When Sportacus reveals that he began his exercise regimen at a young age, Robbie Rotten invents a de-aging device that can turn a bird back into an egg and Sportacus into a 10-year-old. Now Robbie plans to raise Sportacus the lazy way, but even as a child, Sportacus is still active! With the help of the other kids, Sportacus heads to Robbie's lair to reverse the machine's effects.
This episode contains examples of:
- Raise Him Right This Time: Inverted. Robbie's scheme is to get the young Sportacus to be lazy, thus ruining his grown-up self's athleticism.
- Storming the Castle: Sportacus infiltrates Robbie's lair to be big again, with additional help from Pixel's hovercam.
