To make this skin, I had to combine these two skins in blockbench together and have some editing on this site, so credit to both of these:

This is a lamb skin with the traditional cape on it. I was going to add a mouth but that would require taking away the wool of the lower head and make it look more humanoid than it does in the source material, so I will let you decide if you do that through editing it yourself before downloading.
