But when George and Violet come by and see what he’s doing, they want to make racecars too. Now it’s a race to see who will finish first, and they don’t take the time to do the work properly. And then they race to see whose racecar is the fastest. But will all of this racing lead to a disastrous crash? In the end, they string the remnants of the racecars and make a nice train. Tchoo-tchoo!
