From the publisher: "Here is a crazy mixed-up matching memory game. Use the sneaker to step on a card - the suction-cup heel will pick it up! If the card you step on matches a card in your hand you get to keep the match. Players compete to collect the most, all the while trying to avoid the worst thing you can step in - dog poop! Contents: 21 Step-In cards, 28 Step-In squares, sneaker with built-in suction cup, game rules."
