Walt Disney's Uncle Scrooge Adventures #17

In "Lost Beneath the Sea," Uncle Scrooge and Donald Duck dive into the deep with a bathysphere to recover Scrooge's Old Number One Dime, only to discover the sunken ocean liner—and other ships—have been towed to a hidden undersea shipyard. There, four-armed Martians are salvaging iron for their iron-poor world, turning the ocean floor into a cosmic scrapyard. With Donald’s reporter instincts flaring and the mystery deepening, the hunt for treasure takes an unexpected turn beneath the waves.
