sea squirrel
Sea squirrels are also known as Sea Squas. Sea squirrels are a very rare creature in mythological stories. According to myth, there are only 3 left in the world. One lives in Indonesia, One lives in Massachusetts, and one lives in the Mariana Trench. The one in the Mariana Trench is the only male, but he is a cannibal so no one likes him. They are normally the size of a gray squirrel but can expand when they are going to eat something big, like a boat. They look like a squirrel except they have webbed feet, fangs, and a scaly body.

"Because I'm feeding the sea squirrels, duh"
