The film opens with Bosko taking a bath while whistling "Singin' in the Bathtub". A series of gags allows him to play the shower spray like a harp, pull up his pants by tugging his hair, and give the limelight to the bathtub itself which stands on its hind feet to perform a dance.
Bosko is a construction worker who impresses Honey by making music from everything in sight, including a decapitated mouse, a typewriter and a goat filled with hot air.
Wile E. Coyote (Fallious-flatius) uses an ACME Weather Control Kit to try and catch Road Runner (Speedius-gonzalicus) through various weather-related tricks.

Bosko is a brave little boxer who battles the champion, Gas House Harry. The enormous brute proves a bit much, even for a plucky underdog. Some of the animation is later reused in "Bosko's Parlor Pranks" by M.G.M. in 1934.
While ice-skating on a frozen pond, Bosko and his dog discover a baby abandoned in the snow.

A mannequin in the city dump improvises a working piano from junk, then plays and sings the title song. Various discarded items join in with song or dance.
A circus parade, to the title tune. Next, a series of sideshow acts: the wild boy, the rubber man, siamese twin pigs, a tattooed man, a hula-dancing hippo, an Indian snake (or goat) charmer. Into the ring, we have a hippo riding a horse (much to the horse's dismay), a high-wire act (again, to the title song), and finally a lion tamer.
Freddy comes to a party and is a hit; he then goes on to be the star quarterback at the football game.
The last Goopy Geer cartoon. The king returns to his castle, and asks where the queen is; she's in the parlor, and won't be seen, according to the title song. He goes to his throne and summons his jester, Goopy Geer. A black knight arrives and threatens one of the young ladies in court; Goopy Geer fights him off, first with an ax, then in armor from kitchen utensils, then butting him with a mounted animal head, which makes the knight's armor fall apart. He pulls it together again and runs away.
Goopy, a dog of no particular personality, but a crackerjack piano player, plays several songs on the stage of a nightclub. We spend a fair amount of time watching the patrons and staff of the nightclub.
