What is piggy like in the middle of the novel?

Piggy is described as being shorter than Ralph and very fat. He wears a greasy winde-breaker and thick spectacles. Piggy suffers from Asthma and has thining hair which never seems to grow any longer. At the start of the book Piggy is clearly desperate to befriend Ralph and subjects the fair haired boy to a constant stream of inconseqential babble when Ralph makes it abundantly, if subtly, clear that he would sooner be alone. Piggy constantly refers to what adults would do and what adults would think. He is clearly uncomfortable being on an island where there are no adults. He is aware that he is physically vulnerable and he is also aware that Jack actively dislikes him.
