It first appeared in May 2002 as a two-part story in the issues #19 and #20 of Anders And & Co, a weekly published by Danish Disney licensee Egmont Group.
Little Helper used his head to break the plastic cover to let the gas out and the Money Bin wound up on the statue of Cornelius Coot.
The construction workers covered the hole with cement and gravel and the Money Bin was restored to its original location.
In his research for his website, Grøsfjeld had come upon newsgroup exchanges between Rosa and his fans regarding "the problem of the lost money in A Christmas for Shacktown".
In that classic Duck story by Carl Barks, Scrooge eventually loses all his money in a cave below his money bin, and the only access he has to it is by means of a little toy train (any other means would make the cave collapse and have Scrooge's money irretrievably fall into a reservoir of quicksand just below), bringing him a mere handful of coins and bills back on every trip in and out of the cave, which makes it clear for the characters at the end of the story that it will take Scrooge several hundreds years to regain his entire "three cubic acres of money".
However, upon Scrooge's next appearances in the one-pager Osogood Silver Polish and the long adventure story Only a Poor Old Man (both in Dell One Shot #386, March 1952) he has somehow, magically relocated all his fortunes back into the bin, a mystery for which Barks had never given an explanation.
On 11 January 1999, Grøsfjeld sent Rosa an e-mail containing his thoughts he had for a potential sequel to A Christmas for Shacktown:[2] "Somewhere you say that many fans and several editors for many years have asked you to do a sequel to the old Barks classic A Christmas for Shacktown (1951), where you were supposed to tell how $crooge managed to save his money from the deep pit much faster than he thought in the end of that story.
I need to check when the first Gyro story appeared in WDC&S, but if Christmas for Shacktown predates it, that is a GREAT idea!
- Don Rosa, e-mail to Sigvald Grøsfjeld Jr., 12 January 1999Yet another day later, Grøsfjeld had a few details worked out for Rosa:[2] "For some reason, Gyro [...] need[s] a little device to enter the pit the same way [...] [Huey, Dewey, and Louie]'s train did (reasons could be to get him/them samples of the soil in there, to help him/them drawing a detailed map of the situation inside the pit, or perhaps to install some other devices in there).
