Great Escape Run
"Each person must dig ladder rungs out of the sand in order to build a ladder with. The first person to build their ladder and climb to the top would win immunity at their Tribal Council. The winner would award individual immunity to one person from the rival tribe. Also, they would stay at the other tribe's camp to gather enough information that would help them decide which member of that tribe would receive immunity at their Tribal Council." ~ @SurvivorWiki
