Here we get to meet all the familiar characters from Moomin Valley - Moomindad, Moominmamma, Filjfonkan, Too-tick, Snusmumriken, Hemulen, Snorkfröken and of course the Moomintroll herself. For a whole year, we get to follow life in Moomindalen. It all starts when the Moomintroll, who is supposed to be sleeping this year, wakes up from his winter sleep and sets out on a journey of discovery.
