KAPPA

Creature living in lakes, ponds and the sea

A kappa (河童, "river-child")—also known as kawatarō (川太郎, "river-boy"), with a boss called kawatora (川虎, "river-tiger") or suiko (水虎, "water-tiger"), is a reptiloid kami with similarities to yōkai found in traditional Japanese folklore. Kappa can become harmful when they are not respected as gods. They are typically depicted as green, human-like beings with webbed hands and feet and turtle-like carapaces on their backs.
