Goo Dragon

This creature is not one being- but a large colony of sentient mold, possessing a single consciousness. If part of the animal is cut off, it will find its way back and re-join. This colony scavenges bones to use as a makeshift structure- making moving around and hunting other animals easier. The colony can change the arrangement of this skeletal structure as they see fit. The more this creature eats, the more the green slime mold will grow. When the colony becomes too large and heavy to move, they will split into two creatures
