The Moomins are the central characters in a series of books by Finnish writer Tove Jansson,
originally published in Swedish. They are a family of
Scandinavian trolls who are white, round and furry in appearance, with large snouts that make them resemble hippopotamuses. The carefree and adventurous family live in their house in Moominvalley, though in the past their residences have included a
lighthouse and a theatre.
