She went to a store we have in downtown Austin called Oddities. She bought some ducklings...dead ducklings.
She named them Loki and Thor. She is going to make helmets for them.

How old is she, Helmets may be a good way to go, and unusual as some people look for the different and unexpected.
Actually the interest in taxidermy go back hundreds of years. It has become an art and very profitable business.
Any of you deer hunters out there had to pay to get a deer head mounted for display in your home ???? Anyone know the cost of having just a fish preserved from big mouth Bass to Sword fish ???
Teddy Roosevelt became an expert on taxidermy in his youth and so was ---As I heard, George Washington----
The interest in taxidermy may lead your daughter into a medical field, art, or the field of Veterinarians.
So your daughter may if young loose interest in dead animals, this may be just a one time thing for her.
Don't panic here, for the youths interests come and go, some may be just a whimsy as putting hats on dead ducks.
