Mousimilian would commonly smell Mario and tell him about his various of scents whenever he completes a Chapter. Mousimilian also has a trouble that involves hitting him many times until he remembers what he had to do. After hitting him enough times, Mousimilian will remember that he can buy a Sleepy Sheep at the nearby Item Shop and sell it to the one in Petalburg for a 2-coin profit. Although Mousimilian doesn't really reward Mario for helping him out, one can use Mousimilian's plan to make a profit each time themselves.
- Mousimilian's name is a combination of "mouse" and "Maximilian".
