Haunted Mansion (Nightmare Before Christmas)
Get on the ride. In the last room - the big one - towards the end (where you go under a bridge), but not quite at the end, there is a dog-reindeer-skeleton-thing holding a plate with cups of, we assume, cocoa on it. Three of the four cups are in a Mickey shape.
It's pretty high - about 10 feet above the car.
Cool site for the day:
