The Emperor's New Groove

Kuzco is a self-centered emperor who summons Pacha from a village and tells him that his home will be destroyed to make room for Kuzco's new summer home. Kuzco's advisor, Yzma, tries to poison Kuzco and accidentally turns him into a llama, who accidentally ends up in Pacha's village. Pacha offers to help Kuzco if he doesn't destroy his house, and so they form an unlikely partnership.
