Beaver named Norbert Foster needed to heat the winter shack where he lives with his younger brother Deggetom Doofus. To keep warm in the winter, it is necessary to circumvent the entire underground labyrinth and posobirat logs that he and his brother have prepared for the winter. These are not simple, because the wood had their eye on the inhabitants of the nearby village, and now they are trying to carry out their right under the nose of the beaver to drown them their homes. Most Norbert give away all his wood and bring them to his shack.
