Boo Buster Luigi

Get out of Yoshi's body, you kingly pain in the butt!" Luigi hissed.
Yoshi (or rather, King Boo inside Yoshi's body) laughed. "Defeat me, and you'll be sure to get him back." The possessed Yoshi leveled an evil look at the green plumber. "But I wonder...can you defeat your own friend in the process?"
