Walt Disney's Comics and Stories #11 (155)

Pluto’s fear of firecrackers makes the Fourth of July a nightmare—until he steps in to protect Mickey, Minnie, Morty, and Ferdie when he thinks one is about to go off right in front of them. A brave heart beats beneath his anxious bark, and this holiday becomes a test of courage he never expected.

Mickey and Goofy join Professor Finney aboard Black Pete’s S.S. Octopus on a quest for a rare shark, but when they stumble upon a map leading to a mysterious whirlpool marked with an "X," the adventure takes a surprising turn—especially when Black Pete gets his hands on the clue.
