I've found a vid of rosalina:
YouTube - Mario Kart Wii - Rosalina Gameplay (Online)
Ha ha... I like the way one of those luma thingys float beside her.
It points which way she's turning.
here's king boo on his bike:

notice when he does sharp turns he holds out his arm... thats what the luma does for rosalina
