The growl by the roadside (Patreon)

"So, we totally just ignored this guy in grungy shorts asking for help, out by the forest road. We heard him getting super mad and cussing because we just drove by. But then, when we glanced back, he was starting to change! Like, thick fur was growing, and his fangs and jaw were getting bigger. The weirdest part? he man's facial expression began to change into one that seemed to be enjoying it."
