This amazing behemoth of a pumkin, 1818.5 lbs, was carved by Ray Villafane. Villafane added pieces from a slightly smaller pumpkin, 1693 lbs, to create the emerging zombies. You can find his work on his website here. Or just watch this video about the process; I'm impressed. Oh, and Happy Halloween!
