In Paper Mario: The Thousand Year Door you can find a building in East Rogueport called the Trouble Center. The building lets you take on quests known as "troubles" for the citizens of Rogueport and the surrounding areas. Once you accept a trouble you must complete it or pay to dismiss it before choosing another. New troubles will become available at the end of each chapter. There are rewards for completing each trouble, but there is no final reward for completing every trouble in the game.
Note: this guide is currently under construction.
Post Prologue Trouble Center Quests
Need a Key!
You'll need to find a key for Garf, who is standing in front of his locked house to the east of the Trouble Center. Head to central Rogueport and go to the second floor of the Inn. Head through the door here to find the key on the ledge. Head back to Garf and return the key and you'll receive 30 coins as a prize.
Safe delivery...
You can find McGoomba on the right side of the alley behind Rogueport Plaza. He'll give you a box to deliver to Goomfrey, who is in front of Professor Frankly's house in Rogueport East. After doing so speak to McGoomba again and you'll get a reward of 30 coins.
Competitor research!
Arfur, who can be found standing in front of the Trouble Center after accepting the quest, needs to know the prices of Fire Flowers (10 coins), Sleepy Sheep (8 coins), and Tasty Tonics (3 coins) from the shop in Rogueport Plaza. After reporting the prices you'll get a reward of 30 coins.
Find this guy!
Goomther needs held locating the guy who committed credit card fraud against him. You can find Goomther on the west side of Rogueport Square. You can find the bandit (Larson) by going behind the fake wall as soon as you enter East Rogueport. When you confront him, he'll run off to Rogueport Harbor.
Head to the harbor and you'll find Larson hiding to the left of the staircase. Confront him again and he'll run off to the alley behind Rogueport Plaza. Go find him on the left side of the alley and he'll stay put long enough for Goomther to come over and give you your 30 coins as a reward. Goomther then delivers a beating for your enjoyment.
Hit me, please!
Mousimilian can be found in front of the shop in Rogueport Square. All you have to do in this quest is whack them with your hammer until they remember a slick money making trick. Your reward for this quest is the knowledge of that trick: you can buy Sleepy Sheep from Rogueport and sell them in Petalburg for a 2 coin profit.
I'm hungry!
You can find Bomberto in Rogueport Harbor near the docks. Speak to him and he'll ask for something to eat. You can feed him a Mushroom to satisfy the quest. He'll then reward you with 11 coins.

Try to find me!
Koopok is a hide-and-seek champion who wants you to find him somewhere in Hooktail Castle. Go there and navigate all the way to the room on the second floor with the large green block that serves as an elevator. Ride the green block up to the top and then you can drop down onto the ledge to the left to find Koopok. As a reward you'll get the Special Card.
Listen to me!
Mayor Kroop just wants someone to listen to him. Make your way over to Petalburg and speak to him in his pink house. He'll give you a rambling story about the youth of today and young love. You'll get a Turtley Leaf as a reward. While you are in Petalburg, it is strongly recommended that you buy 5 Courage Shells from the shop if you are planning on doing the next quest. This will save you a trip back to Petalburg.
Help me restock!
Visit the shop in Rogueport Square and speak to Plenn T. He requests you to bring him 5 Courage Shells. If you don't already have them, you'll need to go buy them from the shop in Petalburg. Once you deliver them you'll get a Ultra Shroom as a reward.
Post Chapter 2 Trouble Center Quests
Life Mushroom!
To complete this quest you'll need to bring the Puni Elder a Life Mushroom. He can be found in the first room of the Great Tree. You can use the new warp pipe to get very close. If you don't have a Life Mushroom, you can buy one from the shop in West Rogueport. You'll get 50 coins as a reward.
Come over and play!
For this quest, Lahla the Boo wants you come play some games at the Pianta Parlor in West Rogueport. All you need to do is go speak to her at the desk and she'll give you 10 pianta tokens.
Help my Daddy!
Pine T. Jr. says his daddy is missing in the Pit of 100 Trials and needs you to rescue him. In order to do so you'll need to make your way down to Level 18 of the pit, defeating all the enemies along the way. When you get to Level 18 you will find Pine T. Sr. lying on the ground. After defeating the enemies on this level, speak to him and he'll ask you to show him the way out.
You'll need to continue down to Level 20 before you are able to exit with him. When you reach that level he will automatically exit and you can choose to keep going or not. Use the exit pipe to go back to the top of the pit where you can speak to Pine T. Jr. & Sr. As a reward you will the Silver Card, which lets you play the Paper Mode game in Pianta Parlor.
Post Chapter 3 Trouble Center Quests
Help wanted!
Jolene needs some help cleaning in the Glitz Pit. Use the warp pipe to get to Glitzville and head to the promoter's office, which used to be Grubba's office. If this is your first time entering since your fight, Jolene will first sign you up to be a fighter again, starting over back in the minor leagues. Speak to her again to take on her request.
She wants you to clear out the garbage in the storage room, which is one door to the left in this hallway. Inside you'll find a bunch of dirty laundry. You'll have to make use of Yoshi's flutter jump to reach them all on the scond floor. When you've picked up all the Battle Trunks return to Jolene and she tells you to get rid of them by pawning them off on Goomfrey in Rogueport.
You can find Goomfrey in East Rogueport. After handing over each pair of Battle Trunks one by one he tells you to get your reward from Jolene. Head back to her office and you'll be rewarded with 30 coins. More importantly, doing this quest unlocks the ability to fight the former champ Prince Mush in the Glitz Pit later on. He'll send you an email when he's ready to fight. While you are in Glitzville, it's a good idea to buy two Hot Dogs for a later quest.
Heartful Cake recipe...
Speak to Merlee in sublevel one of Rogueport Sewers. You can take the East Rogueport pipe and take the second pipe to the right to enter the background to enter Merlee's hut. Speak to her and she'll ask you to get the Heartful Cake recipe from Toce T. in Petalburg. Take the warp pipe there and enter the eastern most house. Toce T. will give you the recipe which is a Cake Mix and a Ruin Powder.
Head back to Rogueport and purchase a Cake Mix for 6 piantas at the Pianta Parlor if you don't already have one. It's a good idea to pick up a second one for the next quest as well. Head back to Merlee in the sewers to give her the recipe and Cake Mix. She'll give you 30 coins as a reward.
The food I want.
Bub-ulber from Petalburg wants you to bring him a variety of food. To save several back and forth trips you can prepare this food ahead of time. If you don't already have them, you'll want to go buy two Hot Dogs from Glitzville. You'll also want to bring Zess T. a Cake Mix (you can get one as a reward from Pianta Parlor) to bake into a Mousse Cake.
Take the warp pipe to Petalburg and speak to Bub-ulber on the west side of town. Deliver each of the food items he requests one by one. After you do he will reward you with a Dried Bouquet. These are pretty terrible on their own, but they can be cooked with various other ingredients to create powerful healing items. You can get more by trading Bub-ulber a Hot Dog.
