Bigfoot Or Lilliputian
It’s not something you see on a regular basis: a man wearing a mask while riding on the trunk of a car. There is no way for us to tell what kind of animal he is; he could be a Bigfoot, a Sasquatch, or even a Lilliputian for all we know.
Whoever it is has managed to hide very well so as not to give himself away, and it doesn’t look like we will run into him again in the near future. We can assume that he will take care of it, because when you do such hidden things, it means that you want to be anonymous.
