鼻(はな)が長(なが)くなりました。

The old man wanted to change his poor life using the magic fan. First, he thought he would try making his own nose bigger. He fanned his own nose with the side that had the sun's picture, saying "Patapata." Then, the old man's nose gradually grew longer and longer. It reached the ceiling, grew even longer, and went out the window. The old man was surprised, but he immediately fanned his nose with the side that had the moon's picture. Then, his nose returned to its original length. The old man was convinced that if he used this fan, he could become rich.
