Finally! Here's your picture of Munchie!
Here's why I couldn't find a picture of him...it's spelled Munchy, not Munchie. My mistake
Well, if you check out this link:

You can check him out. The website I got it from was for something called the Krofft Superstars Hour, or something like that. Anyway, they must've added the teeth when he joined the Barbara Mandrell Show. And in this photo, he's eating a surfboard. There's another photo from that site of the same thing only he hasn't taken a bite yet.
I don't think the arms moved on this puppet, they were stuffed (kind of like Big Bird's right wing) and the puppeteer used both hands to work the mouth (I'm assuming). And I'm guessing that the eyes were those typical Krofft eyes where a small black ball was glued behind a clear half-sphere, so it would roll around when the puppet moved.
So yeah. That's Munchy, or I guess they call him "Mr. Munchy" on the website. He freaked me out when I was a kid, but now when I look at him, I can't help but laugh because of that Munchy Blooper where he fell over backwards! I'll never forget that! LOL!!!
Oh yeah, I remember what came on after that blooper...it was a Wilkins Coffee commercial! I don't remember it word for word, but it went like this:
(Wilkins and Wontkins are sitting on a typical Muppet brick wall)
Wilkins: So, what do you think of Wilkins Coffee?
Wontkins: I think it's awful!
(The wall blows up right where Wontkins is. He crawls up out of the bricks and smoke, scared out of his wits)
Wontkins: Uhhhh....just kiddin' Mr. Wilkins!!!
I wish they'd bring out those old commercials on DVD!!!
