The challenge in this episode is Serious Scramble. The island has suspended a giant scramble net above Skeleton Falls. The adventurers must haul themselves through the fast-flowing, icy water and up the difficult-to-climb net in a flat-out race with a twist. Claw and Sting both have five island torches, Venom still only have one - can they reverse their fortunes? Who will be taking on the Captain's Task? What else has the island got in store for the adventurers?
