The players try to win a dinner that includes salmon, chicken and shrimp in the “Return to Sender” Reward Challenge, which requires the castaways to throw a boomerang into a target. For Immunity, it’s a mental activity called “Don’t Fence Me In.” Ropes are attached to wooden posts and set up in rows of 10. The players link posts together using the ropes. The player who finishes off more squares wins Immunity. At Tribal Council, the eighth person is voted out of the game.
