Kappa are Japanese water spirits, which take the form of a hunched over turtle man. They inhabit lakes and rivers, taunt fishermen, and sometimes abduct children, although a beneficial relationship can be established with them. Kappa are also very proud of their martial arts prowess, and possess superior strength and speed. The Kappa has one weakness: Each has a "bowl" on it's head which must remain filled with water from it's native river or stream. If one can trick the Kappa into spilling this water he will quickly dry up and become immobilized.
