Lord of the Flies- William Golding. Piggy's symbolism goes beyond that of his name. What other aspects of symbolism are linked to him?

Piggy is automatically disadvantaged the first time we see him; he is described as "the fat boy" who disturbs the undergrowth. When compared to the "fair boy," he seems the less fortunate of the two; Ralph already seems like an extension of the island, but Piggy keeps getting caught up in the creepers. While he's stumbling around, Ralph is walking about gracefully. Piggy acts very franticly, asking questions to Ralph,, while Ralph is answering calmly …

…smarter, Ralph can come up with plans. Ralph is more at one with the island: "The fair boy stopped and jerked his stockings with an automatic gesture that made the jungle seem for a moment like the Home Counties." On the other hand, Piggy tramps around the undergrowth loudly: "The undergrowth at the side of the scar was shaken and a multitude of raindrops fell pattering." He doesn't fit in any where, including the island.
