S1·E28 The Bride of Kuzco

After many attempts, Kuzco finally gets a real date with Malina. Then, after years of searching the Royal Matchmaker returns with a princess for Kuzco to marry. When Kuzco finds out that he can be emperor again if he marries her he agrees to marry her and blows off Malina, who doesn't take it well. After the princess rearranges the thrown room and forces Kuzco to take all these lessons, he decides he doesn't want to marry her. He then strikes up with a deal with Yzma, she’ll turn the princess into a frog, and then she gets to be empress for a day (to impress her visiting mom). However, Yzma has tricked Kuzco and she ends up empress for life. Then the princess turns back to a human negating the deal, however, Kuzco still has the ultimate decision, marry the princess, or go back to living with Pacha and go to school.
