The Muddler is an anxious, scatterbrained collector who chooses to live in a coffee tin. He stores away all the buttons he finds, but is hopelessly careless with his collection. The Muddler is always forgetting and losing things.
The somewhat shy Muddler has a tail, wears a pan on his head and dresses in ragged clothes. The Muddler met his wife, Fuzzy, while on an adventure with Moominpappa. Sniff is their child, although he lives with the Moomins.
The Muddler, who is a nephew of the inventor Hodgkins, appears in the book Moominpappa’s Memoirs.
