The Kappa lives in the rivers and waterways of Japan. It is bigger than a turtle, but has a turtle shell, or maybe scaly skin like a fish, or sometimes fur. The Kappa is said to be able to walk upright like a human, and it always has a depression in its skull where it keeps water, which is the source of its power. The Kappa comes out of the water to enchant children and lure them into the river where it can eat them. This story is often told to children to scare them from getting too close to the water. According to this old print, a good fart will repel them.
