Walt Disney's Comics and Stories #660

When the search for the missing girls leads Donald, Daisy, and the rest of the gang through a series of island puzzles and playful traps, they finally reunite at the mountain peak—only to face the enigmatic Master Mythos, who holds the key to the island’s strange secrets. With Uncle Scrooge’s curiosity matched only by Goofy’s optimism and the triplets’ sharp wits, the mystery deepens as the island itself seems to have a mind of its own.

Chip and Dale pay a visit to their Gran'daddy, who lives safely in a magical witch-proof tree deep in the Wicked Witch’s territory—though even the best defenses can’t keep out trouble when the twins’ antics stir up more than just a few feathers.

When Donald Duck accidentally stows away on a radio-controlled fighter during a tour of an aircraft carrier, he’s whisked into a startling parallel universe—leaving his nephews Huey, Dewey, and Louie to wonder what happened to their uncle. The boys soon find themselves caught in a mystery that blurs the line between reality and the unknown, all while Donald’s sudden disappearance leaves them scrambling to understand where he might be.
