Orgslime

Orgslimes are small, white, glowing oozes. They have 3d8+9 hit points, and deal acid damage in 1d6+1 attacks. Their name is earned by the corrosive effect their slime has on organic matter, dealing 1d4 damage on contact. If struck by a weapon or other inorganic object, their slime will stick to it, and cause it to glow.

They can also be entirely inanimate, sticking to walls and floors where the Orgslimes have been. They still deal 1d4 acid damage on contact.

If observed very closely, one can see that they are made up of countless microorganisms, who form complex patterns.
