Scuzzy is Hexadecimal's cute little pet spy, a speedy wheeled...uh..something (think it's a cat) who can replay scenes it has recorded through a domed projector on the top of its head (the green part). Scuzzy is devious and slimy -- a nasty piece of work willing to rat out to anyone. Scuzzy can't talk but he can communicate as well as any sprite by replaying past recorded images to pull together patchwork sentences or mean-spirited comments. I wonder who fixed the glass on top of his head when Mike accidently broke it in "Nullzilla"
