Slime

Halfling Rogue rolled a 1 to Intelligence...or should it be Wisdom? Or maybe both?

The Slime, also known as the Ooze, the Gel, the Jelly, or the Goo, is a humble form of monster that pops up in absolutely every frigging fantasy setting you can imagine, and even a few science-fiction settings. It is most famous in tabletop games for its many diffuse forms in Dungeons & Dragons and in videogames for Dragon Quest (in which it serves as the mascot and also has a fucking huge array of possible slime-forms), but, like we said, you can find a slime just about everywhere if you look.

Slimes are usually low to middle tier threat levels; they are mindless masses of animate sludge, and some higher-level variants may be made of elemental matter, such as water, "liquid ice", magma, molten steel, etc. They have no culture or higher purposes, they just ooze around eating anything organic they touch and growing bigger until they have to divide. Hardly likely to outwit most adventurers, but many games make them fairly resistant to certain kinds of attack, especially physical ones, so just assuming they're harmless is a good way to get dissolved. One prominent commenter described fighting a slime as "playing a terrifying game of 'guess the immunity'," referencing to the fact that unless you have your appropriate Monster Manuals memorised, you can rarely predict what will kill a slime variety outright. And guessing wrong can sometimes be worse than not trying, because using the wrong damage type can cause the slime in question to divide. And what they are or are not vulnerable to isn't always consistent between editions.

Types of slimes and similar monsters

Gelatinous Cube

Perhaps the most notorious slime to come out of the tabletop game field is the gelatinous cube, a D&D monstrosity that takes the form of a huge cube-shaped mass of near-translucent gray or green jelly, perfectly sized for oozing through the typical dungeon corridor as a living, insurmountable barrier. Like the Rust Monster and Owlbear, it's one of those absurdities that everyone pokes fun at, but which has too much nostalgic fondness from the fanbase for anyone to seriously consider getting rid of it. Later, fortunately, it did come with a half-assed explanation: wizards breed them as living janitorial services to clean the garbage out of the perfectly-square corridors of their evil dungeons. As it's also mostly-transparent, save for the dissolving bits of armor floating in it like fruit in a jello dessert, walking straight into it only to be engulfed is an occupational hazard for dungeon-delvers. It has a paralyzing touch. Its weaknesses vary depending on the edition.

Black Pudding / Deadly Puddings

Has nothing to do with the food called black pudding. Comes in other colors besides black, depending on what environment they are found in. All of the different colors are called Deadly Puddings. Can split if hit by weapons or lightning. Black puddings can dissolve organic material and metal. White puddings look identical to ice and snow and can instantly dissolve organic matter. Dun puddings live in deserts and can instantly dissolve leather, and can also eat metal. Brown pudding live in marshes and can instantly dissolve leather and wood.

Grey Ooze

Can rapidly corrode non magical metal similarly to a Rust Monster, but cannot dissolve stone. Is immune to cold and fire. Can camouflage itself as a puddle of water. In 5th edition they can sometimes develop psychic the ability to use psychic attacks.

Green Slime

Green slimes are mostly immobile and are more similar to plants. Their only attack that they have is dropping on people who walk under them. Anybody who touches one will turn into one if they are not cured quickly. They are vulnerable only to fire, cold, and cure disease spells. They can eat through both metal and wood.

Ochre Jelly

Similar to a black pudding but somewhat weaker. Only dissolves flesh. Can split if hit by weapons or lightning.

Crystal Ooze

Native to the caverns of the Plane of Earth, these crystalline slimes usually subsist on the minerals found in rocks with the oldest being fuck hueg. While they're content to just leech what they need from their surroundings, Crystal Oozes will attack any living creature for the minerals in them and they're no push-overs either. Their slam attacks deal piercing and slashing damage and can crit on rolls of 18-20. They also give off a Subsonic Hum that can stun an opponent while the Ooze slithers over and engulfs them at their leisure. If the victim fails their Fortitude save, they become petrified and a new Crystal Ooze pops out in 1d4 hours. They're immune to the cold and electricity and resist fire; however, their bodies can shatter and split from bludgeoning and sonic attacks.

Crystal Oozes are completely different in second edition D&D. Instead they are a variant of grey ooze that lives underwater and corrodes organic material but not metal. Weapons can only deal 1 point of damage to a crystal oozes.

Slithering Tracker

An intelligent slime that is nearly transparent. It paralyzes victims and slowly drains them of plasma.

Mustard Jelly

What happens when an idiot wizard tries to polymorph their self into an Ochre Jelly. It produces poisonous fumes that smell like mustard and slow down those who breath them in. It is intelligent and can split itself in two at will, instead of splitting when hit with weapons. It cannot climb up walls or squeeze through tight spaces like ochre jellies can. It is immune to normal weapons and takes half damage from cold, and the magic missile spell heals it, and it can eat through wood.

Olive Slime

A plant like slime similar to the green slime, but even more dangerous. Like the green slime it is immobile and attacks by dropping on people that walk under it, and it produces a venom that causes numbness so the victim may not even notice it has been attack. It possesses the victims it infects and slowly eats them from the inside out, turning them into plant like zombies that melt into Olive slime when they die, and can spread the infection. It is immune to everything except acid, fire, cold, and cure disease spells, and spells that affect plants. The zombies are the same except they are weak to magic missile instead of cure disease. If a olive slime meets a green slime then one of them will destroy the other.

Stunjelly

Similar to a gelatinous cube. It disguises itself as a stone wall, although remains semi transparent. It has most of the same weaknesses as a gelatinous cube, except that cold affects it normally.

Bloodbloater

A tiny aquatic ooze that drinks blood and attacks in swarms. Looks like an oversized cell.

Flotsam Ooze

An aquatic ooze with a very sticky body which collects debris.

Reekmurk

A huge black aquatic ooze that lives in the depths of the ocean or in underground lakes. Has a vulnerability to sunlight.

Ethereal Ooze

An incorporeal ooze from the ethereal plane.

Oblex

Has the ability to create exact copies of anyone it has eaten except for the cord of slime attaching the copies to the oblex.

Bloodrot

Not actually a true slime, but is really a form of undead made from the remains of somebody who died by being completely dissolved in acid. Infects people with a magical disease called blood fever that causes the victim to melt into a puddle when they die which the blood rot eats. They can hide inside of the bloodstream of anyone who is infected with blood fever. They can also sense the location of anybody who is infected with blood fever within several miles, so if you escape from a battle with one but are infected then more will be attracted to you. Like many true oozes, it can split apart if hit by slashing or piercing damage.

Juiblex

The demon lord of slimes and oozes.

Monstergirls

Surprisingly, slimes have long been given the monstergirls treatment; Slime Girls (also known as Goo Girls) are typically not very smart, but very affectionate and horny, and their gelatinous bodies have a lot of kinky shit they can do in the bedroom. In the more restrained versions a slime will engulf a guy while milking him dry, giving him a full body hug. This frequently results in cum floating around in the slime's body, often going towards a the slime's "heart", a core of a color that contrasts the body that is said to hold the slime's soul. It is often an erogenous zone because of course it is. In more extreme cases the slime will also penetrate the guy, engaging in stuff like sounding or fucking him in the ass while he fucks her in the, well, everywhere is a hole for a Slime. There are also a few cases where vore starts to be involved, which would be a bit more true to nature for the slimes of D&D fame.

MGE Slimes

The Slime is one of the most profuse species in the Monster Girl Encyclopedia so far, second only to the Succubus family in terms of diverse members. The slimes of the MGE were heavily influenced by the slimes of the popular fantasy gaming series "Dragon Quest", with the Slime Queen and Slime Carrier in particular being derived from members of that series' vast array of slimes.

Your standard Slime in the MGE world is a dim-witted, happy-go-lucky aimless drifter that just squiggles around looking for a guy to sex. These stand out mostly via their blue coloration.

The Red Slime, in comparison, is smarter and more aggressive.

The green Bubble Slime has a unique chemical composition that causes her to constantly secrete bubbles of noxious-smelling gas. As a side-effect, she's no longer as sticky and cohesive as other slimes, making her grapples easier to escape. However, her substance is a powerful and addictive aphrodisiac, which eventually leaves her victim dependent upon regular ingestions of her drug-like mass. She was one of the first of the grimdark mamono.

The purple Dark Slime is an extremely powerful succubus/slime hybrid native to Demon Realms. The only slime-girl in the MGE with a core (thus far), they're also smart and predatory; they have the unique ability to corrupt human women, transforming them into new Dark Slimes, via a process that basically involves enveloping the women in their body, orgasmically digesting her alive, and then reforming her as a new slime.

Slime Queens are sometimes mistaken for normal slimes due to their being the same blue color. These slimes suffer a mutation that renders them incapable of physically dividing to reproduce like a normal slime; instead, they swell to massive proportions, and can manifest multiple slimegirl "bodies" from their central mass as they see fit, all of which are, of course, extensions of the slime's singular mind. The bigger she grows, the smarter she becomes. Kenkou Cross has asserted that there are actually Slime Queen variants for all of the standard slimes.

Sea Slimes are jellyfish-girls who live in the ocean, and so lack the shapeshifting prowess of their standard cousins.

Nureonagos are a Zipangu breed of slime whose name comes from a yokai that manifested as a soaking wet girl who comes wandering around on rainy nights. The Nureonago mamono is a slime with especially advanced mimicry abilities, allowing her to take the form of a solid human girl in clothes - but she can't deny her nature, and so always looks soaking wet.

Likewise, the Shoggoth is a slime-girl maid who specializes in shapeshifting, specifically in extruding pseudopods and shaping them into tools to help her do her various chores.

The Parasite Slime is a slime that can't take on a slime-girl form of its own, instead attacking human women and raping them until their mind breaks before using them as lures to attract human men to be their partners, turning them into the mindless fuck-puppets called "Slime Carriers". This is one of the two slimes that compete for the title of "most fucked-up mamono in the MGE".

The Humpty Egg is the other slime contender. See, in the region of the MGE world known as "Wonderland", there's a super-horny, busty and fluffy harpy species caled the Jubjub Bird. These harpies lay eggs, and if a man gets too close to an unhatched egg, there is a good chance that the unborn chick inside will become aware of his spiritual energies and react by bursting out of her shell as a horny loli slime-girl made of egg-guts, essential aborting herself to have sex faster. Consisting of a loli made up of goopy, semi-solid egg-yolk and surrounded by a malleable mass of egg-white they use to form the traditional slime pseudopods. These slimes actually lay eggs when they get pregnant, which usually hatch into new Jubjubs, but are more likely than "normal" Jubjub eggs to turn into Humpty Eggs. This species was met with considerable outcry when it was released, with even many loli fans going "seriously, dude, this is going too far!"
