It is time for the annual Nut Festival and Kuzco wants no part of it, so he heads to the river. When Bucky bothers him, he throws a nut which ends up breaking a dam and washing away the festival. He blames it on the squirrels, so the villagers decide to gather up all the squirrels and ship them out of town. Yzma takes advantage of this and uses a pie to turn Kuzco (and accidentally Kronk) into a squirrel.
