Peachy welcomes the S5 into the immunity challenge, and then asks HeiDDi what happened to the charred-looking immunity necklace. HeiDDi giggles as she responds, "The right side got...a little scorched." The camera pans in to reveal that underneath the lettuce and carrots, the necklace has been strung together with lots of little skulls. On a more pleasant topic, Peachy is wearing a darker shade of blue today, which looks quite fetching with his haircut and new tan. Butch explains that they've rebuilt their fire hut and shelter, and Rob adds that although they lost a lot, it's "gut check" time.

Peachy narrates that, in today's challenge, the S5 will navigate through a ropes course containing five individual rope obstacles. In no particular order, they will make their way along a disk walk, maneuver a rope tunnel, use a rope swing, cross swing steps, and pass across a "V bridge," retrieving a colored feather after successfully completing each phase. All five individual obstacles pan outward from a net-surrounded center post, and the first person to complete the obstacles and get all five feathers to the center post wins immunity and a 1 in 4 shot of winning a million dollars.

Peachy removes the cooked necklace from HeiDDi, and begins the S5 on their challenge. The S5 head off in different directions: Rob to the disk walk; Matt to the tunnel; HeiDDi and her gravity-defying breasts to the V bridge; Jenna cursing her way through the swing steps; and Butch unsuccessfully attempting to use the rope swing. As we know from the earlier reward challenge, Butch is not so good at the rope swinging. He keeps swinging across and then failing to release the rope, which then drags him back to the starting point. Matthew, meanwhile, is an obstacle-course animal. We see various shots of the S5 working their way through different aspects of the course, with Jenna having the most difficulty with the swing steps as the others are returning to the center point with their first feathers. This challenge is very Fear Factor, complete with the requisite breast-cam. As Jenna finally returns to the center point with a feather, Peachy boredly announces, "Jenna with another feather. Way to make time." No matter how close the editors try to make this look -- and they don't even try that hard -- it's clearly Matthew's race. His final leg is the disk walk, which Jenna is already on. He charges up behind her as Peachy admiringly announces, "Bangin' his knees across those!" Matthew claims the last feather and heads toward the center point to Peachy's cry, "Bangin' those knees once again!" Maybe there's some sound we can't hear, but I don't know what that whole "bangin' knees" crap is all about. Peachy proclaims Matthew the victor as the others hobble around in the background; Peachy ties the immunity necklace around Matthew's neck, announcing, "Half of it burned off, but it's no less impactful or important." "Impactful," however, is less a word. Peachy's hand lingers on Matthew's back after he's secured the necklace and as he dismisses the tribe members back to camp to await the next Tribal Council.
