The Yzma That Stole Kuzcoween is an episode from The Emperor's New School. Jealous Yzma can't stand Kuzco is the star of the popular Kuzcoween festival, so she decides to ruin it, enlisting Kronk by promising a star to replace the decorations with spookier ones, hoping to turn it into Yzmaween. When told he's too old for trick or treat, Kuzco decides to give the festival a trendy face-lift, and Yzma's work makes it happen without him lifting a finger.
