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.

Tom's advances on a young jive-talking girl cat get nowhere; nowhere, that is, until Tom gets a zoot suit. Armed with his miles of fabric and a new cool lingo, Tom still has to deal with the tricks of his nemesis, Jerry.
Jerry runs into a dog pound (and right on top of a napping Spike) to escape a rather mangy-looking Tom. To avoid being ripped to shreds, Tom borrows the head of a nearby dog statue. This easily fools the dogs, but not Jerry, and Tom keeps losing his newfound head...

Jerry is awakened from a nightmare by a knock on the door: someone has left a foundling in a walnut shell with a note, giving his name as Nibbles and saying he needs lots of milk. Fortunately, there's a dish handy, but it's next to Tom. Nibbles scurries out and dives off Tom's nose, then grabs a whisker for balance, waking Tom up. Jerry grabs him just in time and they hide under the milk. Tom laps up some milk and gets Nibbles; Jerry rescues him, and they run for the hole. Next, they try a very long straw; Tom catches them and sucks Nibbles through the straw. Much chasing follows, with a pause now and then for some milk. Tom traps Jerry in a milk bottle and chases Nibbles a while; he finally corners Nibbles and spanks him with a flyswatter. Jerry is so enraged he burst out of the milk bottle and lets out a ferocious roar; he grabs Tom by the tail and thoroughly pummels him, then stands over him as Tom feeds Nibbles milk.
