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 Super Mario series.

Burpin' beetle
Burpin' beetles are a species referenced by Grubba in Paper Mario: The Thousand-Year Door. Mario and his party were spying on Grubba through the air vent above his office. Discussing what they heard, Grubba cried out, fearful that he had been heard. The player was given the options to make a squeak, meow, or burp. Should the player chose the third option, Grubba would be relieved, believing that he had overheard a burpin' beetle in his air vent rather than a person.

It is possible that burpin' beetle's aren't a distinct species, and that Grubba simply meant he had heard a beetle with flatulence. Additionally, based on Grubba's accent and speech patterns, the proper name for the species could be "burping beetle."

Business Bro.
Business Bros. are a type of Hammer Bro. whose existence is only implied in Paper Mario: The Thousand-Year Door. The only known Business Bro. is Hamma Jamma's father, although there are very likely several more.

Business Bros. seem to be the Hammer Bro. answer to the businessman. Therefore, it is assumed that Business Bros. lead a more laid back, controlled, and much less violent life in comparison to normal Hammer Bros. Also, as Hamma Jamma once told 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.

Donkey
Donkeys are a non-fictional species of animal referenced in Super Mario World 2: Yoshi's Island. When Baby Bowser first saw Yoshi, he asked whether he was a donkey and declared his desire to ride him as though he were one.

Mosquito
Mosquitoes are a non-fictional species of flying insects that suck the blood of larger organisms, such as humans, to feed their young. Humans often get "mosquito bites," or itchy, inflamed bumps. Luigi referenced them in The Super Mario Bros. Super Show! episode "Jungle Fever," implying their existence on either Earth or Mushroom World.

RecordoMeow
The RecordoMeows are implied creatures seemingly found in Fort Francis. They are only mentioned in Chapters 3-1 and 3-4 of Super Paper Mario; they are presumed to be PatrolMeow-style kitten robots that are known to record Francis' beloved television programs.

Sea turtles
Sea turtles were mentioned in the Super Mario Bros. film when Luigi was driving with Mario to a plumbing job. When Luigi made a right turn instead of a left based on his feelings, much to Mario's annoyance, he justified his decision by saying he had read that seas turtles navigate thousands of miles on instinct. Mario retorted that they did not do that in Brooklyn traffic.

Soybean Civilization
The Soybean Civilization, whose people have also been collectively referred to as the "Soybeans", was an ancient civilization that once inhabited the Beanbean Kingdom. Most of the Soybeans' past (and even their existence, which is only verified by the Beanstones and other remnants) is an enigma, and they were only hinted at in Mario & Luigi: Superstar Saga. Even hearing about the Soybean Civilization is completely optional for the Mario Bros., but they can do so by talking to Fava's brother (who describes himself as a great intellect) in Beanbean Castle Town, unless the town is under attack by Cackletta. If they do so, he will inform them that he is currently most interested in studying the Soybean Civilization and will ask Mario and Luigi if they wish to hear a report on it. If they answer "Yes", then he will begin speaking of the civilization, revealing much about it.

Apparently, the Soybean Civilization coexisted with (or possibly included) at least three Beanish subspecies: spin-beans (who had the ability of flight, likely a reference to the Spin Jump), mole-beans (who, like any other type of mole, could dig through the ground), and dash-beans (who could move at super speeds, hence their name). According to the intellect, the Soybeans may have also very well lived in the Beanbean Kingdom (or maybe even Beanbean Castle Town itself), although the only possible proof of this would be the location of the ten Beanstones, the civilization's buried treasures, in the town. The Mario Brothers could then accept the man's challenge of locating these underground gems, and he would finally reveal that the Soybeans were extremely short; as such, only Mario's crushed form could find the otherwise invisible Beanstones. (When the small Mario stood on one of the invisible pits in which the gems were placed, an exclamation point would appear above his head and, if Mario & Luigi: Superstar Saga was being played on a Game Boy Player, the GameCube controller would rumble.)

Afterwards, a Little Fungitown NPC would state that the lift platform from Teehee Valley to Little Fungitown was built by the people of the Soybean Civilization; interestingly, the design of this platform (which sported many fancy Mushrooms) may suggest that the Soybeans had some connection to the Toads. These were the only mentions of the great and ancient civilization, and, even when Mario and Luigi found the Beanstones and took them to Fava's aforementioned brother (who rewarded them with a Bros. Rock badge), he would only claim that he would announce his hypothesis on the civilization and take no further action in-game. Finally, it may be worth noting that, while references to the Soybean Civilization are rare in Mario & Luigi: Superstar Saga, the invisible pits in which the Beanstones are stored (as well as the strange reactions they trigger in short people) were actually spoken off in one of the many books belonging to a separate character in Beanbean Castle Town.

Trivia

 * The Soybeans' name simply comes from the soybean, a type of legume which is actually classified differently than the standard bean.
 * When Fava's brother talks about the Soybean Civilization, he refers to it as the less-proper "Soybean civilization"; however, the Little Fungitown character calls it the capitalized "Soybean Civilization".
 * When Mario's small form steps over a place where a Bean Fruit or Chuckle Bean is buried, he will once again get the same exclamation point over his head as if he was standing above a Beanstone; it is therefore possible that the Soybean Civilization is also responsible for burying some of the Beanbean Kingdom's other buried treasures.
