"Bro!" Luigi cried as he caught up with his older twin brother. "You ok?"

"Yeah," Mario said as they waited for the final boss battle in the Battle Medley to start. "I'd forgotten how powerful Antasma X could be. Fortunately, he threw that spinning circle often, so it was easy to dodge."

"Well, we're good now!" said Luigi happily as they checked their HP and BP. "We're in good health, and this secret boss can't be worse than Bowser X, right?"

Mario frowned as he remembered the close call they'd had with Bowser X in their previous adventure; Bowser X liked growing giant and chasing after the brothers often, forcing them to run away and jump over fireballs quite frequently.

"Uh, yeah, I guess."

"Oh, look!" Luigi exclaimed. "It's time to go!" With that, the brothers were warped to their final boss battle.
