Get ready to race through Bowser's Castle! The LEGO Super Mario: Mario Kart – Bowser's Castle (72039) building set brings one of the most iconic Mario Kart tracks to life with all the chaos and excitement that fans love. Young gaming fans ages 9 years old and up can build the legendary castle complete with foldout walls, a spinning Fire Bar, and a menacing Thwomp ready to crush anyone who gets too close! Kids can race the Bowser figure in his Standard ATV and the Yoshi figure in his speedy Mach 8 kart, launching shells and drifting around tight corners just like in the Mario Kart series. The castle features authentic details that Mario Kart fans will recognize, including space for Bowser to stand on top of like the ultimate boss, and destructible walls that racers can smash right through. Kids can place interactive LEGO Mario, LEGO Luigi, or LEGO Peach figures (from sets 71439, 71440, 71441 or 72043 – each sold separately) in either kart to trigger authentic Mario Kart sound and visual effects that bring the digital racing experience into the real world. Set up epic Bowser vs. Yoshi showdowns, dodge the plunging Thwomp, and topple the Lava Bubble for endless racing adventures. This building set is perfect for kids who love the Mario Kart series, building toys, and action-packed pretend play. Young builders can combine this set with other LEGO Super Mario: Mario Kart sets (each sold separately) to create an entire Mario racing universe. The LEGO Super Mario app provides step-by-step digital instructions to guide construction. Contains 1,068 pieces.
