It's Halloween night and it's up to Scary Godmother to show one little girl just how much fun spooky can be! Meet Hannah Marie, who, with the help of Scary Godmother, stands up to her mean-spirited cousin Jimmy and her fear of monsters on her first Halloween adventure with the big kids. Later, Hannah joins forces with Orson, the vampire boy, to unravel a mystery near and dear to their hearts. Some of Scary Godmother's closest (and most frightful) pals get in on the fun too, including Bugaboo, the Boozle, and Skully Pettibone.
