Answer: This hidden Mickey was found at Seaworld, Orlando. It was in a relatively new shop, so I wonder if this was the work of some ex-imagineer poking a little fun at his old employer.
Since we live just a few short miles from Seaworld we decided to visit yesterday. Saw Shamu, some fun loving dolphins, and stingrays the size of a coffee table (had no idea they got that big). Can’t wait to get back. I could sit and watch dolphins and killer whales all day.
