Paper Mario 2 is the sequel to Paper Mario. After 40 years, George W. Bush finally comes out of the bathroom after taking a real long crappy crap, and gets mad because the Mario's escaped. Bush goes on a rampage, and destroys the city. The Mario's, now in YEE-YAW TEXAS, heard about it and knew it was their destiny to rescue the city.

The Final boss is Giant stick-man. At the end of the game, the Mario's all get squished and die. Rest in Pain, Maria.

This game had a sequel, Paper Mario 3.
