Cthulhu Christmas Tree Ornament H. P. Lovecraft Xmas Alien Hanging Holiday Instead of "Joy to the World," the Cthulhu Ornament says, "Destroy the World." The representation of chaos and destruction from HP Lovecraft's stories is 4-3/4" (12.1 cm) tall, made of plasticized clay-dough and done up with a delightful festive Santa hat. Putting Cthulhu on your tree balances out all those happy ornaments you get from the mall. Comes with a string for hanging.
