Donald Duck & Co #16/1996

Petter Smart has discovered a biological copying machine, and Onkel Skrue sees a chance to escape his tedious social obligations by sending a duplicate of himself to endure them. But when a strange dream unsettles his plans, Skrue begins to question whether he really wants a copy of himself after all.

When Donald and the nephews are kidnapped and forced into an old diving bell to search for sunken Atlantis, a mishap sends them plummeting to the ocean floor—where they find themselves among ancient ruins, far from any rescue. With Kaptein Drønn’s mysterious presence looming, the crew must navigate the eerie depths before the pressure—or something else—claims them.
