The story involves Popeye and Olive on a life raft playing checkers. They see a ship adrift, thinking they are rescued. But the ship is haunted, deserted, and has a crew of ghosts with English accents (voiced by Mercer) who do not like the idea of returning to civilization, so they wreak havoc on Popeye and Olive. While Popeye is hiding in the ship's galley to avoid a mob of sword-wielding ghosts, he sees a jar of "ye king's spinach". When Popeye consumes the spinach, he becomes invisible, allowing him to punch the ghosts flat and Olive to sew them together to create a new sail. Popeye and Olive then sail off in the sunset as the cartoon ends - and the theatrical series with it.
- Final theatrical short appearance of Popeye and Olive Oyl.
- Because this cartoon is in the public domain in the United States, it has been made available on various DVD compilations of theatrical Popeye cartoons as well as streaming video from various web sites. A restored authorized DVD release is planned from Warner Home Video in the Popeye the Sailor series of DVD collections.
