Count Bleck's World
Count Bleck's World or Blumiere's World is a world that Count Bleck says he is going to create after destroying all worlds in Super Paper Mario, and live there with his minions, Mimi, Nastasia, O'Chunks and Dimentio happily.

Dimentio says Count Bleck lied about the World and tries to convince Mario to join him to build perfect worlds, but Tippi alerts him he is lying, causing Dimentio to fight Mario.
At the end of the game, Lord Blumiere and Lady Timpani (Count Bleck and Tippi's true forms) go to some other world where they presumably live happily ever after. After Mario and company all return to Flipside, Nastasia is sad 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 and not war.
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 is 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 impeachment, 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 existence are the Dry Dry Ruins, which are guarded by Moustafa, a possible descendant of King Mousta or his second-in-command, a thief boss who is charged with guarding the ruins.
The Flora Kingdom is a civilization referenced in Super Paper Mario. Floro Sapiens are the residents and King Croacus IV is the current king of the kingdom. Though it is not confirmed, the Floro Caverns are likely part of the Flora Kingdom, as many Floro Sapiens are seen there, and it is where King Croacus' room is located. The previous rulers of the Flora Kingdom were King Croacus I, Queen Croacus II and King Croacus III.

Plumpbelly Village is a town on the Strudel Continent, possibly ruled by the Waffle Kingdom. It is the location of one of the pieces of the Marvelous Compass that Luigi retrieve during the events of Paper Mario: The Thousand-Year Door.
When Luigi arrives, the town is ruled by a two-headed snake named Hizza, who demands regular sacrifices of the village's women.

Jerry, the cherry-shaped Bob-omb, horrified by the sight of Luigi in a dress, followed him to try and stop him, but Hizza takes Luigi into his lair.

After Luigi emerges with the Marvelous Compass piece that Hizza was guarding, the mayor offers his daughter's hand in marriage.

Squirpia is a long-forgotten kingdom mentioned in Super Paper Mario, that once existed in Outer Space. It is mentioned in-game that 1,500 years ago, the Tribe of Ancients visited Squirpina XIV, the then-queen of Squirpia, and entrusted her with the Blue Pure Heart. In order to protect the world, Squirpina hid the treasure in the Whoa Zone, an apparently important place to the kingdom, and proceeded to place her young son Squirps inside a hibernation capsule, so that, when the time came, he would be able to guide the heroes to the Pure Heart in order to collect it.
Squirps explains his story to the heroes at the end of Chapter 4; however, he does not make it clear how Squirpia fell, and so the reason is left unknown throughout the rest of the game. Following the defeat of the final boss, the young prince can be found speaking to a statue of his mother in the Whoa Zone, where he declares that he will restore his kingdom someday. He is never shown to accomplish this goal.

After Mario leaves home to find Princess Peach in the town of Rogueport, Luigi is once again left alone. However, a letter arrives for the Mario Bros., which Luigi can't resist to peek at. The letter was from Minister Crepe, the Minister of the Waffle Kingdom. According to the letter, the lovely Princess Eclair was kidnapped by the Chestnut King and the kingdom needed assistance from the great hero Mario. However, since Mario was not around, Luigi went in his place.
When Luigi arrives in the Waffle Kingdom, he is given a piece of the Marvelous Compass. If Luigi could find all the pieces, he would be able to track down Princess Eclair. After much toil and trouble (and quite a bit of luck), Luigi collects all the pieces and heads to Hatesong Tower to find the princess. However, he actually finds the evil Chestnut King, and the two engage in an epic battle. Ultimately Princess Eclair appears and interrupts the battle. Apparently, the princess and the Chestnut King were lovers but the king was transformed into a monster by Minister Crepe, who was in fact a dark sorcerer. As it turns out, Crepe had orchestrated events so that Luigi would reassemble the Magical Compass for him. Once he had the compass, Crepe would use its power to conquer the Waffle Kingdom, saying the Luff empire will rise again. However, Luigi and his allies defeat the shadowy Crepe. As a result, peace is returned to the Waffle Kingdom.
