Gringill

Gringills are large eel-like enemies in Super Mario Galaxy. They have large eyes and teeth, and can be orange or lavender in color. They first appear in the Beach Bowl Galaxy, and later appear in the Drip Drop Galaxy. They can be killed, by throwing a Koopa Shell at them, while under the water. They attack simply by trying to eat Mario, similar to how Bubba from Super Mario 64 attacks.
