In the beginning of the feast, Ralph is mocking the boys. He says they are pretending to act like a tribe. Ralph states that they should go to the feast to keep some type of order over the boys:
Piggy and Ralph go to the feast with the hopes that they will be able to keep some control over events. At the feast, the boys are laughing and eating the roasted pig. Jack sits like a king on a throne, his face painted like a savage, languidly issuing commands, and waited on by boys acting as his servants. After the large meal, Jack extends an invitation to all of Ralph’s followers to join his tribe. Most of them accept, despite Ralph’s attempts to dissuade them. As it starts to rain, Ralph asks Jack how he plans to weather the storm considering he has not built any shelters. In response, Jack orders his tribe to do its wild hunting dance.
Clearly, things get out of hand. Tragically, Ralph and Piggy get caught up in the frenzy of the dance and they particpate in the killing of Simon.
