Oh, good. Time for my least favorite thing. Treemail. The lamest thing ever. This episode's treemail tells the boys that they'll have to work together as a team, and talks about being in a cage. And the quality of the rhymes is just about as good as always, meaning "not as good as my four-year-old nephew could do." And that's assuming he kept one eye on Rescue Heroes the whole time. Christy talks about how excited she is for the challenge, because she thinks the women are going to do well. The change in their morale really is just remarkable. They prepare for the challenge by strapping on their machetes (in the case of Deena and Joanna) and brushing their hair (in the case of -- you guessed it -- Heidi and Jenna).

Back at Tam Beta Chi, however, Rob is preparing for the challenge by shaking the Magic 8-Ball to ask whether Heidi will notice him. The ball says, "Yes, definitely," because the internal icosahedron doesn't have a side labeled "Yes, if by 'notice' you mean 'pity.'" Jaburu marches resolutely through the woods to pounding drums, and then back at Tambaqui, Roger asks the truly creepy question, "Will Jenna give the old man here the look?" Alex enthusiastically says, "All right!" so as not to cry or burst out laughing. Magic 8-Ball: "Outlook good." Alex: "Bow-chicka-bow-bow!" Wow, he even does situation-appropriate porn soundtracks. I may be about to renounce all previous imaginary boyfriends. The women are seen approaching the immunity challenge by boat, and then we're back to the boys and the 8-Ball. Dave wants to know whether Shawna will give Daniel the time of day. Magic 8-Ball: "It is certain." I knew the Magic 8-Ball couldn't be trusted. For emphasis, we are actually shown the "IT IS CERTAIN" floating at the top of the ball, and then it's finally time for the immunity challenge.

Peachy takes the idol from the boys, noting that they've decked it out with blue feathers to mark it as theirs. Well, at least they didn't pee on it. That's something. Jeanne says that the ladies will be happy to remove the feathers later. Peachy acts amused. He then explains that the challenge is one of these complex rigmaroles in which the entire team is locked inside a cage. In order to get out, they have to untie knots to free a machete, and use the machete to cut a rope and free a board that is then slid horizontally to release a pole. They'll use the pole to get a couple of keys, and then get out through an escape hatch in the top of the cage. Note that Peachy says that when you have the machete, you have to use it to cut "the correct rope."
