Duck and a Bubble

When I first saw this in camera, I thought it was a duck in a bubble. Once up on the screen, I could see that the bubble was behind the duck. I still like the pic though - it is something different.

The extra is a duck with no feet. Again, I didn't spot that until up on the screen. I wonder if it is a birth defect or an accident?  It would manage in the air and in the water, but how does it manage on the ground?  I am going to have to go back and observe it for a while.
