Season 6

Mickey works at the construction site of a steel frame skyscraper while Minnie sells box lunches to the workmen. Pete, the foreman, harasses Minnie and later steals Mickey's lunch.

A mad scientist named Dr. XXX captures Mickey's dog Pluto and takes him to his laboratory. Mickey follows and tries to save Pluto.

Pluto saves a litter of kittens from drowning, but later becomes jealous when Mickey takes the kittens into the house and are treated like part of the family. As Pluto tries to guard his territory from the kittens, he causes a ruckus and Mickey throws him out of the house. Later the kittens come outside and fall down a well, giving Pluto a moral dilemma of whether or not to save them a second time.

Mickey and his friends put on a low-budget stage play adaptation of Uncle Tom's Cabin. The use of actual dogs in place of the bloodhounds which chase Eliza across the ice floes leads to chaos as the dogs chase a cat through the orchestra pit.

Musical set in medieval Europe; a king arranges for his daughter (Minnie) to marry a visiting prince (Dippy Dawg). When Minnie refuses, the king locks her in a tower. Mickey appears as a traveling minstrel and rescues Minnie from the tower, but the king discovers them before they can get away and condemns Mickey to death, anachronistically by guillotine. Just as Mickey is about to be killed, Minnie confesses her love for Mickey, at which point the king orders a duel between Dippy and Mickey. Mickey tricks Dippy and cuts off his spear in the guillotine and chases him out of the castle.

Mickey works as a courier pilot for the airmail service and helps arrest Pete who is wanted as a mail bandit.

Mickey builds and trains a boxing robot to face the Kongo Killer, a trained boxing gorilla. Minnie discovers that the sound of a horn makes the robot "go crazy", an effect that Mickey finds undesirable. However, when the robot is being beaten in the match, Minnie uses a horn to motivate the robot to win.

Set at Grauman's Chinese Theater in Hollywood, Mickey and his friends attend the premier of one of his films, the meta-fictional Galloping Romance, which is based on The Cactus Kid. Cartoon versions of movie stars also attend the show and enjoy it immensely. After the film, Mickey receives praise from many of the show's attendees, but when Greta Garbo kisses him, Mickey awakes and discovers it was a dream.

Mickey and Pluto pay visits to their respective sweethearts, Minnie and Fifi. While Mickey and Minnie are preoccupied playing the piano (playing the song "Puppy Love"), Pluto steals the box of chocolates that Mickey brought for Minnie and gives it to Fifi. He then replaces the chocolate with a bone and returns the box. Both relationships turn cold when Minnie finds the bone, but she later discovers the half-eaten chocolate and reconciles with Mickey.

Mickey is a jockey in a steeplechase; his horse, Thunderbolt, is sponsored by Colonel Rolfe. After Mickey promises to win the race, the horse discovers a bottle of moonshine in the stable and gets drunk. Instead of the horse, Mickey dresses up two of the stable hands like a horse, and with the help of a pursuing swarm of bees, manage to win the race.

Mickey gets a job at Tony's Pet Store, and while the owner is away Minnie pays a visit to stay with Mickey. A movie ape kept at the store becomes inspired by the 1933 film King Kong, escapes his cage, abducts Minnie, and climbs a tower of boxes. A swarm of birds and other animals fight the ape and create a huge mess at the store. Mickey and Minnie run away just in time before the owner returns.

Mickey tells the story Jack and the Beanstalk to the mice children and inserts himself into the story as Jack. The film takes over Mickey's narration as he visits "Giantland" and meets the giant.
