Oysteraah

Oysteraah is a giant thorny oyster, mutated by radioactive waste dumped by the British nuclear power industry in the 1960s. The creature periodically raids coastal towns in search of food.

Slugplodicus

The Slugplodicus is a massive, mollusk-like saurian recently discovered in deep South Asian jungles. The creatures are massive, measuring up to 40 feet from toes to the tip of the eyestalk. They are generally peaceful, but will aggressively attack any threat towards their young.

Carrion Slug

Carrion Slug are among the small group of rare mollusks to inhabit Hell. As the infernal planes are nearly devoid of water, the slugs have taken to using other liquids to obtain moisture. The creatures will slowly swarm on a sleeping demon or soul and rapidly drain it of all blood, leaving a withered husk in the morning. They are generally regarded as pests and are exterminated on sight, although several demon species enjoy feasting upon them, usually raw.

Terrschnecke

Terrschneckes are a bred of large, land dwelling mollusks. Like other land mollusks (such as snails or slugs,) Terrschneckes have only one "foot," however they have evolved a number of stump-like protrusions which act as "legs," which allows the creature to obtain considerable speeds when chasing prey. Terrschneckes have no eyes, it is believed they navigate though smell and a form of echo location.

Logomachcite

Logomachcite are strange mutations which suddenly appeared in the Amazon river delta. The creature seems to have characteristics of fish, mammals, and mollusks. They are omnivores, but only seem to be opportunistic hunters, preferring to graze upon fungus and lichens. Thus far the creature has not yet been scientifically classified.

C'Thlunnagh'ah

Born in the dark spaces between the stars, the entity known as C'Thlunnagh'ah lies in wait in his Earthly prison. Older than mankind itself, he is beyond petty concepts such as good or evil. There are merely those who exist to feed his hunger. He has terrorized multiple worlds since the beginning of time, and when the stars are right he shall be reawakened. Long after mankind has gone, beasts shall walk the Earth, and C'Thlunnagh'ah will rule among them.

Rock Mollusk

Rock Mollusks are gigantic predatory land-dwelling mollusks which thrive in rocky, mountainous areas. They possess a highly efficient metabolisim, which allows them to go for large periods of time without eating. Instead of chasing prey Rock Mollusks usually wait in ambush under their rocky, camouflaged "shells."

Mongolian Death Snail

Oversized, carnivorous snails that thrive in the heat of the Mongolian deserts. Unlike every other mollusk on Earth, this particular breed of snail enjoys the dust and dry conditions. To adapt to desert life the snails turned predatory. Sharp bony teeth and powerful acids can dissolve prey in a matter of minutes. Their fierce reputation comes the suprise desert travels often find of their skeletal victims.
