A floating decoy system is provided for agitating the surface of a water body on which the device is deployed in a manner that is attractive to live game animals (e.g. live waterfowl). The system includes a frame, which is disposed partially above and partially below the surface of the water and suspended from a plurality of floating means. The device also includes an agitator assembly, which is slidably mounted to the frame above the surface of the water and produces ripples on the water surface and the sound of splashing water. The ripples and sound of splashing water are intended to simulate an active area where wild game are swimming, feeding, and interacting. Additionally, an airborne decoy may be mounted atop the frame to give the device added attractiveness to wild game. An alternative embodiment requires the removal of floating means and the anchoring of the frame to the bottom of the water body. The invention further includes a method for attracting live game animals to a target area by agitating the surface of a water body in a manner that simulates the appearance and sound of swimming, feeding, bathing, and commingling live game.
