The castaways scale new heights to earn a spot in the final four. Meanwhile, friends become enemies when one player overhears plans for her eviction; and Tony devises a strategy to use his special immunity idol.
The entire tribe goes on a wild hunt for hidden immunity idols. For a steak-dinner reward, the castaways divide into two teams to solve a puzzle. Later, for immunity, the players stand on their toes while pressing a block to a beam with their head.
The castaways drop their buffs and form two new tribes. The new teams play for a reward that includes coffee and donuts by dragging a person from the opposing tribe across a finish line. For immunity, the players carry a heavy log through a maze.
One tribe considers throwing the immunity challenge in order to get rid of its strongest member. For immunity, the tribes must retrieve five balls underwater and then toss them into a basket. The reward-challenge winners get chicken and eggs.
