Slime Moulds (sage study)

Slime molds is a sage study in the field of Animal Life, describing a collection of monsters and creatures that fit into three large categories: slimes & moulds, which spread outwards from a source, producing a large bulk that will 'grow' over floors, walls and ceilings, typically in subterranean locations; metamorphs, capable of some mobility, comprised of tiny creatures that will reform themselves into solid shapes or 'limbs' in order to attack and consume prey; and puddings, oozes & jellies, that do not harden their bodies (ranging from semi-liquid to gelatinous), attacking prey by producing enzymes or acids that consumes flesh and other materials, among other effects.
