'Toon star Roger is worried that his wife Jessica is playing pattycake with someone else, so the studio hires detective Eddie Valiant to snoop on her. But the stakes are quickly raised when Marvin Acme is found dead and Roger is the prime suspect.

The boys are taking Olive on a picnic. It's April 1, and Bluto plays a series of "jokes" on Popeye, though of course they go beyond the bounds of acceptability, particularly once they get to the picnic grounds; Bluto puts gasoline on the fire he asks Popeye to light and swaps a beehive for the lemonade. Bluto then launches a cruel joke against Olive and frames Popeye. The capper: he replaces Popeye's spinach with a joke can, and runs off with Olive for some canoeing. But Popeye gets the last laugh with an inflatable sea monster.

Olive Oyl's Farm is desparately in need of a farmhand. Fortunately, or unfortunately, the boys are driving by. They compete for the job. Chores: Getting water from a well, picking apples, shoeing a horse, gathering eggs. Popeye feeds a hen a little spinach, and she produces a mountain of eggs, which eventually end up all over Bluto. Bluto drops an anvil on Popeye, then goes after Olive against her wishes, chasing her into a succession of haystacks (where he finds a needle!). The chicken feeds Popeye his spinach, and he triumphs, sending Bluto into the pigpen (where the pigs won't have anything to do with him).

Popeye is climbing the Alps, and Olive is being hauled up behind him on a rope, taking pictures. Mountain guide Bluto spots them through binoculars, and goes crazy over Olive. He immediately intercepts them and tries to convince them they need a professional guide. Popeye resists, so Bluto uses a number of tricks: cutting the rope, burning a bridge they are crossing, using a magnet to break Popeye's climbing pick. Olive finally has had enough, and goes off with Bluto, who promptly gets her alone in a dark cave. Her screams bring Popeye, whose battle with Bluto carves a Mount Rushmore replica in a mountain-top. Bluto knocks Popeye into a snowbank, where a Saint Bernard dog revives him with spinach (after consulting a handy Popeye comic book). Popeye bashes Bluto into a mountain, forming a Paramount logo.

Tired of political rhetoric, Olive lays out her platform.

Popeye and Bluto are manning a fire station when the alarm comes in: it's Olive's house.

Popeye follows along behind the Mayflower in his own rowboat. He washes up on Plymouth Rock.

From Press Kit: Katnip's serenading of a girl cat is interrupted by a tough cat that runs him off and takes over.The love-lorn Katnip is determined to best the muscle-bound cat and enlists the aid of Herman. Herman, with bad-intentions, puts Katnip through a muscle-building course which consists of weight-lifting, bar-chinning and equipment rigged with high explosives.

Herman and Katnip in an art school.

Unaware that Katnip is the night watchman, Herman takes his three nephews to Paramount Pictures Studios on a sightseeing trip. They sneak in and find fake alligators and a fake King Kong, but a real live Katnip. Herman promises to make Katnip a movie star if he will let them go.
