NEED GOODIES HELP!!!

I think this was the show, it aired on public television in the US back when I was in elementary school, in the opening credits I remember some of the main characters on the back of a dinosaur or loch ness monster that's about to bite them off it's back. I also recall two episodes, one where the characters melt the icecaps and it floods London, and one where they were trying to summon Satan, but they muck that up at the end as well. Is this the Goodies?

He asked us, "Be you angels?"
and we said, "NAY, we are but men," ROCK!
