Strawberry’s friend Coco Calypso lives on Seaberry Beach with her pet, Papaya Parrot, and a band of fun-loving monkeys. When the seaberries that Coco harvests from the sea are stolen, she asks Strawberry, Rainbow Sherbet and Blueberry Muffin to solve the mystery. Setting a trap, they think they’ve caught a mermaid – but it turns out to be a shy girl named Seaberry Delight, who lives in a grotto in the lagoon. Seaberry grows the berries, and she thought Coco was stealing the berries from her! With Strawberry’s help, Coco and Seaberry learn to share the berries – each making a new friend in the process.
