Duel eu jeu d'au is a game to be played in a bathtub or swimming pool, but it can also be played in a sink. The "board" is a round plastic ring with a net attached. The net is placed in the water and four red and yellow flowers are placed inside the floating ring. At "go", two players fill their animals (purple and green hippos) and sprinkle water over the opponent's flowers, trying to make them sink. The first player to make the other player's flowers sink wins.
