This skull is pretty high poly; blender tells me it has 31,000 tris, so be warned. And it doesn't use rigid groups, so there's no guarantee that it won't behave strangely when morphing. Which you won't see unless you use my xray skin, since it doesn't use delete groups. It's pretty basic, but still fun. Usually my stuff is CC0, but I'm setting it to CC-BY because the original obj was from bodyparts3d. I just converted it to quads.
