LEGO Ninjago Battle of Jay’s Dragon Mech set 71853 – building playset with minifigure(s)

LEGO Ninjago Battle of Jay’s Dragon Mech set 71853 recreates Jay’s dragon mech as a build-and-play model designed for children from about 4 years old. The themed set includes two mech figures and at least one minifigure, plus a selection of interchangeable weapons and accessories for action scenes and storytelling. The model combines display potential with hands-on construction play and provides a partly built baseplate to help younger builders start confidently.

Advantages

The set encourages step-by-step building skills with a starter base that simplifies early assembly and boosts confidence for young builders. Both mechs feature opening cockpits and multiple movable parts — including tails, wings, arms, legs and torsos — to enable dynamic posing and play scenarios. Interchangeable weapons expand play options and support narrative play tied to the Ninjago series. With 107 pieces, the set balances quick assembly with enough detail for imaginative battles and display.

• Beginner builders aged 4 and up learning construction basics
• Fans of the Ninjago series recreating scenes or creating new stories
