Les invisibles

A driver on a non-stop race from New York to San Francisco gets detoured to Hollywood, where he winds up working as a publicity man for a movie studio and assigned to revive the career of a beautiful but fading star.

Mickey heads over to see Minnie, but Pluto won't leave him alone. He gets there and watches through the window, standing on Pluto, while Minnie plays piano. Pluto runs off to chase a cat and leaves Mickey stuck in the window. Minnie has him in, and he dances to her playing. Pluto chases the cat into the house and causes havoc. The chase leads into the piano, where Pluto picks up the player-piano roll as an extended tail, and the destruction continues.

A greedy man tries to get rid of his mother by putting her in an old folks home until he discovers she has a fortune in stock certificates.

Masked bandit Bimbo holds up a train carrying someone tougher… Betty Boop (with dog's ears), played by a different, deeper-voiced actress.

Koko The Clown continually interrupts an animator, who turns his attention to trapping the clown.

Mickey's film is having a premiere, and all the stars turn out at the Chinese Theatre. Among those shown: Laurel and Hardy, the Marx Brothers, Jimmy Durante, Clark Gable, Sid Grauman, Mae West. The picture, Galloping Romance (Pegleg Pete kidnaps Minnie, and Mickey gives chase on a variety of animals), starts, and everyone in the audience sways along to the music, then rolls in the aisles with laughter. After, everyone comes on stage to congratulate Mickey; Garbo smothers him with kisses.

Mickey's a shovel operator and laborer at a construction site; Minnie is delivering box lunches; Pete is the foreman. Mickey pays more attention to Minnie than to his work, and keeps having accidents (mostly involving the blueprints Pete is holding). Pete steals Mickey's lunch, so Minnie offers him one on the house. While he's eating, Pete kidnaps Minnie; Mickey fights him, but the tide turns when Minnie dumps a load of hot rivets into Pete's pants...

Oswald the Rabbit comes to the rescue when a peg-legged sheik abducts his girlfriend and brings her to a mysterious pyramid filled with walking skeletons, animate hieroglyphics and other strange sights.

While Bimbo and Koko admire Betty, their experiment becomes a monster.

Betty Boop hosts a Hallowe'en party with a few uninvited guests.

This might be termed a comedy of errors, for the overzealousness of a lot of good-hearted simple folks places them in a rather embarrassing position. Lillie Green, who keeps a boarding house, receives a letter from her old school chum, Polly Brown, whom sin hasn't seen in years, to the effect that as Lillie has never seen her little darling daughter, she will send her for a few days' visit, asking that someone meet the child at the 3:40 train. Lillie's boarders are a bunch of kind-hearted bachelors, who at once prepare to give the "Little Darling" the time of her life, buying a load of toys, etc., for her amusement, also procuring a baby carriage with which to meet her at the train. You may imagine their embarrassment when they find that Tootsie, instead of being a baby, proves to be a handsome young lady of seventeen, whose tastes run rather to garden gates, shady lanes and quiet nooks, than toys.
