I can't speak!

I can't speak! is the twenty-sixth Trouble Center mission in Paper Mario: The Thousand-Year Door, initiated by Gob. It is first available after clearing Chapter 7.

Mission
Mario must have a Honey Candy in his inventory. He will need Zess T. to mix a Honey Syrup with a Cake Mix (bought from Pianta Parlor) to make one. Then Mario must travel to Fahr Outpost and talk to Gob, who speaks weirdly. Mario can answer whether or not he understands what Gob is trying to say. Regardless, Mario must give Gob the Honey Candy, which restores his voice. With the trouble solved, Gob rewards Mario with twenty coins as a token of his appreciation.
