Orange Potion

The Orange Potion is an important item found only in Paper Mario: The Thousand-Year Door. The Orange Potion is a chemical created by X-Naut chemical technicians for unknown purposes.

During one of the chapter intermissions, Princess Peach had to use this potion — along with the blue, green, and red ones — in order to make herself turn invisible. With the help of TEC-XX, she successfully did so, and was then able to secretly infiltrate Sir Grodus' office and steal the Data Disk that TEC-XX requested.
