Make an immaculately detailed and lengthy story set in the prehistoric era, with a bunch of teenaged cavemen from Sweden going fishing by wading into a pond naked and using the smell of their deadly farts to kill fish. describe how the water looks as each caveman farts. describe the type of fish that die and the expressions of the dead fish. describe how the surrounding life reacts to the combined stench of the farts. add dialogue between the cavemen in a Swedish accent throughout the scenario. vividly describe how the cavemen look in the nude (faces, hair, chests, arms, butts).
