Walt Disney's månedshefte #8/1969

Donald Duck og Sjøormen follows Donald when an aptitude test declares him a natural detective, leading to a case involving the mysterious sinking of one of Uncle Scrooge's gold ships. As Donald dives into the investigation, his unexpected talent for music—unbeknownst to him—draws the attention of a massive sea serpent, forcing him to keep playing his instrument day after day to keep the creature at bay.

In "Hakkespetten," Donald Duck’s peace is shattered by a relentless woodpecker hammering away at a tree in his yard. Frustrated and sleepless, Donald takes matters into his own hands—turning to the local junkyard for a solution that’s as unconventional as it is memorable.
