The animated film "Madagascar" introduced audiences to a group of hilarious animals, and among them, the most laugh-out-loud funny are undoubtedly those penguins. Alex the lion, voiced by Ben Stiller, once gave a brief assessment of the penguins: "Penguins are crazy!" This is a memorable line from the first "Madagascar" movie. Based on the animated film "Madagascar," the animated TV series "Penguins of Madagascar" aired on Nickelodeon in the first half of 2009. The four penguins—Skipper, Kowalski, Rico, and Private—return to the Central Park Zoo in Manhattan for new adventures. Another pair of characters from "Madagascar," the eccentric King Julian and the lemur Maurice, also make new appearances, with the most notable being King Julian’s constant and frenzied clashes with the penguins.
