Oogie Boogie is the sadistic, abusive and voraciously hungry Boogie Man, resembling a large burlap sack shaped like a starfish. Inside of him are thousands of bugs. His life revolves around gambling, and loves gambling with others' lives. He likes to torture people. He is also apparently "The Shadow on the Moon at Night" as the shadow shown on the moon was an exact replica of him. He also used to be the king of his own holiday, "Bug Day", which eventually fell out of favor, resulting in him moving to Halloween Town.
Ironically, Oogie has no skills for gambling; on three occasions he rolls snake eyes, and admits he has to resort to cheating - he slams his fist upon the table to shake the dice, resulting in eleven. He is also somewhat lecherous, as which is evident when he's easily distracted by Sally's bare leg. According to Lock, Shock, and Barrel, as well as some of his deleted song material, he is also very good at making a concoction known as Snake and Spider Stew, though it would seem he tends to use people as ingredients. He is a sadist who has his henchmen abduct people and bring them to his lair for him to torture and eventually kill and/or add to his Snake and Spider Stew.
