Everyone begins the game as an octopus and stands on one side of the playing field.
One person is chosen to be a shark and they will stand in the middle of the playing field. Play begins when the shark calls out, “Octopus, Octopus, swim in my ocean!”
All players must run across the playing field trying to get to the other side without getting tagged by the shark. Anyone who is tagged must sit down where they are tagged. They now become the shark’s helpers.
When the shark calls out “Octopus, Octopus, swim in my ocean!” again, the players will try to run back to the other side. Anyone who runs within arms reach of the sitting players and gets tagged must sit down. The game continues until there is only one person left.
