Club Mario (partially found live-action segments of "The Super Mario Bros. Super Show" animated series; 1990)
During the summer of 1990, Club Mario replaced the Mario Bros. live-action segments of The Super Mario Bros. Super Show.
This featured "extreme" Mario-obsessed teenagers Tommy Treehugger and Co M.C. (Chris Coombs and Michael Anthony Rawlins) goofing around, and in at least one episode, running around the DiC studios and harassing DiC executive producer Andy Heyward. Victoria Delany played Tommy's sister Tammy Treehugger. Rawlins also portrayed Co M.C.'s twin brother "Evil Eric". An additional added segment was a one-to-two-minute viewing of Spaced Out Theater, hosted by Princess Centauri, a green alien woman, which was edited from the TV series, Photon.
As of October 2016, at least 13 segments were found and posted onto Youtube. It is not sure if the rest of the segments are missing or if they were supposedly destroyed after airing, especially seeing how none of the segments, found or not, were reused for future releases of DiC's Super Mario cartoons.
It is not very likely to see more of those segments resurfacing, considering that Club Mario was very much disliked by its target audience which much preferred the original Mario Bros. skits with Captain Lou Albano - that still remain a nostalgia classic.
