Fan Casting Julia Ghoul in "Ominous Opera" in IDEAS FOR CUPHEAD BOSS BATTLES

At an old opera theater that closed down and fell into disrepair, Cuphead, Mugman and Miss Chalice encounter Julia Ghoul, the ghost of a former opera star. Apparently, the reason the theater closed down was because at her last show, her held a high note that caused the props above her to shake and fall in her. She is rather vain and selfish. No one should stop her performance. Her weapons are grabbing props and whacking at you, and singing high notes and musical notes come out of her mouth right at you. Distractions are rats throwing bits of cheese at you and old living candles spewing flames. The final phase has either Julia possessing the stage or the entire building.
