The gang throws Mickey a surprise birthday party; his present is an electric organ, which Minnie plays while Mickey does a jazzy dance. Goofy bakes the cake, but keeps having trouble with it falling. The gang does a conga line to a Latin tune.
In Disney's take on the Alexander Dumas tale, Mickey Mouse, Donald Duck and Goofy want nothing more than to perform brave deeds on behalf of their queen (Minnie Mouse), but they're stymied by the head Musketeer, Pete.
Mad scientist Mickey has just brewed up a potion; to test it out, he squirts it on a fly that's been trapped by a spider, a (regular) mouse being harassed by a cat, then the cat when Pluto goes after it, and Pluto when dogcatcher Pegleg Pete goes after him.
Based on the timeless adventures of "Jack and the Beanstalk," Mickey, Donald and Goofy climb a fantastic beanstalk up into the sky to a place where everything is huge -- the food, the castle and the fearsome giant named Willy who guards a beautiful golden harp! Will Mickey and his friends outwit the giant and make it safely back home?
The two pigs building houses of hay and sticks scoff at their brother, building the brick house. But when the wolf comes around and blows their houses down (after trickery like dressing as a foundling sheep fails), they run to their brother's house.
Chased by Tom around the barnyard, Jerry takes refuge under a huge, rather mean-tempered hen (which looks suspiciously like a rooster), who is sitting on eggs (which she puts in order with a billiard triangle!).
