The "kappa" is said to be roughly humanoid in form and about the size of a child, inhabiting the ponds and rivers of Japan. Clumsy on land, they are at home in the water, and thrive during the warm months. It is typically greenish in color (or yellow-blue), and either scaly or slimy skinned, with webbed hands and feet, and a turtle-like carapace on its back. Inhuman traits include three anuses that allow them to pass three times as much gas as humans. Kappa are generally the size and shape of a human child, yet despite their small stature they are physically stronger than a grown man.
