To your disbelief, you fid a sword floating in the river. Very weird.
Anyway, you pick it up and start hacking at the Poo Piranhas, but
they are so small you only succeed in stirring up the stream, making
them angrier. So you turn the sword so that your now hitting them
with the flat part, knocking them senseless. Then you feel an intense
heat right behind you. You turn around and, to your astonishment, see
that the lady found a flame thrower and was torching up the Poo
Piranhas. You just stand aside and try not to get torched yourself
and let her take care of them. After a few minutes, she had torched
them all and their burnt little bodies floating
downstream.
