Carl Barks Library of Walt Disney's Donald Duck Adventures in Color #7

In "Donald Duck and the Ghost of the Grotto," the ducks find themselves in the West Indies, running a kelp-gathering boat when they hear whispers of an armored man who emerges every fifty years to steal a small boy. When Dewey is taken, Donald, Scrooge, and the others must brave a treacherous coral reef grotto beneath a decaying galleon, guarded by a massive octopus, in a desperate bid to rescue him.

In "Adventure Down Under," Donald Duck, under a curious spell, becomes convinced he’s a kangaroo and sets off to Australia with Huey, Dewey, and Louie—only to find himself tangled in a wild hunt for Mournful Mary, the so-called queen of the kangaroos. As the ducks navigate the outback’s strange wonders, Donald’s delusion leads them straight into the clutches of mysterious aboriginal tribesmen.
