The forest ranger's residence is a tiny enclave of human civilization situated inside a sizable nature reserve in the middle of an uncharted wilderness. As the bear Grizzy believes he is the most advanced animal on the planet, he believes it is only fitting that he take over the ranger's house as soon as its occupant leaves. The Lemmings are the only family of mammals that dares to challenge this "bear's privilege"; they move into the house as soon as the ranger leaves, making them the most insensitive, foolish, and idiotic mammals in existence.
