The Emperor's New School - Season 2 - Eps 33: The Good, the Bad and the Kronk
When Yzma gives Kronk the assignment of disintegrating Kuzco, Kronk consults his shoulder angel and devil. However, the two of them get into another fight and Kronk tells them to go away. With those two gone, Kronk can no longer make decisions. Yzma then captures his shoulder angel in a cage, and gives the shoulder devil back to Kronk. This causes Kronk to agree with everything the devil says, which causes him to try and disintegrate Kuzco.

It's about Kuzco, a self-centered and spoiled teen who must survive the trials of Incan public school and pass all of his classes so that he can officially become Emperor. His friend Malina keeps his attitude in check, while the evil Yzma (cleverly disguised as Principal Amzy) and her dim-witted sidekick Kronk are out to make sure Kuzco fails.
