I was watching a TMS episode last night, and watching the theme, a longtime wondering that I've always had came back to me, and now that I have a whole forum to discuss it with, I thought that we should. In the opening of TMS, when the five monsters come out at the beginning, Sweetums is there. However, Sweetums looks entirely different in that opening than he ever did in any other appearances I know of. Originally I had thought that that was simply an original version of Sweetums, but once I got the TMS season 1 and The Frog Prince, I realized that it couldn't be. In all of those appearances, Sweetums has his original design. Yet at the beginning of season two (when the opening was filmed), Sweetums has a different design than he ever has had.
