I don't know about the dimpling but I know of XYZ Reptiles. There is a reptile store a county over that sells their snakes. I think they are based here, probably in Miami like many of these in house breeders are. I have never seen them at the expos though. If I recall correctly, the snakes look fine at the store. But that pet store takes care of their animals, so who knows if they arrived that way.
