Season 4

Mickey's friends throw a surprise birthday party at Minnie's house. Minnie gives Mickey a piano, and the mice play a piano duet of "I Can't Give You Anything but Love, Baby". During the rest of the party the characters dance and play more songs.

Mickey works as a taxi driver in a large city. After losing his first customer in the street, Mickey picks up Minnie on her way to a music lesson, but the taxi gets a flat tire which Mickey is unable to repair. Pete appears as a traveling snake oil salesman who feeds a formula to the taxi. This makes the vehicle go out of control. Mickey, Minnie, and the taxi crash through a barn and end up covered in feathers.

Mickey is a castaway in the ocean and makes it ashore to a jungle island. After eating bananas, a piano washes ashore and Mickey plays it while dealing at first with bothersome wild animals, and later dangerous ones.

Mickey and Pluto go hunting for moose. Mickey accidentally shoots at Pluto with his shotgun and the dog plays dead. After this Mickey and Pluto encounter a real moose and are chased away.

While working as a delivery boy driving a cart filled with musical instruments, Mickey passes by Minnie's house. He sneaks up on her while she is outside doing her laundry. The two mice start dancing in the yard, but Mickey punches a bee hive onto the mule pulling the cart. The mule kicks the cart and the instruments land on the animals. Together they all play "Stars and Stripes Forever".

Mickey prepares for a date and leaves his house, but Pluto wants to come with him. Mickey tells Pluto to stay home and ties him to the dog house, but Pluto follows anyway, dragging the house behind him. At Minnie's house Mickey and Minnie play music, while outside Pluto chases a cat. The chaos eventually interrupts the date.

Mickey plays piano at a concert hall and is joined by Minnie singing "St. Louis Blues". Mickey later conducts a blues orchestra that proves to heavy for the stage.

Mickey and Pluto go fishing from a boat on a lake after sinking a sign that says "no fishing". The fish turn out to be very intelligent and play several pranks on the fishermen, including tying their fishing lines together. Eventually a police officer appears and, trying to stop Mickey from fishing, accidentally falls in the water. Mickey and Pluto make a speedy getaway.

Mickey sets up a radio station in the barn and hosts a music program. While Minnie, Horace, and Clarabelle perform, Mickey struggles to keep a cat family out of the barn who are intent on interrupting the broadcast.

Mickey and his friends spend a relaxing day at the beach going swimming and enjoying a picnic. When Pluto accidentally retrieves an aggressive octopus from the ocean, the party fights him off using techniques learned earlier in the day, such as Horace's spitting of watermelon seeds and ejecting jars of pickled olives from Clarabelle's throat.

Mickey mows his yard with a reel mower pulled by Pluto, while next door Minnie waters her garden. Mickey tricks Minnie by pretending to be a bird in a bird house, but instead he gets attacked by a cat. While Mickey and Minnie are playing a harmonica duet, Pluto chases after the cat, but the mower is still tied on to him and it cuts up everything in its path.

Mickey and Minnie take in an orphaned litter of kittens during Christmas time. The kittens harass Pluto, ransack the house, and skeletonize the Christmas tree.
