At the Katnip Kollege, we see a roomful of cats taking a course in Swingology. Everyone swings except Johnny, who can't cut it and has to sit in the dunce chair. Miss Kitty Bright tells him to look her up when he learns how to swing. Finally, listening to the pendulum clock at night, Johnny gets the beat. He rushes out to where everyone is playing and sings "Easy As Rollin' Off a Log" to Kitty Bright. She joins in; he grabs a trumpet for an instrumental break, with the complete band. They both fall off a log; she covers him with kisses.

Another entry in the "books come alive" subgenre, with possibly more books coming alive than any other. We begin with some musical numbers, notably the various pages of Green Pastures all joining in on a song, The Thin Man entering The White House Cookbook and exiting much fatter, and The House of Seven (Clark) Gables singing backup to Old King Cole. The Three Musketeers break loose, become Three Men on a Horse, grab the Seven Keys to Baldpate, and set the Prisoner of Zenda free. They are soon chased by horsemen from The Charge of the Light Brigade and Under Two Flags and beset by the cannons of All Quiet on the Western Front. All this disturbs the sleep of Rip Van Winkle, who opens Hurricane so that everyone is (all together now) Gone with the Wind.
