Speaking of Challenges, it's time for the Immunity Challenge. Probst greets them and Denise says that she's feeling the effects of some sort of bite. Probst points out that it's a possible opening for Abi, and she agrees. But if she has the Idol, she doesn't need it, right? I feel like she's forgetting her own cover story. Anyway, the challenge is to use planks to cross a rope bridge while collecting maze pieces. Once across, they will assemble the maze and use a ball to complete it.

They have two planks and have to crawl across a long rope ladder. So they have to place both planks and crawl out onto them, and then retrieve one plank and place it ahead, crawl onto that, lather, rinse, repeat. And along the way, they have to stop and untie ropes to retrieve the puzzle pieces. Everyone is fairly even as they start out, with Malcolm having a slight lead. Just as he is getting ready to finish the rope ladder, his plank comes off, the ropes split apart, and he falls onto the sand. He has to start over, and he's pissed. Everyone else has started assembling mazes. Abi is so bad at this; she puts pieces in places that make zero sense. Denise seems to be sailing along, although the nature of the puzzle is such that you could be nearly done and then suddenly have to pull out half of the pieces because it's all wrong. Malcolm is across the bridge for the second time and ready to start assembling his maze.

Denise finishes her maze but then realizes that the last piece she put in doesn't quite fit. It looks like it should, but it doesn't line up exactly, so it's wrong and she has to rearrange things. Lisa seems like she's not even close and I thought she was supposed to be the puzzle master. I'd like to see Penner try this. Malcolm suddenly gets all his pieces in and puts the ball through the maze. He won. Wow. That was quite a come-from-behind victory and he seemed really intent on winning for someone who already had an Idol.

Hey, Skupin hasn't nearly died in like half an episode. That means it's time for him to get injured again. And a rock pops in the fire while he's cooking and hits his foot, but he narrowly escapes death once again. I've got to say, popping rocks are dangerous. My brother got a hot rock in his EYEBALL when we were kids and my grandfather was an EMT and my mom and grandma had to hold him down on the couch while my grandpa used like a wire loop to scoop it out. I still have the willies and that was like thirty years ago. Also, one time a popped rock landed in my shoe and I got a blister. Okay, that's not quite at the same level.
