Wacky Races Forever is an unsold pilot for a spinoff of Wacky Races. Produced in 2006, it does not appear to have aired on television.
The Slag Brothers are in first place, but Professor Pat Pending zaps The Bouldermobile and takes the lead. The Gruesome Twosome unleash bats on The Convert-a-Car, causing it to crash. As The Turbo Terrific tries to pass them, Fido the three-headed dog pops out of The Creepy Coupe to stop it but it jumps over the dog and lands in front.
Parker Perfect gets a hologram call from his dad, Peter. Simultaneously in The Compact Pussycat, Piper gets a call from mom, Penelope. The parents ask their children to get along, to no avail. Peter tells Parker that Perfect Industries has built a new bridge on the racecourse, out of sleeping snakes, and Mr. Viceroy, his lawyer, confirms it. As the Perfect siblings bump fenders, they and the other racers enter the snake bridge.
Dick Dastardly and Muttley get a call from Viceroy. He says plans have changed, and to disregard the plan to drive a wedge between Parker and Piper because they're already at war with each other, and just to go win the race. Dastardly thinks Viceroy is speaking in code, and drives away from the finish line, pushing a giant cheese wedge toward the others. The snakes awaken and the bridge collapses. Parker pushes the turbo button, propelling The Turbo Terrific, the mass of snakes, and the other racers to the other side of the chasm, and up and over The Mean Machine, to win the race.
