In the highly-anticipated sequel to “Madagascar,” Alex, Marty, Melman, Gloria, King Julien, Maurice and the penguins and the chimps find themselves marooned on the distant shores of Madagascar. In the face of this obstacle, the New Yorkers have hatched a plan so crazy it just might work. With military precision, the penguins have repaired an old crashed plane—sort of. Once aloft, this unlikely crew stays airborne just long enough to make it to the wildest place of all—the vast plains of Africa, where the members of our zoo-raised crew encounter species of their own kind for the very first time. Africa seems like a great place…but is it better than their Central Park home?
