S02E17 The Emperor's New School Spirit

Kuzco walks into a pep rally only to be let down by the realization that no one is interested in him; their excitement is all for the school mascot, Victor the Llama. In an effort to steal the spotlight, Kuzco plots to eliminate Victor. At the same time, Yzma is gearing up for her high school reunion but is hesitant about attending due to memories of the teasing she endured from her classmates.
