Dinosaur Jack's Sunglass Shack: Behind the cash register inside the Sunglass Shack, is a wall covered with assorted knick-knacks (reflectors, marbles, buttons, etc.). Hidden amongst all the clutter, peeking out from behind a hub cap, is Mickey's face.
Note: Dinosaur Jack was removed to make room for Paradise Pier's World of Color viewing area and The Little Mermaid dark ride.
