Lost Super Mario Bros. Super Show Pilot?

Usually animated series recycle clips from their first episodes for the intro. Brandy & Mr. Whiskers comes to mind, where roughly half of its intro is comprised of clips from the first episode, both segments; the rest comes from random early segments of the 1st season. However, the first eight seconds or so, as far as I know, is unique animation made for the intro and compared to the animation in the episodes it looks more fluid and I believe the waterfall is CGI, which is rarely ever used throughout the series, though I can't confirm that. AoStH is the only series I can think of that used an unaired pilot episode for, in this case, the outro, whereas the intro has unique animation meant for it. There's also Battletoads on reusing clips of the pilot episode for the intro, but that one doesn't count.

Super Show's intros, both main and cartoon, definitely have higher quality animation than the show itself, so the idea of it being taken from an unaired pilot seems plausible, however there are some shots on both clips where the animation clearly looks cheaper; this leads to two possibilities: either the pilot did happen and clips of it were reused for both intros and added new ones so that the intros look cohesive, or the animation was done solely for the intro to give a good first impression to audiences but it went overbudget and resorted on the actual animation studio that worked on the episodes to finish it up. Granted, I rarely saw Super Show's cartoon segments, myself, so I can't tell if there are any episodes which animation matches that of both intros.
