"One tribe member crams into a tiny barrel. Then, other tribe mates, who are attached at the waist, will roll the barrel up and into a special barrel-shaped cradle. The barrel dweller will then hop out, climb onto the barrel, and untie a bag of balls and then hop back into their barrel. The rollers will back the barrel out of the cradle, proceed to the next stand and continue the ball-retrieving process. There are four cradles in all and they are arranged in a zig-zag pattern along the course. Once all four bags have been retrieved, the barrel will be rolled into a final cradle and the inhabitant will burst forth to present the rest of the tribe with his or her bounty. The four remaining players will then roll the balls up a skeeball structure. The first tribe to land six balls in place wins immunity." ~ @SurvivorWiki
