Throughout their escapades in Toyland, Lisa drives a pink car, Mary drives a blue car, and Georgie drives a purple car. Jack's car changes between pink and blue constantly. For example, at the Toymaster's Workshop he parks a pink car, then leaves in a blue one.
At the beginning of the movie, in the toyshop, "Jack" (played by Keanu Reeves) says "My Jeep's got four-wheel drive, I'll take you both home." But when Jack, Mary and Lisa leave the toystore, Jack is driving a Suzuki Samurai.
