Nabiru mask.I loved the cat mask (I believe that is MH) that meowed when you put it on. I don't know who he is, but the sound was hilarious.
I liked a lot of the fortune teller cookie stuff. But part of me feels like the Mario series stuff is going to be lame. Like a red sofa with a big white circle/M in the middle of it. Or a red table with the M in the middle. I can see them giving us 'realistic' furniture instead of giving us whackyzany furniture like a turtle shell that makes a SE when you interact with it.
I've only played a MH demo and didn't like it, but loved all of Felyne's RV items.
