Children ages 4 and up can dive into the world of NINJAGO® Dragons Rising with Jay’s Dragon Mech Fight (71853), a beginner-friendly building set designed to help young fans learn to build while recreating exciting battle scenes from season 4 of the show. This set includes two fully posable mechs—Jay’s dragon-themed mech with an opening cockpit and movable wings, tail, arms, legs, and fingers, and the Mutation Monster’s mech featuring its own opening cockpit and articulated tentacles, arms, legs, and torso. To expand the action, the set also comes with four interchangeable weapons: two swords, a spear, and a pair of claws, allowing kids to swap gear and customize each battle.
With 107 pieces, this set is crafted for early builders and includes a helpful Starter Brick that gives children a strong starting point, boosting their confidence and making the building process faster and more enjoyable. The two included minifigures—Jay and the villainous Mutation Monster—let kids immediately jump into imaginative play, acting out good-versus-evil clashes just like in the show. Designed as both a fun play experience and a gentle introduction to LEGO® building, this set makes a great gift for young ninja fans and pairs well with other NINJAGO® mechs, dragons, and vehicles for even more adventure.
