Wandering Nomadimouse
From the Super Mario Wiki
A Wandering Nomadimouse.
The Wandering Nomadimouse is (obviously) a wandering Nomadimouse that resides on the path of the Dry Dry Desert. He appears in Paper Mario. To escape from the extreme heat, the Wandering Nomadimouse stays under the shade of a palm tree. A letter on a roof in Dry Dry Outpost is for the mouse. He'll give Mario a Star Piece if the plumber delivers the piece of mail to him.
