LEGO 71427 (retired 2024) is a large LEGO Super Mario expansion set that lets builders create two enemy airships (Larry’s Airship and Morton’s Airship) from the Super Mario games and add them to a customizable LEGO Mario course. It focuses on aerial battles featuring two Koopalings. The set comes with three buildable enemy figures: Larry Koopa, Morton Koopa Jr. and Goomba. These enemies can be defeated during the interactive gameplay course. Players can place interactive figures like Mario, Luigi, or Princess Peach (sold separately) in the cockpits to trigger sound effects and gameplay when used with a starter course. 

The box is in mint condition. The set being sold is the same as the pictures shown.
