Well, you get what you see, if you've read the synopsis you're pretty much seen the short cause the only thing omitted from it is that the whole story is just a dream. It's easy to be harsh on something like this but as a short and amusing animation for kids made 80+ years ago it does what it sets out to do without wasting time. If anything it aged relatively well compared to some of the anime produced around WW2 cause it still moves smoothly and has comedic bits that I think most people will still find at least slightly amusing, in particular Norakurodeliberately deliberately breaking physics to achieve his goal. If you have some interest in anime before it became the way we know it this is worth checking out.
