In this chapter there is a description of a pig-hunt which ends in screaming and skipping around? What is said about that celebration

The hunters go into a frenzy once more, repeatedly chanting "kill the pig." Caught up in the momentum of their chanting and dancing, they jab at Robert with their spears, at first in jest, and then with more dangerous intent. Frightened and hurt, Robert drags himself away from the crowd, now aware that they are carried away with their game. Roger and Jack talk about the chanting, and Jack says that someone should dress up as a pig and pretend to knock him over. When Robert says that Jack should get a real pig that he can actually kill, Jack replies that they could just use a littlun. This re-enactment further blurs the lines between hunting and murder. It is rather disturbing that Jack's quip about hunting littluns was not altogether a joke.
