Okay, but did you guys heard about original Disney's concept for Emperor's New Groove? It was called Kingdom of the Sun and it was about "selfish emperor who finds a peasant who looks just like him; the emperor swaps places with the peasant for fun, much as in author Mark Twain's archetypal novel The Prince and the Pauper. However, the evil witch Yzma has plans to summon the evil god Supai and capture the sun so that she may retain her youth forever (the sun gives her wrinkles, so she surmises that living in a world of darkness would prevent her from wrinkling). Discovering the switch between the prince and the peasant, Yzma turns the real emperor into a llama and threatens to reveal the pauper's identity unless he obeys her. The emperor-llama learns humility in his new form, and even comes to love a girl llama-herder. Together, the girl and the llama set out to undo the witch's plans."

I think, after some changes, it would make good storyline for Once.
