"Fiery Crashes. Icy Mountain Roads. High Speed Leaps Over Rocky Chasms. Gosh, I Hope No One gets Hurt." "I've had some close calls. But this is crazy! In The Challenge of Racer X, you'll face danger two ways. First, you'll take on the mysterious Racer X in a 200MPH free-for-all. You'll need everything in the Mach 5's arsenal just to stay close... Autojacks to leap clear of danger, chopper-blades to cut through obstacles, even a new on-board CRT that allows you to receive messages from Pops, Trixie, Spridle and Chim-Chim. And that's just the half of it. You'll also race against me from the cockpit of Racer X's incredible Shooting Star. But it won't be easy. Because Snake Oiler, Captain Terror, and all the evil villains from my TV show are out to send you over the guardrails. So fasten your seatbelt. Because this adventure is so dangerous, we couldn't put it on T.V."
