[Emperor's New Groove] What does Yzma normally use her llama transformation potion for?

Are there a lot of practical uses for turning people into llamas?

Animals are excellent for intelligence gathering.  Who pays attention to a bird, or a squirrel, or a beetle hanging out nearby? Given that people apparently retain their mental capacity when changed into an animal of any size, there are a lot of possibilities.  Once you know that it's possible you'll want to keep several different kinds on hand in case you need to grab a specific animal quickly.

Then, if you have the free time and inclination (or compulsion), you might as well see how many different animal extracts you can create.

Alternatively, Yzma was trying to create a potion of youth and animals were the best she could come up with.
