There's no such thing as 100% cinnamon. Does he mean a normal ball with cinnamon parents? I've heard of crazy people doing that with pastels.
Or is it a cinnamon het pied? That would be cheap then.
Most Het pieds will have a pattern on their bellies that we call "train tracks". The belly should be clean white with black side border that look like train tracks.
Can you ask him for photos of the snakes and their bellies(closer to their tail end)?
post them here when he does
