Survivor: Kerguelen Islands

Twists
Hidden Immunity Idols: There will be a Hidden Immunity Idol hidden at each tribe's camp, including the merged tribe's camp. Hidden Immunity Idols must be played after the votes are cast, but before they are read and expire after the final five.

Mutiny: The castaways will be offered the chance to mutiny at some point in the pre-merge.

No Swap: Besides the Mutiny, Tribes will stay the same all throughout the pre-merge.
