Commercials, and then we are at Moto on Day 18, where Boo is eating...a bowl of cereal? That's what it looks like, anyway, although I think I missed the Frosted Flakes reward. Boo says that losing the reward challenge proved to them that they're going to have to work a little harder to keep winning immunity. He insists that it's extra-important for Yau Man that they win immunity, because of course, Yau Man will be out if they lose. I'm impressed that Boo has been successfully given that impression, which I don't think is accurate. "He's got to be the weakest, physically, out of all of us," adds Boo.

As for Yau Man, he tells us he feels good -- he's allied with the "very strong and honorable" Earl, and of course, he has the idol. So his priority right now is just making it to the merge. He tells us that he was trying to think about not letting anyone know that he had the idol, after which he says he had "a really evil thought." And what was this really evil thought? He decided to make a fake idol and bury it where the idol is meant to be, so that someone else might find it and think he or she had it, and at least not know that Yau Man had it. He makes an "idol" out of a coconut shell with a face painted on it, and...I'm not sure I think it would fool anyone with six brain cells to rub together, even/especially with the letters "I.I." that Yau Man paints on it just to make sure you know it's...the Immunity Idol. Nevertheless, he's at least making an effort. He wraps his "idol" in a cloth, and as he slips it into his bag, he says to the camera, "There are so many immunity idols running around here!" He's so cute. And then, when Michelle and Stacy are sleeping, Yau Man buries it good and shallow, saying he just hopes someone will wind up with a fake. He explains that the challenge is important, because he's "always a target," even though he has the idol. He hopes he won't have to use it.

We move to the challenge course, where the tribes have already gathered. Jeff asks how they're doing, and then he welcomes Earl back from Exile Island. Jeff takes back immunity from Moto -- it's "back up for grabs!" In today's challenge, one person for each team will act as the "caller," while everybody else is blindfolded. One at a time, the caller will lead people out into an area where there are five skulls hanging free from above. The caller has to guide you through smashing a skull, piñata-style, which will not only splatter paint everywhere (according to the demo clip), but also drop a tied-together pack of tiles. With your blindfold still on, you find the tiles on the ground and take them over to your team's puzzle table, and then run back to the team. When all the tiles have been delivered, the team can take the blindfolds off and run to the table to unscramble the tiles into a two-word phrase. Jeff notes that you are allowed to switch callers if, for some reason, you feel like you need to. Like, for instance, if you put your most annoying person up there first.
