You've done it all before
Capitalize on past mistakes
Comfort awaits behind the door
And at least it was a short one. Paschal plays with his pants while hearing the clue, and then tells us in a voice-over that the clue says they'll do stuff they've done before, "whatever that means." He then hopefully tells the others, "It may not have anything to do with stilts!" Kathy quickly shoots him down, "Oh, yes it does!" He responds, "If it does, I'm out," and then explains in the confessional that he's never been able to figure out how to use the stilts, and that he'll just wait and see at the challenge. He concludes, "When Jeff tells us, that's when I'll know," and also that when Jeff builds it, that's when he'll come.
The challenge music plays as we see palm trees, colored trunks, the sand-filled towers from the slingshot challenge, and an angry-looking, exploited tiki. Peachy -- in a white cowboy hat and white shirt -- tells the S5 that in the thirty-four days they've been in the Marquesas, they've done and experienced many things, and he hopes they have few regrets. Vecepia looks incredibly unamused as Peachy continues that he knows there must be at least a challenge or two they would like to do over again. He reveals that today's reward challenge will consist of elements from six previous contests.
In the first part of the challenge, they will each have a "color-coded tiki that's been chopped into eight pieces." The S5 have to collect all the pieces which have been scattered throughout the jungle, and then correctly assemble their individual tiki. This is accompanied by a shot of the tikis magically assembling themselves.
In the second part of the challenge, the S5 are directed to find a pile of coconuts and break them open until a bamboo shoot overflows with milk.
They will then continue through the jungle until they reach stilts hanging in the air and tied to a log. They are instructed to undo the knots and release the stilts before progressing to the "stilt-walking portion of the challenge": a ten-foot section the S5 will need to cross before moving on. And I think this must be a two-parter: the untying of the knots, and the stilt-walking.
Next, the S5 will come to another pile of coconuts, one of which will contain a key. They will use the key to unlock a spray-painted trunk and then retrieve the slingshot inside.
In the last part of the challenge, the S5 will attempt to break one of their tiles causing sand falls on their tiki. And that's the win.
