What Makes this set WOW?

+

Interactive diorama base: The moss is mounted on a sea base with monster tentacles, from which it can be easily detached, which perfectly combines an exhibition and play function.

+

Possible cape with wire: The cloak made of fabric has a built-in wire, which allows it to be freely shaped and gives the model a dynamic effect, as if it were waving in the wind.

+

Advanced knee articulation: The design has fully movable knee and elbow joints, which allows for stable positioning of the almost thousand-piece mech in epic combat poses.

+

Exclusive Monstrosity Aesthetics: The set features a darker design and a unique Fire Master Kai minifigure, all complete with a first-in-Ninjago illustrated box.
