The Emperor's New Groove (2000)

Plot hole: When Kuzco and Yzma make a dive for the potion bottle, Yzma is turned into a cat simply by landing on the potion bottle. This suggests that a person only needs to touch the potion in order to be affected. However, when Kronk and Yzma are serving Kuzco dinner and are trying to avoid poisoning themselves, Kronk pours his potion drink on himself and is not affected.

Sussudio

Yzma: ...And he'll be dead before dessert.
Kronk: Which is a real shame, because it's gonna be delicious.

Trivia: When Kronk tells Yzma that he mixed the llama potion into the three cups, she tosses her drink into the cactus on her left. While Kuzco is transforming and the shot switches back to Yzma, you can see that the cactus is now llama-shaped.

Question: All of the vials that Yzma has are labeled, but how? They can't be inside the vale because they would be wet and Yzma couldn't have flipped the label up like she did in a scene, yet...there is nothing attaching the label to the vial. how is it attached?
