Amoeba Swarm

An amoeba swarm consists of thousands of individual single-celled organisms held together by acrid-smelling slime. As ravenous as they are mindless, amoeba swarms use no tactics.

Ooze

Source Bestiary pg. 254
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.
