Sally is Jack Skellington’s love interest. She is a very pretty, loving, caring, and shy rag doll who told Jack that Christmas and Halloween shouldn’t be mixed. She is originally patched together by Doctor Finkelstein. Sally is the only one to have doubts about Jack’s Christmas plan. Although her creator attempts to keep her constantly imprisoned, she often manages escape by slipping him deadly nightshade, causing him to fall asleep. Nightshade is a flower that grows atop the grave of a dead witch, as seen before Jack’s first song which induces temporary somnolence upon consumption. This becomes essential to Sally managing to trick the Doctor and escape. Despite her makeshift appearance, Sally is a determined individual with a good feel for what is right. Fiona Apple provides the vocals for “Sally’s Song” on the 2006 special edition of The Nightmare Before Christmas: Original Motion Picture Soundtrack, while Amy Lee provides the vocals for “Sally’s Song” on Nightmare Revisited. She also appears in Tim Burton’s The Nightmare Before Christmas: Oogie’s Revenge.
