Animal pals Alex, Marty, Melman, and Gloria are still trying to make it back to New York's Central Park Zoo. They are forced to take a detour to Europe to find the penguins and chimps who broke the bank at a Monte Carlo casino. When French animal-control officer Capitaine Chantel DuBois picks up their scent, Alex and company are forced to hide out in a traveling circus.
