Realistic Floating Crocodile

Scare the ducks that often visit your backyard pool and poop in it by having this realistic looking floating crocodile float on the pool. Most ducks will look at it as a potential threat and fly away, leaving your pool the way it is since it was last cleaned.

Or, if you are looking to have some fun, you can have it float in the nearby public pond to prank the passerby.
