When plans to see the animals of Madagascar at the zoo are cancelled, Benny's disappointed and bored. He mopes in his treehouse until, to his amazement, he embarks on a bubble gum balloon ride that takes him to a far more exciting world than home. Despite a day full of tropical trapeze fun with lemurs, blend-n-seek with chameleons, and twittery tunes with birds, Benny is tired, hungry and remembers he never told mom where he was going. After silly starts and messy attempts, can Benny figure out a way to get home or did he never leave?
