Cell Block Sea

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

Rules
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.

History
The challenge debuted in, 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.

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