Kappa of Japan: Monsters of the World
The Kappa is a demon of Japanese folklore. It is said to be extremely strong, and it can pull victims into the water to eat them. It fills the top of its hollow head with water to keep its powers. Defend yourself by bowing so deeply, so that when it bows back, it spills the water from its head. Also have some cucumber handy, so if you chance upon one, you can hand it to it, and run!
