As part of the progressive unlocking system that Super Mario Maker uses, this is heavily based on the tracks pack that you get. Incidentally, I made the stage when I obtained the pack. There is a mandatory side quest in this stage that prevents you from passing the stage if not completed. It may seem a bit puzzling if you hadn’t watched this video beforehand, so it’s important to be creative.

If you want to try it out for yourself, the code is:
