Kids ages 6 and up—as well as fans of the NINJAGO® Dragons Rising TV series—can jump into action-packed adventure with the LEGO® NINJAGO Kai’s Dragon Mech Battle Pack (71851). This compact set includes a fully posable dragon mech featuring movable legs, large wings, clawed hands, and a 360-degree rotating upper body. A cockpit is built into the mech so kids can place a minifigure inside and recreate dynamic scenes from season 4 of the show. The set also includes three minifigures—Kai, Sora, and a fearsome Earth Monster—each equipped with weapon accessories to spark imaginative good-versus-evil battles.
With 85 pieces, this build offers a quick yet engaging building experience, making it a great value gift for kids who love fantasy play and ninja-themed toys. The LEGO Builder app enhances the process by letting young builders zoom in, rotate models, and track their progress using step-by-step digital instructions. As part of the larger NINJAGO® universe, this set pairs easily with other mechs, dragons, and temples, giving children endless opportunities to expand their imaginative play and create epic ninja adventures.
