I've seen that mud somewhere before too, in a book, which one I don't rightly recall, either one of Mr. Bartlett's or in the Snakes of the United States and Canada.
My contribution, albeit not nearly anything as awesome as the mud, or the albino Gastrophyne
Jake and I cruised this guy up when he was down here just recently. Scarlet snake.
I have others I'll have to dig up out of my photobucket account.
