Diego's in an Australian Forest when suddenly he hears a cry for help. It's a koala who's stuck in the middle of the road, with a truck headed right for him.
A big rainstorm has hit the rainforest, and lots of animals need help from Diego and his family. In gratitude, the animals help repair the damaged Rescue Center.
Alicia and Baby Jaguar have been planting trees for the Tamarins, so they can move back to the forest. But when the Bobos accidentally block the cave's entrance, Diego sets out to find another way out of the cave.
