The Emperor's New GrooveGoofs
Errors in geography
When Kronk is pouring the drinks at dinner, there is no bottle on the counter, only the tray of goblets. Also, while he is pouring, look very carefully. He is not pouring into all of the goblets, he is only pouring into the first goblet three times. Furthermore, he is not heard or seen setting the bottle down before popping the cork off of the potion's vial.
Incorrectly regarded as goofs
The room where Kuzco looks at prospective brides has a peacock feather motif. Peacocks are Asian, however the "modernized" pseudo-Incan society depicted here does have commerce with the rest of the world, as shown in the sequel Kronk's New Groove (2005).
