El mundo al revés ('The World Upside Down') is a children's play that includes live percussion, singing, and masks. In this allegorical play, the moon gives birth to a group of children whose well-intentioned actions make the world an ideal place to live. The moon also gives birth to the devil, who curses the world and changes everything for the worse. People get organized and help each other, and they finally defeat the devil and his dragon. Following the devil's death is a beautiful day in which a series of rights are honored and enjoyed: the right to land, health, education, work, housing, and other human rights.
