Johnny is described as being, along with Percival, the smallest boy on the island, making him a littlun. He is said to be "well built, with fair hair and a natural belligerence". He throws sand at Percival along with Henry in chapter four. He is last mentioned in chapter six: "Johnny, yawning still, burst into noisy tears and was slapped by Bill till he choked on them." It is believed that he survived at the end of the book.
