No bones about it, builder ZiO Chao knows their LEGO anatomy! Their impressive hybrid of System and Technic parts gives us a peek into our innermost core while still providing quite the possible finished model. The cranial crafting here is spot on, with an excellent pair of eye sockets and two dazzling rows of 1×1 plate teeth. And at the opposite end of the model, Mr. Skeleton’s feet are well-crafted. I particularly like the detail of a distinctly larger hallux, or “big toe,” compared to the rest of the foot. And the use of the robot arms for the metatarsals gives each pedal construction the perfect arch on their underside.
