Super Mario Galaxy/Unused Planets

Bathtub Planet
A hemispherical planet sporting a basic checker texture and some water. The water uses the image of reflected clouds for its texture. It is quite large compared to Mario, coming in at 54m in diameter. According to the groupinfo, the water is hot.

Begoman Room Planet
An unused planet with a unique shape. The platform up top has a hole in it that drops down to the room below, with a partial ring. The name begoman is the internal name for Topman. The planet is 30m x 45m x 100.6m in the game's scale. According to its description in the object list, it was meant to be inside the main planet of Battlerock Galaxy.

Dossun Planet
An early version of the C-Shape Planet in Melty Molten Galaxy. The design has changed very little. (Dossun is the Japanese name for Thwomp.)

Flexible Sphere
Likely an early version of the multiple holey, hollow planets found in the game.

Floater Land Parts Frame
An early version of the final design for Buoy Base's frame. The final frame was eventually made part of the main planet model, cannons and all.

Jump Guard Room Planet
A room planet similar to BegomanRoomPlanet, with the name referencing the pink laser-ring-shooting, spring-loaded enemy found in various levels. Unlike BegomanRoomPlanet, not every wall has a modeled backside. It is probably an early version of one of the rooms in Battlerock Galaxy.

Onimasu Zone
A very early version of the Cyclone Stone in Beach Bowl Galaxy, found under the name OnimasuZoneGoalParts. Corresponding models for the other parts of the planet exist, though OnimasuZoneStartParts has been wiped. The dark blue squares indicate the safe zones from the rolling boxes.

Rock Entrance
An early version of the entrance to the interior of the Battlerock, named RockEntrancePlanet.

Space Junk Grave Stones


Along with the other files for the path to Tarantox in Space Junk Galaxy, these two planetoids didn't make it to the final stage. GraveStoneD is a simple L-Block like GraveStoneC, while GraveStoneE is a small rocky ball. Unlike the other planets in this category, these objects have a proper texture.

Unfinished Planets
Some planets only have placeholder models, as they were never finished before being cut from the game. Planets that use the Temporary High Model placeholder include BigRelayPlanetB, HiTowerGoalPlanet, HiTowerGoalPlanetLow, OceanOnimasuPlanet, OctopusTrapPlanet, PhantomCavePlanet, SeaStormPlanet, WaterTransparentPlanet, and WaterTransparentPlanetLow. Planets that use the Temporary Low Model include OceanOnimasuPlanetLow, OctopusTrapPlanetLow, PhantomCavePlanetLow, SeaStormPlanetLow, and TwinPeanutsPlanetBLow. Ironically, the low model placeholder is much larger and has way more polygons than the one for high models.

Asteroid Cluster A


While not exactly planets, this belongs with them. This cluster of giant asteroids are shaded in such a way that indicate a bright light source was in the center of them. They have no collision data, and no low-poly version.

Boss Planet
A battle arena filled with generic planet spheres and rings of clouds, all orbiting around a large central planet. The featureless central planet has a diameter of 150m and matches perfectly with curvature of BossCrab's feet when animated. One of the planets in the background has an image imitating a Power Star indicator shine.

Exterminate Burn Bit Planet
A planet in the style of Melty Molten Galaxy planets, but with a lower polygon count. Meramera is the name for Burn Bit.

Flag Disk C
A planet very much like the first disk in the set of three found in Gusty Garden Galaxy, with the exception of a giant arrow sign on top.

Glassy Twins
A pair of planets from the original E3 demo. The grassier of the two twins has a distinct rocky ring pattern. The planets shown are actually two separate models.

Home Planet
This egg laden planet was once used in the Super Mario Galaxy E3 demo and officially released to the public in the form of screenshots. Unfortunately, it was removed from use in the final build, with only its model left within the game's file system as HomePlanet, with a copy under WorldMapHome. Low-poly versions of this planet exist as well, under the names HomePlanetLow and AstroDomeDemoHomePlanet. Astro Dome refers to the Comet Observatory.

Normal Galaxy
A very plain sphere with a mildly sandy texture. It has two related files named normalspheretest. It also comes with two normal maps, low-resolution and 512x512.

Ocean J-Shape Planet
A near-perfect copy of the planet from Melty Molten Galaxy, but with water instead of lava and different textures.

Planet Disk
A planet with its own clouds and sun. It has a flower patch on the top side, along with some mushrooms and a large picture of tree leaves. Interestingly, a sketch of this planet shows up in the concept art for the Starman Fortress.

Pole Unizo Land Planet
A strange rocky planet with a name referring to the fuzzy red Urchins found in hot galaxies. It has a low model, but it is identical. Unlike the other unused planets, this one has an entire unused zone dedicated to it.

Star Planet
A big textureless star shape with exactly 1000 polygons. It does have a collision version. Several instances of this planet also appear in the Starman Fortress concept art.

Starman Fort
A high-quality planet that was ultimately scrapped, much to the dismay of the development team. The two pipes on the planet are not warps but instead have the fully modeled tube interior, with the second pipe leading from the top of the tallest roof to the spherical underside of the planet. The yellow structure bears the same electric symbol as the ChargeSpot model. It, too, has concept art in the Prima guide. As can be seen by the concept art, it went through several incarnations, with the last two being left in the game files. The version seen in the concept art depicts features such as a snowy area and a construction site. It's also interesting to note that this same image also shows BossCrab, Planet Disk, and three copies of the Star Planet. It also shows some generic spherical planets and the space ship planet used in Space Junk Galaxy.

Relay Planet C
A small planet found in the E3 demo of the game, but nowhere in the final. It was located at the alternate branch of the pull star path.

Relay Planet F
A very rusty and unused planet. It has a low-poly version as well. This planet technically is used, but only shrunken down and as a decoration on the way to the electric Undergrunt Gunner in Toytime Galaxy.

Relay Planet H
A planet very similar to the metal planets in Gateway Galaxy. It has a place on one end for a cannon or similar square object.

Star Dust Hill Planet
A small hemisphere planet bearing the name for Space Junk Galaxy. Despite this, it is featured in the level selection model for Good Egg Galaxy.

Star Dust Star
A strange planet with weird-shaped hills. On the opposite side of the Question Mark hill is a heart shape. Once again, it bears the name of Space Junk Galaxy, but would fit better in Good Egg Galaxy.

Takohei Relay Planet
The name Takohei refers to the red octopus enemy, Octoguy. The reflection image used on the metal is the same one used by UFOs and other models in the final version of the game.

UFO Blue Star Cupsule
A UFO combined with the standard Pull Star capsule planet. The most interesting feature is that all of its textures are slight variations of the ones used by other UFO models, including two recolored environment images. The spelling error is indeed part of the name.
