I give this a short film a 7, not because I think its worth watching by today's standards, just in comparison to all of the other 1930-40s anime that I've seen. Anime from this era are silent and all black and white. Many of them were poorly preserved, but this one looks ok. Its basically created to teach a moral lesson, as you would expect anime of this time to do. The story is about crabs who are taken advantage of by a monkey. It teaches that its ok to share with some people, as the crabs did with the bees, but there are somepeople who will take advantage of you. Its actually a pretty cute animation, and if you want to try 1939 anime this may be a good starting point considering its not confusing war propaganda and its also fairly well preserved over the years.
