Japan: Hyosube

http://lorekeepersinn.blogspot.com/

The short, humanoid demons are tiny, belligerent, and bad news. If you see one, you will die — and they are more than happy for you to see them. They don't try and hide, they wander as they want. And they'll eat all the eggplants in your garden, and trample your field just to be assholes. About the only thing you can do to avoid accidentally seeing a Hyosube is leave some eggplants out for them willingly, and even that's a 50/50 shot at best. Oh, and sometime Hyosube will use your bathtub, leaving behind a huge amount of dirt, hair and scum. If you throw out the bathtub water, the Hyosube will fucking kill you. Just buy a new tub.
