This game can be played by many children. The children should be older than 3,5 years old. To
 play this game you need a big space. You need one mattress for every three children. One or
 two of the children will be the sharks. If four children are on one mattress the boat will sink and
 the child must try to get to another mattress with one or two children before the shark eats him
 or her. The object of the game is that the children keep moving from mattress to mattress
 looking for food. The mission of the shark is to eat the children as they go from mattress to
 mattress.
