Snufkin is a character in the Moomin series of books authored by Swedish-speaking Finn Tove Jansson, appearing in six of the nine novels. He is the best friend of the series’ protagonist, Moomintroll, and lives a nomadic lifestyle, only staying in Moominvalley in the spring and summer, but leaving for warmer climates down south every winter. Snufkin wears old green clothes and a wide-brimmed hat he has had since birth. He lives in a tent, smokes a pipe and plays the harmonica. Snufkin has a great dislike for all symbols of private property and for authority figures such as the Park Keeper, and the many regulation signs and fences he erects. At one point he sabotages the Park Keeper by planting Hattifatteners in his garden, causing them to grow and drive him out. Snufkin prefers freely-growing foliage to fenced-in lawns. He keeps as few worldly possessions as possible, seeing them as a burden, and being happier keeping the memory of a thing than the thing itself. Tove Jansson based the character of Snufkin on her friend and one-time fiancé, Atos Wirtanen.
P.S. This 8-bit Snufkin is based on his character design in the 1990 Japanese-European anime television series Moomin.
