Alex (voiced by Ben Stiller), Marty (Chris Rock), Melman (David Schwimmer) and Gloria (Jada Pinkett Smith) hanker for a return to New York’s Central Park Zoo.

They leave Africa and head first to Monte Carlo to reunite with the penguins, where the gang has a close encounter with tenacious animal control officer Captain Chantel DuBois (Frances McDormand) and her scooter-riding cronies.

Alex and co seek refuge on a circus train and pretend they are performing animals.
