Its called "Treetop Treasure".
The Amazon is well know for its tropical trees, and at the top of one lays the Immunity Idol. But which one.. you have a choice of eight trees.

- If you pick the wrong tree, you loose and can't pick a tree again.
- Pick the tree with the Immunity Idol, you win immunity for your tribe.
- There may also be a few other things hidden up the trees..
