Mop it up is right. It's like she could be a mod here or something. Everyone has a username to their account which is the name they put it when signing up. That said, the forum has another slot called Name which is what everyone else on the forum can see as your identity. That name slot can be changed to create a different name to be displayed on the forum like I've been doing with Zap (should give him a new name now that I think about it) or during Khushrenada Week. It's how Lucariofan99 became Lucario. That said, the actual username cannot be changed. That is ultimately where all your posts are tied to and how your account was created. If you want to change the username, you'd have to start a new account. So, that's why you've still got to sign in with underscores but they can be removed for your name being displayed across the forums.
But we are missing the main point and that is the fact that Fatty the Hutt is safe! Everyone loves that Amiibo festival title.
With Fatty safe, that means the next person to choose is Insanolord. The remaining choices are:
Captain Toad: Treasure Tracker
Donkey Kong Country: Tropical Freeze
Mario Kart 8
Splatoon
StarFox Zero
Super Smash Bros. Wii U
Tokyo Mirage Sessions
Xenoblade Chronicles X
Yoshi's Woolly World
