The story was first published in the Danish Anders And & Co. #2002-11; the first American publication was in Uncle Scrooge #328, in April 2004.
Miss Emily Quackfaster frees Scrooge and Donald simply by opening the door, and they chase Magica to the airport, where she is trying to return to Mount Vesuvius.
In the process, Scrooge and Donald forget various things, such as how to drive a car, how to walk, or even how to speak.
Donald reminds him that she is an enemy, so Scrooge resumes chase and they end up in a fight, during which Magica accidentally casts the spell on herself.
However, the effects of the spell on the Ducks have worn off, and thus Scrooge is lucid enough to trick Magica into giving him the dime back.
