Screwy Squirrel escapes from the nut house and leads the guard dog on a long and ridiculous chase.

A crazy squirrel provokes a dog into trying to catch him throughout the picture.

Bugs Bunny is working in the display window of a department store when the manager tries to move him to the taxidermy department and have him stuffed.

Hugo and Rocky (caricatures of Edward G. Robinson and Peter Lorre) make it home to their hideout only to find Bugs already settled down there for the night.

Two buzzards suffer from acute food shortage and make up for it by cooking each other, or at least trying to.

The early worm barely escapes the bird, again. In search of a way to get rid of the bird, he enlists the help of a cat, but the bird is too smart for the cat.

Scheming mice Hubie and Bertie convince a cat that he is, in fact, a lion.

George and Junior are two hungry bears who try to make a meal out of a not too bright barnyard chicken.

The tree surgeon (a donkey) races to the giant sequoia, which isn't feeling well. His techniques, though, seem better suited to treating a person.

A bear, plagued with mice, lures a tiger cub (thinking it's a cat) to take care of the mice. The tiger scares the mice at first, but really has no interest in them, so the mice have fun with the bear, painting a glow-in-the-dark mouse on its bottom for the tiger to attack and leading the tiger on a house-wrecking chase with a steak. The tiger ends up hanging out and smoking cigars with the mice.

In this swing version of the famous tale, a small town is overrun with rats. The mayor (caricature of Lou Costello) is in a quandary. His phones are busy with demands to do something. He hears a voice say: "what you need is a Pied Piper." Looking up, he sees a young man with a trombone (Jimmy Durante) who claims that he can run every rat out of town for a fee. The mayor makes a deal with him, and the trombone player goes to work leading the rats out of town with the playing of his trombone, and he locks them in a cage. Returning to the mayor's office, he's handed a bag of peanuts and thrown out. Unable to get the reward promised, the Pied Piper puts on his "Hank Swoonatra" (Frank Sinatra) suit croons to the girls. He leads them aboard a swinging showboat and opens the cage full of rats and they return to town, where only the mayor is left. The rats swarm the mayor's office and give him a bad time for his treatment of the pied piper. Production Number: D-10 A Swing Symphony cartoon.
