The boys on the island vary, of course, in numbers, according as they get killed and so on; and when they seem to be growing up, which is against the rules, Peter thins them out; but at this time there were six of them, counting the twins as two... They are forbidden by Peter to look in the least like him, and they wear the skins of the bears slain by themselves, in which they are so round and furry that when they fall they roll. They have therefore become very sure-footed.
Peter Pan, by JM Barrie
