Dr. Slump knows exactly what it is: a guy so committed to a ridiculous love potion scheme that he needs his android daughter's help, a magical island, and ingredients so gross they're funnier than the actual joke. The comedy isn't trying to be clever, it's just honest slapstick about a middle-aged inventor's complete lack of game. You're watching someone fail upward through pure determination and weird dad energy.
Dr. Slump is hopelessly in love with Ms. Yamabuki, but he cannot bring himself to confess. Everything changes when he comes across a videotape from his late father explaining how to brew a potion that makes anyone fall for him. The catch? It calls for Dr. Slump's own nose dirt and tears from King Gyasuka, the great evil ruler said to live on Wonder Island. Riding a newly invented vehicle called PingPong, with the powerful Arale and Gaccahn at his side, Dr. Slump sets off on a wacky quest to collect the ingredients. The problem is that he is thoroughly unreliable, to the point of mistaking a dryer for a light gun. The result is a goofy comedy adventure built around whether his romantic wish can come true.
