I need help I can't find goldbob and general white please help.?

Goldbob is the one you saved on the train he lives in the town that the train goes to I forgot the name. And for the other guy just folow what people say after you find goldbob. (right after you find goldbob and get permision to use the cannon go straight back to the town and talk to the guy by the cannon statue.)
Hope I helped

Goldbob makes his residence in Poshley Heights. Rather than take the train, you can return there via a warp pipe in the area beneath Rogueport. You'll find Goldbob in front of the blue house on the west side of town. When he asks how much you're willing to pay to use the cannon, answer "Everything I have!" then answer "Yes" to all of his subsequent questions. He won't actually keep your coins, but he will give you the Goldbob Guide. General White is a bit more difficult to track down. You may remember seeing him in Petalburg. Head there from the blue warp pipe beneat Rogueport and talk to the Koopa near the west entrance. He'll point you to Keelhaul Key, so head to the shanytown and ask Pa-Patch for another clue. Return to Rogueport and take the blimp to Glitzville. If you inquire with the juice-shop owner as to General White's whereabouts, he'll recall something about a big tree. That means the next stop on your whirlwind tour is Boggly Woods. The first Puni inside the Great Tree will tell you that White went somewhere dark. Make your way back to Twilight Town and talk to the villager standing in front of the inn. It seems General White isn't there anymore (surprise!), so drag your dejected self back to Fahr Outpost. While you're reporting to the mayor that you haven't been able to find White, you'll see the general step out of the house in the background! Follow the elusive Bob-omb back inside and wake him up (you'll have to give it several tries).
