Dora and Boots take preschoolers on an exciting underwater adventure to help save the mermaid's kingdom. Dora travels to the bottom of the ocean and finds a hidden treasure chest on Treasure Island.
When class pets Linny the Guinea Pig, Tuck the Turtle, and Ming-Ming the Duckling are left alone every day after the bell rings, they help other pets in trouble around the world with the help of a special phone.
Children will help Dora and Boots get Arco Isis, a shy rainbow, to Rainy Mountain so he can shine in the sky, find King Juan el Bobo's crown, get Mama Bugga Bugga home to feed her family and break El Mago's evil spell on King Popo and Queen Maria.
