(After Kronk accidentally breaks open the orb containing Kuzco's original life)
Malina: What's going on? Why am I holding you?
Kuzco: 'Cause I'm cuddly!
When Yzma wants to put "Yzmatopia" on top of the hill where Pacha lives, Kuzco mentions that he "almost did that same thing with "Kuzcotopia", but didn't go through with it". This is a reference to the first movie, and confirms the show takes place after the movie.
The episode title and skyline of the city are references to the movie Metropolis.
This episode is similar to the movie, It's A Wonderful Life.
