Here is another picture of Scarface. People seem to take a liking to him on that previous post.
Here I tried something different. I strapped my mini-mag flashlight to the monopod with the camera mounted and worked it down into the prairie dog burrow. This take was the only one that worked fairly well. All the other holes had a bend just a foot or so in which I was unable to negotiate past with the monopod. You can see that in the first hole. Turn your sound down a bit as it may be irritating with the camera rubbing against the wall of the burrow.
