This object is about 6 inches tall. It has a squash-like shape and a non-symmetrical pattern of spikes. The entity inside the squash was made from a mold of a mask and the tentacles of some cephalopod monstrosity or Cryonex, the Elemental Prince of Evil Cold Creatures from the AD&D Fiend Folio.
Cryonex, Elemental Prince of Evil Cold Creatures. I believe the illustrator is Emmanuel. The AD&D Fiend Folio has long been a great inspiration to me.
