Heavy Armor Ox (Qiji 3602)

About this set

This is KEEPPLEY 3602 Heavy Armor Bull from the Nucleus Crystal Youth series: 252 pieces, marked 6+, difficulty 2/5, and a four-legged mechanical beast in orange, black and grey. The head carries horns, so build the four legs first and check that they sit symmetrically at the same angle before attaching the body, since fixing leg alignment later is awkward. It is a 2-in-1 transformable model, switching from quadruped beast to mecha form, and the transformation needs care at a few connection points. With a modest part count and straightforward clutch, it suits newer builders and mecha fans who want to try a transforming structure.
