Skeleton guard

1asset skeleton_guard "Skeleton guard" complexity=5
2// a toy-like skeleton guard: a big round skull with deep sockets and two glowing pupils, a chattering
3// jaw, a stack of hoop ribs on a knobbly spine, bony limbs with fat knob joints, a dented helmet with
4// a plume, a round shield on one arm and a rusty spear or sword in the other fist. It sways and
5// chatters at rest, clacks along on walk, and on rattle shakes itself to pieces (nearly).
