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 house party. While Minnie plays piano and the guests dance, Mickey, Goofy, and Horace prepare a snack, which is brought out to much fanfare and immediately devoured. A band forms and plays Scott Joplin's The Entertainer; Mickey dances with Patricia Pig and various inanimate objects also dance, while all cry "Whoopee!" from time to time. The police come to break up the party.

Mickey hosts an amateur hour radio show.

Mickey's friends throw him a surprise birthday party at Minnie's house. The chef brings out the cake (with 2 candles); Mickey manages to blow all the cake onto the chef's face, while the candles stay lit. He unwraps his present: a miniature piano. He plays a duet of I Can't Give You Anything But Love, Baby with Minnie, followed by an instrumental version of The Darktown Strutter's Ball, which everyone dances to (including Mickey and Minnie, while the piano stools keep playing). Mickey then plays There's No Place Like Home on the xylophone, then accompanies Minnie on another piece, after which the xylophone gets frisky and eventually dumps Mickey in the fish bowl.

Mickey Mouse is about to build Pluto a doghouse when Pluto digs up a magic lamp that speaks in African-American vernacular. It offers to do Mickey's bidding. Mickey's first wish is for a doghouse, and the lamp starts to work. Suddenly, the saw, the planer, the paintbrush and other tools magically begin working on their own. Finally, Pluto has a magnificent doghouse. The second wish? Mickey asks the lamp to give Pluto a bath. But things go awry when Pluto accidentally breaks Mickey's radio. Now, all sorts of conflicting messages are coming out of the speaker as Mickey tries to fix it. The lamp assumes all the voices are Mickey's and obeys them. Pluto is rolled with a rolling pin, punched with boxing gloves, frozen in an aspic and is about to be cut into thin slices before all ends happily.

Mickey and Donald take a truckload of mouse boys on a picnic. The boys delight in tormenting Donald, first by filching the picnic food, then giving him a flower with a bee inside (Donald eventually gets the whole hive after him), and finally a sandwich with another bee in it.

Minnie is baking cookies. When she leaves for a short while, her dog Fifi accidentally drops popcorn kernels in the dough. Mickey and Pluto come over and visit with Minnie and Fifi. When Mickey notices that something is burning, Minnie remembers the cookies, which are popping popcorn out of them. Minnie is upset and lies on her sofa crying. Mickey goes out and buys a large amount of cookies and crackers. He comes back and shows them to her and she is overjoyed. The short was originally a theatrical advertisement for the National Biscuit Company (now known as Nabisco), where all of the products seen are various Nabisco products (i.e. Ritz Crackers, Oreo Cookies, Fig Newtons, etc.). These would later be edited out and replaced with generic-brands in television broadcasts and home video releases.

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.

Minnie rides into town and takes a large sack of money out of the bank. Pegleg Pete gathers his gang to take it from her, and they chase her out of town. Lonesome cowboy Mickey, who met Minnie earlier and was told she could take care of herself, sees this chase unfolding from his high perch, and rides down to save the day.

Mickey and Minnie are next-door neighbors tending their yards. When Minnie is captured by a bird's song, Mickey hides in his bird-house and pretends to be a bird himself, until a cat attacks and blows his cover. Then he does a dance while wearing the house; their song attracts more birds, and again the cat. Pluto chases, but he's still pulling the lawnmower, and it causes much destruction.

At Christmas time, Mickey Mouse, Minnie and Pluto are beset by an enormous litter of bratty orphan cats.

Even though Mickey's evening started slow and lazy, things get moving in a hurry when Minnie calls from outside the big dance, wondering why he's late. Luckily his best pal Pluto is happy to help wrangle the uncooperative evening wear and help get him out the door...without the tickets
