Linus is a villager who lives in a small tent north of Pelican Town near The Mines.

Linus generally considers himself an outcast of the town. He does not trust people, and doesn't seem to consider anyone in town his friend (However, based on dialogue only available using exploits, Linus is friends with the Wizard. This dialogue is accessible if the player talks to the Wizard who is overlooking the maze during the Halloween event.), as to the fact that most people don't treat him well. During Festivals, he can usually be found alone and out of the way. At one point, Linus tells the player that his tent has been destroyed before. Robin mentions that she doesn't mind him living behind their house, as long as he doesn't bother them.
