The Finn Family Moomintroll awakens from a long winter's sleep and embarks on a whole new set of adventures, including the discovery of a magic top hat that can turn anything or anyone into something else.
Busy Bear wants to play all winter long with his animal friends despite what his mother says about sleeping, but when he becomes overly tired, he begins to realize why bears need to hibernate.
Every autumn a bear shows up behind the farm, and goes through a series of routines before finding a den among the hilltop boulders where he sleeps all winter long.
Bear notices that winter is nearly here and hurries to tell Snail, after which each animal tells another until finally the already sleeping Bear is awakened in his den with the news.
