Despite his office, the Mayor apparently has very little actual authority in the day-to-day running of the town, especially in planning for Halloween. This is attested when he arrives at Jack Skellington's house to discuss some plans with him, not knowing that Jack is not home. When Jack does not answer, the Mayor quickly gets hysterical and yells, more to himself than anyone, "Jack, please, I'm only an elected official here! I can't make decisions by myself!" Nonetheless, the Mayor seems to enjoy his position. He apparently owns the only automobile in town: a hearse-like car called the "Mayor-mobile" that is equipped with a loudspeaker for making announcements and a black, cat-shaped hood ornament that sounds a siren when its tail is cranked.
The Mayor is rather short, especially when compared to Jack. His head is cone-shaped and displays the two faces he is most notable for. One face (as well as his hands) is peach-colored, with rosy cheeks and a face set in a permanent smile. The other face is bone-white, has a mouth set in a permanent frown (the teeth of which are pointed) with green lips and yellow eyes. There is an seam of some sort around the mouths of both faces because in the claymation for the movie, the mouths were replaceable to make the mayor talk. His top hat is gigantic, being the same height as the Mayor himself, but very thin. The Mayor's body is also cone-shaped, with his body ballooning outward before ending on short, stubby legs with very tiny feet. He dresses in a black suit with a white undershirt and black-and-white pinstriped pants. He wears a pendant or bow-tie shaped like a black widow spider, though it only has six legs and the notorious red hourglass marking is on the spider's back and is much more detailed than in real life. There is a red ribbon with the word "MAYOR" printed on a white center pinned to the left breast of his blazer. He is never seen without his short, metal megaphone that he uses to issue orders, announcements, and, more often, call for help from Jack.
