A Rubee is a fake, foreign currency used in Super Paper Mario. They play an important factor in escaping from Merlee's Mansion in Chapter 2-3. Mimi forces Mario to work in a sweatshop-like area until he can pay off his 1,000,000-Rubee Debt, or until he can buy the safe combination off a slave, with the safe holding 1,000,000 Rubees. She also throws them at Mario during boss battles to attack him.
- The word Rubee is a refrence to The Legend of Zelda in which the main currency used in the game is called a Rupee. Furthermore, It is colored red and resembles a Ruby thus creating the name Rubee.
