Product Description Kids can 'drive' and role-play with the LEGO Super Mario 71431 Bowser's Muscle Car Expansion Set. This buildable toy car for kids who enjoy creative play will make a great addition to any LEGO Super Mario building toy collection. Please note the 71360, 71387 or 71403 Starter Course (each sold separately) is required for interactive play. This LEGO Super Mario collectible toy car has lots of playful features including a lever that makes the bonnet mascot move or trigger other tricks.

For interactive play, add a LEGO Mario, LEGO Luigi or LEGO Peach figure from a LEGO Super Mario Starter Course (71360, 71387 or 71403, each sold separately). Place one of these interactive LEGO Super Mario figures in the driver's seat of the race car toy for beeping-horn, running-engine and squealing-tyre sound effects and to earn digital coins.
