The series is based on the famous series of novels by Finnish author Tove Jansson. It follows the adventures of strange creatures called Moomins and their equally strange friends. The series features a continuous narrative within individual installments, which do not always align with the 13-episode division. The series is realized using the semi-flat puppet technique, with commentary.
