About Special Boo (Mario Ball Z)
The Special Boo looks like an Ordinary Boo but it isn't. The reason it is special because it can teach New Abilities, Skills, Transformation, and the most favorite is the Fusion Dance with the Boomoran Outfit if done the Fusion Dance.

Special Boo taught Mario the Fusion Dance and then Mario taught Luigi the Fusion Dance to Create the Legendary Warrior, Marluigi.
