Totally Spies! Totally Party

From Wikipedia, Sam, Alex and Clover decide to room together in their "dream house." Life couldn't get cooler, until they've unwittingly made their home right above an Underground Secret Services Center. To prevent a catastrophic security leak, Jerry, the Center Chief has no choice but to take on them as special agents. http://en.wikipedia.org/wiki/Totally_Spies!_Totally_Party
