Sportacus gives the kids a step-o-meter to record how many steps they've taken in the day, turning movement into a game. Inspired by the kids' solar system hopscotch game, Robbie decides to move to the Moon for some peace and quiet—but when the kids decide to step on the Moon themselves with Pixel's energy-powered rocket, Robbie decides to head back to town. But when they mistake him for an alien, everyone may be in trouble when they get stranded on the Moon!
This episode contains examples of:
- Call-Back: Ziggy previously mistook Robbie for an alien in "Ziggy's Alien."
- Didn't Think This Through: Robbie realizes not only did he not think his plan to move to the Moon all the way through, he didn't think of a way to get back and has to hitchhike on the kids' rocket.
- Shown Their Work: The rocket Robbie uses to get to the Moon is portrayed extremely accurately as it leaves the atmosphere and lands on the surface.
