...Luma?

Luma? Where you go? D;
Pay attention Rosalina; this is your first time participating in Mario Kart!

I was playing Mario Kart Wii, and Rosalina got hit by a Bullet-Bill, thus giving me this idea.
How can Luma manage staying by her side the entire time throughout the game?
((Well, yeah the game was programed that way, but you should know what I mean.))
