In which our heroes strap on their hat-torches, hook in their carabiners, tug twice if anything goes wrong and descend deep into the bowels of the earth. We discuss those giant holes in the ground otherwise known as caves as Jackson does his best to defend the reputation of hermits, Zoe forgets some key things about bats, and Duscher just wishes everyone knew what a sewer was so he could stop explaining it. Join the gang as they host their very own survivor cave challenge where it all descends into madness and no one really wins. It's dark, it's wet, it's full of bats and mole people, and the surface world is getting further and further away.
