Pixel has invented an invisibility helmet so he doesn't have to eat or sleep all day, and when Ziggy experiments with it Robbie Rotten promptly steals it. While Stephanie turns her house into a cafe to make everyone a healthy breakfast, Robbie uses the helmet to humiliate Sportacus in front of his fans, with his ultimate plan being to stop him from saving the Mayor and drive out out of town. It's up to Sportacus and the kids to figure out who's behind the trouble, but how can they find what they can't even see?
This episode contains examples of:
- Call-Back: The invisibility helmet and Pixel's general plot are reminiscent of the problem in "Zap It!"
- Invisible Jerkass: Robbie spends the whole episode bullying Sportacus while invisible, making the kids think there's something wrong with him.
- O.O.C. Is Serious Business: Sportacus falling down multiple times sends the kids into a frenzy of trying to find out what's wrong with him and how to help.
