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 first head to the rooftop of Zess T.'s house in Rogueport Square, where he meets Ms. Mowz, who tells Mario of an "elusive" badge in Hooktail Castle. Mario must travel to the castle in Petal Meadows, 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 an Attack FX B badge. Afterward, Mario must return to Rogueport and present 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. She allows Mario to keep the badge, also joins his party, and the trouble is solved. The badge cannot be found in Hooktail's lair before taking on Ms. Mowz's trouble.
