The next chapter of UME will certainly take around another week to make. The current week is a busy one for me, and part of the chapter is asking me to pass a lot of time in the wikis. As a result, it's very slow. So please, be patient.
On another note, I have also been using the time to think of other stuff for the future of the story. Especially about King K Rool. He is the only character of the Marioverse that hasn't appeared yet, and there's a good reason for it.
