List of implied items
The following list of implied items is a list of items, objects, and foods that have not physically appeared in any form of media up to this point in time. Regardless of their lack of appearance, the implied items have been mentioned at least once throughout the Mario series.
A Blank Mushroom is mentioned in Mario & Luigi: Bowser's Inside Story by a Toad girl in Toadley Clinic. She said that her big brother probably ate one of those, and so, his mind became modified. He was talking about the things he remembered: first he was in a house in Plack Beach, and then in a cold room in Bowser Castle where he saw a Mushroom shape. This is a hint to find the two hidden Special Attacks for Mario & Luigi: Spin Pipe and Magic Window. The Mushroom shape in the cold room (the Preservation Chamber) refers to the optional boss: the Shroobs.
A Blorb Mushroom is mentioned in Mario & Luigi: Bowser's Inside Story. It is given to Mushroom Kingdom citizens from a merchant in a cape from another kingdom. Eating it causes Toads to get the Blorbs and puff up to enormous sizes. With this swelling comes rolling about the kingdom, usually blocking many pathways for all denizens. This condition can be removed only by the Miracle Cure; however, certain other medicines can ease the swelling. It is one of the two mushrooms (the other being the Vacuum Shroom) to be invented by Fawful.
Demented by Dimentio
Demented is apparently Dimentio's brand of fragrance and perfume. In Chapter 8-3 of Super Paper Mario, Dimentio is confronted by Mario, Luigi and the Pixls. He informs them of his plan to betray Count Bleck and usurp the Chaos Heart, and, after forcing them to play a magical game of tag with him, he offers them a list of bribes. Among the other items in this list, Dimentio mentions a signed bottle of his perfume, claiming that, if Mario and Luigi were to wear it, people would "stand in ovation whenever they enter a room".
The Dramalama Plaque is the prize for winning the Jazzafrazz Town Drama Slam, in Paper Mario: The Thousand-Year Door. As it happened, the Marvelous Compass piece that Luigi needed was embedded in the plaque. With the help of the Crazee Dayzee Hayzee, Luigi won the plaque and he could continue his journey.
The Fat Dog is mentioned Paper Mario: The Thousand-Year Door. When Mario gives the Businessman his briefcase combination, the Ratooey says that his company and Hoggle's Hot Dog stand were going to join the Fat Dog and Hot Sauce into one product.
Flipside Tower Postcard
In one of his stories of the Super Luigi series from Paper Mario: The Thousand-Year Door, Luigi claims he collected the seven pieces of the Marvelous Compass during his adventure. According to Luigi, the Marvelous Compass was originally used by the ancient Luff empire. The compass had the power to see into the future, and the Luffs used this ability to conquer many lands. The empire became corrupt, however, under its increasing power and eventually collapsed. To prevent the artifact from being misused again, the compass was split into seven pieces to be scattered across the world. Cranberry, the last of the Luffs, was charged with protecting one piece of the compass and would give it only to one pure of heart.
Luigi had to collect the seven pieces of the Marvelous Compass to locate Princess Eclair, who had been kidnapped by the Chestnut King. Each piece of the compass would point to where the next piece could be located. Since a piece of the compass was embedded in Eclair's crown, Luigi could use to compass to locate her.
Eventually, Luigi collected six of the seven compass pieces and traveled to Hatesong Tower, the location of Princess Eclair and the last compass piece. Upon entering, Luigi was attacked by the Chestnut King. The two fought a tremendous battle. However, the fight was interrupted by Princess Eclair. As it turned out, the Chestnut King and Eclair were lovers. Minister Crepe, the minister of the Waffle Kingdom who summoned Luigi to find the princess, was, in fact, the true villain. He had orchestrated events so Luigi would retrieve the Marvelous Compass on his behalf. Crepe wanted to use the compass's precognitive power to see into the future so that he could conquer the Waffle Kingdom and resurrect the Luff empire. However, Crepe was defeated by Luigi, who used the compass to predict Crepe's attacks.
The Marvelous Compass is a reference to the storyline of Paper Mario: The Thousand-Year Door in that he was meant to gather the compass pieces (or the Crystal Stars in Mario's case), but in the end he was tricked. The way the compass pieces all point to the next parallels the Crystal Stars pointing to the next one via the magical map.

Mushroom Full Course
The Mushroom Full Course can first be mentioned in the afternoon of Mario's second day riding the Excess Express, shortly before its arrival at Riverside Station. Chef Shimi has claimed that it is his "super-duper specialty". Talking to him during the afternoon will allow Mario to discover that he was currently working on a Mushroom Full Course meal for that night. Shimi also lists the process to prepare the Mushroom Full Course: Apparently, a Mushroom Full Course starts with Mushroom bouillon, followed by Mushroom mousse, and then Mushrooms in the spice saffron. A "delicate but puzzling" Mushroom sorbet is given as dessert in the Mushroom Full Course, which is ultimately ended with Mushroom coffee. Shimi additionally states that he is serving it and he has hand-picked the Mushrooms for that night's Mushroom Full Course at Riverside Station. At this, Mario's partner questions the Mushrooms' edibility.
The Toad Waitress at the same time period also mentions the Mushroom Full Course, stating that it is being served as they speak, before pondering why Chef Shimi always uses Mushrooms in his meals. Later, Shimi's lack of culinary skill with anything but Mushrooms would become a bit of a recurring joke in Paper Mario: The Thousand-Year Door.
A Nibble-Um is a snack briefly mentioned in Super Paper Mario. When Francis is about to make Tiptron Mk. II, he orders his Meowmaids to bring him some Nibble-Ums, which seems to be a cheesy snack. Nibble-Ums are probably based on Cheez-Its, a cheesy snack brand in real life.
Nitro Honey Syrup
Nitro Honey Syrup is a special syrup (presumably a sort of Honey Syrup) mentioned in Paper Mario: The Thousand-Year Door. Although Nitro Honey Syrup was never produced, recipes for it can be found apparently in the Businessman's briefcase. Although it is normally powerful enough to perform miraculous acts such as raising the dead, it becomes explosive when mixed with calcium and gold. The Shadow Sirens, wishing to destroy the Excess Express (which Mario was riding at the time) in a "sticky, yummy explosion", decided to send Doopliss onto the Excess Express and have him steal the Nitro Honey Syrup recipe, correctly mix it into an explosive form (with help from Toodles's Gold Ring and the Toad Waitress's Shell Earrings), and finally destroy Mario. They would then frame Zip Toad (who Doopliss is disguised as at the time) for the crime so they escape with the Garnet Star. However, they failed at doing so, and Nitro Honey Syrup is never mentioned again.
In "Jungle Fever", Butterfingers, the assistant of the famous witch doctor, Dr. Sheldon, attempts to create a batch of No-Itch Potion. Butterfingers fails to create any No-Itch Potion, however, only creating some sort of duplication potion, instead of properly treating Mario, Luigi and Toad's itchiness.
The Parascope is an unseen device invented by Professor E. Gadd that is used to detect and measure paranormal signals in Luigi's Mansion: Dark Moon. It allows him to track ghosts and locate areas of ghostly activity that he can then relay to Luigi via the Dual Scream's map. As more powerful ghosts are captured, E. Gadd can fine-tune the Parascope to enhance its detection capabilities, and as more pieces of the shattered Dark Moon are collected, he is able to pinpoint the locations of the other missing pieces more accurately. Bearing its name, the Parascope can detect only paranormal phenomena and Dark Moon pieces and not physical objects that Luigi may need to retrieve to progress through a mansion.
The Plumber's Log is an unseen log book of Mario's that he uses to record his adventures throughout the animated segments of The Super Mario Bros. Super Show!. The log is a reference to Star Trek's "Captain's Log". At the beginning of every episode, Mario quotes (in a voiceover) a brief entry from his Plumber's Log, usually explaining where he and his friends has traveled to, why they are there, and what they are about to encounter. Each Plumber's Log has its own numbered entry, although there does not appear to be any plausible or chronological order to them in regards to the order of the episodes.
Note: Each Plumber's Log entry is written the way Mario pronounces it. For instance, the Plumber's Log for the first episode is written as "1-0-1", because Mario reads it as "one-zero-one", as opposed to "one-hundred-one". However, there are a few entry numbers that this rule does not apply to, usually because the number has an actual meaning (for example, the number is a year).
The Poison 1-Up is an item mentioned in Super Paper Mario, when Mario and co. are visiting the Underwhere. The Shaydes in the Underwhere will tell Mario and co. stories of how they died. One of the Shaydes will tell how he died by means of a Poison 1-Up. It is unknown as to what this item looks like, however it probably looks comparable to a Poison Mushroom. It is also possible that the creators of the game actually meant to say Poison Mushroom, and that Poison 1-Up was simply a mistake.
The Reclinatron 4500 is a type of chair mentioned only in Super Paper Mario. When in Castle Bleck, Mimi, disguised as Merlee, will ask Mario three questions about what he hates the most. On the third question, one answer is "Francis". If the player selects this, Mimi will somehow teleport Francis to a room in the castle. When Mario enters this room, Francis is confused about why he is there, then decides that because he was thinking about Francine, his Reclinatron 4500 teleported him there. Francis then battles and loses to Mario.

Saffron Special Galactic Meal
The Saffron Special Galactic Meal is a meal which is mentioned by Carson in The Overthere coffee bar. When Merlon was in love with Saffron the chef, he asked her to go out with him. She said she only wanted to go out if he managed to make a Saffron Special Galactic Meal. When Merlon was almost finished, and only had to finish the parsley, he heard of a girl who had appeared in Flipside. He hasted himself to the girl, and the parsley was left behind. Merlon never returned to finish the challenge, and never attempted it again.
A Sammy is a prize given away at the Sammer Awards in Sammer's Kingdom. It is mentioned in Super Paper Mario, when the player finishes the game, goes back to Sammer's Kingdom and finishes the Duel of 100. When using Tattle on End Boss, the final Sammer Guy, Tiptron will say that he won a Sammy at last year's Sammer Awards for Best Final Boss Performance. It is a pun on a Grammy.
Southern Fried Egg Dog of Tastiness
The Southern Fried Egg Dog of Tastiness was a Hot Dog that Mr. Hoggle was going to create out of a Hot Dog and a Southern Yoshi Egg in Paper Mario: The Thousand-Year Door. It was supposedly going to taste delicious and make fighters stronger. However, since Mario rescued the Yoshi Egg, this Hot Dog was never actually created, therefore, Mr. Hoggle could not sell it at his shop in Glitzville.
Super Mega Ultra Shroom
A Super Mega Ultra Shroom is a Mushroom that was mentioned by Mimi in Super Paper Mario. It may be assumed that there is no such mushroom as Mimi was disguised as Merlee and was offering various things (similar to Hooktail) to Mario and his party, claiming she would give him it along with the Pure Heart if they signed a contract to pay ten million Rubees.
Tongue-Blistering Fat Dog
The Tongue-Blistering Fat Dog is a cancelled product made by the Businessman's company and Mr. Hoggle's Hot Dog business. It was briefly mentioned in Paper Mario: The Thousand-Year Door. After Mario got the Ratooey's briefcase combination, he walked over to the Hot Dog Stand and had a short discussion. He then told Mario that his new product was cancelled, the Tongue-Blistering Fat Dog. He said that it would be a combination of his company's Hot Sauce on Hoggle's Fat Dog.
The Big Green 01
The Big Green 01 is a kart used by Luigi in Paper Mario: The Thousand-Year Door. It is implied that Torque, the Buzzy Beetle, made it and then let Luigi use it because he got down on his knees and begged. Luigi then wrecked it almost the second the race started. He then owed Torque 5,000 coins to repair the kart.
Universal Gravitation Device
The Universal Gravitation Device was an unseen item given to Yoshi by the spirit Hongo in Yoshi Topsy-Turvy, however considering that the player controls the gravity via Game Boy Advance, it's possible its appearance resembles one.
It allowed Yoshi to manipulate the gravity of levels; the player can turn them on their sides, roll or unroll things, etc. This allows Yoshi to access parts of levels that he wouldn't be able to normally, such as being able to climb up walls/ceilings by literally walking up them, or move objects by merely tilting them on their side and making it roll for example.
