This is the Super Paper Mario: 2 Button Challenge. The goal of the challenge is to beat Super Paper Mario while pressing the "2 button" as few times as possible. "Beating" Super Paper Mario requires Mario and the other characters to reach the end credits. Any method is allowed.

What does the "2 button" do?
The "2 button" does all of the following:
-Jump
-Swim
-Answer a multiple-choice prompt
-Open the quick menu
-Select any item in a menu
-Enter passwords
-Shoot with Squirps

Things that look like they need the "2 button" but can be accomplished with other buttons:
-Progress through dialogue ("1 Button")
-Selecting objects with Tippi ("A Button")
-Ground pounding with Thudley ("1 Button")
-Exiting free fall as Luigi ("1 Button")
