List of implied species
A list of implied species that have not physically appeared in any form of media up to this point in time. Regardless of their lack of appearances, the implied species have been mentioned at least once throughout the Mario franchise.
The Ancient Stickerish people are mentioned in Paper Mario: Sticker Star. In the Enigmansion, one text on a bookshelf reads "PAPERABBLESTICKEROBBLE DERRSTICKER STICKARONISTICK PAPERDAPERDOOPER STICKITYSTICKITYSTICKITY PAPEROOSKI PAPERDOODLE STICKERPAPERRAWK." Kersti claims to have not studied Ancient Stickerish since high school, and flunked her Ancient Stickerish class. However, she manages to translate it as "an ancient prophecy that fell from the Sticker Comet" that reads "The five lights...then the truth shall be revealed!"
As Hamma Jamma tells Mario, dropping out of Hammer Bros. school to go to Business Bros. school (as his father did) is a responsible (yet, according to him, lame) act.
The Luffs once made up a great kingdom. Their tale is told in Paper Mario: The Thousand-Year Door, and, although they are never seen, they are integral to the deeper parts of Luigi's Paper Mario: The Thousand-Year Door adventure.
The Luffs were responsible for the forging of the Marvelous Compass, and they used its powers to take over the majority of the world. However, since the Luffs misused it, the compass cursed them, destroying their empire. Hoping that this would not happen to other kingdoms, a Luff boy named Cranberry broke the Marvelous Compass into seven parts, hiding six and keeping one with him in Rapturous Ruins. After a thousand years of sleep, Cranberry would become the last of the Luffs, and even he disappeared when awoken by Luigi, who intended to rebuild the Marvelous Compass.
The Luffs' part in Luigi's story was not yet over, however. After making it to Hatesong Tower, Luigi would soon hear the true intention of Minister Crepe: He had apparently always been planning to usurp the Marvelous Compass from Luigi's hands and reestablish the Luff Kingdom as his own. Luigi would not comply, and Crepe was soon defeated.
