After some initial ribbing, Jimmy reveals that he's secretly created a device that can transport them to other dimensions. Timmy jumps at the chance to check out Jimmy's world, but when they arrive in Retroville, they quickly discover that all is not well.

It turns out that Jimmy's arch-nemesis, Professor Calamitous, has teamed up with Timmy's own frenemy, Crocker, to build the ultimate weapon: The Jerkinator. This massive robot is designed to take over the world, and it seems like nothing can stop it.
