Gray Ooze

These dangerous oozes are the bane of any who travel through swamps, marshes, or damp caves. Easily masquerading as pools of clear water or patches of wet stone, gray oozes lie in wait for unwary victims to reach down for a drink or step into what appears to be a puddle, then lash out with whiplike pseudopods to ensnare and consume their hapless prey.

Sidebar - Advice and Rules Gray Ooze Adaptability

Gray oozes have shown the astounding ability to overcome environmental challenges by changing their qualities. For example, some gray oozes have adapted to fully aquatic environments, replacing their movement with a swim speed and gaining a paralytic poison similar to that of gelatinous cubes. Other gray oozes have become charged with psychic energy, gaining the ability to cause nearby creatures to become confused, fascinated, or frightened for a short time.

Slimes, molds, and other oozes can be found in dank dungeons and shadowed forests. While not necessarily evil, some grow to enormous sizes and have insatiable appetites.

Sidebar - Related Creatures Amoebas Large and Small

Giant amoebas and amoeba swarms are usually found near each other, as the two oozes are part of the same life cycle. When a giant amoeba grows large enough, it can spontaneously split apart into two separate amoeba swarms, and when an amoeba swarm feeds enough, its individual components can fuse together into a single creature.

Sidebar - Additional Lore Oozing Acid

Many oozes have acidic attacks that can quickly degrade flesh, wood, and even stronger materials. Some believe that oozes are the result of alchemical or magical experimentation run amok, while others postulate that they simply emerged from the natural processes of evolution.

Sidebar - Related Creatures Other Oozes

Many varieties of these nearly mindless predators exist in the world. Some are mere variants, with different colored puddings, jellies, and oozes with little to differentiate them from those presented here other than their habitat. Others are more specialized, or even dangerously intelligent. The shoggoth is one such example, but another variety of deadly and powerful ooze is the thankfully rare blight, a creature composed of protoplasm and eyes that curses entire regions with its presence.
