They decide tjhat their new son's name should be Zim, although Dinky is actually a female. Dinky destroys everything she sees and wrecks Zim's base. "Old" Zim returns, wearing Hobo hair to look like Dinky. He confronts Dinky and manages to subdue the beast, then poses as the badger-monkey in order to get close to the RoboParents.

The Overtrouser tells Dib that his race was drifting around in their damaged spaceship until Zim contacted them and offered to help in exchange for disposing of the infestation of humans.
