Mousimilian (Minor Role for now)

Mousimilian is a Little Mouser in Paper Mario: The Thousand-Year Door. His name is a portmanteau of "mouse" and the masculine name "Maximilian". He hangs out in the Rogueport plaza, in front of the Toad Bros. Bazaar. He smells propositions that may make him loot. He also makes a comment about Mario's scent every time the player speaks to Mousimilian. The scent he smells is usually reminiscent to a certain event that happened to Mario during the last chapter he visited.

Mousimilian also has a trouble. When Mario takes on his trouble, Mousimilian tells Mario that he learned a new money-making scheme, but forgot it. He wants Mario to hit him with his hammer repeatedly until he remembers it. It takes 10 times to do the job. The scheme is to buy Sleepy Sheep in the Toad Bros. Bazaar and sell it in Niff T.'s shop for a profit of two coins, which he tells Mario as the reward for helping him.
