Domo’s bone structure is very simple. It has one big head bone, rib cage, backbone, pelvic bone, hands and legs bones. There is something very interesting about Domo-kun is it has no fingers, but has four toe bones in each leg. However it is not visible from its exterior body. Domo-kun must have very strong body muscles to support the big head. The 9″ Domo Skeleton Plush features its skeleton which glows in the dark.
