They did for 1 sec in the Holiday Tag for Celebrate The Magic/Magic, Memories And You.thanks to @brb1006 for sharing that video. I thoroughly enjoyed it. '97 was about the time we started going to WDW. I don't think we got there in time for the "castle cake". Yeah, it was a commercial. But, it mentions a lot of attractions and live stuff that doesn't exist anymore. Would love to know how they did the castle -- was that fiberglass or some other material? Does it still exist somewhere?
I could totally see a projection show that made the castle look like that.
