When George hears about the annual boxcar derby, there's no way he's going to miss out. George enlists the help of his friend Allie to build the winning boxcar. But the race is starting in just a few hours, and even with the help of Bill's instruction manual, building a car takes a lot of work. It's a race to the race as they try to get all the right car parts in time to enter the competition. This adventure based on the Emmy Award-winning Curious George PBS TV show includes bonus activities to test the effect of gravity and help reinforce the names and functions of different car parts.
