The Kappa is a yokai, or spirit that can be found by rivers, ponds and other bodies of water. The size of a child, kappas vary broadly in appearance, but typically have a beak, a turtle shell and a bowl -shaped indentation on the top of their heads, that contains water vital to a kappas well being. Kappas have unpredictable temperaments, while some are friendly and mischievous others are bloodthirsty maniacs with an appetite for human flesh.  Kappas are also fond of cucumbers.  In the event a kappa tries to drown, tickle or eat you, they can be warded off with an offering of cucumbers. Go ahead and try it next time you encounter a kappa. If you do not have any cucumbers, you can try tricking the kappa. A common way to trick a kappa is to bow in respect. Kappas typically feel obliged to bow in response, and when they bow, out spills the water and with it their powers. However, some modern kappas have become wise to this tactic, and will tear your head clean off your shoulders if you attempt this maneuver. The Gloam Tourism Association recommends that an explorer should always carry at least three cucumbers in their travel kit. Not only can they save your life, they are also high in fiber and vitamin K.
