Named after the animal in the Chinese Zodiac, which was the symbol at the time of the game's release, "Year of the Dragon" is based on a nominal purple dragon Spyro as he travels to the "Forgotten Worlds" after 150 magical dragon eggs are stolen from the land of the dragons from an evil sorceress. People travel through thirty different worlds collecting gems and eggs. "Year of the Dragon" introduced new characters and minigames to the series, as well as improved graphics and music.
