This season introduced the eponymous Island of the Idols, as Survivor alumni Sandra Diaz-Twine, winner of Survivor: Pearl Islands and Survivor: Heroes vs. Villains , and Rob Mariano, winner of Survivor: Redemption Island , returned to the game as mentors living on the Island of the Idols, though they did not compete for the million-dollar prize themselves. Instead, Diaz-Twine and Mariano periodically hosted a contestant each episode and gave them a lesson to assist them in the game. They also gave the contestant a chance to win an advantage, but if they failed, they lost their vote at their next Tribal Council.
