71857

LEGO Ninjago 71857, Ninja Vehicle Tree House Battle, is a 2026 set built around a tree house battle with ninja vehicles. It belongs to the Ninjago theme and contains 647 pieces.

This set sits within the Ninjago theme as an action scene rather than a single standalone vehicle. Its title, Ninja Vehicle Tree House Battle, points to a central tree house build combined with ninja transport and opposing characters, giving the model a clear setting for conflict and movement.

The set has 647 pieces and 6 minifigures listed by Rebrickable: Acid Monster, Tail, Zane, Shoulder Armor (Draconus Robes), Loyalist, Kai (Draconus Robes), Jay (Draconus Form), and Euphrasia. The French retail title also refers to a motorcycle, a helicopter, and swords, so the contents can be described as a mix of scenery, vehicles, figures, and action accessories.

It is likely to appeal to Ninjago collectors who want named characters and a complete scene, as well as builders looking for a play setup with both a location and vehicles. In the wider theme, it fits between a location-based set and a vehicle-focused set, offering a compact narrative framework for display or role play.
