This game is a variant of blind man's buff. One player is blindfolded and spun around. The other players choose an animal (cow, duck, pig?) whose sound they imitate during the game. Before the game starts, they tell the blindfolded player which animals there will be. "IT" then chooses one animal they will "hunt", that is they has to catch the player who makes the correct sound
