I've been trying to figure out the name of a children's television show. I believe it was on Nickelodeon in the afternoons. All I really remember is the opening credits where I think two men were racing against the clock to unlock some mystery or other and by the end of the opening credits the one man is in a cave slowly turning into a reptile with scaly skin, etc. That's really all I can remember about it. Each episode may have been some mystery to solve or educational. I don't remember.
I have looked at lists of Nickelodeon TV shows from that era and haven't been successful yet.
