Moomintroll (Swedish: Mumintrollet) is the main character in the Moomin books by Tove Jansson. He lives in the Moominhouse together with his father Moominpappa and his mother Moominmamma and has a keen spirit of adventure. Moomintroll is a 'moomin' - a little white troll with a hippopotamus-like big round nose. He is very kind and well-meaning, but in the comics he is usually more unhappy or annoyed than in the novels.
