"He wants to know what you"re going to do about the snake thing." This is the start of a creature created by the fear and the inner feelings of the boys in William Golding's The Lord of the Flies. The "Beastie comes in three different forms, changing as the society further disintegrates. One represents fear, one represents disorder, and one represents the destruction of their society.
The beast first enters Golding's story when a "little"un"" is pushed forward by his peers. The boy is such a wreck that Piggy is his voice. "Piggy knelt by him, once hand on the great shell, listening and interpreting to the assembly." The boy tells Ralph about his encounter with the creature he dubs the "beastie." The "beastie" is first described as a snake-like creature. This brings up an inner fear of the boys that starts a long process which tears apart the social structure the boys have created. The beast speeds the process in which Jack goes insane for his lust for blood. It makes Ralph go through an inner war in which he is fighting a deep fear of the beast and his need to be an upstanding leader. These two processes are a wedge in a crack between the two powers on the island: Jack and Ralph. It also induces nightmares from the little"un's and some of the big"un's too. The nightmares cause the eventual devolution of the society.
The second form of the beast is a mysterious man-like being, which Sam and Eric are "chased" by. "Then as though they had but one terrified mind between them they scrambled away over the rocks and fled." It is really a dead pilot who jumped out of a destroyed airplane with a parachute, but the night dark and the wind make the boys think that it is the beastie.
The third form of the beast is the Lord of the Flies. The Lord of the Flies is the bloody pig's head that Jack impales on a spear in the forest clearing as an offering to the beast. Unfortunately, Simon is near the clearing and witnesses the whole gruesome incident.
