A Mine Is a Terrible Thing to Waste

'''The two teams are sent into an abandoned mine, where one teammate takes charge of their team, and someone's disorder gets more out of hand. Someone throws the challenge to save their old team, leading to their elimination. Meanwhile, an old contestant falls in love with a new contestant and gives them a special reward, which leads to them quitting the competition and a former intern returning to their former team in their place.'''

Plot
The camera first pans to Brick and Lightning working out by lifting a log in place of a freeweight. Lighting shows off his muscles by using only one arm, compared to Brick using two. Jo tells the Confession Cam that now that she's on Team Rat, she has the girl's side to herself, so she can work out like the ancient olympians, in the nude. Her shadow is then seen in the cabin as a bird vomits at the sight of her. At breakfast, Chef is missing and the cupboards are bare. Chef then pops up and says to search in the walk-in freezer, but it turns out to be a refrigerated van which Chef drives to the challenge.

At the challenge, Chris is sending everyone into a mine to find a Gilded Chris Award in their team colour. However, it's radioactive, and each contestant is given a Geiger detector with a 30 minute timer, and that if they don't get out of their in time bad things will happen. He uses Dakota as an example who was in their for over 40 minutes and lost all her hair! Chris also gives them all heavy backpacks they have to wear in the mine until he says to drop them, and not allowed to look inside of them either. Lightning and the Rats make it to the mine shaft elevator first, but Lightning shouts and causes a localized cave-in on his team. The Maggots pass them and pick up the flashlights in the shaft. Sadly, the elevator crashes at the bottom, which forces the Rats to shimy down the cables. Brick goes first, and Jo throws him the jar of fireflies. Brick catches the jar with both hands, and begins to fall swiftly down the shaft. He is able to slow himself by using his legs, but Jo and Lightning speeding down after him cause him to drop the jar, allowing the fireflies to escape. Jo and Lightning chase after them, leaving Brick alone in the dark.

Meanwhile, the Maggots explore the caves, and Mike picks up a hat from the ground. He puts the hat on and instantly channels Manitoba Smith, his adventurous alter-ego. He quickly searches the area and finds rodent leavings which he licks to find which path they should take. He leads his team through the mine, eventually coming to a couple of minecarts. Mike and Cameron get in the first one, while Scott, Anne Maria and Zoey ride in the back. Back at the entrance, Brick hasn't moved far in the dark, but finds a leftover flashlight. When it turns on, he sees a giant mutant mole that chases him through the mine. Back on the Maggots team, the carts split, sending the first one ahead, while the rear cart ends up in a pool. In the pool, a shady figure grabs Anne Maria and takes her farther into the cave. Nearby, Mike is knocked out and Cameron tries to act like Jo to make him wake back up, which makes him turn back into his normal personality. Brick is then seen still running away from the mole, until he crashes into a rock. The mole smells Brick and reacts to his smelly boots, which Brick uses to his advantage. The camera then comes back to Anne Maria, who is surrounded by giant moles and the shady figure that captured her. He then reveals himself to her as Ezekiel. He is attracted to her and tries to flirt. Brick then catches up to his team, he thinks he is safe as he chased away the mole, until three other moles catch all three of the Rats and pull them down into the ground. Anne Maria is then seen ontop of a pile of things Ezekiel brings to her as gifts. The rest of the Maggots are seen back together and hear a cheerful scream from her nearby. Then follow the sound into Ezekiel's lair where Ezekiel has captured the Rats and has won Anne Maria over by giving her a giant "diamond". Jo then releases the fireflies to go into the mole's faces, which makes the Rats free again. Lighting then goes for their statue, but Ezekiel stops them. Chris then annouces it's time to drop the backpacks, which he reveals to actually be bombs. Scott then gets their statue and tries to get rid of it, but it lands in Anne Maria's hair, but she is to distracted by the "diamond" to care. Lighting strangles Ezekiel to get his statue again and they all get on mine carts. However, Mike is struggling trying to free Zoey and Cameron from the mole, so Brick takes pity on his old team and breaks the statue on the mole to knock it out. They then all get on the mine carts and ride away before their Geiger detector's timer ends.

Back above ground, the carts crashes out of the exit, and the Maggots Chris statue lands in front of Chris, who declares the Maggots as the winners. Chris then blows up the bombs sealing off the toxic waste coming from it, which also got the federals off their back. Chef then uses a powerful hose to wash off any waste. Later that night, Cameron asks Mike if he has Multiple Personality Disorder. Mike confesses to it, but Cameron makes a deal to help him control it if he helps him get rid of Scott, since he doesn't trust him. Mike quickly agrees to his plan.

At the campfire ceremony, Jo and Lighting are declared safe. The Toxic Marshamallow of Loserdom then goes to Brick because he saved the Maggots. His old team salutes him before he takes off. Anne Maria then runs over the the Hurl of Shame and quits, after receiving her large "diamond" that will make her rich. Chris then states that the "diamond" was actually just cubic zirconium, which is practically worthless. He then hurls them before Anne Maria could step off. Since the Maggots lost a player, Chris brings back intern Dakota to be her replacement.
