As per Chinese Zodiac legends and mythology once Jade Emperor invited animals to participate in a race. The prize was that the first 12 animals to cross the river would appear on the Chinese Zodiac calendar in the order in which they completed the race.

The Cat and Rat were the worst swimmers in the animal kingdom. Although a poor swimmers, they both were intelligent. Chinese Zodiac legends and mythology explains that the rat used his brain rather than his brawn. Cat and Rat decided that the best and fastest way to cross the river was to ride on the back of the mightiest swimmer - the Ox. In midway Rat pushed Cat into the water. Just before the Ox reached the shore, the rat jumped off and crossed the finish line putting it in first place.

The Ox came second and occupied second position in the listed on the Chinese Zodiac. The tiger came in third, followed by the rabbit that jumped his way and arrived with a thumping sound. Fifth came the dragon. A snake hid in the hoof of the horse. Hidden on the Horse's hoof the Snake suddenly appeared and gave the Horse a fright, thus making it fall back and giving the Snake the 6th spot. Horse came next and got seventh place.

The sheep, monkey and rooster helped one another to cross the river and have earned their spots on the calendar. The dog decided to bath first then to get listed and that is why it came in eleventh. The pig feasted and rested half-way through the race, but made to last twelfth position. The Cat finished in at 13th place and could not find any position in the zodiac
