Description * 2-in-1 Design: A Rally Car and Tricycle in One! With 51 large and small parts, kids use a toy driver and wrench to twist and tighten pieces together to build a rally car — and the same parts can be reassembled into a tricycle! Building step by step helps children develop focus, while creating something new on their own boosts creativity. * Learn About Rally Cars Through the Storybook "My Friend Rally Car" tells the story of a rally car that rushes to help a friend in danger during a car race. Rally cars are specially modified racing vehicles with sleek, well-balanced wheels built for long-distance endurance. Through the story, kids naturally learn about long-distance races and the unique features of rally cars. * Enjoy Role-Play with Your Own Custom Car What kind of car will you build to join the long-distance race? To handle off-road terrain, the wheels need to be tightly secured and the body needs to be extra sturdy. Become a race car driver and take an exciting drive! With just one rally car kit, kids can build not only a tricycle but also try creating other new vehicles. Playing pretend with a car they built themselves helps nurture curiosity and imagination. * Easy to Build with Video Guides The "My Friend Rally Car" storybook includes instructions for building both the rally car and tricycle.
