The New Neighbor

Donald's sister Dumbella sends her three sons Huey, Dewey, and Louie to visit their uncle Donald. They prove to be quite a handful for Donald, even with help from his book on child rearing.

Minnie's old friend, Mortimer Mouse, drops in on Mickey and Minnie's picnic. His practical jokes and coming on to Minnie soon have Mickey stewing, and their car isn't happy either. When Mortimer gets a nearby bull enraged and takes off, the car comes to the rescue after Mickey gets tangled up in a red blanket.

Tom subjects Jerry to his usual harassment; but the cat finds a new enemy, and the mouse finds a new friend, in the canary of the house.

Tom fights with another cat over Jerry.

While streetworker Mickey romances Minnie, Mickey's nephews Morty and Ferdie take control of his steamroller and it's full speed ahead on a very destructive ride.

Mammy Two-Shoes threatens to throw Tom out of the house if he makes a mess. Jerry sees an opportunity to rid himself of his feline nemesis.
