🏷️ 71431-1•🎨 Super Mario•📅 2024•🧱 458 parts•Intermediate

Bowser charges into action with the LEGO Super Mario Bowser's Muscle Car Expansion Set (71431-1). This 458-piece build presents a formidable muscle car, purpose-built for the King Koopa. The set features a brick-built Bowser figure, including an Action Tag for interactive play. A functional lever at the rear of the vehicle controls the front hood ornament, allowing it to move or trigger tricks during play. When a LEGO Mario, Luigi, or Peach figure from a Starter Course (sold separately) occupies the driver's seat, the car generates authentic beeping-horn, running-engine, and squealing-tire sound effects, rewarding players with digital coins. This set delivers Bowser's signature vehicle for new Super Mario adventures.
