1.9)- Worlds, Chapters, and Levels.

Understand how Worlds, Chapters, and Levels are used interchangeably in Paper Mario, referring to the same game segments like World 1-1.

Within the game itself, these segments are officially called "Chapters." However, many players commonly refer to them as "Worlds," drawing a parallel to the classic 2-D Mario games. The term "Level" is a more general video game reference.
