If you do indeed know what a “Hidden Mickey” is, then you’re smiling right now and probably proud of yourself that you’ve found a few or more. A “Hidden Mickey” is a Mickey Mouse shape that Walt Disney Imagineers have strategically placed throughout the Disneyland Resort. (They’re actually in all the resorts.) It comes in many forms, from a complete Mickey Mouse profile to the outline of his head and ears. They come in all sizes and they’re fun to “hunt.”
This video shows some of the Hidden Mickeys found in Disneyland.
