Hidden Immunity Idol

Peru
In the pre-merge game of Survivor Peru four idol halves were placed on each tribe's beach. In order to obtain a full Hidden Immunity Idol, one must find two halves. At merge the idol half twist disappeared. At merge there was also an idol with "special powers". These powers allowed the owner of this idol to play it after the votes were shown. This idol was revealed to exist at the second individual immunity challenge, where Angie stepped out of the challenge to obtain two clues for this idol.
