A skull is a bone structure in the head which supports the structure of the face.
On Halloween, people wear skull masks, to fit their costumes, whether it's a Grim Reaper, Skull Girl, or just a skeleton costume.
Skulls or simplified images of skulls are also common images in Halloween decorations. Sometimes candy is shaped to look like skulls. For some related holidays, the skull is also a common image, like for El Día de los Muertos pastries.
