Pammee has the best ears in all of Greenit and can even hear sounds that are far away. Thanks to Pammee's great hearing skills, the friends were able to put a stop to Oops and Koops who were throwing garbage away in Greenit during the night. One day a gift arrives at Pammee's house. In the gift box there are a pair of small and round earmuffs.

The friends are listening to Chewoo's story about a sunken treasure ship at the bottom of Greenit's ocean. Yoohoo and his friends decide to look for the ship and they use Roodee's robot fish to lead the way. While on their treasure ship hunt they come upon many sick ocean creatures.

There is a lot of damage in Greenit after a dinosaur rampaged the village. Yoohoo's roof is damaged, Chewoo's house is missing windows, Pammee's water pipes are broken, and the lampposts are not working, so Lemmee has to be there each night to light the way. Everyone needs Roodee's help to fix all that is damaged. Roodee is so busy fixing everything that he doesn't even have time to eat.
