Bowser's Star Reactor

Bowser's Star Reactor is a place located in Bowser's galaxy from the upcoming game Super Mario Galaxy. This is the third Grand Star location. Mario will first make his way to Bowser, who appears and shoots fireballs at the plumber. After Bowser is defeated, he will say that it isn't over yet and disappears. Then, a Grand Star will show itself to Mario. This speech is the same thing he says in super mario 64.
