Lock, Shock, and Barrel

From Tim Burton's "The Nightmare Before Christmas". These are the three children who work for Oogie Boogie. Their names come from the phrase "lock, stock, and barrel". They kidnap Sandy Claws (Santa Claus) and take him back to Oogie's place. Lock is dressed as a devil, has a white face, blue lips, and red hair that resemble devil horns. He tries to be the leader, top dog, #1. Shock is dressed as a witch, has a long, white face, and stringy, wavy black hair. She is the leader (and the smartest) of the three. Barrel is dressed as a skeleton, with green hair, a white face, and a near-permanent ear-to-ear grin. Lock and Shock seem to underestimate him, and so becomes the butt of their jokes. They think he is "the dumb one". All three children have masks.
