Wacky Races (1968 TV series) The series is sometimes mistakenly known as "Stop the Pigeon", after the show's working title and theme song. Both series ran for two seasons. 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, a teenage version of the Gruesome
Wacky Packages binders were also made for the "Postcards" series (the first with a red cover and the second with a yellow cover) and one three-ring binder was made for the "Halloween Postcards" series. One of the biggest draws of the "Postcards" and "Halloween Postcards" series was the inclusion of artist sketch cards, which feature original drawings by popular "Wacky Packages" artists such as Neil Camera, Smokin' Joe McWilliams, Sam Gambino and Brent Engstrom. "Wacky Packages Postcards" and "Wacky Halloween Postcards" were both sold exclusively through the Topps Online Store, but no new series of either one have been released since 2013.
