We see a primitive-looking hut (as all huts tend to be -- except, that is, for Tribal Council huts), as the tribes arrive at the challenge. Peachy welcomes them and reclaims the idol from Christy. He announces that in a survival situation, awareness of their surroundings and the retention of that information are critical. The day's challenge will test the tribes' observational skills and ability to retain critical information. They will have two minutes to explore an "Amazonian Indian village," and Peachy will then ask them ten questions about it. The tribe with the most points after ten questions will win immunity. Jaburu has to sit someone out again, and Shawna agrees after Peachy makes a big fuss out of the fact that it can't be Christy.

Peachy dismisses the tribes to begin examining the two-tiered structure, and cautions them to check out the back area and upstairs, as well. The camera pans over pieces of wood; pigs and chickens; pineapples and plantains; and a bowlful of round small things. Alex explains to a tribemate that the stove is made of wood, while Joanna examines a life-size diorama of a grill with some manioc patties on it. Well, if the girls didn't know how to cook the manioc before, they do now. We also see a canoe containing a coil of rope and a close-up of a ladder. As Peachy calls them back for the quiz, he explains that they'll have to answer the questions independently and can't refer to each other for help.

Jeanne and Dave compete first, and Peachy snits that it should be an easy question if they've been aware. He asks, "What are the colors on the rattle that came with your treemail?" which leads one to wonder: why did the rattle come with the treemail, anyway? Dave answers "yellow," and Jeanne answers "red and yellow." The two other people in my viewing group both knew the answer to this one, which impressed me, but neither Dave nor Jeanne did. The rattle was actually red, yellow, and green, so neither tribe scores.

Deena and Rob are asked how many rungs were on the ladder leading upstairs. Deena wrongly answers "eight," but Rob gets it right with "six." So Tambaqui gets a point, leading the men to chant and yell.

Butch knows that there were nine piggies in the pen, while Christy guesses that there were six. Another point for the men! Two-zip, Tambaqui.

Alex and Jenna both know that there were nuts in the bowl, and I'm amazed that they both could tell those round small things were nuts, and maybe they weren't, because Peachy concludes, "Nuts'll work." The score is now 3-1, Tambaqui.
