Richie Rich Inventions #20

Richie has arranged for a newspaper photographer to take pictures of an automatic power shovel named Superio. Richie introduces Irona to Superio, but he insults her, making it obvious that he considers her inferior. The photographer takes some shots of Irona, making Superio jealous. Superio makes several attempts to impress the photographer, but he ends up creating problems that Irona solves or fixes. Finally, Superio digs underneath a playhouse that Richie and Irona have entered, endangering their lives. Will Irona be able to save them?
