Lego's Ken Block Hoonicorn V1 building set brings the viral custom Mustang to life with a detailed build that is made for hands-on play and display. Exposed velocity stacks, custom wheels, and the included Ken Block minifigure add to the action, while the Lego Builder app gives young builders a clear interactive guide in 3D. It is a fun way to build fine motor skills and keep the racing theme moving from the table to the shelf.
