-THE MOJAVE DESERT-
The shuffling noises that one would hear in the heat of the Mojave are not what you'd expect to hear at the moment. The crunching of straw, as if something was shuffling along, made entirely of dried straw.
One would also not expect to see the creature shuffling and shambling along in the desert. Both because of how unfitting it is for the environment, and because of what exactly it is in the first place.
