Encyclopedia Article for kappa

in Japanese folklore, a type of vampirelike lecherous creature that is more intelligent than the devilish oni (q.v.) and less malevolent toward men. Kappa are credited with having taught the art of bonesetting to humans. They are depicted in legend and art as being the size of a 10-year-old child, yellow-green in colour, and resembling monkeys, but with fish scales or tortoise shells instead of skin. On the top of their head they have hollow indentations that are filled with water; if the water is spilled, they are said to lose their supernatural powers. Legends of encounters with kappa invariably include a reference to their capacity for keeping a promise, extracted from them after forcing their heads down or by tricking them into bowing low, thus spilling out the water. They have a taste for cucumbers, and a standard way of placating kappa is to throw a cucumber into the water where they live
