Mold Thing (animal)
It is often unclear with slime beings how much of its mass must be destroyed to 'kill' it. Sometimes, the residue of a slime dries out and spends centuries in a state of quasi-hibernation and over its long slumber becomes exposed to magical energies or becomes host to a lost soul. The mold thing takes humanoid form and drags itself from the wall, searching for living creatures to envelop and feed off of before splitting off into a new mold thing as a form of reproduction.
