Special Note to PopularMMOs:
Hey guys, I made a special thing for you in my map! Download it to find out! You make the best videos, and I even made some of this map while watching your vids! Always stay awesome!

Note to Nintendo (or any other companies that might sue me):
I do not own any characters, stages, or concepts in this project. I just made this for fun, and I would really appreciate it if you don't take this down. Repeat, I do not own any characters, stages, or concepts. Thank you.
