"The Lost Kids" is the first segment of the seventh episode of The Emperor's New School.
Kuzco babysits Pacha's kids while Pacha and Chicha go to the "Cure All Spa & Hot Springs" for their anniversary, but the kids forgot to give them their present, so they leave without telling Kuzco, and now he has to bring them back. This is made harder when Yzma transforms the children into monkeys.
