Underground Serpent

(Description) Yellow eyes, seaweed over it's back, no hair nor clothes, green and blue color skin, and long ears on sides.
This is a underground serpant that lurks in the water underground waiting for it's prey to appear. It eats anything that gets close to it. (If you don't know, this is a underground serpent.) It can dig really fast and when it gets to the surface, it disguises itself as a human being and just wanders around. At one point it goes back down to the ground were it usually stays it's whole life.
