It's a bright, sunny day on the Mali-U campus. As Sam, Clover, Alex and Britney stroll across the quad, they suddenly hear a strange sound. "Woohp! Woohp!" To their utter shock and surprise, they look up to see a group of students doing what appears to be the officially sanctioned WOOHP workout routine! Incredulous, they ask what's going on. That's when Mandy and Mindy tell them: "Duh. It's only the latest workout craze!" When the girls tell Jerry what's going on, he's equally as surprised and concerned. How did the secret WOOHP workout become public knowledge? He sends the girls on a mission to find out. What they discover is Master Mario, a former WOOHP strength and conditioning coach, who claims to own the rights to WOOHPersize. In fact, he has a contract to prove it¿ and plans on taking his business venture global. Suspicious, the girls investigate further and discover his real intentions to create an army of agents to help him take out WOOHP. But stopping this guy is easier said than done because of his highly trained, mind-controlled legion of devoted followers. In a b-story, with the return of Britney, Alex's jealousies return.
