This Mickey can be found in Disney Outfitters on Discovery Island! Look up over the door frame in the Constellation Room to find a classic Hidden Mickey made out of three stars on the far right hand side of constellation.
We're not sure if this one counts yet; my teen thought this one had to be by design! We had found several Hidden Mickeys elsewhere in the parks. I think we got a little crazy on the hunt!
Thanks! We enjoy HM's so much!
In DinoLand, U.S.A. at the photo posing spot at the rear of the Fossil Fun Games area, look in the smoke or clouds of the drawings on the poster boards; a three-circle image is on the front poster behind and below the rear red fin of the car.
