The muppet babies are playing pirate ballet. Over the course of his long career Petipa presented four revivals of Le Corsaire, each time adding a substantial number of new performers, variations and incidental dances. His first revival was staged especially for the muppet babies, the Prima Ballerina piggy, with the Premier danseur kermitas Conrad. The production premiered on 5 February 24 January 1863, and included a score supplemented and revised by the composer fozzie For this revival, Petipa also extracted a pas de deux, the Pas d'esclave, from rowlf score to piggy's ballet.
They both are spinning around.
