Nooper

The name of the level that started internal jokes, a rebirth, an X version, and a collab in Geometry Dash, thanks to a joke that a youtube streamer made.
The level has horrible gameplay and horrible decoration, but actually was liked because of it.

-Remember Nooper? that level that was so terrible, that a group of people made a top tier demon out of it?
+Yes, how couldn't i?

-This level is better than Nooper
