There is trouble in the air: a comet threatens to crash right into Moominvalley. What now? A sense of doom or a dance on the volcano? Moomin and his friends choose both. However, peace in the valley is disturbed not only by falling celestial bodies, but also by the visit from the "League for Duty and Community" and the commotion surrounding Moomin's "golden tail," which proves to be quite unpleasant. Five new adventures featuring Tove Jansson's lovable Moomintrolls, charming, anarchic, and full of vibrant joy for life.
