In Japanese folklore there are creatures known as Kappa (河童). These aquatic creatures are often described as having a somewhat humanoid form, around the size of a child and tend to dwell within ponds or rivers. They have scaly skin which ranges in colour (greens, blues and yellows), they have webbed hands and feet, have a somewhat fishy odor, but their most notable of all their features is an indentation on the top of their head that is used to hold water; this spot is believed to be the source of their power. When a Kappa leaves the water, this indentation must be full of water, however if it were to spill out the Kappa would be unable to move.
Kappas are said to be rather mischievous and trouble making water sprites, and their pranks range from being innocent (i.e. farts or looking up a woman’s kimono) to being malevolent (i.e. luring people or animals to a water source and drowning them, kidnapping children and even raping women). However one major downfall for the Kappa is that they obsess over being polite, so if one is ever confronted by a Kappa a simple deep bow towards the creature would result in him returning the gesture. In doing so, the water which is kept in the bowl on the Kappas head would spill, leaving the Kappa unable to move until the bowl was refilled. If a human was to refill the Kappas bowl, legend tells that the Kappa would then serve them for all eternity.
You forgot to tell about how they SUCK BLOOD FROM THE ANUS OF THEIR VICTIMS! Hey guise, it’s the JAPAN we’re talking...
