The adventures of four penguins—Skipper, Kowalski, Private, and Rico, who perform various commando-like missions to protect their home in the Central Park Zoo. The penguins often have to deal with problems caused, or made worse, by their zoo neighbors, King Julien XIII (a ring-tailed lemur), Maurice (an aye-aye), and Mort (a mouse lemur).

Julien and Maurice fight over a camera that fell from the sky.

Frustrated by their obnoxious lemur neighbors, the penguins decide to take a vacation... to the moon.

The penguins leap into action when a spooky noise frightens Marlene.

The popularity of stuffed Mort dolls causes Julien to sabotage the toys, prompting a recall.

Maurice bribes the animals with candy so they'll celebrate "King Julien Day."

Marlene discovers a lost egg and thinks the Penguins would be perfect egg watchers.

When Skipper steals Julien's radio batteries, a wild chase gets them stuck in a kangaroo pen.

Julien challenges the penguins to play Capture the Flag, but the lemurs win every time.

Julien can't take Mort's obsessive feet touching, so he exiles Mort from the lemur habitat.

When the zoo installs web cams to bring in new visitors, Private accidentally becomes an Internet star.
