First, the footprint is barely larger at about 4.5 inches (The print goes from 1” to 5 1/2” in the picture) than my own. Second, I could make the same footprint by stepping in mud with a wetsuit boot on. Third, and the real give-away, is that the toes were made after the footprint and one at a time starting with the baby toe.
This is clear because you can see that the toe beside the big toe has smooshed mud into the print of the middle toe and then the big toe has been put in last and overlapped the second toe, smooshing mud a third of the way into it. I don’t know who the jokester is, but it’s probably a neighbour.
