The Pig is the 12th and final Zodiac sign – the exact reason is unclear, though there are several theories. According to popular Chinese myth, the Jade Emperor decreed that the order of the Zodiac was decided by the order in which the animals arrived to the party. The Pig, apparently, overslept, though other stories tell that a wolf destroyed his house, and he refused to set off until he had rebuilt it. In any case, by the time the Pig arrived, he could only take the last remaining spot.
