Life is good in the Central Park Zoo for four lifelong friends. Taking the lead in this wacky pack is Alex the Lion—the zoo's pride (pardon the pun) and joy. His sidekick, Marty the Zebra, is a dreamer who always has his striped head in the clouds. Their buddy Melman the Giraffe is a hypochondriac. (Hey, you’d be afraid of getting a sore throat if yours was five feet long, too.) Last but not least is Gloria--the hippest hippo who knows how to throw her weight around. When a gang of scheming penguins inspires a daring zoo break, this funky foursome trades their comfortable caged lifestyle for the adventure of a lifetime. Will they, and their friendships, have what it takes to survive in the wild?
