If you ride on Disneyland's Small World Holiday Edition, look for a small hidden Stitch in his Elvis attire. He is located on the front of a surfboard when you enter the Islands section of the ride.
Just as your boat comes around the corner you will get a straight on view of the surfboard and there he is sitting on top of a present on the front of the surfboard. He isn't more than 4 inches tall.
The surfboard rocks back and forth and is hidden at times so look carefully and quickly.
