Panicked, Desperate, Thirsty as Hell

 was the second episode of.

Challenges
Reward Challenge: Stairways To The Stars The tribes would need to swim out to retrieve logs that are adrift at sea, with each tribe losing a member after each plank was recovered so that only one castaway would be left to retrieve the final log. The first tribe to build the stairway and use it to reach a platform would win reward. Reward: Tarp and blankets Additional Stipulation: The first placing tribe will have a choice between keeping their reward of tarp and blankets, or they would exchange it for a piece of flint, an extra cooking pot and a clue to the whereabouts of the first key to their tribe's rice crate. If the winning tribe picks the flint and pot, the two losing tribes would also get the same prize. Winner: Saboga (chose to give up tarps and blankets in exchange for flint; Chapera and Mogo Mogo would also obtain a flint, a pot and a clue)

Immunity Challenge: Float Your Boat Jeff Probst explained that there would be three boats at the bottom of the ocean floor. The first two tribes to swim down, free the boats of their heavy cargo, clear the water out, row to shore and carry the boat over the finish line would win Immunity.

Winners (according to finish): Chapera and Mogo Mogo

Final Words
"saboga"

- I talked to these people about two hours ago and everything was all set up to vote Ethan off and I can see Ethan voting against me but I can't see the other two people voting against me. If I was them, I'd stay clear of me. I have got a lot of friends. That's about all I've got to say.
