List of implied locations
The List of Implied Locations is a list of place, kingdoms, and zones that have not physically appeared up in any form of media to this point in time. Regardless of their lack of appearance, the implied Locations have been mentioned at least once throughout the Mario series.
Banishement Zone
The Banishment Zone is a zone mentioned in The Adventures of Super Mario Bros. 3, where King Koopa was sent before the events of the cartoon. However, King Koopa escapes the Banishment Zone and returns to the Mushroom Kingdom again.
It is unknown how Mario, Luigi, Princess Toadstool and Toad sent King Koopa to the Banishment Zone. Supposedly, it was after the events of The Super Mario Bros. Super Show!. Nothing else is known about this mysterious zone.
Count Bleck's World
Count Bleck's World or Blumiere's World is a world that Count Bleck said he was going to create after destroying all worlds in Super Paper Mario. He said he would live with his minions, Mimi, Nastasia, O'Chunks and Dimentio happily but as it turned out near the end, he didn't mean it and he was actually going to destroy all worlds and not leave a single one. Not even his current one.
Dimentio said Count Bleck lied about the World and tries to convince Mario to join him to build perfect worlds, but Tippi alerted Mario he was lying and Dimentio starts to fight Mario.
At the end of the game, after Count Bleck (a.k.a Blumiere) and Tippi (a.k.a Lady Timpani) get married they go to some other world where they live happily ever after. After Mario and company all return to Flipside, Nastasia is sad that Count left and just can't stop crying.
O'Chunks and Mimi tell her that Count Bleck must be alive and in peace. They say that they will even build the world that Count Bleck wanted so much-a world with love not war. Though this world is never seen in the game, it is supposedly created after the events of the game and after the heroes return to Mushroom World.
Dry Dry Kingdom
The Dry Dry Kingdom is an ancient civilization that existed an unknown time ago in the Dry Dry Desert; Dry Dry Kingdom is mentioned in Paper Mario by a Dryite living in Dry Dry Outpost, as well as by other characters, though not by name.
The Dry Dry Kingdom was evidently a prosperous society ruled by a Nomadimouse named King Mousta; the subjects of King Mousta rose up against him and rebelled against his rule, wishing to have a society akin to anarchy, they exiling him from the Dry Dry Kingdom. King Mousta eventually struck back against his traitorous followers sometime after his empeachment, defeating them with those still loyal to him, thieves and bandits who would later go on to create the town of Dry Dry Outpost.
This war waged by the Dry Dry Kingdom's inhabitants and King Mousta may have caused the destruction of the Dry Dry Kingdom, or at least contributed to it. Currently, the only remains of the Dry Dry Kingdom's existance are the Dry Dry Ruins, which are guarded by Moustafa, a posible descendant of King Mousta or his second-in-command, a thief boss who was charged with guarding the ruins.
Flora Kingdom
The Flora Kingdom is an unseen part in Super Paper Mario. Not much is known about it, but Floro Sapiens are the residents and King Croacus IV is the current king of the kingdom. Thought it is not confirmed, the Floro Caverns might be under the Floro Kingdom since so many Floro Sapiens live here, and King Croacus has his room down there. The other kings of Floro Kingdom are King Croacus I, Queen Croacus II and King Croacus III. They all changed the Flora Kingdom somehow.
Frankenstein University
Frankenstein University is a school that was mentioned briefly on the bonus disc from The Adventures of Super Mario Bros. 3 The Complete Series DVD set. It is a school that Kooky von Koopa attended and graduated from. Nothing else is really known about Frankenstein University, although it is presumably a horror and/or mad scientist-themed school.
Koopergarten
Koopergarten is the supposed Koopa equivalent of kindergarten. Not much is known about Koopergarten, although the curriculum probably has to do with educating young Koopas so that they'll grow up to respect their own kind, and learn to despise the Mushroom Kingdom.
Koopergarten was only ever mentioned in Hip and Hop's biography from The Adventures of Super Mario Bros. 3 The Complete Series DVD set. According to the writers bible, the twins flunked Koopergarten.
Star Realm
The Star Realm is an area briefly mentioned in Mario & Luigi: Partners in Time. It is talked of by the gate in the Star Shrine when he commands Luigi to get the Aurora Block, something which is apparently very sought after (and even celebrated by) by the denizens of this mysterious place.
The Star Realm most likely includes the Star Shrine, and may or may not include Star Hill. Other star-themed areas not seen in Mario & Luigi: Partners in Time (such as the Star World and Star Road) could also make up the Star Realm, or it might be an individual area in itself.
Toadland Yard
Toadland Yard is an implied police headquarters given a few rare mentions in Mario Party Advance. As is with other implied things, little is known about Toadland Yard.
Toadland Yard is only heard of in the game's manual and Shroomlock's character list description in-game. These mentions respectively describe Shroomlock as "with" and "of" Toadland Yard, suggesting that he works for the organization.
These two mentions leave much to be learned about Toadland Yard. As a matter of fact, it is possible that Toadland Yard is not even a police group at all, but its namesake seems to confirm the fact that it is: Toadland Yard, in addition to having a namesake in "Toad", was named after Scotland Yard (whose actual name is "New Scotland Yard"), a British police headquarters. Scotland Yard is famous for being included in several fictional crime stories such as those involving the famous detective Sherlock Holmes, who happens to be Shroomlock's namesake. (Interestingly, in Sherlock Holmes stories involving Scotland Yard, Holmes, unlike Shroomlock, did not work for the headquarters; instead, he often teamed up or even competed with its operatives.)
