 * The doll comes with a red, black and silver guitar case with white spider web patterns, a Memphis "Daddy O" Longlegs figurine, a real-life sized black brush, a black doll stand and a diary.
 * Operetta's stockphoto shows her with a purple brush, implying she comes with a purple doll stand. The doll has never been put on the market with those. Also, her stockphoto erroneously shows a set of bracelets that actually belong to Howleen Wolf's Campus Stroll outfit.
