Friends are gathered at Loopy's house and she tells a tale.
Once upon a time in a beautiful palace, there lived a king named Harry and his two daughter, Petty and Loopy. Princess Loopy said that she will marry a prince who brings her all the precious treasures of the world. So the princes of the near kingdoms all came with the precious treasures to marry her. Prince Eddy brings an interesting robot Rody, Prince Tongtong brings a magic marble, and Prince Poby brings a magic violin... But none of them were enough to win Princess Loopy's heart.
Finally Prince Pororo comes and takes Princess Loopy on a plane. Princess Loopy was taken by the plane ride, and picks Prince Pororo to be her groom.
But when Pororo listens to this he stops Loopy and shouts 'Wait! What if I want to marry pretty Princess Petty?' Loopy gets angry. What will happen in the end?
