Description
About this set
Mario Kart: Wario & King Boo is a 512-piece LEGO Super Mario set with Wario’s Badwagon and King Boo’s Teddy Buggy. Both karts can drift and launch shells, and two traffic cones give you something to swerve around. The Badwagon’s glider comes off and fits on the Teddy Buggy too. Wario and King Boo figures are included.
Rated 8+, it’s for Mario Kart fans who want to race at home. Add an interactive Mario, Luigi or Peach figure, sold separately, and the karts trigger game sounds and effects. It has left production, so new sealed boxes are only getting scarcer.
Highlights
- Badwagon and Teddy Buggy karts
- Shell-launching and drifting on both karts
- Detachable glider swaps between the two karts
- Wario and King Boo figures plus two traffic cones
