About this set
This is LEGO 71839, Arin's Phantom Spinjitzu Battle Mech from the NINJAGO line, marked NINJAGO DRAGONS RISING on the box. At 213 pieces and a 2/5 difficulty, it is a light build that works well as a first NINJAGO mech for anyone new to the theme. The finished model is a large mech in gold, black, pink and blue, built as a golden dragon two-legged mech: the two-foot stance carries the bulk, the head-mounted cockpit lets the pilot drop in from above, the right hand holds a scythe, and a long-handled weapon sits on the back, so the silhouette reads from both front and rear. When building, lock in the legs and weight-bearing joints first, then add the torso and head-mounted cockpit, and attach the scythe and back weapon last so the stance stays level and parts do not pop loose during later pressing. Gold dominates with black edging, while pink and blue act as accents; on a shelf the head-mounted cockpit and hand-held scythe do most of the identifying work. It suits NINJAGO mech fans who want a quick two-legged mech from a couple hundred pieces, and works as a warm-up before MOC builds in the same theme.
