Three little bears set out, on a dark night, to explore a mysterious hollow tree and, once inside, make surprising discovery after surprising discovery.
Concerned that the family is spending too much time in front of the television and neglecting other activities, Mama Bear decides that there will be no television watching for one week.
When Mama Bear decides that the family has accumulated too many old toys, books, and games, they sort through all their extra stuff and take it to the Old Bears Home, the Beartown Children's Hospital, and the Bears-Who-Care store.
As Mother's Day approaches, Papa Bear and the cubs do their best to surprise Mama with breakfast in bed and a gift, and Mama does her best not to ruin the surprise.
