Grandma Ruffman returns! Appalled by Ruff's manners, Grandma sends Rosario and Nina to learn proper table manners and how to plan a party from an etiquette expert. She also sends Willie to Florida to compete against Calvin the dolphin at the Living Seas Exhibit at Disney's Epcot Center. Willie must compete against Calvin in tests of jumping, swimming, and holding his breath. Willie learns about how the dolphin's anatomy and physiology are adapted to an aquatic environment. Then in a re-match, Willie must make some modifications to his body based on what he's learned.
