I'm not sure what makes this mouse so menacing. There's a significant possibility that it has something to do with his metallic purple suit or his random, off-putting hair sprig. I mean, I get it. Rodents shouldn't go full Elmer Fudd and be totally bald. They certainly need bangs at the very least. OH WAIT, THEY HAVE FUR.
Actually, the most concerning factor is the eyes. The dark, soulless eyes. Something mysterious drawing you in, easing you closer to certain doom.
Good luck with that, buddy. Good luck.
