Important Thing!

Important Thing! is the twenty-first Trouble Center mission in Paper Mario: The Thousand-Year Door, initiated by Frankie. It is first available after clearing Chapter 6.

Mission
Mario must head to the west side of Rogueport to find Frankie next to a fountain. When talked to, Frankie tells Mario that he lost his Wedding Ring in Rogueport. In versions outside of Japan, the ring is found in front of Garf's house in the easternmost area of Rogueport. In the Japanese version, it is found on top of the wall guarded by Gus. He must then return the Ring to Frankie, who rewards him with a Gold Card, and the trouble is solved.

In-game description

 * "I'm lookin' for somethin'. I can't say exactly what here, but I can tell you in person. I'm waitin' on da west side of Rogueport."

Trivia

 * In the Japanese version, if Frankie's trouble is cancelled before Mario collects the wedding ring, the ring will not despawn. If another trouble is taken and then the ring is collected, the ring will set a flag that is used by other troubles. This allows some troubles to be progressed simply by collecting the ring.
