I think there is an optical illusion. It looks like there are two in the 4th picture!
I've always been a fan of soaking my lizards and snakes too. I don't think most people do that very often.
Another thing I like to do for all of them is make a humid hide box. I use a plastic box of the correct size for the animal and cut out a round hole just big enough for the lizard or snake. Then I use damp coco coir or coco chips inside. I always got perfect sheds this way.
