Miley is a spooky ten-year-old girl who lives in a haunted house with her eight-year-old sister Monique. Miley always wears a black long-sleeved full-body hooded cloak, a pair of black gloves, a pair of black boots and a white skull mask that hides her face, while Monique always wears a black long-sleeved full-body hooded bodysuit with white skeleton bones on them, a pair of black rubber gloves with white bony hands on them, a pair of black shoes with white bony feet on them and a white skull mask that hides her face. Both of them live with eight bats and five spiders that can all speak like people do and are dressed up in spooky masked costumes like them.
