She and the other two ghosts insist she must leave the Beldam's world and go straight home. They also ask her to find their eyes so they too can escape.
The Tall Ghost Girl is the second of the three ghosts that Coraline saves. Coraline referred to her as "pioneer girl" once while talking to Wybie. The Beldam put her real eyes in the pearl ring worn by the Other Miss Forcible.
The Tall Ghost Girl is, hence her name, a tall ghost with button eyes and a bluish-gray light. Until the end of the film, her face is stuck in an expression of exaggerated horror. She was presumably the first victim of the Beldam, having the most old-fashioned clothing. She is featured in a tattered dress and bonnet, and has a slight midwestern accent in the film. Also, when she and the other two ghosts are set free into the afterlife, her bonnet is missing and her dress is no longer is tattered. Her real name is a mystery since she doesn't remember it.
