The Just So Stories generally have the theme of a particular animal being altered from an original form to its current form by the acts of human kind or some magical being. Whale has a tiny throat because he swallowed a mariner, who tied a raft inside to block the whale from swallowing other men. The Camel has a hump given to him by a djinn as punishment for the camel's refusing to work (the hump allows the camel to work longer between times of eating). And so on throughout the book. A fun collection of stories with something for everyone
