Kids can help their favorite ninja master land and sky! The LEGO NINJAGO Lloyd's Jet Mech (71845) building set puts boys and girls 9 years old and up in command of Lloyd's transforming fighter from NINJAGO Dragons Rising Season 3. This towering robot dominates ground combat with fully posable arms and legs, a protective cockpit, and twin sword accessories, then kids can completely reconfigure the same parts into a high-speed jet with sleek wings and roaring engines. Young fans can switch between epic ground battles and lightning-fast aerial adventures as they position the minifigures of Lloyd and Sora to team up against the Master of Decay Kur minifigure and his villainous ally minifigures of Tyr and a Spectral Dragonian Warrior. The epic ninja adventures continue as kids practice launching Sora's speedy flying motorbike for aerial support, or maneuvering the enemy's menacing specter dragon to create chaos across the sky. Each hero minifigure comes equipped with signature ninja weapons, and kids can help Lloyd use his special translucent reveal blade to decode the secret messages hidden on the villains' mysterious banner. Children will enjoy experimenting with both building modes as they recreate their favorite TV show aerial battles or imagine daring new adventures for the ninja crew. Perfect for solo building or creative storytelling with friends, this set makes an ideal birthday or any-time present for kids who love transforming building toys and the hit NINJAGO Dragons Rising TV show. Combines with other LEGO NINJAGO sets including the Thunderfang Dragon of Chaos (71832) (sold separately) for expanded aerial adventures. The LEGO Builder app guides young builders through intuitive step-by-step instructions with helpful 3D viewing tools. Contains 1,112 pieces.
