Recurring Survivor Challenge
Description: A recurring water challenge
Appearances: Caramoan

Cell Block Sea, (also known as Phish Farm and Serpent Turf) is a recurring challenge on Survivor.


Contestants must race out into the water and swim over to their respective tribe's bamboo cage. Once the entire tribe has arrived, each person must climb up and over the cage wall into the water. They will then retrieve a chest and bring it back to shore, where a final task would occur. The first tribe(s) to finish this final task would win.


The challenge debuted in Survivor: Caramoan, where the final stage involved moving the chest along a track and onto a platform using grappling hooks. The Bikal tribe narrowly defeated the Gota tribe to win immunity for the second time in a row. Bikal also won reward of two chairs, blankets, and a tarp

In Survivor: Cagayan, the Luzon tribe took a large lead over Aparri and Solana heading to the puzzle stage, but J'Tia cost them a taste of victory when she failed to complete the puzzle. Sarah managed to finish first for Aparri, and LJ finished second for Solana, sending Luzon to Tribal Council again.

This challenge reappeared in Survivor: Game Changers, where the castaways had to drag a 400-pound snake out of the cell and onto shore. Three remaining castaways from each tribe had to retrieve numbered tiles from the snake, after which a code could be solved, unlocking rings with which one castaway had to toss onto eight targets which spelt "IMMUNITY". Nuku had an early lead with their strategy of involving every single castaway, and Mana fell behind when Jeff struggled physically with the weight of the snake. Mana was set back by multiple trip ups on the balance beam, but they ultimately caught up with Nuku at the ring-toss stage. Even though J.T. was 2 targets from winning, Malcolm caught up. In the end, however, Nuku won immunity when J.T. narrowly edged Malcolm out.
