Bingeing on too many burgers during lunch has given Ash a case of indigestion that stops him in his tracks. Unable to help their friend, Misty and Brock contemplate what to do until a miniature, seemingly magical, man shows up. He gives Ash two tablets and almost instantaneously cures Ash's aches! Curious about the cure, the gang head back to the small man's lab for a lesson in Pokémon medicine. Here they find out how this helpful fellow creates all kinds of useful potions with the aid of Shuckle and a speedy Pokémon named Spoopy!
