This learn-to-build LEGO NINJAGO set allows children aged 4+ to construct and play with Arin’s Battle Mech, inspired by season 2 of the NINJAGO Dragons Rising series. The posable mech features a cockpit, articulated limbs, a rotating blade, and comes with a large sword accessory. The set includes two minifigures: Arin with a katana and the Wolf Mask Warrior with a sword for battle role-play. Additional play elements include a flyer with adjustable wings, a disc shooter, two spears, a crystal cave with a magic mallet, and a weapons rack holding two katanas. Designed for young builders, this 4+ set helps develop construction skills while encouraging imaginative storytelling. Other NINJAGO sets featuring dragons, mechs, and ninja characters are available separately.
