Artist Amy L. Rawson is famous for her annual Cthulhu Christmas creations. This year, she’s adding a new creature from the Cthulhu mythos: the Shoggoth! And he’s not only a monster, he’s a snowman Christmas ornament!
Between the branches of every Christmas Tree there is a spot that cannot be filled with pretty glass, Santa Claus, or tinsel. In that space, that terrible place, only "shapeless congeries of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and un-forming as pustules of greenish light" will do. Shoggoths love Christmas. This one found a hat and a carrot, likely dropped by someone running for his life, and has taken the shape of a snowman as best it can.
