Due to the hat originally belonging to Bobby, Nelson occasionally loses the hat on windy days, which, of course, means he's got to get it back.
This image depicts a scene mentioned in one of the chapters of my "On Our Own" audio story on Fur Affinity. Check it out bobbythornbody . Star makes a comment about how the hat might blow off Nelson's head any second, due to it being too big for him. Bobby remarks that it's happened in the past, prompting this image.
