Kappa ( 河童, meaning "water child") are, as mentioned, a type of water spirit youkai
found in Japanese folklore. Often depicted as a turtle-shelled humanoid with a bald, depressed head ringed with hair and a waterfowl's beak, they were said to suck the blood from victims in the water through their anus, sometimes pulling their liver out in the process. However, like so many mythical beings they evolved drastically over time; they became much more moderated in depictions and actions, sometimes even going so far as to become friends with humans or at least help in some situations. It is said that whenever one should meet a kappa, if you need to escape you must bow to them; they are incredibly polite for whatever reason and will bow back. The top of their head is full of water and should they spill this water they will become weak and powerless, and thus easily escaped. They are also incredibly fond of cucumbers
and sumo wrestling.
In some regions of Japan they are said to transform with the seasons and become land-borne creatures.
