Nopperabo - Japan

Nopperabo looks like a normal person until you come face to face with it, usually on quiet, empty roads at night. When you meet a nopperabo, you see that it has no face, only a blank canvas. Sometimes, several nopperabo will work together to scare a human, the first scaring the person, and the second impersonating a friend. When the person is scared and runs to tell their friend what happened, the nopperabo will ask "Oh, you mean like this?" and reveal themselves.
