Walt Disney's Comics and Stories #4 (244)

When sabotage keeps stalling Duckburg’s missile program, the unlikely trio of Donald Duck and his nephews Huey, Dewey, and Louie take matters into their own hands—despite being just broom boys at the base. With Gyro Gearloose’s inventions and the mysterious Professor Slyrat lurking nearby, things get even more explosive when General Blagg demands results, fast.

In "Mickey's Strange Mission," Mickey Mouse, Goofy, and the eccentric Blackstone P. Percival stumble upon a booby-trapped canyon while tracking down Black Pete, who’s due to inherit a fortune under strict conditions. With the cautious old miner refusing to believe Pete’s true intentions, Mickey must navigate the treacherous traps not just to protect the gold, but to keep Pete from losing his inheritance—again—by crossing the line one more time.
