She gets a little closer to take a curious look at it's mane before floating a small, glass collection jar over from somewhere.

"Will you allow me to take a small sample in exchange for the shoes then?" Trixie was always sure to ask plainly and reaffirm what the trade would be, because vague wording could cause trouble later.

((ooc: Is there anything she can learn about it from it's mane/hair? Like is it made of metal, fiber optics, it has magic, etc. I can always say that it's unidentifiable or whatever if you want though.))
