Giantland
Mickey’s orphans ask for a story; Mickey casts himself as Jack in Jack and the Beanstalk. He starts with the climbing of the beanstalk; after evading the giant a few times, he ends up inside a cheese sandwich, and then in the giant’s mouth, where he ultimately grabs onto a pipe and gets pulled out by the giant. In the ensuing chase, Mickey launches a pepper bomb to slow the giant down, then outruns him coming down the beanstalk and sets the stalk on fire.
Mickey telling the orphans a Jack and the Beanstalk story with himself as the hero — a version of the same tale the studio would return to properly, and at far greater expense, in Mickey and the Beanstalk fourteen years later. Watching the two together is a good short course in how much the studio's craft changed in between.
