The exuberant Maisy Mouse and her friends fly up and away in a plane, passing Tallulah in her hot-air balloon and doing loop-the-loops in the sky while delivering a happy birthday message for Eddie's party.
Enjoying a day of sailing with her friend, Maisy anchors her sailboat on a beautiful blue lagoon, where she and Charley fish, snorkel, and watch the numerous beautiful underwater animals that swim nearby.
