Just went on a posting binge. TMAC almost made it off my feed, which can never be allowed to happen.
Anyway, I seem to vaguely remember Dynomutt. Like so many classic H-B cartoons, it was part of the endless rotation on Cartoon Network in the 1990s. Probably not very often, though, since I don't seem to remember anything about it.
That's the thing about CN--some cartoons never seemed to disappear. Others would come on once and then you'd never see them again. I remember this one that I thought was so cool, called Turbo Teen. It features a kid who can turn into a car--yes, you read that right. I swear, they played like two episodes of it one morning and it never appeared again. I watched intently thereafter, hoping the mythical Turbo Teen would come back. I had decided right then and there that it was my favorite cartoon ever. In retrospect, the idea is so ridiculous that I doubt it would hold my attention if I watched it today. However, I'd love to find it somewhere (I'ma hit up YouTube soon) if only to find the episode that contains the one line from it that I remember to this day: the kid shouting "I'm...Turbo Teen!"
