The Attic, Basement and Beyond Shadow is the second-only female shadow, the other being the Medical Shadow. It is also the only double-headed Shadow creature. As Ned progresses through the Attic, Basement and Beyond Nightmare, the Attic, Basement and Beyond Shadow gradually transforms into a little girl named Sally, who carries a doll named Sandy Patty Cake, that she found on the trash. She calls the Attic, Basement and Beyond her secret treasure chest and makes Ned promise not to tell about it.
The Attic, Basement and Beyond Shadow is voiced by Jill Fischer.
The Attic, Basement and Beyond Shadow's personality can best be summed up as a sadistic child who loves to disturb those around her. She is occasionally very quiet, making her seem quite mysterious and giving off an eerieness akin to psychological horror. A lover of mind games, the ABB Shadow has set up her nightmare with several disturbing and strange tricks and traps that toy with Ned's mind, such as a dragon that tells twisted poems and stories. Her bizarre appearance perfectly reflects her bizarre and childish way of speaking, and she also longs for Ned to play with her, reflecting her childish nature.
