Goldbob Guide

Goldbob's Guide is an item found in Paper Mario: The Thousand-Year Door. In order to use the cannon in Fahr Outpost, Mario must have permission from Goldbob and General White. If Mario confirms he will give every coin he has for Goldbob's permission (Mario won't have to actually pay), Goldbob will give it to Mario as a sign of approval. It apparently contains instructions for the Bob-omb Cannon.
