About Ninjago

Four easy-build ninja sets

Juniors sets relied on larger pre-shaped elements and short build stages, so a young child could finish a model with little help. The Ninjago entries follow the same idea while keeping the ninja-versus-villain setting of the main theme. Snake Showdown (10722-1) opened the run in 2016 with 92 pieces, alongside Lost Temple (10725-1), which at 172 pieces is the largest of the four. Shark Attack (10739-1) followed in 2017 with 108 pieces, and Zane's Ninja Boat Pursuit (10755-1) closed things in 2018 with 132 pieces.

A first step towards bigger builds

The minifigures fit straight into regular Ninjago sets, which makes these a gentle start before larger models. If a second-hand set looks incomplete, its parts list shows exactly what belongs in the box.
