In 1874 Offenbach substantially expanded the piece, doubling the length of the score and turning the intimate opéra bouffon of 1858 into a four-act opéra féerie extravaganza, with substantial ballet sequences. This version opened at the Théâtre de la Gaîté on 7 February 1874 and broke box-office records for that theatre. During the first run of the revised version Offenbach expanded it even further, adding ballets illustrating the kingdom of Neptune in Act 3 and bringing the total number of scenes in the four acts to twenty-two.
