From publisher's website (page 19 of catalogue):
Sitting Ducks Gallery TM Card Game is the new version of the popular Sitting Ducks Gallery game! The object is to maneuver your ducks down the row and avoid getting in the line of fire!
Get your ducks out of the water before feathers start flying, because cards can target, shoot or move the line in various ways! If your birds of a feather can stick together and keep from getting hit, you could be the last Sitting Duck in the lake!
