Flapjack and K'nuckles go to a secret swimming hole K'nuckles' adventurer hat stolen by a chimpanzee named Cameron. Flapjack and K'nuckles are then kidnapped by the chimps and taken to their village to be possibly sacrificed, but then a mysterious woman in love with K'nuckles helps him find his hat at the "secret place" and K'nuckles must walk across the "Death Vine," a vine that is suspended over an active volcano to get his hat back. K'nuckles eventually gets his hat back, but the woman says he destroyed all her years of research and tried to tell the Chimpanzee Leader to throw the hat into the lava. K'nuckles throws her into the volcano and she shoots out all the way to another island.
In the end, it turns out that all the chimpanzees can talk, to the shock of Flapjack and K'nuckles. They also reveal they chose not to do it when they were around Dr. Proctor, who they didn't like and found to be very boring and annoying. Cameron even confessed that's not his name at all, it's George. They thank K'nuckles and Flapjack for getting rid of Proctor and give the pirate his hat back.
