Sally Skellington
A ragdoll in the movie The Nightmare Before Christmas. She is Jack Skellington's wife (according to context in the movie) and is one of the main characters. In the beginning of the movie Sally has feelings for Jack, and also has a terrible vision: that Christmas will turn out a disaster if Jack interferes. Sally's creator is a mad scientist names Dr. Finklestein, who insists Sally stays in their tower. However, Sally is very curious, and she escapes by using deadly nightshade, a potion that puts people to sleep.
Sally Skellington is very clever.
