If misfortune befalls you and you hear a snickering laugh nearby, you've been pranked by the one and only Hyehehe. 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 also taught Hoola all there is to know about pranks!
