The student body is in an uproar when the controversial S.A.T.T.Y. 9 tests are stolen by an assailant dressed as X's beloved mascot, Lobstee the Lobster. Fillmore and Ingrid are under pressure—they have only 48 hours to find the tests or Principal Folsom will have the entire school take the tests again.

During an undercover sting operation, boxes of band candy were accidentally discovered in the lake. The candy is traced back to the Red Robins, seemingly a school club in the same manner as Girl Scouts who make record sales of their award-winning taffy. In reality, the Robins strong-arm their competition, and the Safety Patrol have been trying to catch them in the act for a long time. Ingrid goes undercover as a Red Robin, but Vallejo isn't convinced she's the right person for the job and suspects something might go wrong.

Scooter thefts are up, and the Safety Patrol faces a challenge from student activist Derek Minna, who establishes B.A.G.A.S.T. (Boys And Girls Against Scooter Theft), a scooter and rollerblade equipped task force that he intends to ultimately replace the safety patrol. Fillmore and Ingrid trace the thefts to the Metal Shop and infiltrate the gang in an attempt to take down the culprits.

Something's down at the X Middle School Open—professional golfers are failing at games, and foul play is suspected. Normally, Fillmore would be all-up for an undercover job like this, but something in his past is making him hesitate.

The Ultrabox, the hottest new game system on the market, makes its debut at X, and everyone wants one—including "The Maestro," a gaming mastermind who will stop at nothing to get it. Fillmore and Ingrid track him down, but the Ultrabox is stolen while he's in custody. It looks like a copycat is on the loose.
