Gideon calls the school board to report Principal Bradford for wearing inappropriate shorts to school. This angers Bradford who decides to get revenge after Gideon. He runs after Gideon on the hallways, hoping to hit him with a dodge ball. Gideon asks Phoebe and Max to save him but Phoebe makes it clear that Gideon knows they no longer have superpowers. So, Gideon hides in the locker. Phoebe tells Max that they could help Gideon by boosting his confidence so that he can stand up to Bradford.
To boost Gideon's confidence, Phoebe gives him a bracelet and lies to him that it's a superpower bracelet that she used to boost her strength when she was a superhero. Gideon is easily convinced. Since Bradford is currently the temporary P.E. teacher, he singles out Gideon so that he can hit him with a dodgeballs. He's even got a dodgeball cannon with lasers to make sure that Gideon gets the maximum impact. Max uses telekinesis to help Gideon escape the dodgeballs from Bradford. This convinces Gideon that the bracelet gave him superpowers. Gideon refuses to give the bracelet back and declares himself a superhero called, The Giddler.
The Thunder Twins agree that it's a bad idea to mislead Gideon into thinking that he has superpowers because he could easily get hurt. So now, they must keep following him and saving him until they can figure out a way to get the bracelet back. Both Phoebe and Max get exhausted and both have "tele-cramps" following a day of actively using their telekinesis to save Gideon. So, while Gideon is at a hip-hop dance class, the twins come up with an idea to steal the bracelet back by pretending to be supervillains. Max offers to get the costumes. He gets himself a Scuba Boy costume and gets Phoebe a Donut Girl costume. Phoebe then sends Gideon an anonymous tip about evil equipment stealing villains at the Hiddenville High gym.
Gideon finds the "villains" stealing equipment at the gym. Before they get a chance to steal the bracelet back, Gideon sprays their eyes with spray cheese and runs to call Bradford. Phoebe and Max use the opportunity to telekinetically levitate each other up towards the roof. When Gideon returns with Bradford and finds no one, Bradford accuses him of lying. While Gideon is still trying to prove that he's telling the truth, Phoebe and Max (still disguised) accidentally fall on the floor after losing their telekinesis concentration. They quickly steal the bracelet back and run out of the gym.
Now that Gideon has lost his "superpower" bracelet, Bradford sets up his dodgeball cannon ready to hit Gideon. Phoebe and Max are tempted to come back to help Gideon one more time. They are surprised to find that Gideon has got the confidence to confront Bradford. Gideon gets hold of the dodgeball cannon and uses it to attack Bradford. The Thunder Twins watch from outside the door. They decide to help around by using telekinesis to attack Principal Bradford with as many balls as possible.
