It's been a year since the case of my missing brother was solved - and things haven't gotten any easier. A vacation to a ritzy hotel with free food sounds great, right? ...Except a precious artifact has been stolen from Wario and we're all trapped here until someone can figure out who did it. It certainly won't be me, Luigi!

New Donk City. A tough place to live, and an even tougher place to do the right thing. Plumbing, detectiving... you still find yourself cleaning up other people's messes, and if you're not careful you end up in crap. It's all the same in the end. Without my brother around, things have only gotten worse. I need to find him.
