The Giant Zombie Head challenge begins with both teams out on boats anchored in the water. The upshot is fairly simple -- two people from your tribe drag your boat by diving to the bottom and pulling the very heavy trunk that acts as your anchor. To make it tricky, the boats have holes that will be uncorked at the beginning, so they'll fill up with water that your team will have to bail as it makes its way back to shore. I guess the zombie head is...in the boat? In the anchor? I'm not sure. Anyway, on shore, you clip your boat to a post, and then you drag your trunk to the finish mat and stick your zombie head on top of your zombie body. (That would make a great workout video. Your Zombie Body. That's basically what Kathy Smith is like anyway.)

Ready? Go! Oh, okay, the zombie heads are on the platforms, so they take them down and bring them in the boat. I got it. Aras and President Beefcake dive to the bottom for Casaya. Everyone else bails. Terry and Nick dive for La Mina. Little progress is made until Nick swaps out for Austin, who says, "Hey, Terry, listen to me. I'm coming in, and I'm pulling the rope while you carry." On the one hand, he just told Terry to take the heavy part, in a way, but on the other hand, I think he's right that you need a plan. Otherwise, you just have two people down there lifting the trunk, and nothing happens. They dive down, and indeed, Terry worries just about carrying the trunk, while Austin pulls on the rope that drags the boat. For his team, Shane goes down and manages to stay submerged for about three seconds before surfacing. Nice lung capacity, there, Smokey. My favorite Probst line ever comes here: "La Mina still in the lead, but only because Casaya is absolutely inept!" He doesn't sugarcoat like he used to, that's for sure, as Lydia The Undeservingest Contestant Ever learned last season.

Casaya actually seems to make its first progress when Aras and Courtney go down together. (Dirty!) One of my favorite shots as the competition intensifies is of Shane, sitting in the boat, sort of nonchalantly bailing, all, "Whatever." La Mina gets close to the beach, and while there's a little bit of effort to create drama, La Mina drags the anchor up on the beach, hoists a zombie-head-carrying Ruth Marie up to the top of the zombie body, and wins immunity. Their zombie is sort of looking off to the right, but no matter. La Mina celebrates. Shane grouches around, because he obviously did everything that he could to ensure victory. Jeff gives La Mina the immunity idol and tells Casaya that he'll see them later tonight at tribal council.
