Newsletter...

Newsletter... is the seventeenth Trouble Center mission in Paper Mario: The Thousand-Year Door, initiated by Mayor Dour. It is first available after clearing Chapter 4.

Mission
Mario must head to Mayor Dour's house in Twilight Town, and he gives Mario the Routing Slip to deliver to the Puni elder in The Great Tree. Upon delivery, the elder asks Mario to deliver the Routing Slip to Mayor Kroop in Petalburg due to having a hernia. After this second delivery, Kroop asks Mario to deliver the Routing Slip back to Dour due to having a cold. Following this third delivery, Dour thankfully rewards Mario with thirty coins, and the trouble is solved.
