This episode contains several references to Mickey's Christmas Carol (1983), where Ebenezer Scrooge was portrayed by Scrooge himself.
The Ghost Of Christmas Past resembles Jiminy Cricket, who played the role of that character in Mickey's Christmas Carol (1983).
Mrs. Beakley makes reference to a holiday special called 'Christmas on Bear Mountain'. This was the title of the comic story that first introduced the character of Scrooge McDuck.
Professor Rhutt Betlah tries to get Scrooge to invest in an expedition to the Andes to search for the origin of a cubical rock. This is the plot of Carl Barks' 1949 Donald Duck comic book "Lost in the Andes."
