About this set

LEGO 71851 Kai's Dragon Mech is part of the NINJAGO line, with the box marked NINJAGO DRAGONS RISING. It comes in at 85 pieces and a 2/5 difficulty rating, so it is a quick build rather than a long session. The finished model takes a red dragon form rather than a humanoid mech, built mainly in red, yellow, grey and gold, with a round gold chest plate, bat-like wings, hook claws at the limbs and orange lava pieces worked into the body. Sort the red, yellow, grey, gold and orange lava parts before you start, then follow the manual from the torso and chest plate outward; build the wings and claws in mirrored pairs so the angles line up, since aligning those sections and seating the lava elements are the main fiddly steps. At this part count the clutch is straightforward and the model holds together well for play. LEGO Builder support is included. It suits younger builders new to NINJAGO, dragon-mech fans, and anyone who wants a small display piece finished in one sitting.
