Carved Humans Into Lambs?

We watched part of this in my Aesthetics of Cinema class, and when my teacher was answering questions he mentioned the barbarian being able to cut a person into the shape of a lamb. Watching this film for myself, I saw the lamb, but there were no big hints that it was a person. Do we just assume this cause he had people to work with, and there were obviously no lambs around. Or did they mention that somewhere and I missed it?
