The kappa is depicted as humanoid in form and about the size of a child. Its scaly skin ranges in color from green to yellow or blue. Kappa supposedly live in the ponds and rivers of Japan, and have webbed hands and feet. Their appearance varies from region to region, however the most consistent features are a carapace, a beak for a mouth, and a plate , a flat hairless region on the top of the head that is always wet, and is regarded as the source of the kappa’s power.
