Immunity Challenge! Probst takes the immunity necklace back from Bob and places it on the ridiculous official immunity necklace holder. I've only just noticed that it even existed, but I don't know how I managed to miss it all those times. It's gigantic and has a skull on top! Probst explains the challenge: contestants must memorize a mask and run through an obstacle course to another blank mask, bringing three bags of puzzles pieces with them. They will then use the pieces to build the mask so it looks like the first one. Also, they will be blind-folded. Yikes. That sounds really hard.

There's a hilarious moment when the contestants, now blind-folded, step up to their masks and Sugar gets on the wrong side. She's totally going to lose this one. I doubt she'll even bother to try. Probst says go, and the contestants "memorize" their masks by feeling them. Bob carefully feels his mask up, but Sugar and Matty decide to grab a bag and go. The others soon follow. Matty leaves his bag and goes back for more, while Ken, Sugar, and Bob decide to put their pieces on the mask first. As for Crystal, she manages to bring her challenge suckitude to amazing new lows as she wanders off the course. Probst decides to play nice and lets her know that she is in the wrong lane and "completely off-track." If that had happened in the Olympics she never competed in, it would have been an automatic DQ. Crystal tries to get back in her lane, but goes in the wrong direction. She's never going to get back.

Susie makes it to her mask, while Crystal is still in the wrong lane. But at least, Probst points out, she's heading in the right direction. Probst is having the greatest time ever with her, as she lifts a giant leg up and over the course boundary and he yells that she's off the course again. She goes back, and he says she's back on. Why is he helping her? This would have been so much more fun if Crystal had wandered off and started trying to complete other people's masks or just left the course entirely. Meanwhile, Matty has all three bags at his mask and starts working on the mask. Crystal "miraculously," Probst points out, is nearly at her mask. And she makes it! Ken, on the other hand, hits his head on a pole.

Bob and Susie head back for their third and second bags. Bob finds his when he basically charges into his wood platform, head-first. Ouch. "There we are!" he says, sounding concussed. But at least he found it -- Susie has pulled a Crystal and wandered off the course. Okay, they should do every challenge blind-folded. This is hilarious. Bob makes it back to the blank mask with his last bag while Matty decides to go back to his mask and check it again. That could lose him the challenge. Bob thinks he's solved his puzzle, but Probst says no. Meanwhile, Ken has all three bags at his blank mask. And Crystal is still in it to lose it. As for Susie, I think she's in Kenya.
