In the caves, the echo sound the cave is named for causes Gore to mistake the sound for the creature. He fires a shotgun wildly, which causes a cave-in that leaves the boys trapped in the caverns; all others escape before the cave-in and Gore believes ManBearPig is at fault. While the boys search for a way out of the cave, Cartman discovers a small cavern filled with what appears to be treasure. Greedily, he starts swallowing the treasure piece-by-piece to smuggle it out of the cave.
