List of Super Mario Galaxy pre-release and unused content

This is a list of pre-release and unused content for the game Super Mario Galaxy.

Early concepts
The official Prima Games guide for Super Mario Galaxy was released in two editions: the Premiere Edition and the Collector's Edition. Among the features included in the Collector's Edition were six pages of concept art and development info from the game's developers.

Rosalina was intended to be related to Princess Peach. They have very similar appearances, reflecting this. Her original design would've portrayed Rosalina with a beehive hairdo and a ballroom gown similar to that of Peach's, while her finalized design portrayed her with a similar hairstyle as Peach's, although with some differences such as her sporting a large bang covering her right eye, and her outfit was redesigned to look more like a nightgown. Bonefin Galaxy was intended to be much darker, as was Deep Dark Galaxy. These were changed in the interest of playability. Guppy was originally a dolphin, and a friendly character. Some art of the Sea Slide and Beach Bowl Galaxies suggests that they were conceived as a single galaxy, with Beach Bowl's main planet in the center of Sea Slide's ring.

A piece of concept art labeled only "fortress" is captioned as a piece that is very memorable to the Super Mario Galaxy development team, since it was one of the earliest drawings of Galaxy. In spite of this, the planet shown in the art is nowhere in the final game, though aspects of it exist across several planets. This unused fortress, dubbed "Starman Fort" internally, does still have some assets remaining in the code, and can actually be pieced back together for the most part. Several cannons and the waterfall are missing, and the underside of the fortress where Mario fights BossCrab is not programmed.

At one point, Yoshi was going to accompany Mario in his adventures in space, while Starship Mario was going to be the game's hub level instead of the Comet Observatory. Both did not appear until the sequel, although a planet shaped like Yoshi's head made a brief appearance in the Space Junk Galaxy.

Press kits
Many things had different names in pre-release info. For example, the character Rosalina went by her Japanese name, "Rosetta," which comes from a type of orbit.

Also, several things underwent graphical changes:
 * As seen in one of the IGN.com screenshots, Bowser was originally going to be fought on an arena on a magma planet instead of a glassy planet in the released game.
 * The red Pokey seen in Dusty Dune Galaxy was originally green.

In this screenshot, the player has collected only 19 Power Stars and 3 Grand Stars, but has access to the Trial Galaxies.

E3 2006 (May 10-12)
E3 2006 was the first event in which Nintendo publicly showed Super Mario Galaxy in anything akin to its final form, although it was quite different from the final game. In this prototype build, attendees were treated to a single-galaxy demo of the game, in which they were given ten minutes to find and collect a star. This build had many differences from the final game, although all the basic principles of the game existed in some form.
 * Some game mechanics eventually changed:
 * Mario had the ability to spin to attract coins to him, which he lost in the final version. He can still do this as Flying Mario and underwater.
 * In this version of the game Mario could spin multiple times in a row. In the final version, a small delay is enforced during Spins.
 * In this prototype, players had to hold and point at Star Bits to grab them. This was later changed because the developers settled on using the  button to fire Star Bits (which was impossible at this point).
 * Mario could kick Star Bits around.
 * Mario's Star Cursor was more powerful. It had many of the powers given to the second player's cursor in the final game, such as holding enemies.
 * The Life Meter was more like the one in Super Mario 64, having a total of eight health, and changing color more like the Super Mario 64 version. This was changed to three wedges in the final version.
 * Like Super Mario Sunshine, the early life meter would fluctuate in size. Getting faster the lower Mario's health is.
 * At this point, notes had an on screen counter, showing players how many notes they had collected, as well as how many there were total.
 * Here, if a player wanted to use a Pull Star (or what would eventually be called a Pull Star), they would need to point at it constantly, as moving the star cursor too far away would deactivate it. In the final game, the Pull Star will remain active until players release the button.
 * If a character wanted to talk to Mario, an exclamation point in a thought bubble would appear above its head. When Mario got close to that character, its dialogue would appear onscreen without interrupting gameplay.
 * When the player pulled on a sling pod a blue arrow will show the direction Mario is going to go; if the player took the cursor off screen, the arrow would turn red and a beeping sound would play.
 * The player would use the button to use sling pods. In the final version of the game, the player would use.
 * When the player grabbed a coin, the coin sound effect can be heard on the Wii Remote's speaker.
 * When the player attacked a Goomba, it did not spin after being launched.
 * Some graphics were not complete, or were different:
 * The Star Bit counter said 0/100 in this version. No attendee to E3 collected all 100 of the galaxy's "star shards" (as they were then known), so their purpose is unknown.
 * The Star Cursor was yellow in color, and it had a longer "tail." It flashed red if players were not pointing the Wii remote at the screen.
 * Slurples were colored purple.
 * Speech bubbles had a cloudlike design.
 * The message "You Got a Star!" was white, and written in all caps. This is changed to green in the final version. The "Too Bad!" text was the same but it later changed to red letters in the final version.
 * The HUD effects for using a Sling Pod were different. These can be seen in the Tarantox videos.
 * The Mario head used as a lives counter was captioned "MARIO."
 * The HUD design used the number font from Super Mario Sunshine.
 * One-ups used a simpler, green "1up!" effect when collected.
 * Certain sound effects were substituted out for others, usually because not all sound composition was complete:
 * When Mario grabbed a star, the music was a remix of the goal tune from the original Super Mario Bros..
 * Mario's voice clips from Super Mario Sunshine were used as a placeholder.
 * A different sound effect was used for grabbing Star Bits.
 * A slightly simpler sound effect was used for 1-Up collection.
 * When flying after being shot from a Launch Star, a synthesized drum beat was playing over the music.
 * A few things also existed under different names:
 * Star Bits were called "star shards".
 * Launch/Sling Stars were simply "stars".
 * Pull Stars were called "blue stars".
 * Sling Pods were called "wobble launchers".

Star World
The Star World, as titled in the introductory "Welcome to the Star World!" message, was the demonstration galaxy created to show off Super Mario Galaxy for E3 2006. It was composed of many planets taken from other galaxies in the game. It was notably different from any galaxy in the final game in that it was composed of a "branching" path; choosing different routes on different planets could lead to different stars entirely. It is likely this was done for the demo specifically. It was also notable for its heavy use of asteroids instead of unique planets. The final game ended up using these asteroids only twice, as moons in two galaxies. The level compiled many different planets into the galaxy, most of which became planets in Good Egg Galaxy, Space Junk Galaxy, and Bowser Jr's Robot Reactor.

This galaxy was inhabited by rabbits and the conjecturally named, who were distinguished from normal Toads by the star shaped spots on their caps. They gave players hints and explained the controls. Sometimes, the rabbits could change into. Their role was likely replaced by Lumas. They explained various aspects of the game to Mario.

At least three routes through the galaxy were discovered by attendees to the show. The stars were guarded by King Kaliente, Tarantox, and Megaleg.

The music that plays in this galaxy is known as "Egg Planet." It is the theme of Good Egg Galaxy in the final game, though it sounds noticeably different.

In this version, when Mario falls into a black hole, he has an oval like line.

Since this galaxy was compiled into a build that allowed Mario's Star Cursor to hold enemies, some of its puzzles made use of that.

Bosses
Megaleg was notably different from the final game's Megaleg. It was not commanded by Bowser Jr, and not powered by a Star. The weak point started out blue, and became red once the outer protective layer was broken (in the final game, it starts out white, then turns pink). Also, the rotating light source is inside the glass dome on top of Megaleg, as opposed to on top of it. Megaleg has a small depression on the top of its head, which Megaleg did not. Megaleg had three coins near each of the two metal patches on its head, and two coins on each leg, making the battle somewhat easier for players. After it was hit for the first time, it guarded its weak point with four unbreakable walls, rather than eight breakable ones. When Megaleg is defeated, its head smokes, which does not happen to Megaleg. Megaleg guarded a normal Power Star, as opposed to a Grand Star. It also has spikes on its legs, which are gone in the final game.

Tarantox was also different, though not nearly as much so as Megaleg. Attacking any of the fluid filled green sacs on it was enough to flip it over, while in the final game, only the large one on its bottom is sufficient. Once the red sacs on its belly have been destroyed one time each, the final versions Tarantox will regrow all of the green sacs. Not so for the Star World's Tarantox. The red sacs on the Star World's Tarantox also pulsate more, and with a higher pitched sound effect.

King Kaliente's battle was somewhat identical to his battle in the released game. The major difference observed is that the flaming projectiles he shot could be batted away with the star cursor. His phases also changed from E3 2006 to the final version. Traditionally, the player would deflect King Kaliente's coconuts once in phase one, twice in phase two, and three times in phase three. However, in the demo, there were only two phases in which the player had to deflect the coconuts three times. This was likely changed to lower the initial difficulty.

All three bosses did not release Star Bits when attacked, since there were only 100 Star Bits in the whole galaxy. However, no attendee to the show ever collected all of them, so their purpose remains unknown (they could not be fired at enemies as they are in the final game).

HomePlanet
"HomePlanet" as it is called internally by the game's files is the only planet not present in the final game in some form. Its model data is still present, but is never used. After Mario is released from the bubble, he lands on this planet.



The planet has multiple different sections. Most of it is covered in grass, with dirt marking a pathway to the Sling Star. Small eggs with stars plastered on them around the outskirts of the planet indicate this planet was originally part of Good Egg Galaxy. There is also a small beach section on the left side of the planet. Heading down the pathway leads the player to a small gate, where using the cursor to ring the bells allows the player to collect 20 music notes. Continuing down the pathway leads to a small incline, and then there are two small jumps the player had to make to get to the Sling Star. This launches the player to the top of the planet, which has a Launch Star and leads to a pair of asteroid planets.

Glassy Twin Planets A & B
Following HomePlanet are two identical asteroid planets. The first one has star bits surrounding the entire planet while the second has star bits on one side of the planet. The player also lands on a star bit, where a Cosmic Toad explains how to collect the star bits. Multiple Goombas can be found on both planets. These planets also have some plants on them.

Using a Sling Star, the player could launch over to the second asteroid. The second asteroid also has a Sling Star, which launches the player to the next planet.

It is likely these asteroids were named GlassyTwinsPlanetA & B. However, according to the files, these asteroids were later updated.

DiskFlowerPlanet


The first planet from Good Egg Galaxy, named DiskGardenPlanet in the final version, is shown in a drastically different form here. Firstly, the planet's filename is instead "DiskFlowerPlanet". The house is more akin to a real life one, and pine tree appears in this version as opposed to a more traditional Mario-style tree in the final version. There is also different placements for the patches of grass and dirt, with there being 4 patches instead of 2.

The bridges leading to the other side of the planet are also slightly altered. The left side has a slightly different design, and arrows pointing to the player which direction they have to go. The right side also does this. The right bridge also has a different color for the floor, and the sides of the bridge are now red instead of black. The planet also looks slightly more decayed on the darker side compared to the final version, especially around the tower. The trees also have a different shape and texture.

When Mario lands on this planet, he was greeted by 2 Star Bunnies, which could transform into Cosmic Toads, and following one of them led to one of two different paths. If the player took the left bridge, they are led up the tower, which is mostly identical to the final version. This led to a Pull Star, which led to a Sling Star, which led to a Launch Star, which took the player to the Tropical Planets. In the final version, the roof of the house is what took the player to the Tropical Planets. From here, the mission plays out very similarly to King Kaliente's Battle Fleet. If the player took the right bridge, they were led to the twisty walkway. However, it was altered. Firstly, there were no stairs to get up. Instead, the player had to use two Pull Stars. The twisty walkway itself was very different. This led the player to the Pull Star section from Space Junk Galaxy.

G Capture Tutorial Zone
This section is used in most missions in Space Junk Galaxy, and is almost identical to the final version. Like the final version, going down took the player to the Glass Maze Planet, and leads to Tarantox. However, heading up led the player to a small relay planet, which took the player across several planets leading to Megaleg.

Tropical Planets
These two Tropical Planets are taken from King Kaliente's Battle Fleet, which is the 3rd mission in Good Egg Galaxy. The position of the planets were different to the final. Mario also landed on a different spot on the planet. More coconuts and crates are present on the first planet compared to the final. Another change is that the palm tree on the first planet was slightly bigger. Also, no water patches or crystals were present here. Instead of having to break a thorny flower to activate a Sling Star which takes the player to the next planet, the Sling Star is already activated. The second planet remains mostly the same, however there is a Sling Star on the bottom of this planet for an unknown reason. Defeating the Big Pokey still takes the player to the Asteroid Planet, but they use a Sling Star before using the Launch Star. There is also a different flight and camera sequence.

Asteroid Planet
This planet remains mostly the same. Two differences are that there are no Chomps and there is no pipe on the bottom side. Another change is that rocks surround this and the Chomp Saucer Planet.

Chomp Saucer Planet
This planet only received minor changes. In the E3 version, the player does not land in the center of the planet. The rocks, lasers and Goombas are placed in different spots as well. The bottom stone slab of the staircase is missing, and there are 3 steps on the tiny staircase instead of 2 in the final. The amps are also missing. The crystal usually present on the very top of the planet isn't there as well.

Octopus Airships
When landing on the planet in this version, the music stays the same, instead of playing "Tension". The Airships also have a slightly different design. There is also an inaccessible door on the right side, where a wooden platform and 3 crates are placed. The toad is also not frozen unlike the final. The Black Hole is closer to the ship, the stairs are wider, the extension of the second airship which contains a life mushroom isn't there, there is one set of stairs instead of multiple, the airship is taller, there are only two electrogoombas where there are 4 in the final, and there is a Sling Star instead of a Launch Star leading to King Kaliente's Planet.

King Kaliente's Planet
Apart from the fight itself, this planet remains mostly the same aside from the Luma and Star Bit crystals not being present.

Relay Planet C
This is a small wooden planet that leads to the Boulder Planet that is only found in the demo. There was also a sign that said "This way to the P-Nut Star".

Boulder Planet
"PeanutPlanet" as it is known in the files was an early version of the Boulder Planet, but without the Star Chips and mud. The player had to simply navigate around a few boulders to reach the end of the planet. The Boulders would break upon smashing into them, and spinning them would instantly destroy them. They also do not have a weak spot in this version.

Hole Planet
This planet is the starting planet from Bowser Jr's Robot Reactor. However, it is grassy, as opposed to metallic. It has a design similar to the second planet in Gateway Galaxy, except bigger. A minor glitch in the released game causes the grassy version of this planet to appear if players stand on top of Megaleg and look at the metallic version. This is caused by an incorrectly set-up culling method. When the planet was redesigned, its low-poly model was not.

Megaleg's Planet
Apart from the fight itself, this planet is exactly the same as the final version.

Glass Maze Planet
This planet is taken from Tarantox's Tangled Web in Space Junk Galaxy. Most of this planet remains the same, however there seemed to be less enemies and there is a Star Bunny that would lead the player through the maze and to the star, instead of the player finding their way all on their own.

Grave Stone A, B & C
These 3 Grave Stone Planets are found in the final game as well. In the demo, they appear to be more decayed, and lack the Spoings that appear in the final.

Planet Rocket
This planet is almost identical to the final, but lacks crystals and Spoings.

Phantom Boss Spider Zone
Apart from the fight itself, the planet itself is almost completely identical to the final version.

GDC 2007 (March 5-9)
Although no playable version of Super Mario Galaxy was shown at Game Developer's Conference 2007, a trailer was released, showing a much more complete version of Galaxy.

Scene 1

 * A Pull Star was used to climb on top of the house in Good Egg Galaxy. The house is the same from the E3 demo, and lacks the orange pipe, and the Launch Star fires Mario to the Egg planet from Good Egg's second mission, rather than the tropical planets from Good Egg's third mission.

Scene 2

 * The volcano in Melty Molten Galaxy has a different design, reminiscent of volcanic glass.

Scene 3

 * The Boulder Planet from Good Egg Galaxy's first mission is still the same as it was in Star World.

Scene 4

 * The boulders have a different model, without the red spot. Mario can break them by spinning at them at any time or colliding with them.
 * Star Chips aren't on this planet, just like in Star World. However, there would instead be a crystal that had to be broken to continue the level.

Scene 5

 * 3 Bean Planets are shown in this scene. Only 1 is in Good Egg in the final game, and there is no Stone Platform. There was also no Piranha Plant where the vine would spawn.

Scene 6

 * Honeyhive Galaxy received several changes. The Mushroom Twin Planets have different enemy placement. Wigglers are on the first planet in this trailer instead of the second in the final, and Goombas are on the second planet.
 * The Starting Planet in Honeyhive's first mission seems to have more wood on the main planet, and an unused wooden tower can be seen on the planet as well.
 * This scene also seems to show that Honeyhive and Gold Leaf Galaxy would have been a single galaxy at some point. Almost every planet from Gold Leaf is present in this shot.
 * The flower planet in Honeyhive's first mission is in a different position.

Scene 7

 * For an unknown reason, a certain Launch Star leaves a red trail, although the Launch Star is the normal color.
 * This shot seems to show the player would not start on the House Planet like in the final, as three unused planets are shown behind it, with a Launch Star trail leading to the House Planet.

Scene 9

 * Both of the Starshrooms at the beginning of the Space Junk Galaxy are red.
 * The Airships and Tarantox's planet are still shown in the background of Space Junk when they are not in the final, as in the final they are only present in their single mission.

Scene 10

 * The Life Mushroom has not yet been added into the area of Melty Molten Galaxy with miniature suns, for obvious reasons.
 * Mario has a different burning sound effect when he screams.

Scene 11

 * Gusty Garden Galaxy has a background similar to Good Egg Galaxy. This seems to be a very early version of Gusty Garden, as most planets have either been changed or are nowhere to be seen in the final, apart from the Apple Planets.

Scene 12

 * Melty Molten Galaxy originally featured Topmen, as well as some other elements and planets from Dreadnought Galaxy.
 * The second planet in the third mission of Dreadnought Galaxy is unseen. Only the UFO and Cube Planet are visible.
 * Electrogoombas are present here, where they are nowhere in Melty Molten in the final.

Scene 13

 * In this scene, a Launch Star actually fires Mario through one of the hardened lava structures in Melty Molten Galaxy. This was never included in the final product.
 * Electrogoombas are in place of Li'l Cinders.

Scene 14

 * Topmaniac appears, with a much different design.

Scene 15

 * An area appears in the video in which there are many sinking platforms above lava. Though this area has many coins in the video, they have all become Star Bits in the final game. The final game's Lumalee is also missing.

Scene 16

 * Electrogoombas seem to have a different animation, also present in Star World.

Scene 18

 * A crate is in front of the cave in which Beach Bowl Galaxy's Gringill lives.

Scene 20

 * More removed planets from Gusty Garden are shown here, and the Stone Planet is also changed. The Floaty Fluff also had a slightly different animation.

Other changes

 * The music in the trailer is an early version of Egg Planet, which is used in Good Egg Galaxy. (This is also used in the E3 2006 demo.)
 * A second design of the Health Meter was used, this one identical to the first except with the green and blue colors swapped.
 * The Star Bit counter is still of the format 0/100
 * The air meter has a different, bubble-like design.
 * Mario can still spin to attract coins.
 * The trailer shows that in this build of the game, touching lava would reduce the health meter by three, similar to Super Mario 64.
 * The Star Cursor is still designed like the one in the Star World era builds. However, it has the shorter tail of the modern star cursor.
 * Star Bits still had a different sound effect compared to the final.
 * Lots of enemies are missing. This is likely due to not being programmed yet or just not being placed on their respective planets yet.
 * Good Egg Galaxy has a slightly darker background.
 * The low-poly model for the Tower Planet in Good Egg Galaxy is shown here as a full planet in Good Egg, seen in multiple shots.
 * It appears already activated Launch Stars would have remained present in multiple missions for some galaxies, as shown frequently in Good Egg Galaxy.
 * The palm tree from Good Egg Galaxy's first Tropical planet is missing.
 * Some planets seem to be detailed even when far away, instead of in the final when planet models don't render properly unless close to it.
 * The Egg Planet from Good Egg Galaxy seems to be facing at a straight, vertical angle, instead of being slightly tilted like the final version.
 * Most planets lack crystals in this version, mainly Good Egg Galaxy.

E3 2007 (July 10-13)
Since E3 was downsized to the E3 Media and Business Summit in 2007, less Galaxy info was released than in 2006. The first Galaxy related content was a press conference video, which was very close to the final game.


 * This is the first video to show Mario with a health meter with three sections.
 * Good Egg Galaxy's background and music are still unchanged, meaning they were likely changed late in development.
 * The star cursor now has its final design, and co-op mode is first seen. However, the two star cursors are not labeled P1 and P2, as they are in the final game.
 * The fly meter has a bubble-like design.
 * An area of the Honeyhive Galaxy is shown in which two rings of Star Bits float above purple flower platforms. In the final game, these are coins.
 * The Star Bit counter is now of the format 000 (it shows all three digits, even when they are zeros).
 * Players no longer needs to hold to collect Star Bits.
 * Shrinking green platforms (from the Hurry-Scurry Galaxy) do not have a silver border.
 * The vault room in Ghostly Galaxy has Star Bits, rather than coins.
 * In the presentation after the trailer, changes in Gusty Garden Galaxy can be spotted. Mainly, the Apple Planets are found in between where the Grassy Spheres Planet and Disk Planet would be, the Grassy Spheres Planet is found below where the Apple Planets would be, there is an extra Hedge Planet and the spiky planet before Major Burrows is missing.

Later on, attendees were allowed to play a demo of the game, from which they had access to Good Egg Galaxy, Honeyhive Galaxy, and Space Junk Galaxy. The press conference video above is not from this demo, but from a very slightly earlier build of the game. Some videos taken by attendees reveal differences from the released game.


 * There are scuff marks from the boulders in the final game.
 * The ? Block is a ? Coin in the final game.


 * Here we can see early names for several things.
 * The "Space Junk Galaxy" was called "Star Dust Galaxy." This is also the galaxy's name in the Japanese version.
 * The first star of that galaxy was called "The Beam Star Trail" ("Pull Star Path" in the final game).
 * Thus, "Pull Stars" were known as "Beam Stars."
 * In the opening movie to a galaxy, the name of the current star is printed at the top of the screen, while the galaxy's name is at the bottom. In the final game, both are at the top, with the star's name below the galaxy's name.
 * Here, the message "Point at the screen with [the Wii Remote]" is aligned with the left side of the screen, rather than centered. "Aim at [the beam star] and press [A]." is similar.
 * One coin featured in this demo version is missing from the final game.


 * Matt Casamassina (the man playing the demo) refers to the galaxy as the "Honeybee Kingdom." However, this is not seen on-screen.
 * Once again, there are Star Bits above the purple flowers.


 * The Luma on top of the tower says "My comrades are ahead... Hurry!" In the final game it says "My friends are ahead. Hurry!"
 * The text is also vertically centered in the final game, which is not true here.
 * The Luma who explains coins is not present.
 * Mr. Casamassina refers to the Star Chips as "little triangles," suggesting that the players weren't given their true name.


 * Captain Olimar's ship does not have crystals holding coins on its windows.
 * One of the asteroids flanking the Beam Star trail is flatter and thinner than in the final game. (The round asteroid with green gems in it.)


 * Mr. Casamassina says that player 2 uses the B trigger to hold enemies, but in the final game, the A button does this.
 * The red plant next to the Piranha Plant in the video is not in the final game. Instead, the Piranha Plant is surrounded by green stretchy plants.

GC 2007 (August 23-26)
A demo of Galaxy was featured at Games Conference 2007. It is believed to be the same as the demo from E3 2007.


 * In this video, the bee says "Welcome to the Honeybee Kingdom! Our queen rules this land." In the final game, the bee says "Welcome to the Honeyhive Kingdom! Our queen rules this land."
 * Later, a different bee says "New Bees must greet the Queen Bee!" In the final game, she says "New Bees must greet Her Highness, Queen Bee!"
 * The Bee Mushroom has a slightly different design.
 * There is no music when Mario becomes Bee Mario for the first time.
 * The text box that informs players of Bee Mario's flying ability is a lighter shade of blue, and the font is different.

E for All
In what could be E for All, it was shown the Sweet Sweet Galaxy was originally called "Cookie Factory Galaxy" and "Rocky Road" was known as "Conquering the Sweet Cake".

Prima Guide
In all versions of the guide, readers are advised to look for a "unicorn-like horn" on the floor of the Bonefin Galaxy's main planet, since there is a red shell near it. The guide even shows a picture of the aforementioned. However, it is totally absent from the final game, suggesting that some modifications were made to the game even after it was given to the guide's writers.

Unused data
In the final build of Toy Time Galaxy, a train set is hidden beneath a platform in the first mission, probably because it is easier than just getting rid of it (although it could be an Easter egg).

HomePlanet, from the Star World, still exists in the game's code. The Star World itself has not been discovered, and is probably no longer accessible.

Some unused models were found in the game. These include the following: The low-polygon model for the house in Ghostly Galaxy has two chimneys that the high-polygon model lacks. Part of this model can be seen from the first Phantom Tower Planet in Beware of Bouldergeist by turning the camera around towards the mansion. If a player uses hacks to leave the cave in Deep Dark Galaxy's Purple Coin star, they will find that the objects outside the cave are mostly gone or misplaced. These oddities include:
 * A fake inflatable Toad balloon enemy.
 * Two different Bullies.
 * A blue and yellow genie's hand (much like Master Hand).
 * A Red Switch. Its filename is flagsaveswitch, suggesting that it was used as a checkpoint of some type.
 * Mario's model from Super Mario Sunshine. It only has his running, swimming, and waiting animations, meaning it may have been an early placeholder before Mario's Galaxy model was finished.
 * Also from Super Mario Sunshine is Peach's ponytail hair model which may have been a place holder for something else.
 * A creature composed of torimochi with a face.
 * Several leftovers from Donkey Kong Jungle Beat, including a Helper Monkey.
 * Ticojii, a character resembling Eldstar. Its name is probably a derived from the Japanese words チコ tiko, meaning "Luma" and お祖父さん ojīsan, meaning "grandfather" or "old man".
 * Onitsutsu, which would appear to be a type of Tox Box. It has the Japanese character 鬼 oni on one face , referring to the Oni from Japanese folk lore. The second half of its name is probably from the word 筒 tsutsu, meaning tube.
 * Billboarder, a small humanoid figure made out of flat circular textures with over fifty animations.
 * The model for the "fortress" from the Prima Guide's concept art page exists in the data, as well as the large Megaleg-like figure below it, which is known as "BossCrab".
 * "BossCrab" itself, a 4-legged version of what would become Megaleg; all of its animation exists.
 * A very early version of the note model with a wiggling animation.
 * DragonHeadFlower, a gigantic Piranha Plant-like enemy. It has animations for eating Mario/Luigi and spitting him back out.
 * A humanoid creature made of ice, called IceMan . It has animations such as AngryDemo and DeathDemo, indicating it was possibly some kind of boss. Also included is a model for the ice chunks that it would throw at the player.
 * The original purple version of the Slurple.
 * A large Piranha Plant given the nondescriptive name of "Octopus Queen".
 * OtaJack, a large green Octopus whose name indicates it is related to King Kaliente (known as OtaKing in the game's data). It has animations for waiting and being picked up. It also vaguely resembles Prince Pikante from the sequel.
 * A massive sand golem whose main model only contains skeleton and animation data, being built out of individual segments known as SandGolemBlock and SandGolemColumn.
 * TetuKuri, a shiny grey Goomba whose name translates to "Iron Goomba". It lacks animations for getting hit by a spin attack, indicating that it would be immune to it.
 * SpiderItemShell, a yellowish ball that opens up like the Party Ball from the Super Smash Bros. series. Its file name coincidentally relates to the Beady Long Legs from the Pikmin series, a spider-like creature whose head resembles and opens up like a Party Ball.
 * A set of various flying insects. The fact that the butterfly used in the game uses similar textures indicates that they were possibly intended for this game.
 * A robotic bee that has a propeller around its neck, similar to Choppahs from the sequel.
 * DummyNPC, a creature with a round, pink head and round, rainbow body.
 * Uminoko, a red creature which appears to be a species of Spiny, though the name more relates to Koopa Troopas.
 * An early model of a Red Star which resembles an ordinary Star more than a Pull Star
 * A placeholder design for a Bomp. Due to the file name, it seems it was intended to be a gigantic version of them, but the model itself is of the standard size.
 * Jiraira, a black landmine with a Bowser emblem on it. Like eyed Floating Mines, it too can regenerate after detonation.
 * An early model of Buoy Base Galaxy. It has more platforms than the final design.


 * The entire Toad Brigade is present, even though they are also in the cave with the purple coins.
 * Captain Toad is on the beach, and he says Banktoad's normal message ("Nope, I don't see any Purple Coin(s) hidden in the dirt.").
 * The Yellow Toad is also on the beach, standing on top of a blue structure only found on some levels in the Sea Slide Galaxy. He will create an empty text box if spoken to.
 * Banktoad is dancing where Hint Toad stood during star 2.
 * Hint Toad is inside the titular box of the "Boo in a Box" star. He floats above the ground and does not have glasses. If Mario gets too close to him, he will create an empty "small" text box.
 * Mailtoad is standing next to Captain Toad, and he gives his normal message for that star, which makes no sense when read out of context.
 * There is a green pipe on the beach next to Captain Toad and the Mailtoad. It is connected to another green pipe next to the Hint Toad. This could be an early route to the "Boo in a Box" star, or it could simply be an aid for testing.
 * Next to Banktoad there is a series of climbable poles. One of these is tilted at an odd angle an does not lead anywhere significant.
 * Also next to Banktoad is an Amp, not present in any other star.

Unused planets

 * Early in development, a planet known as "Starman Fort" was to be included in the game. The planet was composed of a large castle-like structure, as well as a construction zone and a snowy area .  The zone contained a boss that is referred to as "Boss Crab". It is thought that it is an early version of Megaleg.
 * An unused section of the Bubble Blast Galaxy contains cube bubbles. The only section of land is a small metal platform. The area is heat-based, and contains such obstacles as fireballs, wind, and steam. The level is designed in a maze format.
 * Buoy Base Galaxy's frame was different.
 * Bowser's Dark Matter Plant had two different blocks of dark matter.
 * If the Unactivated Megaleg "glitch" from the game is performed in Bowser Jr.'s Robot Reactor, a green and light brown planet can be seen if Mario/Luigi climbs to the top and enters first-person view. This is the grassy planet from the E3 demo before Megaleg.
