When someone walks by that's when the fun starts! She can sense their presence. Scary? Maybe all this gruesome Halloween ghost girl wants is a hug? She lurks around the corner, watching, without eyes. Her hands begin to blink with wicked white light, then the sound of thunder crashes as her creepy, ghostly voice fills the air. Halloween yard decorations, those trick-or-treaters will think twice before double dipping in your candy bowl.
