Dr. Slump and Arale-chan: Hello! Wonder Island

Synopsis

Dr. Slump has feelings for Ms. Yamabuki but can't bring himself to confess. One day, they come across a videotape left by Dr. Slump's father, which explains how to make a special medicine. Anyone who takes it will fall in love with Dr. Slump. (What a wonderful father!) The recipe calls for Dr. Slump's nose dirt and the tears of King Gyasuka. (How disgusting! Does it even work?) Anyway, Dr. Slump builds a vehicle called PingPong and heads to Under Island, where the Great Evil King Gyasuka supposedly lives. Dr. Slump is so unreliable that he mistakes a hair dryer for a ray gun. But with the powerful Arale and Gaccahn by his side, there's nothing to fear. So, will his wish come true?
