"I am not all that well versed in the more advanced types of mechanisms developed by the humanoids, however, I know enough to enable the alteration of their exterior forms into... more practical shapes. Project Samra was one such a test, while the outer form appeared to be made even partially out of fur and flesh, it was all entirely faux and required a bit more magically enhanced substances to get any sort of transformative reaction. In the end, I was rather pleased with her form. The Archmage will be pleased as well, I'm sure." Description stolen from  doctorsavato posting here: http://www.furaffinity.net/user/doctorsavato/
