Gyro's list of inventions that turned bad mentions Armstrong, Time Tub and Robotica and cogs. The first three were inventions from the original DuckTales (1987) series that had actually gone out of control, while the cogs were antagonists from the Disney video game Toontown Online (2003).
This episode introduces Scrooge's number one dime, the first dime he ever earned. It was given to him back in Scotland as payment for cleaning a very muddy pair of boots.

Scrooge McDuck's secretary, Mrs. Quackfaster (from the Disney comics), had been renamed Mrs Featherly in DuckTales (1987). This series gives her her comic-accurate name.
Louie is seen drinking a soft drink called "Pep." A chewing gum called Pep was a major plot point in an episode from the original DuckTales (1987) series.
