After watching his favorite adventure/mystery TV show, "C.C. Cruiser and the Hot Rod Squad", Timmy wishes his life was exactly like the main character's, along with a female assistant and talking car. Wanda becomes his assistant and Cosmo becomes a talking, green car named Carsmo. The place that they go to seek adventure is Fairy World, where they discover that Mama Cosma is missing. However, there is a note there that reads: BRIDGE 7:00 pm. They then go to the bridge, but no one is there. Juandissimo Magnifico appears and tells them that Mama Cosma was at one of the restaurants. They go there, only to find that she is not there. Jorgen Von Strangle appears and tells Timmy and his fairies that Mama Cosma was at her house playing bridge with him, but then his teddy bear goes missing, and they must go search for it. The episode ends with all five on a freeze frame.

To celebrate half day (which resulted from his parents idiotically mistaking him getting home early from school because it was only a half of a school day as an actual holiday), Timmy wishes for a machine that allows things to merge with other items to become half-human and half-object. When Crocker gets a hold of it, he accidentally merges himself with cheese, and he uses this power to capture Timmy's fairies.
