Boo Mario is one of Mario's many forms. This form first appeared in Super Mario Galaxy in the Ghostly Galaxy. If Mario obtains a Boo Mushroom, he will turn into Boo Mario. Boo Mario can float by pressing the A button and turn himself invisible by spinning the Wii Remote, making Boo Mario go through solid walls. If he flies into a light, he turns into regular Mario.
