Sam's name originates from Samhain, the origins of Halloween itself. He is depicted as a child dressed in a Halloween costume, which consists of an orange set of pajamas, and a mask made of a burlap sack with buttons for eyes. Sam drags a dirty sack around with him throughout the film, but its contents are unknown, presumably candy; Although the blood stains on the sack and the cat screeching when he drags it down the stairs would strongly suggest otherwise. Despite his childlike appearance, it is established that Sam is more demonic than he appears, hiding a pumpkin-shaped head resembling a skull. Dougherty described Sam's head as a cross "between an embryo and a pumpkin". Quinn Lord, who plays Sam in the film, described his character as being a demon who was born in a pumpkin patch.
