Driving along in the car with his family. Harry wishes they could go faster. Mom explains that their car is for getting places safely rather than racing. So Harry decides to go off into Dino World to see if his racing dreams can be realised there. They each have great fun building their own hotrod race cars, and then put them to the test. Even though Dino World is a world of possibility they learn that not every-where is ideal for driving really fast, but before the race is out they come across some excellent, high speed racing ground. The heat is really on as Steggy suddenly gains some extra power and comes up from the back to steal the victory.
