While Simon is on the mountain, coming to terms with the beast, Piggy and Ralph are left alone on the beach, playing in the water. It's "the only thing to do," Piggy tells Ralph. While Piggy worries about getting his glasses wet and the impending storm clouds overhead, Ralph asks where the other boys are. Piggy points toward the grassy platform, the sight of Jack's party. All of the boys, aside from Simon, have gone to eat their fill of pig. All three of the boys will eventually join the party, where Piggy once again becomes the object of their derision. Simon, however, will not survive the night.
Everyone deserts Ralph and Piggy because Jack tempts them with food. The boys are tired of eating berries and they want meat. They join Jack's tribe because they want to have fun. They want to be wild and carefree.
