Stars are enemies that have appeared in Link's Awakening.
Stars are unique enemies that slowly rotate while moving around the room. They always move diagonally around the room, and bounce off of the walls and other obstacles in the area. Their pattern is easily predictable, and they only take a single slice from Link's Sword to defeat. They can be found in Angler's Tunnel, Catfish's Maw, and Face Shrine.
