Dr.Slump loves Ms.Yamabuki. But he cannot confess it to her. One day they find a videotape of Dr.Slump&rsquo;s father. It is about how to make a medicine. If one takes it, he or she comes to love Dr.Slump. (What a great father!!) It says that the nose dirt of Dr.Slump and the tears of King Gyasuka is required for making such medicine. (What disgusting! Does it really work?) Anyway, inventing a vehicle named PingPong, Dr. Slump go forward to Under Island where Great Evil King Gyasuka is said to dwell. Dr.Slump is such a unreliable man as to mistake dryer to light gun. But with powerful Arale and Gaccahn with him, there won&rsquo;t be anything to be afraid of. Well, will his wish come true!?<br><br> (Source: Official Website)
