Corrected entry: Carts with wheels were not used in the Incan empire. Not only would they not work with all the steps carved into the mountainsides, llamas refuse to pull things behind them. They were used as pack animals.
Corrected entry: When we first see the poison, it's in a container that Yzma knockes over to kill the plant, and she gives the container to Kronk. How did it get into a little vial labled with a human skull-that-is-mistaken-for-a-llama if all Kronk had to do was pour the liquid from the container into a vial and from there into the emperor's drink?
Corrected entry: When Tipo (Pacha's son) wakes up after his bad dream, Pacha's wife comforts him and says that Pacha is fine and went to go see the emperor. However, the last time she saw Pacha, he said that he'll put their llama back. He never mentioned going back to the emperor. Therefore, there is no way for her to know that Pacha went back to see the emperor.
Corrected entry: The journey between Kuzco's palace and Pacha's village has to take at least an entire day (It's night when Kronk knocks Kuzco out, day while Pacha is traveling and dusk when he arrives back home), surely during that time Pacha would have stopped for even a brief rest so he should have noticed the large sack on the back of his wagon before he got all the way home.
Corrected entry: This is a 2 parter, 1. If potions don't have to be drunk but just touch the person then Kronk would have turned into a llama when he faked drinking the drink at Yzma's house, or when he used the mitt to mix the drinks again. 2. And the palace guards did not have to drink the potions that Pacha spilled when he knocked over the table in Yzma's lab. (00:15:00 - 01:04:50)
Corrected entry: When Pacha and Kuzco Llama go to look for the Human Potion, they open the owl cabinet and find the labels Lions, Tigers, and Bears. When Yzma knocks the cabinet, all the potions spill out, including the Lions, Tigers, and Bears. But Kuzco tried all the potions and never turned into a lion, tiger, or bear.
Corrected entry: Pacha gives Kusco his green thing to wear to the restaurant as a disguise, but later when Pacha leaves Kusco you see that Kusco still has his robe thing and eventually takes it off and throws it on the ground. Soon after you see Pacha wearing his green robe thing talking to the other Llamas.
Corrected entry: In the dinner scene, Kronk is handing out a drink to Kuzco on a platter. The one with the llama potion is farthest away from the other two (which are close together). But when Yzma tells her sidekick to give the emperor his drink (after Kronk saves the Spinach Puffs), all of them are evenly spaced.
