Four New York City zoo animals - a lion who's used to being the centre of attention, a zebra who wants to live in the wild, a giraffe who's a hypochondriac, and a hippo who's got attitude to spare - are taken from the comfort of their homes and loaded on to a boar headed for Africa. Destination: the wild! But instead they end up shipwrecked on the island of Madagascar, surrounded by the locals. Can the four survive in the wild without going crazy?
