Matilda Mystical Mutations

Hy, my name is Matilda, from Mystical Mutations. Did you always want to be a little Birdy? Have the Keen senses of a Dog? Be able to lick your own Ass like a Cat? I think you get the point, I Can transmute you into any Animal you want. All I Need is a Sample of that Animal and Boom I will transform you. (The Sample will sadly be destroyed)
For each 10 Min. you want the Transformation to last, I require 10 GP. You can stay Transformed for Days if you want. But Early Termination of Transmutation does have a Fee of 100 GP. So be careful what you want to transform into.
