The adventurous story of two lovable trolls who take up residence in a small abandoned summer cottage and must face many adventures together with the dwarfs and animals of the forest. Wandering trolls settle down in winter, which means they need to find a place to stay. This time, Trip and Trap have been lucky: they have discovered a small cottage next to a larger farm where human children play in the summer. While these children spend the winter in the city, Trip and Trap make themselves at home. Everything seems made for them, and winter promises to be cozy. The first curious visitors from the area also arrive: Jacko, the squirrel, and Mons, the dwarf. Later, Trip and Trap also meet an entire family of forest dwarfs. So they are in good company. But soon, problems arise: a moose is injured.
