Mossy, an amazing turtle with a gorgeous garden growing on her shell, loses her freedom when Dr. Carolina, a biologist, takes her to live in her Edwardian museum. Visitors flock to see Mossy, but it is Dr. Carolina's niece, Tory, who notices how sad Mossy is living in a viewing pavilion. She misses the outdoors and her friend, Scoot.
Dr. Carolina finds a way to keep the spirit of Mossy alive at the museum. She invites Flora and Fauna to paint Mossy's portrait. Then she and Tory take Mossy home, where Scoot is waiting for her.
