S1·E42 The Secret of Dr. Flappe

It turns out that Ha-chan had the Dragon Ball. He had hidden it, knowing that the villagers would be killed once they found it. The mayor recommends that Ha-chan stay in the village, but Ha-chan says it is dangerous, because of his self-destruct mechanism. In order to get Ha-chan’s self-destruct mechanism removed, they visit his creator, Dr. Flappe. But Murasaki has gone there ahead of them! He steals Goku’s luggage, in an attempt to find the Dragon Balls. However, it only contained Goku’s bento (single-portion meal)?! The self-destruct mechanism is safely removed.
