The Moomins are the central characters in a series of books and a comic strip by Swedish-speaking Finnish illustrator Tove Jansson, originally published in Swedish by Schildts in Finland. They are a family of white, round fairy tale characters with large snouts that make them resemble hippopotamuses. The carefree and adventurous family live in their house in Moominvalley, though in the past, their temporary residences have included a lighthouse and a theater. They have had many adventures along with their various friends.
Snufkin: Moomin's best friend. The lonesome philosophical traveler, who likes to play the harmonica and wanders around the world with only a few things, so as not to make his life complicated. He always comes and goes as he pleases, is carefree and has lots of admirers in Moominvalley. He is also shown to be quite fearless and calm in even the most dire situations, which has proven to be a great help to Moomintroll and the others when in danger.
