Bone Hydra
A skeletal hydra that regrows heads from nearby corpses.
Five serpentine necks of fused bone rise from a central ribcage the size of a house. Sever a head and it collapses — only to reassemble from the bone-strewn floor moments later. The body is the true target, but reaching it means weathering the bite of every skull.
