DIO's Bone

The term DIO's Bone (DIOの骨 DIO no Hone) refers to a bone belonging to DIO, entrusted to Enrico Pucci before the events of Stone Ocean.

Summary
After Pucci enlists Sports Maxx's power to bring it back to life, the bone becomes infectious. Anyone who touched it would mutate, slowly germinating until becoming a sort of plant.

Thirty-six convicts of Green Dolphin Street Prison were infected by the bone, and the nutrients they absorbed from sunlight eventually formed a baby-like creature referred to as the Green Baby.

The Green Baby then sought out Pucci, and, upon finding him, fused with his Stand in order to create C-Moon.
