The Penguins of Madagascar is a spin-off TV series of Madagascar.
The series' new protagonists are Skipper, Kowalski, Rico, and Private. Characters who have returned are King Julien, Maurice, Mort, and Mason and Phil. New characters include Marlene the otter, Dr. Blowhole, Alice, and more.
The series follows the adventures of the four penguin protagonists: Skipper, Kowalski, Rico, and Private, who perform various paramilitary missions to protect their home in the Central Park Zoo. The penguins often have to deal with problems caused (or made worse) by King Julien XIII, Maurice, and Mort.
Some of the actor who played the characters in the films didn't reprise their roles. Chris Miller is replaced by Jeff Bennett as Kowalski, Christopher Knights is replaced by James Patrick Stuart as Private, Sacha Baron Cohen is replaced by Danny Jacobs as King Julien, and Cedric the Entertainer's character is now voiced by Kevin Michael Richardson. In three episodes, Andy Richter was replaced by Matt Nolan as the voice of Mort (although Richter voices Mort for the rest of the series).
