Piggy as the Bigger Idea

One character that seems to be very odd and just wants to be liked is piggy. This character physically seems to be pretty fat and wears glasses. He seems like as a kid he did not have that many friends and seems to kinda be the loner. From the book it seems like he is really trying hard just to be loved by everyone but no matter how hard he tries he is always outcastes. I think this partly because of him growing up with no parents and living with his aunt where he can eat any amount of candy he want.
