Kappa

Kappa are aquatic reptilian humanoids who inhabit the rivers and streams found all over Japan.

They are proud and stubborn, but also fiercely honorable and they'll always return a bow. So if you are ever attacked by one, you can trick it into bowing so low that the water in its head will spill out, which will actually cause its death!

This is the second one of my yōkai series! (Yōkai are a class of supernatural monsters, spirits and demons in Japanese folklore)
