Lineland

Lineland is the setting of Chapter 1-1 in Super Paper Mario. This land is a grassy plain populated with Goombas, Koopa Troopas, Squigglets, and Sproing-Oings. It is also home to Bestovious, the wizard that teaches Mario how to flip.

It may also be noted that part of Lineland is a recreation of World 1-1 of Super Mario Bros..
