The flashback continues. The girl pleads, "GO AHEAD, TAKE WHATEVER YOU WANT... BUT PLEASE... SOME WATER!?" The pirates ignore her pleas, saying, "PATIENCE LITTLE LADY! FIRST, WE GOTTA SEE YOUR TREASURE!" While they are distracted opening the chest, the girl quickly climbs onto their larger pirate ship. She smiles cheerfully and waves, shouting, "TAKE THE WHOLE SHIP! IT'S ALL YOURS! HEE HEE." The pirates open the chest only to find it completely empty, screaming in shock, "HEY!!! SHE'S LEAVING WITH OUR SHIP... AND OUR TREASURE!! HEY! THIS CHEST IS EMPTY!!!

The flashback concludes. Standing on the pirates' stolen ship, the girl looks up at the sky and predicts the weather: "DARK CLOUDS COMING IN LOW FROM THE SOUTH... THAT MEANS A COLD FRONT, FOLKS... WITH A STRONG LIKELIHOOD OF VIOLENT SHOWERS... THERE'S A SQUALL LINE HEADING THIS WAY... SMALL VESSELS SHOULD TAKE PRECAUTIONS AGAINST CAPSIZING." Right on cue, a massive wave crashes down and capsizes the pirates' small boat with a loud "KRAK!!!!" and "ARRGH!!!" sound. The girl sails away safely, waving and shouting, "BINGO! SO LONG! AND THANKS FOR THE TREASURE!" while the pirates drown, screaming, "S-SHE TRICKED US!!! WE'LL GET YOU FOR THIS!
