Gustafa

Gustafa is the leader of the Undesirables, a group of eccentrics who live in the Southwest Quadrant of Forget-Me-Not Valley. While he has a proclivity towards peace, he eventually commands the Undesirables to help Muffy Fuller proclaim herself Mayor of Mineral Town, but are immediately defeated by Jon Takakura and Marlin Stanton. Eventually, he would join Marlin in his attempt to make himself Mayor of the Pass.

Game of Towns
Relaxed and carefree, Gustafa is not concerned with the Game of Towns.

Heir By Iron
Again, Gustafa stays out of the War of Town and Valley and the Undesirables do not get involved. In the end, however, they ally with Muffy to make her Mayor.

War for Winter
Gustafa loses the battle to Jon Takakura and is jailed with the rest of the Undesirables at the Falls. Eventually, he agrees to help Marlin become Mayor of the Pass and is freed. When Takakura gives chase to Marlin, they flee to the Highlands. Most of the Undesirables who follow Marlin to the Highlands are eventually killed by the Mukumukus, and eventually only Marlin and Gustafa are left. Gustafa tries to kill Marlin in revenge but Marlin kicks him off. The two fall into what they realize is the Stanton Graveyard. They are bitten by the fleas and Gustafa does not try to kill Marlin, knowing that both of them are doomed to death. Marlin leaves the Graveyard to tell Harris about the Sickness as a way to defeat the Mukumukus. Gustafa stays in the Graveyard, dying.
