Super Mario series

Super Mario Galaxy

In Super Mario Galaxy, in order to become Boo Mario, Mario must grab a Boo Mushroom. With this transformation, Mario can turn himself invisible and pass through certain walls and gates by shaking the Wii Remote, levitate by pressing the A button, and descend by holding Z. The walls Mario can pass through as Boo Mario are similar to the ones he can pass through with Vanish Cap in Super Mario 64. Mario can also understand the language of the Boos, called Booish, meaning signs written in that language can be understood by him once he transforms. His Boo form also attracts other Boos, causing them to follow him around and allow him to make use of them for various purposes. The transformation is lost if Mario takes damage, passes through light, touches water, or touches a Launch Star.

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. It is also used in Boo's Boneyard Galaxy and Sand Spiral Galaxy.

This power-up returns in Super Mario Galaxy 2, in the mission "Haunting the Howling Tower" of Boo Moon Galaxy, where the power-up is very widely used.

Are you afraid of ghosts? Maybe it will help to see the world as they do. Become Boo Mario with a Boo Mushroom, and then explore their world! Shake your Wii Remote to make Boo Mario go through walls. Boo Mario blends in OK, but even as a ghost he keeps his trademark hat. The other Boos don't seem to mind, thankfully. Boos are always tricky to deal with, so if you can't beat 'em, join 'em! All you need to do is grab a Boo Mushroom, and you'll become a Boo, letting you turn invisible, slip straight through walls and even speak Booish! You'd think Boos wouldn't fall for it, what with that trademark cap still firmly on top of your head...but luckily, they do.
