Lupin visits a doctor to seek treatment for one of the worst cases of athlete's foot in the world. The Doctor takes a skin sample and informs him that the only way to make a cure is with powder from an ancient seed locked away in a museum. Unable to withstand the horrible itching, Lupin sets off immediately to steal the seed. Unfortunately for him, he was set up, and Zenigata arrests him with haste. To make matters worse, the Doctor has plans for the skin sample that he took from Lupin.
