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 first head to the west side of Rogueport to find Frankie next to a fountain. When talking to Frankie, he informs that he lost his Wedding Ring in Rogueport. To recover the Ring, Mario must cross the stream near Garf's house with Mini-Yoshi. He must then return the Ring to Frankie, who rewards him with a Gold Card, and the trouble is solved.
