Inside Mario Brothers Plumbing, Mario is unable to concentrate on fixing a pipe due to a group of people running back and forth outside. Shortly afterwards, someone comes running down the stairs and enters through the front door. The person in question is Rob Stone, a teenager in a leather jacket and sunglasses with a guitar. Rob tells Mario that he needs to be hidden, and Mario tells him that he'll do what he can to help.
Luigi enters through the front door, commenting about the mob of people outside. He then sees Rob and is shocked to see a teen heart throb at Mario Brothers Plumbing.
Mario, Luigi and Rob sit down to eat pizza, when Mario comments that he didn't know that Rob even played guitar. Rob confesses that he doesn't play, and merely carries a guitar around for his image. Rob thanks Mario and Luigi for letting him hide in their home, because he couldn't deal with his mob of fans.
Mario asks Rob to pass him a napkin, but Luigi interferes, telling Mario that this is Rob Stone they're dealing with, and insists that he reask his question by saying please. Rob tells them to stop making a fuss, because even though he may be a beloved person, he's still "almost ordinary".
Rob announces that he has to get going, but he can't leave, due to the mob of people still hanging around outside. Mario and Luigi try to offer him some of their pizza, but he declines because he has to watch his weight.
However, Mario comes up with a plan; having Rob dress up in Luigi's clothes, while Luigi dresses up in Rob's. Dressed as a plumber, Luigi tells Rob that nobody will pay attention to him. As a thank-you, Rob tells Mario and Luigi that they can call his agent to get free tickets to his next performance.
After Rob leaves, Luigi realizes that he left his guitar behind, and rushes after Rob to give it back to him. Before Mario can stop him, Luigi is chased around by the mob of people outside, who mistake him for Rob Stone. While watching Luigi run around outside through the basement window, Mario comments that being famous must keep a person in good shape.
