S2E49 Overachiever's Club

Kuzco finds himself in detention once more, but Mr. Moleguaco, suspecting he might actually like it, assigns him to the Overachiever's Club instead. Meanwhile, Yzma, under the impression that Kuzco is still stuck in detention, sneaks in to confront him. However, she gets trapped inside when Kronk fails to recognize her.
