Hey all. I'm trying to find a fic I read on Ao3. It was an animal transformation fic where Sam got hexed into snake form. It wasn't cute or fluffy at all, though. It was an angsty, creepy sort of fic where Sam found himself slowly losing time, memory, and even his personality -- becoming more and more snake and less and less Sam. It was mostly Sam POV, if I recall, and set at Bobby's?

Does anyone know where I can find it?
