Yes I don't like the idea of Rosalina and Waluigi as a couple either

even if suggested that.
and this whit Rosalina is Peach daughter. I don't know if it is true I have read that here??
(http://www.gamespot.com/forums/topic/26380509) Is only a rumor...
Peach and Daisy were also quite similar before the change Daisy.
She had long hair before as Peach has. And Peach was brunette before the change her to blond.
so do they change Daisy because she was like Peach when she was a brunette..
I love Peach

and will always do!
But like Daisy too

but when the change Daisy after MP3 I was sad because she reminded me of Peach as Brunette

.
But think Nintendo did the right thing to change, so you know that Peach and Daisy are different..
But this is my theory and could be wrong
But I would really like Rosalina to be in MP9
I have never liked Donkey Kong! but do not like Waluigi either so.
But they belong to Mario Team. to remove them is wrong. and you do not need to play as them you do not like.. ;D
