The Bride of Kuzco (S01E28)
After numerous attempts, Kuzco finally secures a date with Malina. However, the Royal Matchmaker reappears after a long absence, presenting Kuzco with a princess meant for marriage. Learning that marrying her would restore his status as emperor, Kuzco chooses to pursue this arrangement, leaving Malina heartbroken. The princess quickly makes changes in the throne room and insists on rigorous training for Kuzco, leading him to reconsider the engagement. He then strikes a deal with Yzma, asking her to transform the princess into a frog in exchange for a day as empress. But Yzma outsmarts him, claiming the title permanently. When the princess reverts to her human form, the deal is voided, leaving Kuzco to decide between marrying her or returning to Pacha and continuing his education.
