The gang is on vacation. Goofy has some surfing problems, Donald learns why you don't wear a grass skirt near a fire, Pluto and a starfish have a tiff, followed by an encounter with a hermit crab.
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?
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. Pete secretly wants to get rid of the queen, so he appoints Mickey and his bumbling friends as guardians to Minnie, thinking such a maneuver will ensure his scheme's success. The score features songs based on familiar classical melodies.
Mickey leads his polo team Donald (on a mule), Goofy, The Big Bad Wolf against an all-star team: Stan Laurel, Oliver Hardy, Harpo Marx (on an ostrich), Charles Chaplin, in a game refereed by Jack Holt. Featured spectators include the Three Little Pigs with Shirley Temple, W.C. Fields, and Clarabelle Cow with Clark Gable. Game action proceeds pretty much as you might expect from this bunch of comedians.
Mickey shows off his ice-skating skills to Minnie; Goofy does some unconventional ice fishing; Donald straps skates to Pluto and laughs at his attempts to skate. Donald gets strapped to a kite and is about to be swept over a waterfall when Mickey pulls off an heroic rescue.
Mickey guest-directs a radio orchestra. The sponsor loves the rehearsal, but come the actual performance, Goofy drops all the instruments under an elevator, so they sound like toys. The sponsor hates it, but the audience loves it anyway.
Mickey and friends put on a revue for the orphans. Donald recites nursery rhymes, but the orphans torment him. Horace, Goofy, and Clarabelle do a dance number. Donald tries again. Clara clucks a song while Mickey plays piano (with support from an unseen orchestra). Donald returns, and the orphans finally send a parade of bricks and eggs on balloons over him and use slingshots to drop them on his head.
Donald and Mickey are overdue on their rent, so the sheriff is preparing to evict them and sell their belongings. Goofy the ice-man comes by and helps them move out before the sale, but their piano doesn't want to stay on his truck. Meanwhile, Donald has a fight with a plunger and a fishbowl after removing a heater from the gas line.
