Favorite Hidden Mickey...
My favorite one of all is in the best ride of all of Disney...
The Haunted Mansion, not the ones that cast members jokingly set up on the table to the far left with the 2 coffee plates and the Dinner plate, not the ones on the changing portrait prior to the stretching rooms, not even the fact that the two stretching rooms and the main parlor form a large mickey head that you stand in, but the one in the attic to the left of the Bride just prior to going down to the cemetery... I didnt see it so many times, but being a cast member, I had the priveledge of walking through the ride with the lights on more than a few times... i kept telling my fiance about it and had to take a flash picture to prove to her it is there because you cant really see it because your eyes do not adjust to the low light fast enough... (I know I know... sensitive ghosts) However to the left just before leaving the attic there are 3 frypans / skillets hanging in the attic with all the other clutter in the attic on the last wood post to the left of the doombuggy and they form a Mickey head in the pitch black of the ride...
Other than that maybe the actual carving of a mickey mouse head (not shaped like but an actual Mickey head) in a knothole at Disney's Wilderness lodge villas near the Iron Spike room he even has his eyes painted so you can make him out hidden in the wood..
The more I think the more I remember some pretty cool ones, but I cannot write a book here of all the ingenious ones WDI has put out there for you to find... the best ones are usually the ones that you just find for yourself...
