Sea salts (1949)

'Mac' Bootle Beetle tells, referring to the ship's log, how he and captain Donald Duck were sole survivors of a shipwreck. The insect always suspected the duck wasn't quite fair, actually he was constantly cheated out of his rations share and used as angling bait without realizing it, both on the wreckage raft and after they drifted onto a deserted island, but ultimately they were rescued and stayed together for life, although even at their ripe age Donald.
