Niß Puk

A household spirit from Schleswig folklore, described as being as tall as a child between one and three years old, with a big head, long arms, and small bright intelligent eyes. It wears distinctive clothing including red stockings, a long grey or green ticking jacket, a pointed red cap, and soft slippers with which it shuffles rapidly at night. The spirit possesses supernatural abilities including covering huge distances in the shortest time with the help of its slippers, and its red cap can make the wearer invisible.
