The Hyehehe is a tall, red anthropomorphic hyena monster that seems to be made of patchwork. This triple-eared trickster revels in the hot and humid weather patterns characteristic of Earth Island, and uses it as a base or operations for its scheming. The Monster adorns its motley coat with a range of foreign symbols observed from the human world, and styles itself as a kind of court jester for its own world. It can bend its body and reality to its own will, like a twisted cartoon character.
