In the episode, Indy was to fall asleep and have a dream intended to serve as a reference to Lagerlöf's most famous work. A children's book, "Nils Holgerssons Underbara Resa Genom Sverige" ("The Wonderful Adventures of Nils") concerns a boy that has been magically transformed by a gnome to five inches high as a punishment for his mischief. Nils then travels over most of Sweden, sitting on the back of a flying goose.
