Cork Graham (the expedition leader), Meghan Heaney-Grier (the expedition dive master), Jeremy Whalen (the ship's mechanic), Bryan Fry (the herpetologist) and Keith "Cappy" Plaskett (the boat's captain) will come across a cave system as seen in the clip below.

The team will walk through to the other side of where they entered since they see light pouring in, which indicates the cave they are in has multiple entrances.

"That's crazy, just like a passage," Heaney-Grier comments while walking through the cave.

Cave systems form over time due to "natural forces" such as the weather like extreme rainstorms. The cave systems are quite complex since they can span large areas, but they can be quite dangerous since the rocks within them can be faulty and collapse at any given time.

"This blend of secrecy and danger makes a cave system the perfect maze, ideal for holding in secrets over centuries," which is why the team is exploring them.

The treasure hunters will also experience some issues with their boat. They will spring a leak, which will lead to a bluesy song from "Cappy" as seen below in the other exclusive clip. He even plays a harmonica!

Treasure Quest: Snake Island concludes its first season tonight, Aug. 21, on the Discovery Channel at 10 p.m. ET so make sure you tune in to see what else the team will come across.
