Four monsters are chosen and they are blindfolded and sat in the middle of a circle that is formed by the rest of the players. In front of these monsters sits their treasure. They have bean bags for ammunition. One person is chosen to go and get the treasure. The monster can stop trespasser by hitting them with a bean bag. The players in the circle can help the monsters by telling them where the trespasser is. The winner is the first person to collect all the treasure from a monster. He then swaps places with the monster he got the treasure from.
