Shock, Lock, Barrel, Sally and Jack

Halloween Town (or Halloween Land for areas outside the town) is a town in a themed universe entirely dedicated to Halloween. Jack Skellington, Sally, Doctor Finklestein, and other residents live there. Outside the town are a cemetery and the treehouse of Lock, Shock, and Barrel.

As its name suggests, Halloween Town brings Halloween to the real world every October 31st. Although its residents specialize in the art of scaring humans (and themselves!), it's their job, and they aren't evil, as the town's theme song, "This is Halloween," proclaims. It snowed once in Halloween Town, on December 25th, after Santa Claus gave them some before heading to the real world to restore order. However, it turned out that it had never snowed in the town before.

One day, as they were all meaning their own business at Halloween Town, Shock, Lock, Barrel, Sally and Jack all got teleported in a unknow room with a couch and TV in the middle of it all.

Sally (née Finklestein) is a supporting character in the film The Nightmare Before Christmas and the heroine of the novel Hail the Pumpkin Queen. She is a rag doll from Halloween Town. Intelligent and unassuming, she longs for independence but is constantly held back by Dr. Finklestein, her overprotective creator. She is also in love with Jack Skellington, the Pumpkin King.

Jack Skellington is a friendly skeleton, renowned for his honorary title of "Pumpkin King" in honor of the Halloween celebrations he hosts every year.

Lock, Shock, and Barrel (formerly known collectively as the Boogie's Boys). This mischievous trio of teenagers dress up for Halloween Town. They are between 17 and 19 years old.

Lock is the leader of the Oogie's Boys, but he doesn't always think things through calmly and actually seems to be only the second smartest, after Shock. Lock wears a devil costume: his teeth are sharp, his face is narrow with a prominent chin, and his hair is styled into two waxed horns, making him a, quite literally, handsome devil. His barbed tail is real and attached to his body.

Shock is the most cunning, the smartest, the most skeptical, and the only woman among Oogie's henchmen. She looks down on the other two for their supposed stupidity and often challenges Lock's leadership, but usually ends up obeying his orders. Shock wears a gray-pink witch costume and a long purple hat. Her mask is identical to her face, except for its green color and the lack of features (except for eye sockets and a nose). She usually rushes to calm arguments with the boys, even if her methods are not always the most elegant.

Barrel is considered the dumbest and clumsiest of the three troublemakers, despite his protests. He's the butt of many jokes from his friends, but he usually gets his revenge with his own pranks, which he always manages to pull off without a hitch. Barrel wears a skeleton costume and has deformed feet, , with white skin with a zombie mask.
