Security Code...

Security Code... is the twenty-fourth Trouble Center mission in Paper Mario: The Thousand-Year Door, initiated by the Businessman. It is first available after clearing Chapter 6.

Mission
Mario must head to Glitzville and talk to the Businessman, who tells him that he forgot the code to his briefcase, and the only way to remember it again is to count the number of chairs in Kroop's house first, Flurrie's house second, Don Pianta's office third, and Toodles's house fourth. Mario must then relay the code to the Businessman, 2625, which unlocks the briefcase. The grateful Businessman then rewards Mario with a Hot Sauce, and the trouble is solved.
