시즌 2, 에피소드 1: It's the first day back at school after the holidays and the giant doll still stands in the school grounds as a reminder of the events which occurred at Sandy Bay School last term. A re-geniused Elizabeth shrinks the giant doll and interrupts the new Principal, Ms Hammer at assembly so she can wipe everyone's memory. Her plan succeeds except for Toby and Russ, who escape with their memories in tact. New boy in town, Jack Bailey sees the shrink ray in action and is determined to find out about what's going on. Russ and Toby's cousin Sacha discover Elizabeth's new high-tech lab, but it is booby trapped and they are turned into blowflies. Escaping Elizabeth they find Toby who is forced to re-genius himself to help them. Toby restores his friends to normal, and Sacha demands to know the truth about wicked science.
