Whilst blowing the didgeridoo, the sand beneath Scrooge crumbles to reveal an ancient cave.

He runs for shelter, and just barely makes it to the Dreamtale cave, which is then sealed off by the water and wet sand.

Much later, at the edge of the desert, Scrooge encounters Jabby again, sitting by a campfire at the end of another Dreamtale cave.

Scrooge realizes that the part of the Dreamtale that Jabby read him earlier actually foretold his adventure with the highwayman and the flash flood.

Jabby continues to tell Scrooge that the great platypus's firstborn was saved by Djuway, the bowerbird who builds his nest with shiny trinkets.

As a reward for returning the egg (the opal), Scrooge is allowed to "see his dream through the crystal eye".

As Scrooge leaves, singing happily to himself, Jabby looks at the Dreamtale, where there is a drawing resembling his money bin, and his nephews, Donald, Huey, Dewey and Louie.

In his author's note to the story, Don Rosa wrote that one of the characteristics that distinguish Scrooge from his nephew, Donald Duck, is the former's interest in archaeology and respect for the importance of history.

Rosa wanted to write an "origin story" for this aspect of Scrooge's character, and while doing so, realized that the Aboriginal Australians have "probably a greater sense of their historical continuity than anyone else in the world."
