Three.Two.One is designed to adapt to the three stages of childhood.
A young child can play with the car by pushing it along. As the child grows, a balloon can be attached which can be inflated and released to create a self-propelled car. Finally, the car can be transformed into a racing car by adding a rocket engine to it.
These adaptations allow the car to be kept by the same individual as they grow, until it’s time to pass it on to the next generation.
