Goldbob is a Bob-omb who appears in Paper Mario: The Thousand-Year Door. He first appears in Glitzville outside of the Glitz Pit along with his wife Sylvia, and his son Bub. Goldbob soon becomes a fan of Mario/The Great Gonzales after his position in the ranks of the Glitz Pit moves up.
Goldbob appears again aboard the Excess Express on his way to Poshley Heights. After the trip he and his family will remain in Poshley Heights.
Later Mario and his team must search Goldbob out to get his permission to use the cannon in Fahr Outpost.
In the game, he appears on the Trouble Center, asking Mario to send a package to General White. If you complete this quest, he will give you 64 coins (possibly a reference to the Nintendo 64).

That's Goldbob the Bob-omb. He's head of a wealthy buisiness, Goldbobbington's. He's got buckets of ducats, they say. I guess some folks are just good with money!
