Proof
I can prove to you it exists! My uncle works at Nintendo, and told me everything about this stage, and even gave me a copy with it! Trust me! I would never lie to you, would I?

Theories
Why is there any theorizing to be done? My uncle promised that this is all the information about the level, meaning there is no need to theorize. Besides, if you thought I was lying, I would bet you are a Nintendo Ninja trying to silence my voice! Screw you Nintendo Ninjas!
