The King of Far Far Away has died and Shrek and Fiona are to become King & Queen. However, Shrek wants to return to his cozy swamp and live in peace and quiet, so when he finds out there is another heir to the throne, they set off to bring him back to rule the kingdom.
Alex, Marty, and other zoo animals find a way to escape from Madagascar when the penguins reassemble a wrecked airplane. The precariously repaired craft stays airborne just long enough to make it to the African continent. There the New Yorkers encounter members of their own species for the first time. Africa proves to be a wild place, but Alex and company wonder if it is better than their Central Park home.
While trapped on the island of Madagascar, the Central Park Zoo escapees receive a visit from Santa--crash landing on their territory and getting amnesia to boot! The animals must help Santa assume his rightful place in the universe, while King Julian laps up the opportunity for his subjects.
