Thriff T. (Minor Role for now)

Thriff T. is a Toad merchant from Paper Mario: The Thousand-Year Door. His name is pun on the word "thrifty", which means to spend wisely. He is the younger brother of Plenn T. who manages the Item-Shop of Rogueport. Though Thriff T. and his brother get along well, he dreams to open his own shop someday. When Thriff T. gets wind of Mario's ambitions to sail to Keelhaul Key, he immediately joins his crew because he sees his big chance in this. After the Crew's ship gets attacked by Embers and its passengers are trapped on Keelhaul Key, Thriff T. indeed gets his own shop, though it is just a tentative one made from debris. He decides to stay on Keelhaul Key even after Mario defeats Cortez, implying that he finally grew a liking to the deserted island and is willing to make a life there. The fifth issue of the Rogueport Direct Mail Service talks about his shop. According to it, Thriff T. opened up his shop there because he dreamed of doing something that had not been done before. He is also mentioned to be a former fighting fan. During the interview, he declares himself "the invincible shopmaster" and wants everyone to call him that.
