Heartful Cake Recipe...

Heartful Cake Recipe... is the fourteenth Trouble Center mission in Paper Mario: The Thousand-Year Door, initiated by Merlee. It is first available after clearing Chapter 3.

Mission
Mario must first visit Merlee in Rogueport Sewers, who directs him to Toce T. in Petalburg. Mario must then travel to Petalburg and visit Toce T. in her house. When talked to, Toce T. informs that the ingredients for a Heartful Cake are Cake Mix and Ruin Powder, but wonders who Merlee is making the cake for. Mario must then return to Merlee and relay the information to her. She then asks Mario to bring her some Cake Mix. Mario can buy a Cake Mix from Pianta Parlor in Rogueport's west side. After Mario gives Merlee the Cake Mix, she thankfully rewards him with thirty coins for solving her trouble. If Mario brings a finished Heartful Cake to Merlee for this mission, she will not accept it.
