Cave of Treacherous Terror

The Cave of Treacherous Terror is a cave on the "haunted" Boney Island. It has appeared only in one episode, Trial by Tri-Armed Triathlon, and appears to be a home for many animals, including spiders, bats, and Woolly Beavers.

It is used in the second challenge in Trial by Tri-Armed Triathlon, where the remaining campers (Owen, Geoff, Duncan, LeShawna, Gwen and Heather) must get the remains of the Tiki Idol into the cave, which is presumably the place where the Idol was originally held. Gwen and Geoff were the only team to successfully put their piece of the tiki idol back into the cave. Despite Boney Island being visited in Up the Creek, and the idol supposedly coming from here, the cave was not seen in that episode.
