Description
Lloyd and his mech
The set centres on Lloyd, the Green Ninja and one of the core characters in the Ninjago story, here paired with a mech that, going by its name, is built for combat in or around water. With 2 minifigures included, there is enough here for a small stand-off scene between the mech's pilot and an opponent, rather than just a single static model. Mech sets like this one are a well-established part of the Ninjago range, usually combining a minifigure with movable elements such as arms, claws or weapons that can be controlled by hand.
104 parts for a detailed build
Out of 228 pieces total, 104 are unique shapes, a high ratio that points to a fairly detailed model with plenty of specialised parts, likely for joints, weapons or the mech's frame itself. The full parts list on this page breaks down exactly which shapes and colours are used, handy for anyone hunting for specific Ninjago pieces. The overall size of the mech build is likely shaped by its many specialised parts, since joints and connecting pieces often rely on shapes that are used less often elsewhere.
Colours between technical and camouflage
Black along with light and dark grey form the mech's technical framework, while sand green adds an unusual, muted accent that fits the set's water or camouflage theme. That combination sets it apart from the bolder red and gold tones that dominate many other Ninjago sets. Water-based storylines recur throughout the Ninjago narrative, often putting the ninja in situations where they face opponents on or beneath the water.
Where it fits in a Ninjago collection
At 228 pieces with 2 minifigures, this set sits in the middle of the Ninjago size range, larger than the smallest sets but more compact than the big vehicles or bases. That makes it a sensible addition to an existing Ninjago collection, particularly for fans of Lloyd or water-themed mechs. For fans specifically collecting Ninjago mechs or vehicles, this set is a natural addition alongside Lloyd's other well-known builds.
