Mario Kart™ – Baby Mario vs. Baby Luigi

Two iconic Mario Kart racers face off in this competitive balloon-popping challenge. Baby Mario drives his bright red Biddybuggy while Baby Luigi pilots his green Tri-Speeder, both ready for battle on the racetrack.

The 321-piece set includes buildable versions of both kart racers along with six balloons (three red, three green) that serve as targets for shell-launching combat. Each vehicle can fire projectiles to knock down the opposing team's balloons, creating an active competitive element beyond simple racing play.

Interactive Features

Compatible LEGO Mario, Luigi or Peach figures (sold separately) can drive either vehicle to unlock authentic Mario Kart sound effects including honking and drifting noises. This interactive functionality requires one of the starter sets 71439, 71440 or 71441 to activate the digital features.

Each completed vehicle measures over 5 cm high, 10 cm long and 7 cm wide, making them substantial enough for active play while remaining appropriately scaled for display. Designed for builders aged 8 and up, the set works as standalone play or integrates with other Mario Kart expansion sets for larger racing circuits.
