Kenmun are hairy water and tree spirits from the Amami islands in southern Japan. They look like a cross between a kappa and a monkey. They also closely resemble their Okinawan cousins, kijimunā. Their bodies are covered in dark red or black hair, and they have long, thin legs and arms. They are slightly larger in size than a human child. They have pointed mouths, and on top of their heads is a saucer-like depression which holds a small amount of oil or water. Their bodies smell like yams, and their drool smells terrible.
BEHAVIOR: Kenmun make their homes in banyan trees and spend their days playing in the mountains or near the water in their family groups. They particularly enjoy sumo wrestling, at which they are very skilled. As the seasons change, they migrate back and forth from the mountains to the sea.
Kenmun have a number of strange abilities. They are able to change their shapes. They often disguise themselves as people, horses, or cows. They can change into plants and blend in with the surrounding vegetation, or even disappear entirely. Kenmun can also create light. Their drool glows eerily, as do their fingertips. They have the ability to create fire from the tips of their fingers. Sometimes they use this fire to light the oil in their head-dishes. When mysterious lights are seen in the mountains or on the shores of the Amami islands, it is called kenmun machi by locals.
Kenmun like to hunt at night, lighting up their fingertips to search for food in the dark. They primarily feed on fish and small shellfish. They also enjoy slugs and snails, pulling off the shells and rolling them up like rice balls. (It is possible to identify a banyan tree inhabited by a kenmun by the sheer amount of snail shells piled up among its roots.) They absolutely hate octopus and giant clams, and will have nothing to do with them.
