Kobold

Kobold (plural - Kobolds) - a sprite stemming from Germanic mythology and surviving into modern times in German folklore.

Although usually invisible, a kobold can materialize in the form of an animal, dolls, fire, a human being, and a candle. The most common depictions of kobolds show them as humanlike figures the size of small children. Kobolds who live in human homes wear the clothing of peasants and often inhabit dolls; those who live in mines are hunched and ugly; and kobolds who live on ships smoke pipes and wear sailor clothing.
