Shock is one of the three Trick-or-Treaters, or, "Boogie's Boys" as the Mayor says, even though she is a girl. But just like Lock and Barrel, she shows no actual allegiance to Oogie Boogie or to anyone else. They all go to where it seems the most fun to cause trouble. She is one of the three secondary antagonists in the movie.
She is the oldest, being ten years old and only slightly taller than Lock, though her hat makes her appear a lot taller. She's the most cunning and intelligent of the trio, coming up with the plan on how to kidnap "Sandy Claws". She often challenges Lock for leadership, but ends up following his orders anyway. She is usually quick to patch up any arguments between her and the boys, if not with the nicest methods.
On their first try they mistakenly take the Easter Bunny instead, which angers Jack, and are told to take the frightened Holiday Spirit back to his own world. They succeed on the second attempt on bringing "Sandy Claws" to Jack.
Shock has dark blue hair and she wears a purple dress and hat. She is the only one of the trio who wears a mask without a smile. She's the tallest and the thinnest of the three, her neck is quite long and her nose takes up most of her face.
