Base model from B65ISP on Blend Swap, similar to Alligator by mraiser, but I cleaned up the topology for printing--no need for netfabb. I completely remodeled the inside of the mouth, the neck is not stretched, there are no intersecting polys (teeth, tongue, eyes, back), and there are no holes in the mesh--completely manifold. Slicing is much easier. Removed some of the texturing.
