You are a scientist who owns a laboratory, and after years of research you did it, you made vials every species of animal on the planet

You are walking through the lab, and enter the door, and behold you is 8.7 MILLION vials of every species, such as Mammals, birds, invertebrates, Mythical creatures and EVEN MORE! There is no limit to all the species you have, you can either drink it yourself, or give it to someone else, but be careful, it changes their mind and makes them act like that animal. The only way to turn them back is by giving them a human vial which turns them back to normal no matter what animal, so have fun and be careful!
