These are clay idols of Great Cthulhu, the "fictional" octopus-headed god from the stories of H.P. Lovecraft. They are meant to be the sort of primitive religious object a typical Cthulhu cultist might keep around the house for day-to-day worship rather than representations of Great Cthulhu Itself.
