The Ultimate Shock

 is the season finale of Survivor: Palau.

Challenges
Day 37 Immunity Challenge: Tower Of Domination Survivors must race along a tire crawl, then navigate through a series of vertical escape hatches to reach the top of a three-story tower. Once at the top of the tower, the Survivors must use grappling hooks to retrieve keys that unlock a hatch covering a flag, which they must raise. The first two players to finish would race down a flying fox into the ocean and retrieve a combination lock box containing another flag. After figuring out the box's combination, the Survivors must retrieve the flag and raise it. The first to raise this final flag wins Immunity. Winner: Tom

Day 38 Immunity Challenge: Bob-Bob Buoy The Survivors must each grab onto a navigational buoy and hang on while the buoy swayed from side to side. The last player left hanging on would win Winner: Tom

Day 38
