80's cartoon question (dust off memories)

This was not a favorite cartoon of mine. I have no plans of tracking down any type of episode collection. I don't even have that fond of memories of it. But it bothers the hell out of me that I can't remember the name to maybe see the intro again.

Quick Description. It was on in the 80's. I think it aired right before or after Dungeons and Dragons. It started with a type of garage band playing and the entire thing was live action (filmed with real actors). Then, I think, someone removed a sheet from a tall mirror and they all get sucked in. The intro switches from Live Action to Animation. I think at one point they are all floating in a bubble and one of them actually acknowledges that they are in a cartoon.

If anyone remembers this I will be greatly appreciative. I've been racking my brain trying to remember.

Thanks.
