That night, the pirates raid the Stanley estate, and the Pirate King orders their execution. Mabel demands a "happy ending" – admitting for the first time that she believes this all to be a dream. Everyone – even the pirates – cheers their approval, leaving the Pirate King disappointed and shocked. Mabel then confronts her father, but the Major-General is steadfast that the marriage custom remains in effect. Mabel quickly pairs each of her older sisters with a pirate, and she also pairs the Pirate King to Ruth. With Mabel and Frederic now free to marry, the fantasy sequence ends in song and dance.
