Monster Jam fans aged 7 and up can explore so much with this LEGO Technic Monster Jam Dragon (42149) pull-back truck. This monster truck for kids features realistic graphics and colors, and cool dragon details like spikes and horns. This versatile racing toy lets kids recreate scenes from the Monster Jam arena. When kids are ready for a different vehicle, they can rebuild this LEGO Technic 2-in-1 Monster Jam truck into a Crocodile Buggy. Using the pull-back motor, kids can race their off-roader, recreating stunts they’ve seen in the real-life Monster Jam arena. The LEGO Builder app makes building even more fun; while kids build the toy car, they can view the models in 3D and track their progress. LEGO Technic building toys introduce children to the world of engineering in an accessible and realistic way. As they play, they explore the mechanisms and realistic movements of the buildable models. This awesome 2-in-1 pull-back car is a great birthday gift idea for kids who can't get enough of cool vehicles.
