Dan'l receives a message from his old great great grand-uncle Scratch who wants help to save the oldest and tallest tree in the world, the "sun tree". Muffy, a young cousin of Dan'l's, resents their intrusion, because he's convinced the tree will die and wants all the animals living in it to save themselves by moving to a new home. Despite Kimba's and the animals' efforts, a storm blows over the old sun tree. But Kimba learns that life will renew itself.
