Kappa

Kappa are a yokai spirit found in traditional Japanese mythology. Kappa are distinguished by the small pool of water on their heads, their human like-appearance, and the fish scales/turtle shell on the body. The scales colors vary between green, yellow, to blue. The stories of Kappa are used to warn children about the dangers of going to rivers and lakes alone or into deep ends, as Kappa often try to lure people into the waters and drown them. Kappas are mischievous creatures who's acts range from stealing crops, to kidnapping children. They love cucumbers though and it is believed by throwing a cucumber into the river with your name on it will have the kappas leave you alone. Kappa are believed to be very intelligent, credited with having taught the art of bone-setting to humans and are able to speak Japanese. Kappa can also be very polite and loyal, so if you can befriend one, you have an ally for life.
