Does anyone remember Cro?

So there was an education show back in 1993/1994 called Cro. The show revolved around a Mammoth called Phil being frozen in time until he is awakened in the 90s by a Latina scientist called Dr. Cecilia (or Dr. C) and a black kid called Mike. Phil would run into antics that he would relate to stories that happened during the prehistoric era that revolved a young Cro-Magnon boy called Cro and his rather simple-minded family of neanderthals. The show's purpose was to teach physics concepts to children. The show, as far as I know, was not officially released on DVD, but on youtube over the past 5 years there have been several episodes showing up in decent quality. The show was supposed to have 20 episodes total. Of these, 12 of them are available in full and in English, with the rest being available in various other languages... except for one single episode. Laugh, Mammoth Laugh is the one episode that appears to just be completely missing. Which is a pity since that one was one of my favorite episodes.

Does anyone have any information on it or on home releases of the show? It occupies a peculiar spot in my mind in that it should be nostaglic, but at the same time when I try to watch it I get the feeling that I just saw it last week or something. I did have one or two episodes recorded as a kid and I watched a million times over, and those episodes just so happen to be the first ones I saw on youtube, which might have contributed to that.
