Elusive Badge!

Elusive Badge! is the sixteenth Trouble Center mission in Paper Mario: The Thousand-Year Door, initiated by Ms. Mowz (identified as ??? in the Trouble Center). It is first available after clearing Chapter 4.

Mission
Mario must head to the rooftop of Zess T.'s house in Rogueport Square, where he meets Ms. Mowz, who will tell Mario of an "elusive" badge in Hooktail Castle. Mario must head to the castle, make his way to Hooktail's lair (where he defeated Hooktail earlier), and use Flurrie's ability at the center of the lair to reveal the Attack FX B badge. Mario then must bring the badge to Ms. Mowz, who reveals that she had hidden the badge herself to see if Mario can find a badge she had hidden so well. Ms. Mowz will join Mario's party, and the trouble is solved. The badge cannot be found in Hooktail's lair before taking on Ms. Mowz's trouble.
