In 2006, the pilot for a spin-off series titled "Wacky Races Forever" was produced for Cartoon Network. The series depicted a roster of both new and returning racers competing against each other. Penelope Pitstop and Peter Perfect had married and created Perfect Industries, the corporate sponsor of the new Wacky Races, whereas their children Parker and Piper competed in the race. Other characters included the Slag Brothers, Professor Pat Pending (depicted here with a mad scientist personality), a teenage version of the Gruesome Twosome, and Dick Dastardly and Muttley (working for a new villain named Mr. Viceroy, who sought to steal Perfect Industries). The series was not picked up by Cartoon Network.
