Vaval is always on Ash Wednesday and the tradition was brought back by Marius from Le Select decades ago. The celebration still starts at Select. This tradition has many meanings and here I will only post one that I found:
Through the King of the Carnival, the population can publicly, once a year, express its opposition to the authorities without being punished for it. He helps regulate the relationship and the balance of power between the people and the public authorities. His repeated appearance and death are means to bring an end to political and social conflicts without any act of violence. "The politics revives annually under the sacrificial form of a liberating death."
