Retroville is the city where the franchise is set. In the episode Stranded, there is a scene where Jimmy and his friends take off in the Hover Car for a trip to the equator. Following an argument between Cindy and Jimmy and a comment from Libby about how their disputes happen solely to hide their true feelings, a map animation that shows the hovercar's route can easily be traced back almost precisely to Austin, Texas. Looking at Jimmy’s watch you can see that Retroville time is 12:00 and so is Chicago time, which suggests that Retroville is located in the central standard time zone. The phone number of the Candy Bar, as shown by a receipt, has a 985 area code, which is located in southern Louisiana. Retroville is near a downtown area (as a possible reference to Sugar Land next to Houston). The city imposes a 4% tax rate, as seen on Mr. Giggle's invoice in the episode Hypno-Birthday To You.
