Good Egg Galaxy

Good Egg Galaxy (originally known as Egg Planet Galaxy) is the second galaxy in Super Mario Galaxy. It is the first level within the Terrace dome. Good Egg Galaxy is one of the few galaxies with no set theme that continues to be visible throughout the planets. It has different planets with many contradictory themes, much like a true galaxy. However, most of the planets are lush and grassy, and some resemble food. Dino Piranha and King Kaliente are the bosses here. Good Egg Galaxy has the most planets out of any other one between the two games, having 19 planets total. The name of this galaxy is most likely a pun on "good egg", which means a reliable and pleasant person. The game cover of Super Mario Galaxy features five planets from this galaxy.

The original E3 demo and gameplay footage mostly featured segments from Good Egg Galaxy, along with a mixed-in level from Space Junk Galaxy. Good Egg went through a few revisions before its final version, mostly involving planets getting redesigned or removed, as seen in the GDC 2007 Trailer.

Planets
NOTE: Unless otherwise noted, all names are unofficial.

Starting planet
The starting planet is multi-sided; there is a light side and a dark side. On the light side there is grass and bushes with Star Bits and Coins hidden in them. There is also a house with a tree on the right and two Electrogoombas guarding the front. There are two bridges, one on each side, that lead to the dark side of the planet. Inside the house there is a ? Coin which releases several notes that will play the underground theme from Super Mario Bros. while Mario collects them. After getting them all, a 1-Up Mushroom will appear.

The darker side of the planet has many dead trees with Star Bits on their branches and a constant rain of them coming down from above which makes it, arguably, the best location to get Star Bits in the galaxy. In the center of the planet there is a giant tower with a special side that bends the laws of gravity and allows Mario to walk up. There is an Electrogoomba guarding that side.

In the levels there will be Launch Stars placed in three different locations; where the launch star is depends on the level. In the missions "Dino Piranha", "Dino Piranha Speed Run" and "Luigi on the Roof" it can be found at the top of the tower and leads to the Boulder planet, though in "Luigi on the Roof", Luigi is located on top of the house, so there is no point in taking the Launch Star. In "A Snack of Cosmic Proportions" and "Purple Coin Omelet", the Launch Star is located at the top of a set of three Pull Stars at the end of a stone walkway next to the tower and leads to a maze of three planets; the Tropic planets and the Egg planet. Finally, in "King Kaliente's Battle Fleet", the Launch Star is on top of the house and leads to the Tropic planets.

In early versions of the game, the planet looked drastically different. It had a more realistic house, a pine tree instead of a regular tree, and no stairwell leading up to the twisty walkway.

Boulder planet
The Boulder planet is a Peanut shaped planet with lots of mud and Boulders in "Dino Piranha" and "Luigi on the Roof". However, in "Dino Piranha Speed Run", they are replaced by Chomps. Mario can either dodge or destroy the Boulders with his Star Spin, but he cannot hurt the Chomps.

To get here, Mario must take a launch star from the starting planet and the only way to leave is to get the five Star Chips and create a Launch Star that takes Mario to the Bean planet.

This planet had a different color appearance when it was first seen, but it ends up appearing with a recolor in the final version of the game. It was originally supposed to be blue.

Bean planet
This is a small, grassy planet with one Piranha Plant and a few Slurples as its only dangers because it is impossible to fall off this planet due to the gravity. On the bottom side of the planet there is a ? Coin which creates many Star Bits leading back to the Piranha Plant.

Mario will get here via a Launch Star from the Boulder planet and then, to leave, he will have to stomp or spin the Piranha Plant to defeat it. After being defeated, the Piranha Plant will release a Sproutle Vine for Mario to climb to get to the Bitten Apple planet.

Many planets similar to this one can be found in other galaxies and in early versions of the game.

Bitten Apple planet
The Bitten Apple planet, as its name states, resembles a green bitten apple. There are Boulders rolling all over the planet, and a large purple Piranha Plant on the top. In "Dino Piranha Speed Run" the Boulders are replaced with Chomps. There is a black hole in the middle of this planet which will make Mario lose a life if he falls in. Also, if Mario stands on one of the bridges on the starting planet on the light side, he can see the Bitten Apple Planet and the Flipswitch Planet. If Mario turns to a certain angle he can see a pipe but oddly, if he turns the other way, it disappears.

On this planet Mario has two choices as to where he wants to go. The first choice is to advance to the very end of the planet and battle a Spiny Piranha Plant which will release a Sproutle Vine to the Block-Climb planet. The other choice is to go across a shrinking platform and using the Warp Pipe with the Piranha Plant in it to get to the Flipswitch planet.

Flipswitch planet
The Flipswitch planet is a planet covered in Flipswitch Panels. It also has a few red platforms with spikes on the sides that can hurt Mario, but that he can also use to carry him across the planet. It can be accessed via a semi-hidden Warp Pipe from the Bitten Apple planet. In order for the player to continue, he must press all the Flipswitch Panels in the first area before the ones in the second area will appear. After activating all of them, a Launch Star leading to the Block-Climb planet will appear. It also plays the Space Fantasy music when Mario is here.

Block-Climb planet
The Block-Climb planet is a planet accessed by either launching off of the Flipswitch planet and landing here or taking the Sproutle Vine that comes out of the purple Piranha Plant on the Bitten Apple planet. This planet is a grassy oval with three stone blocks on it and Electrogoombas guarding them. There are some coins on them which serve as steps to the very top where a Launch Star is waiting to take Mario to the Dino-Geo planet. Behind the set of three stone steps, there is a 1-Up Mushroom to give Mario an extra life. Also on the planet are a Luma and several Petapeta.

Dino Geo planet
The Dino Geo planet is a small round planet that is the last planet visited in the levels "Dino Piranha" and "Dino Piranha Speed Run" as it is the location of the boss in those levels: Dino Piranha.

The planet is basically a large brown oval with several yellow objects on the ground that, when shot with a star bit, will release a coin, and several Crystals with coins and star bits in them. On top of the planet is a giant egg that Mario will automatically crack open when he lands. Dino Piranha hatches, and the Boss Battle starts. After defeating Dino Piranha, the Power Star appears here. A similar planet appears in Super Mario Galaxy 2, in the Boss Blitz Galaxy. On that planet, Dino Piranha is fought once again as a returning boss.

Super Mario Galaxy trading card description
''Landing on this planet seems unevental. That is, until Mario makes his way to the other side. He spies a giant walking egg with a tail sticking out-definitely something to be investigated. Spin Mario against the large ball on the end of the tail to crack open the shell. Out bursts Dino Piranha - the boss of this world, who Mario must battle to gain the first Power Star in the Good Egg Galaxy.''

Pear planet
The Pear planet is a pear-shaped planet covered in grass that appears in "A Snack of Cosmic Proportions" and "Purple Coin Omelet". There are several Star Bits in the Crystals all over the planet along with a few Goombas and thorny flowers. There is also a Launch Star to the Rock planet here.

Rock planet
The Rock planet is a giant red rock with Boulders rolling all over it. It is accessible via the Pear planet. The Launch Star on this planet takes Mario to the Egg planet. The Rock planet also has some Crystals and a ? Block. There is also a Sling Star that can launch Mario into a coin.

Egg planet
The Egg planet is a planet that resembles a giant Yoshi Egg with many Goombas wandering all over. Also, there are several Crystals. It is part of the three-planet maze involving the Rock planet and Pear planet. The Launch Star on this planet leads to the Pear planet and it is accessible from the Launch Star on the Rock planet.

The main attraction of this planet is the Hungry Luma that must be fed 100 Star Bits to transform into the new planet that is needed to complete the level; the Tower planet.

Tower planet
The Tower planet is a planet made by a Hungry Luma on the Egg planet and is shaped like a giant mountain with many stone platforms on the other side that can help Mario jump up to get to the top. Enemies found here are mostly thorny flowers and Goombas. The flowers can be defeated by the rubbery bulbs. At the very top of the many stone platforms is a Launch Star to the Pill planet.

An almost identical planet with the same name appears in the Yoshi Star Galaxy in Super Mario Galaxy 2, the only differences being that the planet in that galaxy is already present, while the planet in the Good Egg Galaxy is formed by a Hungry Luma and there are bones on the planet in the second game. When Mario is very far from the planet, it appears as a different low-poly egg-shaped planet, which was likely originally in place of the Tower Planet before getting added. This is likely because a low-poly model of the tower planet was not made at the time, but one was eventually made for Super Mario Galaxy 2.

Pill planet
The Pill planet is the biggest planet in the Good Egg Galaxy. It is shaped like a giant transparent pill with many enemies and obstacles on the inside including different sections where the gravity is shifted around; red means it goes away from the core, blue means it goes towards it. It resembles a Megavitamin.

When he first arrives here, Mario will be on the transparent coating of the planet from the Launch Star on the Tower planet and he will have to destroy the Crystal to get inside. After making his way through all the obstacles, another Launch Star will blast him right through the glass and to the final planet of the mission; the Star planet.

Star planet
The last planet of the second mission, which resembles a Sling Star. To get to the star, the player must collect Blue Star Chips to create some Pull Stars. Mario must then use the Pull Stars to get to the Power Star in the center of the Planet or he can simply Long Jump and Spin to get to the Star.

Tropic planets
The Tropic planets are a pair of planets with thorny flowers and Coconuts that can be put to different uses depending on which planet Mario is on. The planets are made up of a combination of sand and grass with scattered palm trees and crates everywhere. On the first planet there are multiple thorny flowers which Mario can destroy with a coconut, but to access the next planet, he must destroy the extremely large thorny flower at the top to make a Sling Star appear. The second Tropic planet has several Goombas and a Big Pokey. When the Big Pokey comes to the surface, Mario must hit its head with a coconut or hit its body, which will destroy a body segment and lower its head closer to the ground. After doing this a Launch Star will appear to send Mario off to the Chomp Saucer planet. The first Tropic planet is accessed by blasting off the Starting Planet in "King Kaliente's Battle Fleet".

Water planets
The water planets are small rocks in the sky surrounded by water which float all around the Tropic planets. They are inaccessible during the regular levels, but, through hacking, Mario can visit them as they have their own gravity field. Other than that, they are mostly for ambience while Mario soars past them on his way to the Chomp Saucer planet.

Asteroid planet
The Asteroid planet is a small, optional, planet accessible from the Chomp Saucer planet with two Chain Chomps rolling around it. The only thing here is a warp pipe which leads to the inside; a room with many Goombas and a Rainbow Star to help Mario defeat them and receive many Star Bits. In the early version of the game, there were several planets like this one.

Chomp Saucer planet
The Chomp Saucer planet is a large grass-covered planet that is accessed from the Tropic planets and has a Crystal containing a Launch Star at the very end of it that leads to the airships. Enemies on this planet include Electrogoombas, Bill Blasters, Chomps in two sizes, Amps and Burners who make the planet much more difficult to cross. Probably the most notable difficulties on the planet are the electric barriers placed throughout that Mario has to cross. Once Mario finally reaches the end the Launch Star will take him to King Kaliente's fleet.

Super Mario Galaxy trading card description
''Once Mario gets to the top of this planet in the Good Egg Galaxy, he finds it is littered with half-buried blocks. It's tempting to climb up to grab all the coins, but if he does, he becomes visible to his enemies. Mario needs to focus on the Launch Star, which is located on top of the Bullet Bill cannons and protected by Electrogoombas. Mario must spin them away to claim the prize.''

Octopus airships
There are two airships floating in space which are both commanded by King Kaliente and have many enemies on them. The first airship is able to be accessed from the Launch Star on the Chomp Saucer planet and has two Octopuses firing coconuts at it from the second ship. If Mario defeats them both, the the bridge is opened.

At the end of the bridge there is a Sling Star that leads up into the main section of the ship where several Electrogoombas will attack. If Mario takes the Launch Star located on this ship he will travel to the Octo Magma planet where he will battle the commander of both airships; King Kaliente.

Octo Magma planet
The Octo Magma planet is an extremely large stone planet with a pool of lava in the middle which is home to the boss of the level "King Kaliente's Battle Fleet", King Kaliente. This is the location of the King's boss battle as he emerges from the lava and fires coconuts and fireballs at Mario.

The planet is mostly made up of black tar and rock mixed together by the gigantic pool of hot lava in the middle. The rest of the planet is just simple hot rock. This planet is quite big compared to others like the Tropic planets, since it needs to have a decently large size for the fight to be held. Underneath the Magma planet is a rocky area with yellow rings on it like a target which resembles a chocolate donut. During missions in which the planet isn't normally visited, it is drained of its lava.

Mario & Sonic at the Olympic Winter Games
Good Egg Galaxy appears as the location for both the Individual and Team versions of the Dream Event Dream Ski Jumping in the Wii version of Mario & Sonic at the Olympic Winter Games. It features airships, the starting planet, three Star planets, blue crystals and the water planets as obstacles that can be collided with, and a black hole as a hazard when characters fall off the landing platform. The course also features Star Bits that when collected award the player points, Balloons that the player can collect items from, Bonus panels that can be collected to double the player's score and star lines that allow them to travel faster.

Fortune Street
The Good Egg Galaxy appears as one of the boards for the Mario franchise in the game Fortune Street. Elements from the Galaxy are seen throughout the board, while the board itself is looped around the Pill planet.

Mario Golf: World Tour / Mario Sports Superstars
A few planets of the Good Egg Galaxy appear in Mario Golf: World Tour, as well as Mario Sports Superstars, in Rosalina's Eagle, Albatross, and Hole-in-One animations.

Music
This galaxy's theme plays in the Grandmaster Galaxy mission "The Perfect Run" from Super Mario Galaxy 2, along with Gusty Garden Galaxy's theme, Bowser's Galaxy Reactor's theme, and the Comet Observatory theme. A cover of the music can also be found in World 1's map after Green Star comets appear. Part of Good Egg Galaxy's music returns in Mario Kart Wii's Rainbow Road music. A remix of Good Egg Galaxy's music appears as one of the selectable songs that can be played during events in Mario & Sonic at the Sochi 2014 Olympic Winter Games. Part of the music plays while Mario and Princess Peach are whisked away with the final Grand Star.

Trivia

 * Good Egg Galaxy's level select model has a hemispherical grassy dirt planet that is not found anywhere in the galaxy.
 * On some planets, such as the Chomp Saucer Planet, a multicolored cube planet can be seen in the distance out in space. It is actually the location in which the orange Warp Pipes on the Starting Planet lead to. An identical planet is visible in the Deep Dark Galaxy, while a similar spherical planet can be seen in the Toy Time Galaxy.
 * Gusty Garden Galaxy originally had Good Egg Galaxy's background.
