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!
Inside Backlot Express Restaurant, an upside-down Hidden Mickey is formed of a small trampoline and two rolled blankets below it. Find this image on top of a locker along a wall on the far left of the seating room to the left of the food order area.
