In the Mike Fink Keelboat queue area, three pulleys hanging on the wall form Mickey.
As you descend down the ramp to the dock, look at the break room door and there to the right are three pulleys. They are formed in the shape of the three circles for Mickey's head. However they are not round in shape, they are noted as one by the Imagineers.

There is a hidden Mickey on the "Mike Fink" boat ride in Frontierland. In the loading area, look ahead at the boat house looking area. There are ropes and hooks etc. One of them forms a perfect Mickey tri-circle.

When you exit the raft after returning from Tom Sawyer's Island, you proceed along the dock to your right. After you get back on dry land, look back to the small shack on a neighboring dock. A fishing net is hanging on the back, containing three glass globe fishing floats arranged as our hero. You can see this one quite well from the park bench on the shore there.

Although when I went, the ears were a little tilted. Looks like somebody had been messing with this Hidden Mickey.
