Walt Disney's Uncle Scrooge #358

To keep his money safe from the Beagle Boys, Uncle Scrooge surreptitiously hides the cash in the eerie old castle of The Mad Duke of Duckburg. The Beagles get Scrooge to inadvertently lead them to the cash-filled castle, and then give Scrooge a case of amnesia. When the Beagles find themselves imprisoned by the Mad Duke's gauntlet of booby traps, there's no one to remember that they were ever there.
