What makes it worse? It was her own father, which adds a whole new level of tragedy to the situation. What she didn't realize was that her victim was suffering from PTSD, and shot her out of fear in self-defense. It heavily implies that Spooky became a ghost when she tried to scare someone with an obscuring costume and fireworks. One of the endings reveals that she really is a ghost, and her entire reason for sending people into the labyrinth is to raise up an army of ghosts so living people stop calling her cute. It's not clear whether she used the gun on someone or if she finally managed to scare someone and got shot for her trouble, as one of the trailers show that even her ghostly appearance might be a facade.

Her backstory reveals that on one Halloween, after not being able to scare anyone with her costume, she does something that involves firing a gun. That, mixed the rather adorable outfits she wears, can make her seem adorable. She stutters, coughs, and acts ridiculously awkward while talking with the player. Adorkable: Spooky manages to be this despite her Jerkass nature.
