Spooky is the titular deuteragonist, but also the main antagonist of Spooky's Jump Scare Mansion. She is the ghost of a girl who appears to possess a huge sum of power and governs the mansion of which the game takes place in. She appears to impact the events that have happened and will happen in the mansion. Her true nature is only revealed in the end of Spooky's Dollhouse.Spooky is a small, floating ghost, with light blue skin, black, oval-shaped eyes, and long, dark blue hair. She has rather simple, rounded features. In the base game, she wears a tattered, sleeveless, baby blue dress. Spooky can also be seen in several mini-games as sprites with very little change to her overall appearance, though she may be seen brandishing an oversized Bowie knife. In Karamari Hospital, she looks the same during the first playthrough. However, upon replaying in New Game +, she now dons a pink nurse's gown with a white nurse's cap, stylistically reminiscent of the nurses' uniforms popular in the 1950s. As a human, Spooky had the same simplistic, rounded facial features, and long blue hair. However, instead of the long, tattered blue dress, she wore a knee-length white dress, with little white shoes and pink socks.When still alive, Spooky was an insecure and misunderstood girl who was ridiculed for her cute appearance, which stemmed her determination to be able to scare anyone. Sadly, it was what led to her untimely and violent demise, as when tried to pulling pranks from someone with fireworks and her Red Death Costume, the man panicked so bad out of fear that he shot her to death. The violent death resulting in her return as a vengeful, sadistic, and manipulative ghost that Spooky unfortunately became. Her sadistic and indifferent to other people's wellbeing, which is made apparent as one of the Generic Lab assistants stated that Spooky gave cold shoulder when one of the monsters escaped.
