A wereanimal is a character, usually human or humanoid, that can transform into an animal, be it by will or caused by a curse.
Person 1: If you were a wereanimal, what animal would you transform into? I would be a weredog because I would get a lot of headpats and lots of free food.
Person 2: I think.. I would be a wereeagle! Imagine how cool it would be to transform into a flying creature and be able to fly and see a lot of things from a long distance!
Person 1: Oh.. Good choice!
