An emaciated canary, singing like Frank Sinatra, is getting on the nerves of a pipe-puffing parrot, who speaks like Bing Crosby. The parrot spots Sylvester, foraging through the trash. Telling the cat he needs more vitamins (which the canary has been swallowing in bulk), he lures the cat inside to snare the canary. The straightforward approach fails (the canary bops him in the nose). He carves a female canary from soap, lures Frankie there; the birds slide down a greased counter, into the sink, and down the drain, but only the soap bird goes through the pipe and down Sylvester's throat. A trail of birdseed into the garage seems to work, but Frankie jacks Sylvester's mouth open. Sylvester laces the vitamins with buckshot; like all cartoon magnets, his attracts everything metal in sight except his prey.
Henery Hawk, making his first appearance in a Warner Bros. cartoon, refuses the worm his mother is trying to feed him; after all, he's a chicken hawk. That night, he sneaks out to the hen house, but comes up against a protective rooster.

A firefly with a miner's lighted helmet explores a camper's tent and the various people-sized items that, from his perspective, are gigantic, then utters the cartoon's single line of dialog.

Ping pong: The spectators eyes follow the ball... Ski jump: A long, long chute and a very short jump. Track: The hurdlers climb the hurdles like ladders. Swimming: The women's champion turns out to be a mermaid. A men's champion demonstrates strokes, ending with the crawl (on the bottom of the pool, on all fours). We see dives, ending with a seedy bar. Crew: We pull back from the first three precision rowers to see a real mess. Bicycle track racing: "Monotonous, isn't it?" Baseball: A talkative catcher gets knocked back by the ball. Football: Avery Memorial Stadium, with every seat on the 50-yard line one row wide and hundreds tall. On field: The QB calls signals and hops around. A ref emerges from under a pileup: "Is it a touchdown? Mmm, could be." The play is diagrammed into a huge tangle. Auto racing: The winner is...

Then, The Rains Came. A collision with an iceberg is narrowly averted. Land is sighted. The pilgrims are welcomed by Chief Sitting Bull.

Back in prehistoric times, a thundering earthquake splits a mountain wide open, and out hops the minah bird, to alternately bedevil, mystify and rescue Inki as he hunts dinosaurs. Meanwhile, a pelt-bedecked caveman persists in his attempts to make a pot of stew, which keeps getting overturned each time Inki, dinosaur, sabre-tooth tiger and minah bird zip past.
