I just watched the newest one. I don't know who played the characters, but they were pretty good. Animal was amazing. He sounded just like Frank! Dr. Teeth wasn't bad, but the characterization was pretty close, so I liked it. I just wish they could use him in more productions. I don't get it: Rowlf and Dr. Teeth worked pretty well for the videos, yet they haven't been used a lot in more major productions. Why is that? Are they afraid we might not like them, or do they find it easier to write for Pepe?
