From Survivor 23, South Pacific is the Savaii Jack and Jill treemail clue from Episode 7, this is the challenge/immunity where Cochran got the Savaii members hooked up incorrectly and it cost them the immunity. Savaii didn't win, Upolu won and got to injoy the screening of the Jack and Jill movie.
The challenge is described:
The tribes would split off in pairs of castaways. One pair would act as callers to the two other pairs as they navigate blindfolded and hooked to a rope through an obstacle course to collect four bags of masks. One pair of castaways would then use only their sense of touch with no help from the rest of the tribe to match the masks into pairs. The first pair to properly match all eight masks would win for their tribe.
This clue was purchased directly from Ozzy who appeared in the season.
