Run It's a Shark and a Crow

OK so this is probably a dumb idea but I found it at a yard sale. I know I have seen the Great Blue Heron flying high in the sky. What if he looked down and saw a shark - would it scare him or invite him. Only time will tell. I figured if I had to float Styrofoam on the pond, Styrofoam with a picture might be more fun.
I have confirmed that the crows aren't concerned about the shark since they are still hanging around. Lucky for me the crows don't eat my big Goldfish (that I know of).
