Kappa

Kappa are a type of yokai, or Japanese spirit, that are often depicted as mischievous creatures who love to play pranks on humans. They are typically depicted as having green skin, webbed hands and feet, and a bowl-shaped depression on their head that is said to contain water. If a kappa is ever caught without water in its bowl, it is said to become weak and powerless. In the anime Natsume's Book of Friends, kappa are a common sight. The protagonist, Natsume, is able to see and interact with yokai, and he often encounters kappa while on his adventures. One of Natsume's friends, Madara, is a kappa who is often seen playing pranks on Natsume. However, Madara is also a loyal friend who is always willing to help Natsume when he needs it. Kappa are a fascinating and complex creatures that have been a part of Japanese folklore for centuries. They are a reminder that there is more to the world than what we can see, and that there are creatures out there that are just waiting to be discovered.
