The Dragon Prince

The Dragon Prince is the son of the King of the Western Ocean. One day, playing with matches, he set the palace on fire. Magic pearls were destroyed and his father accused him of starting a revolution. He was hung up in the sky by the Jade Emperor, awaiting execution. Guan Yin arranges an acquittal and the Dragon Prince is turned into the White Horse, the beast that carries Tripitaka on the journey to the West.
