ZombiesAteMyNeighbors''. [[KillItWithIce Popsicles]] kill them instantly.
* The player character in ''VideoGame/TheOoze''.
* Typing in "blob" in ''VideoGame/{{Scribblenauts}}'' will spawn a nearly invincible blob monster. The only things that can kill is fire, and the Exploding Barrel Gun.
* Early on in ''[[VideoGame/SpaceQuest Space Quest IV]]'', you encounter a green slime in a sewer. If it touches you, it will attack you and [[FamilyUnfriendlyDeath strip the flesh from your bones]].
* Slimes and oozes appear as monsters in ''VideoGame/WorldOfWarcraft''. The Temple of Ahn'Qiraq instance featured a giant ooze boss that had to be frozen with frost damage before it could be harmed.
* Slime-blobs appear as "Lemon Drops" and "Sluggies" in ''YoshisIsland''. Super powered versions of them, named Salvo the Slime for the former and Sluggy the Unshaven for the latter, appear as bosses. Salvo is defeated by throwing eggs at him which causes him to shrink and split into Lemon Drops while Sluggy the Unshaven is nigh-invincible [[spoiler:except for its heart, located at its core; you have to pelt the slime repeatedly with eggs to deform it temporarily so you can hit the heart.]]
* The irritating oozes in ''[[VideoGame/MightAndMagic Might and Magic VII]]'' were completely impervious to physical damage and varied from merely resistant to immune with Cleric spells. Even when you have the expensive, damage-rich elemental spells in your Sorcerer's arsenal, they're as hardy as ever. They alone make the plot-critical Red Dwarf Mines particularly steep for a novice party to face.
* "Blob" is the term in a Paradox Interactive game (e.g. ''VideoGame/EuropaUniversalis'') for a nation that has taken a LOT of land. Some AI nations likely to be blobs are France, Austria and Ming China.
** England/Great Britain, Portugal and Spain tend to develop blob colonies.
* Slimes are a minor recurring enemy in the ''Franchise/{{Castlevania}}'' series, first appearing as {{Chest Monster}}s in ''Vampire Killer''.
* The blob from ''VideoGame/ABoyAndHisBlob''. The blob can change shape by eating jellybeans. In the Wii version, a lot of the enemies are more or less blob-like.
* In the little-known and extremely hard to find SNES game ''Smartball'', the player character was a sentient blob. Made even more interesting since it was essentially a puzzle-platformer set in a high-fantasy world, where you'd expect to be ''fighting'' blobs, not playing one as the hero.
* The Jell in ''VideoGame/MonsterRancher'' is a vaguely humanoid blob that can morph into a variety of things ranging from a spike-covered top to a ''helicopter''. They look even more blob-like in ''Monster Rancher 3''.
* The ''Blob'' look-alikes from the first level of ''VideoGame/AlienSyndrome'' are exactly this.
* Gels in ''VideoGame/{{Fate}}'' are very wimpy monsters -- even your pet kills them easily -- although poisonous and electrified variants turn up as you go deeper into the Dungeon.
* A character named simply The Blob was playable in the 16-bit claymation fighting game ''ClayFighter''. He was an unshaped mass of clay, and his attacks mostly revolved around [[ShapeshifterWeapon changing shape]], such as transforming into a boot when the kick buttons were pressed, or turning into a buzzsaw and flying at the opponent.
* [[PlayerCharacter Player Character version]]: Arakune (of ''VideoGame/BlazBlue'') [[spoiler: WasOnceAMan]].
* ''VideoGame/MasterOfOrion'' and its sequel has a Space Amoeba as one of the random event monsters. In the latter, if you don't defeat the monster, you're treated to a {{cutscene}} of it enveloping the planet.
* A number of ''Franchise/ShinMegamiTensei'' games feature Slimes and Blobs, usually as low-level enemies. Some other demons, such as [[http://www.popanime.net/megami/wiki/index.php?title=Abaddon Abaddon]], are pretty blob-monsterish too.
** Common [[LivingShadow Shadows]] in ''VideoGame/{{Persona 3}}'' and ''VideoGame/{{Persona 4}}'' are shapeless splotches of moving darkness with eyes, which pull themselves over surfaces with huge grasping hands (in the latter game, they can also float above-ground). They only reshape themselves into predetermined forms, such as knights or minotaurs or ''tanks'', when confronted by a foe. Even then, Mayas (the lowest enemy type) never get any alternate shape.
* ''GuildWars: Eye of the North'' introduces Oozes, blobs that inhabited the underground. Some of which ''explode''. They also have a minipet version and a tonic that turns you into one temporarily.
* Mundus, FinalBoss of ''Franchise/DevilMayCry'', begins as a living statue of a god, but once you defeat his first two forms he begins to degenerate until he ends up a horrid blob. Argosax the Chaos, FinalBoss of ''Franchise/DevilMayCry 2'', appears as one before ascending into his [[BishonenLine better-looking]], [[AmbiguousGender constantly sex-changing]] OneWingedAngel, The Despair Embodied. The penultimate boss in ''3'',[[spoiler:Arkham]], turns into one after briefly assuming the guise of [[spoiler:Sparda]].
** The [[ThatOneBoss Nightmare]] boss from the original, a huge black blob with a vulnerable core.
* Ooziums from ''[[VideoGame/NintendoWars Advance Wars: Dual Strike]]'' are giant slimes. They're immune to indirect attacks, and instantly kill any unit they attack, simply by moving onto their space and absorbing. The upshot is that they can only move one space a turn, allowing you to surround and destroy them fairly easily; their special attack means they can't counterattack. If you fail to kill it, however, you're going to lose a unit.
* The title goos from ''VideoGame/WorldOfGoo'', though they don't absorb or meld together, instead linking together to form structures.
* In the UsefulNotes/AdobeFlash game ''VideoGame/{{Amorphous}}'', you fight ''absolutely nothing'' EXCEPT for these. Unfortunately, they come in many varieties -- one explodes into deadly acid [[TakingYouWithMe on death]], another tries to ''rip your heart out'', yet another [[KillItWithFire explodes into a firey explosion]] while it's counterpart [[KillItWithIce explodes in a freezing blast]], a metal version that attacks with CombatTentacles (and is [[TacticalSuicideBoss only vulnerable when doing so]]!), etc.
** Even better/worse, some species of blob can combine to become stronger blobs! The simple Green Blob, TheGoomba of the game, can meld together with 3 other Green Blobs to form the [[NamesToRunAwayFromReallyFast Void Eater]], a [[GravityMaster gravity-controlling]] BossInMookClothing.
* The Calcinites in ''VideoGame/{{X-COM}}: Terror From The Deep'' are amorphous blobs who reside inside a diving suit.
* ''VideoGame/CityOfHeroes'' has Hamidon, which is an endgame raid boss and one of the game's most powerful enemies.
* The ''DeadlyRoomsOfDeath'' series houses both massive blob monsters, and tiny ones. Named, inventively enough Tar, Mud, and Gel, with the smaller versions being Tar Babies, Mud Babies, and Gel Babies.
* The various slimes in ''VideoGame/SecretOfMana''. They can duplicate themselves and can usually inflict StandardStatusEffects based on their color, the exception being the Shapeshifter, which instead can transform into a variety of enemies nastier then it normally is if it's not dealt with quickly.
** There's also the Lime Slime and Dread Slime bosses, which decrease/increase in size as they take damage respectively.
* ''DelveDeeper'' has both slimes and slime cubes.
* In ''VideoGame/StretchPanic'', Jelly-Chan is transformed into one based on her love of sweets.
* The slimes of ''VideoGame/ShiningInTheDarkness''.
* Belch of ''VideoGame/EarthBound''. Stinky, foul, and overall disgusting he serves as the image of this page.
* ''VideoGame/DwarfFortress'' both plays this straight and subverts it: some randomly generated creatures do not have organs and thus only die via ChunkySalsaRule. However, other ones, as well as "blood men", are made of liquid but have no way to pull themselves together: on the lightest contact they just ''split apart''.
* Glurps in ''VideoGame/MarioAndLuigi''.
* ''VideoGame/{{Minecraft}}'' has slime enemies, which split into smaller ones if you hit them.
* Chaos from ''VideoGame/SonicAdventure'', although his general shape is somehow bound to the number of chaos emeralds he ingested, and his brain is always vulnerable.
* ''VideoGame/WorldHeroes'' seems to love these as every game except ''2 Jet'' featured a doppelganger a la ''Terminator 2'' in the form of Geegus and his better half, Neo Geegus and a surprise final boss that actually used its shapeshifting powers quite frequently with Dio and Neo Dio.
* ''VideoGame/ParasiteEve'''s Mitochondria Eve qualifies as this in the first game, not only with her giant slime blob, but in a particular scene of her in the sewer and infecting a wandering crocodile in the process.
** In ''VideoGame/ParasiteEve2'' there are Amoebas which are impervious to any physical attack, drain your [=MP=] then fire some energy ball at you, and put some status affect upon you. They are also DemonicSpiders as you may not even notice them until you run into them. The Amoebas are weak to all forms of Aya's Parasite Energy powers, so one cast can quickly end them.
* ''Videogame/{{Quake}}'': Spawns. They are this trope plus DemonicSpiders. Blobs of blue goo, capable of moving ridiculously fast by bouncing around, which makes them extremely dangerous if you let them charge at you. On top of that they're MadeOfExplodium, [[ActionBomb detonating with force equal to one of the player's rockets]].
* ''{{Vindictus}}'' has Blood Jellies and Ice Jellies as minor mobs. There's also a Blood Jelly MiniBoss called Greed, which depending on your play style may actually be harder than that mission's [[BossBattle actual boss]].
* ''Videogame/{{Mardek}}'' has an Ooze monster type, which includes Water Drops, Blood Clots and Lava Bubbles, among others.
* ''VideoGame/RiseOfTheRobots'' features a slime girl variant as the final boss known as The Supervisors, not unlike the T-1000 of Terminator fame.
* Franchise/{{Kirby}} would fit the trope if he didn't have arms and legs! His blobby companions, Goopy and Chuchu are more blob-like.
** ''VideoGame/Kirby64TheCrystalShards'' has Magman, a lava version of this.
* ''VideoGame/AliceMadnessReturns'' features such creatures as the primary {{mooks}} of the game.
* The variously-colored Puyos in ''Madou Monogatari'' and its MorePopularSpinoff ''VideoGame/PuyoPuyo''.
* In ''VideoGame/TheTowerOfDruaga'', the enemies include six different colored slimes.
* ''VideoGame/RuneScape'' has the [[http://runescape.wikia.com/wiki/Cave_slime cave slimes]] and [[http://runescape.wikia.com/wiki/Jelly jellies]]. The former is a poisonous blob of ooze and the latter is a cube of gelatinous material that appears to have items inside of it.
* The character of ''VideoGame/{{Skullgirls}}'', Double, a rare slime girl variant, is a mimicking [[EldritchAbomination dark blob]] disguised as a nun.
* ''Helbreath'' has smiles as one of the weakest enemies in the game.
* ''VideoGame/CallOfCthulhuDarkCornersOfTheEarth'' featured a classic Lovecraftian monster in the Shoggoth - in this guise, a huge, semi-sentient mass of acidic slime that infested the inside of a refinery. The touch of it was so painful and damaging that J Edgar Hoover had to perform a MercyKill on a hapless victim.
* The first-person RPG ''Anvil of Dawn'' features mud-like goo girls as sturdy enemies near the end of the game.
* The main character in ''VideoGame/TastyPlanet'' and its sequel is a small glob of gray goo that gets bigger when it eats stuff.
* The titular character of Metal Morph can only turn into a puddle but his ship is capable of multiple shapes with their own weapons
* The player character in the game ''Putty'' is one of these and can absorb both enemies and items by flattening into puddle form and sinking into his mass
* ''Jelly Boy'' and its [[VideoGame/{{Jelly Boy 2}} unreleased sequel]] for the SNES features a main cast of these with their own special abilities, requiring the player to switch between characters to get access to other areas.
* The Slimes found in [[DownTheDrain the Depths]] in ''VideoGame/DarkSouls''. They aren't particularly dangerous, but the first one you meet drops on your head out of nowhere, and is guaranteed to freak you out.
* ''Franchise/ResidentEvil'' has a few of these in the form of Nyx, a flesh consuming amoeba featured in Outbreak File#2 and [[spoiler:Carla/Fake Ada's OneWingedAngel form]].
** ''VideoGame/ResidentEvil2'' has William Birkin mutate into a blob monster after being defeated several times by Claire and Leon due to the G-Virus producing body mass at a rapid pace from the HealingFactor.
* ''VideoGame/TheHalloweenHack'': The Evil Ecto, which looks like a PaletteSwap of the Soul Consuming Flames. They are found in the creepy part of Twoson sewers, which means they are basically ghosts. They have a creepy scream and can MindRape Varik with Brainshock Alpha.
* Blob monsters of various sorts show up all over ''VideoGame/AlisiaDragoon''. Some of them light on fire when attacking or being attacked.
* Small slimes show up in the Forest Abkhazia area in ''VideoGame/RogueLegacy''. They split in two when you whittle their HP away, but you can only obtain gold or items from killing the smaller slimes.
** A much larger slime, Herodotus, serves as the boss of the Land of Darkness. Like its smaller descendants, it splits into two when you reduce its HP to zero, but every time you do this, a Gravisol appears along with them. It takes several of these for Herodotus to be squished, at which point the BossRoom will likely be overrun with enemies.
* [[UniqueEnemy The Goolix]] from the first ''VideoGame/{{Pikmin}}'' game, which is made out of water and instantly drowns any non-Blue Pikmin. [[StalkedByTheBell The Waterwraith]] from the second, which for some reason is invincible unless it's struck by Purple Pikmin, rendering it into an immobile and vulnerable state. And [[spoiler:[[FinalExamBoss the Plasm Wraith]]]] from the third, [[spoiler:which has the ability to turn parts of itself into crystal, water, some kind of flammable goo, or a spike that can generate electricity. It also ''floats'']]. ''Pikmin'' in general seems to have this trope as a once-per-game tradition.
* One of the playable characters in ''VideoGame/CrushCrumbleAndChomp'' is The Glob, a shapeless, gelatinous monster that absorbs obstacles and leaves a flammable slime trail in its wake. Players with the disc-based version could also build their own variants.
* ''VideoGame/LeagueOfLegends'': Zac, the Secret Weapon, is a giant blob with a human shape and when killed can split into four more traditional blob monsters that try to reunite and if succeeded, will revive him on spot. And for a monster, he's a fun, personable and boisterous guy... [[TokenGoodTeammate compared to the psychos that reside in Zaun]].
* In ''VideoGame/TheAdventuresOfLomax'', the enemies from the space world. They look like blobs of green goo when walking, but turn into a humanoid shape when attacking.
* Nuform from ''VideoGame/DoomsdayWarrior'' is a creature made of liquid metal.
* Scoop, one of the playable characters in ''VideoGame/{{Awesomenauts}}'', is a [[LargeHam hammy]] KnightInShiningArmor who happens to be a vaguely-humanoid slime monster.
* ''VideoGame/TheUltimateHauntedHouse'' has two of these. The main one is one of the monsters in the house, a purple creature with yellow eyes that curses you, and emerges from the kitchen's cooking pot. The second is a "young blob creature" resembling an amoeba, which is an item you can pick up.

[[folder:Web Animation]]
* ''WebAnimation/HomestarRunner'': One of the animals Strong Bad makes up in the WebAnimation/StrongBadEmail "[[Recap/StrongBadEmailE119Animal animal]]" is a big vomit-like blob with Strong Bad's face named [[http://www.hrwiki.org/wiki/Da_Huuuuuudge Da Huuuuuudge]]. Strong Bad then tries to make up two more animals - the Red Steckled Elburmung and El Pardack - and Strong Bad questions why his made up animals keep turning out as "nasty blob things".
-->"Please, for the love of Pete, ''DO NOT'' feed Da Huuuuuudge."

* The Amoeba from ''Webcomic/TheIncredibleAndAweInspiringSerialAdventureOfTheAmazingPlasmaMan''
* Carbosilicate amorphs of ''Webcomic/SchlockMercenary'', of which the title character Sergeant Schlock is one. The only thing more dangerous than a carbosilicate amorph is an amorph with [[EnergyWeapon plasma-cannons]] [[GunsAkimbo akimbo]]. Their biology affords them phenomenal smell, taste, and hearing, near-immunity to directed projectile weapons, ExtremeOmnivore capabilities, and a distributed brain that involves memories being stored everywhere, even allowing them to transfer memories by handing around chunks of their own goo; unfortunately, this means all damage is functionally brain damage. They do have eyes, but said eyes aren't part of native amorph biology; they grow on trees.
* The Goo, apparently a science experiment gone wrong, was the first major enemy the heroes fought in ''Webcomic/ElGoonishShive''.
** And then it came back bigger, stronger and more deadly than before as a part of the inter-dimensional EvilOverlord's plan to kill his dimensional counterparts.
* In ''Webcomic/GirlGenius'', a long-forgotten and sealed underground MadScientist's laboratory houses a number of Glowy Monsters that look like luminous globs with tentacles... who can lash out with whip-like tongues that inject people with digestive acids/enzymes which dissolve organic matter within seconds.
* Fred and Persephone of ''Webcomic/GeneralProtectionFault'' are sentient slime molds, who can apparently paralyze humans (and aliens) and manipulate them like puppets.
* The webcomic ''Webcomic/UnicornJelly'' has a world full of sentient and non-sentient liquid-crystal beings.
* ''WebComic/{{Synthea}}'' from the webcomic of the same name was put into a stasis pod, and woken up with experimental biotechnology by a good MadScientist far in the future. The result was a green jelly-like body with a confused amnesiac human mind. She can change shape at will, streching bodyparts, creating mallets, etc., although this is not perfect, as her body drips and oozes constantly -- her "at rest" state is a puddle, and she is stuck sleeping in a big barrel. She's also more or less immortal -- she has survived being cut into pieces and having an exploding weapon go off INSIDE her head with nothing more than a headache.
* Ditto for Myrrh from ''Webcomic/TheWotch'', a maid who tried to clean up a pile of magical ingredients (with a pinch of ginger) that her insane Wizard master left out. The mess fought back, and the resultant mass vaguely took on the maid's shape, memories, and personality (with a slightly better body). Originally a bit of fanart from a sub-comic [[CanonImmigrant that was made a bit character]] in the main comic, later [[spoiler: became a secondary character, a roommate for UnluckyEverydude Ming]].
* [[SpellMyNameWithAnS Slauf/Slough]] the demon from ''Webcomic/{{Building12}}''.
* ''Webcomic/AModestDestiny'' has a textbook example.
* ''Webcomic/AlienDice'' has a couple blob monsters running around, including one of Lexx's opponents.
* ''Webcomic/TalesOfGnosisCollege'' has a bonus sequence called ''Goo Girl Genesis'' which is ExactlyWhatItSaysOnTheTin. A female undergraduate is turned into one of these as a mad science experiment.
* In ''Webcomic/RustyAndCo'', Cube and the Gibbering Mouther.
* Among its ensemble cast of odd creatures, ''Webcomic/BloodyUrban'' has the gelatinous, upside-down amoeba dude, who is a coworker of Murray and Shaz, and appears prominently in [[http://bloodyurban.smackjeeves.com/comics/1479574/weird-tea/ Weird Tea]], [[http://bloodyurban.smackjeeves.com/comics/1788817/small-talk/ Small Talk]] and [[http://bloodyurban.smackjeeves.com/comics/1958697/sickie/ Sickie]].

[[folder:Web Originals]]
* More than one student at the SuperHeroSchool Whateley Academy in the ''Literature/WhateleyUniverse'' fits the model but subverts the trope. Aqueous is living water. Plasmoid can't even get out of his room by himself. Jimmy Trauger is widely regarded across the campus as cannibalistic because he defended himself against a powerful bully by becoming several hundred pounds of carnivorous protoplasm and teaching said bully a valuable lesson. But none of these kids is a villain. Or a hero. Just someone stuck with freaky powers and a freakier body.
* The [[http://everything2.com/user/Lucy-S/writeups/March+13%252C+2009 "God Slime"]] in this story over on ''{{Everything2}}'', from their March of the Monsters.
* Mortal from ''Roleplay/TheInsaneQuestOfUnfathomableRandomness'' is one of these.
* Tren Krom from ''Franchise/{{Bionicle}}'' was at least partly gelatinous. One of the most powerful beings in the story, he originally served as a temporary god of sorts, keeping the Matoran Universe functioning while it was still being built. The limit of his powers was never known, but he could generate bodyparts at will. The fact that all that was left of him were pieces of jelly after being killed serve as more evidence that he was a blob monster.

[[folder:Western Animation]]
* Both ''WesternAnimation/ThePowerpuffGirls'' and Jenny in ''WesternAnimation/MyLifeAsATeenageRobot'' had to fight giant blob creatures which were near invincible. The former got rid of him by finding the cat that he was looking for and letting him go, the latter by freezing it with chemicals and then destroying it.
** ''WesternAnimation/ThePowerpuffGirls'' also has the [[http://en.wikipedia.org/wiki/Mojo_Jojo#The_Amoeba_Boys Amoeba Boys]].
* The bacteria monsters in "The Giant Bacteria", an episode of ''WesternAnimation/SWATKats'', which divide whenever hit. They're melted by getting electrocuted.
* ''WesternAnimation/DextersLaboratory'' had the the giant unnamed pink blob with several eyes that starred in a few episodes.
* [[http://www.comicvine.com/thrakkorzog/29-49166/ Thrakkazorg]] from ''WesternAnimation/TheTick'' animated series. Who also made a [[CloningBlues clone]] of the hero who was part this.
* The "meta-microbe" mutated by the Big Bang as well as Aquamaria in ''WesternAnimation/StaticShock''.
* The Horrible Gelatinous Blob in ''WesternAnimation/{{Futurama}}'' is a recurring character, and at one point the creators admit that given the appearance of his son his first name ''really is'' "Horrible Gelatinous".
** There are also the Trisolians, who are a race of aliens with water-like bodies.
* ''TheHerculoids'' had two of them, Gloop and Gleep.
* The "Marabounta" in ''WesternAnimation/CodeLyoko'' is a {{Cyberspace}} example.
* One of the villains in the second season of ''WesternAnimation/DynomuttDogWonder'' was named The Glob.
* ''WesternAnimation/TheSpectacularSpiderMan'''s Sandman, a victim of a FreakLabAccident that turned him into living sand, after a BigNo and a little well-deserved fretting, very much ''enjoys'' the results, since Spider-Man's punches have no effect, and he's now capable of rudimentary [[VoluntaryShapeshifting shapeshifting]], [[ShapeshifterWeapon weaponry included]]. It's mentioned in a later episode that he can only eat "raw silicates", and later yet he proves able to change his size by picking up more sand.
* The ''WesternAnimation/SilverSurfer'' animated series has a two-part episode all about this, featuring amorphous aliens called 'Virals' accidentally born from an unstable cure created by the Watchers. Anyone who entered the Universal Library with selfish intentions or attempted to use the information with such an attitude would eventually mutate as well, operating as a collective with the ability to 'control their evolution'. Only the Surfer himself was immune because his powers are derived from the power cosmic of his former master [[CosmicEntity Galactus]].
* ''WesternAnimation/{{Ben 10}}'' has an alien form for the Omnitrix called Upgrade which requires Ben to turn into a blob in order to possess technology and, well, upgrade it. There's also an episode which explains a feud between the Plumbers and a muddy alien race called Sludges who can also pass themselves off as humans.
** ''[[WesternAnimation/Ben10AlienForce Alien Force]]'' plays it straight with the alien hero form, Goop.
** ''[[WesternAnimation/Ben10Omniverse Omniverse]]'' would later revisit these two alien species with a twist
*** One of the main villains from season 1, Malware, was a failed, twisted-looking Galvanic Mechamorph with yellow lights rather than the traditional green and went around absorbing things rather than improving them. After being "upgraded", he shifted to a red color and became more bestial in nature, threatening a grey goo scenario on his own home planet.
*** Lucy from season 4's wedding episode returned as a Plumber, the first ever Sludgepuppy to become one. She made great use of her flexible shapeshifting abilities to crack down on the theft of the Plumbers' tech while at the same time annoying Gwen with her disguises.
* ''WesternAnimation/BatmanBeyond'' has the memorable FemmeFatale, Inque, a metahuman that exists as an amorphous shapeshifting black blob.
* ''WesternAnimation/TotallySpies!'' has an interesting spoof of the T-1000 which includes a liquid metal machine that can change into anything it touches, even as the smallest of drips, it can instantly duplicate one's appearance and size.
* Two of them appear in ''WesternAnimation/MartinMystery''.
* Interesting example in ''WesternAnimation/BuzzLightyearOfStarCommand'' in which Mira's race of Tangeans were shown to have evolved from blue blobs.
* ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 TMNT: Fast Foward]]'' presented us with the sinister shadow alien, Sh'okanabo.
** Also within in the series was a superhero variant; an alternate version of Michelangelo called "Blobboid".
* One episode of ''WesternAnimation/{{MASK}}'' had the heroes facing a giant amoeba-like monster that behaved just like the blob from the 1950s movie.
* From ''WesternAnimation/{{Wakfu}}'', the Dripples ("Flaqueux" in French) in episode 5. Not so much monsters, though, than cute [[TrainingThePeacefulVillagers Peaceful Villagers]].
** There's also an authentic Blob Monster coming out of a broken potion flask in episode 7.
* The ''WesternAnimation/ExoSquad'' episodes "The Greatest Fear" and "Flesh Crawls" gives us a Neosapien transformed by [[PlayingWithSyringes Neo Mega medical experiments]] into one of these, with the added ability to [[VoluntaryShapeshifting turn into anyone]].
* ''WesternAnimation/JonnyQuestTheRealAdventures'' features a shapeshifting blob-like bio computer in the episode "DNA Doomsday" who was giving a test mission to launch a group of Nuclear Missiles, and failed to realize it was a simulation. For added creepiness, it could change parts of its body into people it had come into contact with.
* ''WesternAnimation/TeenTitans'' features two of these: Plasmus, who is just a normal guy that becomes a mindless, muck-consuming monster [[InvoluntaryShapeshifting whenever he's awake]], and the [[ImplacableMan implacable]] Madame Rouge.
* ''{{Cybersix}}'' has Terra, the MonsterOfTheWeek of Episode 3. [[spoiler:[[HeroicSacrifice Its eventual death]] was a massive TearJerker]].
* ''CasperScareSchool'': one of the students at scare school is a blob-like monster. He is a background character most of the time.
* In ''WesternAnimation/DarkwingDuck'', Gosalyn is transformed into this in "Slime Okay, You're Okay".
** If you count living water as a Blob Monster, then [[MakingASplash The Liquidator]], a recurring villain and member of the FiveBadBand, would also qualify.
* Arnim Zemo's Doughboys in ''WesternAnimation/TheAvengersEarthsMightiestHeroes''.
* ''WesternAnimation/TheSimpsons'': Homer Simpson transforms into one of these in a HalloweenEpisode, after eating some mysterious space goo.
* The classic ''ComicBook/TheIncredibleHulk'' cartoon has an experimental blob monster escape. It was indestructible and could eat anything it touched. Its one weakness? Gamma radiation.
* The ''GIJoe'' episode "The Germ" had an experimental virus come into contact with some experimental chemicals and turn into a gigantic one.
* ''GIJoeRenegades'' has the Bio-Viper, which are near-indestructible and can regenerate by consuming living matter.
* ''WesternAnimation/FamilyGuy'': Peter finds a genie and is given 3 wishes. His second is to have his own theme music, which plays constantly and can't be turned off. This leads to his being threatened with having every bone in his body broken, so Peter uses wish #3 to have no bones. He even refers to himself afterwards as an amorphous blob (comic).
* The DNA Mimic in ''WesternAnimation/GodzillaTheSeries''.
* ''Franchise/MyLittlePony'':
** ''WesternAnimation/MyLittlePonyTheMovie'': The Smooze, a ''world-devouring'' blob unleashed by three witches.
** The Smooze makes a return in season 5 of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', in the episode [[Recap/MyLittlePonyFriendshipIsMagicS5E7MakeNewFriendsButKeepDiscord "Make New Friends but Keep Discord"]] when [[MadGod Discord]] brings him along as a guest to the Grand Galloping Gala. HilarityEnsues. He's much friendlier in this incarnation, albeit prone to eating all the gems he can get his ooze on.
* Captain America is briefly seen fighting one in the first episode of ''WesternAnimation/TheSuperheroSquadShow''.
* The monster of the week for the second episode of SymBionicTitan has the gang fight against a giant goo monster that seems to be defeated at the start but a piece of it manages to spy on them and alert its still-conscious mass to invade their school, turning into red-eyed silhouettes of the heroes to combat them, the heroes themselves having to resort to their new environment to fend them off and the episode ends with it being defeated by the power of mass phone calling due to a weakness in vibrations.
* A shapeshifting blob appears in ''WesternAnimation/TomAndJerryTales'' in the episode Invasion of the Body Slammers, where it assumes the form of a deranged version of Jerry to terrorize Tom, frequently exhibiting a [[SlasherSmile very wide grin]].
* ''WesternAnimation/ArchiesWeirdMysteries'' had a giant blob monster made of [[ItMakesSenseInContext tapiocca pudding]] that begins eating everyone it catches. Although a spoof of ''Film/TheBlob1958'', it actually can't dissolve people and instead they simply end up trapped within it, complicating matters for the survivors who now have to find a non-lethal means of dispatching it.
* There was a sentient pink goo in the episode ''Simon & Marcy'' in WesternAnimation/AdventureTime. WordOfGod confirmed that one such goo in one of the video games is Princess Bubblegum's parents.
* The Sheftu from ''StargateInfinity'' are this and can shapeshift into other people or even objects by touch as well as copying their memories. The only way the gang could deal with them was with how they act.
* The unfinished ''WesternAnimation/InvaderZim'' episode "The Trial" reveals that [[LethallyStupid Zim]] once made an "Infinite Energy Absorbing Blob," which ate Tallest Miyuki, the current ruler of his species. And then her successor, Tallest Spork.
* ''WesternAnimation/CourageTheCowardlyDog'': In "Katz Kandy", SelfDemonstrating/{{Katz}} creates one of these out of jelly to capture Muriel.

[[folder:Real Life]]
* Many microorganisms, such as amoebas and slime molds, move and feed in the manner of blobs.
** So do our own white blood cells, for that matter.
*** White blood cells do not so much "feed" as "search and destroy" [[note]]they hunt down bacteria and other undesirables in your blood stream, for the uninitiated[[/note]]. Yes, ladies and gentlemen. There are armies of miniscule blob monsters in our blood stream. And they are on our side.
** Trichoplax also qualifies, although it's a rather flat example.
* Slugs and snails are rather close to being "blob monsters".
* Kefir, an unusual dairy product, is cultured from lumps of material containing dozens of species of bacteria and fungi. These lumps are so full of life that they grow constantly, and periodically divide in half, much like tiny blob-monsters.
** Although all cheeses are some combination of milk and bacteria/fungus, but only one cheese has [[http://en.wikipedia.org/wiki/Maggot_cheese maggots]].
** The moral of this trope is FOR GOODNESS SAKE, [[ItCameFromTheFridge CLEAN OUT YOUR FRIDGE!!!!!]]
* Vegamite
* There is a fish called a blobfish. It... well, [[http://i.telegraph.co.uk/multimedia/archive/01565/blobfish_1565953c.jpg see for yourself.]] It's a jelly with fins and scales -- since its low density lets it float above the seabed it barely needs any muscle.
* In water, octopi are very graceful in movement. On a boat or on land, their [[http://www.youtube.com/watch?v=jfuOn3rxdy8 movement]] is strangely blobby.
* Certain sea cucumbers can melt a'la [[Film/Terminator2JudgmentDay The T-1000]] to slip through cracks and then reform as a solid organism.
* Jellyfish are basically a floating membrane surrounding a couple of primitive organ systems and dozens of tentacles. They don't have much of a shape on land, and are only somewhat better in the water.
* Averted example: In spite of the names given to it by social media and the press, the [[https://www.youtube.com/watch?v=ELoqZiamr4E sewer blobs]] in North Carolina that caused a commotion some years ago are not single, shapeless organisms. They are in fact a colony of tubifex worms, which have a tendency to show up in sewers.
* Sea slugs usually have a definite wormlike form, but every so often something like [[http://www.aphotomarine.com/sea_slug_berthella_plumula.html the yellow plumed slug]] shows up, and part of the challenge becomes figuring out how the thing is oriented.
