What is the best part in the movie lord of the flies?

Ralph says "Like icing, on a pink cake." In reference to seeing white sea birds nesting on a pink block of rock, which was 'sitting out in the lagoon.' This occured when Ralph went on an expedition to climb the mountain with Jack and Simon in chapter 1: The Sound of the Shell. The reference is near the bottom of page 27 in my edition of the book.
