Chilly Willy
Apparently there were several versions of Chilly, at least several variations. This image depicts a rather older model, probably shorts from movie theaters. We don't remember a whole lot about him, except that he was cute.
Speaking of that, now that we think about it, there aren't many cartoon characters who were cute like these guys. There's a sappyness to the revival of Care Bears and the like, but nothing like the adorableness of a Chilly or a Jerry or a Bugs.
