From TheGamer: “Seagulls are a menace to society. Have you ever seen a seagull swallow a hot dog whole? Well if you havent, you have not yet truly experience fear. If they can do that to a hot dog, then a larger seagull could easily swallow a man. Or, failing that, a child. As such, I can only ever encourage the act of thinning the seagull ranks, especially the large mutant ones. And in Red Dead Online, I wont be the only person telling you that you should be hunting them down.”
