Recently I discovered that treehouse of horror 3 had an unaired version that apparently was colored weird and didn't do well with test audiences, necessitating the writing team to come up with what they referred to as a "complete overhaul"

Besides this I can't find any new information on it, but I can't help but speculate as to how different the episode actually was. Was it the same episode just animated and written differently? does it contain different stories and wraparounds? somehow I am endlessly intrigued by the idea that one of the best treehouse episodes in the series has a potentially different version floating around somewhere unless it was destroyed.

anybody else know anything about this besides the very limited information I gathered? Google yields no leads.
