The Ancestor
The Ancestor is a small, furry and grey troll with a large snout and a long black tail. It does not speak or eat. In Moominland Midwinter Moomintroll releases the Ancestor from a cabinet in the bathhouse and gets acquainted with it. The Ancestor moves into the Moominhouse and refurnishes the entire house one night, building a small home for itself around the tiled stove. According to Moominmamma, the ancestors used to live behind tiled stoves.
