Kabouter (Dutch)
Kabouter is the Dutch word for a type of little people, similar to a gnome or leprechaun. In folklore, the Dutch Kabouters are akin to the Irish Leprechaun, Scandinavian Tomte or Nisse, the English Hob, the Scottish Brownie and the German Klabauter or kobold.
In the folklore of the Low Countries, kabouters are tiny people who live in or near houses and stables, or in forests. In modern children's stories, they live in mushrooms. This is different from gnomes who live underground. They are also spirits who help in the home. The males have long, full beards and wear tall, pointed red hats.
