Wicked Science

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.

Charming, manipulative new student Jack befriends Garth so he can gather information about the shrink ray which he saw Garth use to shrink the giant doll. Garth is initially so impressed by Jack's friendly overtures he rebels against Elizabeth, but not for long. Elizabeth, distraught when Sacha beats her by one percent on a science assignment, seeks revenge and invents a 'Dream Catcher'. Elizabeth turns dreams (or nightmares) into reality when Sacha loses all her teeth in front of the class, while during a volleyball match, Garth grows breasts. Both have to deal with these confronting problems and Garth surrenders, swearing allegiance to Elizabeth, telling Jack they can no longer be friends. Thanks to some quick work by Toby, Sacha arrives in class ready to present her assignment with a gleaming smile.

Toby has his eye fixed firmly on Jack's sister Nikki. He is desperate to impress her, but how? Given she's a swimming star, he decides his best chance is to get on the school swim team. There's only one problem, Toby's a pathetic swimmer! Toby uses wicked science to invent a body oil to help move through the water like a seal. This threatens Garth's tenuous position on the swim team and when Elizabeth learns what Toby's up to she intervenes, tampering with Toby's oil. At Toby's next race, the new 'oil' causes him to behave like a performing a seal, embarrassing him in front of the whole school and more importantly, Nikki. He realizes he should never have used 'wicked science' for his own selfish reasons and, even worse, he might have lost Nikki for good.

Elizabeth catches a bad cold from Verity. With a raging temperature, her power to hyper-function and use her genius is out of control. She finds herself acting against her will, fulfilling other peoples' wishes - a cold cream for Verity, sunglasses which give Russ scientific formulae and an exo-skeleton for Garth, transforming him into an armored warrior Garthdor. The illness worsens and Elizabeth, close to death, calls for the only person who can save her - Toby. He hyperfunctions just in time to save Elizabeth's life, and although she takes it as a sign he cares about her, Toby is still firmly focused on Nikki. Meanwhile Russ and Sacha have to deal with an out of control Garth in the Surf Cafe and only just prevent Jack from seeing more wicked science in action. But he sees enough to suspect the two trios have access to something special and he wants 'in'.

Trying to help his friend, Russ finds himself forced to masquerade as Toby at a meeting with Nikki in the surf cafe. Wearing a Toby invention - a hi-tech polymer vivo interface suit (which makes Russ look and sound exactly like Toby) Russ might look like Toby but he's still Russ and clumsy. He knocks the suit's controls resulting in a malfunction, causing Russ to chaotically transform into multiple identities in the middle of the Surf Cafe. Sacha runs damage control but when the real Toby turns up the fight to keep his invention and therefore his genius a secret becomes more difficult as a curious Jack gets closer to the truth.

When Russ is bullied by Garth, Toby tries to prove Russ is not a loser. Toby creates a time portal to show Russ his ancient, valiant ancestors. But things go horribly wrong. The time machine is damaged and Russ finds that he's swapped places with his 350,000-year-old hominid ancestor, Rog. While the caveman battles with Garth at a twenty-first century school, Russ is hailed as leader of a tribe of cave-dwelling hunter-gatherers. Eventually, Toby repairs the time machine and Russ, the inventor of the 'Cro-magnon pizza', returns to present day more confident and assured but Toby and Sacha are exhausted after a day of minding a donut loving Rog.
