What kind of dance and chant do the boys do in lotf chapter 4?

In Chapter 4 of "Lord of the Flies," the boys perform a dance and chant as they reenact the hunt. The dance takes on a primal and frenzied quality as they mimic the movements of a boar and work themselves into a trance-like state. The chant serves to heighten the group's collective energy and build a sense of unity among them.
