Trivia
Boo Mario races the Spooky Speedster in Super Mario Galaxy.Boo Mario is a form of Mario that appears in the game Super Mario Galaxy. As its name implies, the Boo Mario form is Mario disguised as a Boo, although his hat and face remain relatively to his normal form. Boo Luigi in Super Mario Galaxy 2.In order to become Boo Mario, Mario must grab a Boo Mushroom. With this transformation, Mario can turn himself invisible and pass through certain solid walls by shaking the Wii Remote, and levitate by pressing the button. Mario can attract Boos as well, and use them for various purposes. The transformation is lost if Mario takes damage, passes through light or touches water. Mario first uses this transformation in the Ghostly Galaxy to rescue Luigi. Because Luigi is afraid of ghosts, he cowers when Mario approaches him in Boo form; therefore, Mario must return to his normal form beforehand. Strangely, if Luigi plays through this level he has to rescue himself as Boo Luigi. This power-up does appear in Super Mario Galaxy 2, but in only one galaxy: the Boo Moon Galaxy in the mission "Haunting the Howling Tower".
