Good Egg Galaxy

The Good Egg Galaxy is the second galaxy Mario must venture to in Super Mario Galaxy. It is the first galaxy within the Terrace dome. It is a galaxy which, unlike many of the others in the game, does not have a set theme such as ice or fire. Rather, it mainly consists of multiple small planetoids and a variety of different themes that usually contradict each other. Because of this, it is arguably the most 'true' galaxy with a pure space theme. The galaxy starts on a planet with a garden and a house on top and a castle at the bottom. Dino Piranha and King Kaliente are fought in this galaxy.

Starting Planet
The Starting Planet has two sides. One is green with a house on it and two groups of flowers where the player can get Star Bits. This side has some Electrogoombas, with Coins and Star Bits in the little bushes. It also an orange pipe on the roof of the house, which will lead the player inside of it. In here, the player will find four yellow circles which will make a coin come out of it if a Star Bit is shot at the yellow circle. In the center of these four circles, a ? Coin that will make Rainbow Notes appear will be here. The underground theme from Super Mario Bros. will play if the player collects these Rainbow Notes. A 1-Up Mushroom will be awarded to the player if they collect all the notes on time. The other side is dark and has a tower on it, with an orange pipe that will lead the player into the house on the brighter side, a green pipe which will also lead the player to the other side, as well as many Star Bits and coins scattered everywhere on the dark side of the planet, and the dry trees which are also on the darker side too. This is arguably the best place to get Star Bits in A Snack of Cosmic Proportion.

Boulder Planet
This is a yellow planet that resembles a peanut with little grooves where the boulders have been rolling. It has 6 boulders that Mario must dodge and/or break by using his Spin. To access a Launch Star, Mario must get the five Star Chips here while avoiding the Boulders. The mud will also slow Mario down, making him vulnerable to damage. It has a different color appearance when it is first seen, but it ends up appearing with a recolor in the final version of the game. It was originally supposed to be blue.

Flatland Planet
The Flatland Planet has a Piranha Plant which will sprout a vine when defeated. It will also have some Swoopin' Poinks that will try and suck the player's health. Also, on the other side of this planet is a ? Coin., which will make Star Bits appear in a trail leading to the Piranha Plant, and will be in the shape of the vine that will come out once the Piranha Plant is defeated.

Bitten Apple Planet
This 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. There is a black hole in the middle of this planet. If the player chooses to go right, they can access the Flip Switch Planet. Coins will be placed at area where the boulders won't roll to, and some Swoopin' Poinks will be around this planet. The purple Piranha Plant can be defeated by either Jumping or Ground-Pounding it's head, or by using a Spin on the Rubber Ball to make it stretch out and hit the Piranha Plant.

Flip Switch Planet
A planet covered in Flipswitches. It can be accesed when the player goes to the right of the Bitten Apple planet, and defeats the Piranha Plant inside the pipe. The player will have to activate all the Flip Switches to move on to the next part of the planet. If the player falls off of a Flip Switch, they will be sucked into the black hole. If the player completes the planet by activating all the switches, they will get a 1-Up Mushroom.

Block-Climb Planet
After the player launches off the Bitten Apple Planet, they will be in the Block-Climb Planet. This planet will have some Electrogoombas, a Luma, and a Starbag. There is nothing on this planet except for the enemies, a 1-up mushroom behind the blocks, and coins scattered on top of blocks and platforms. A Launch Star is at the bottom of it, which will take the player to the Geo Planet.

Geo Planet
The Geo Planet is a small planet where the Dino Piranha boss is fought. It is made of gravel and rock with patches of grass sticking out, much like a simple ball of earth mixed up together. There are Item Crystals on it with a few Coins and Star Bits inside of them. Once Dino Piranha is defeated, the player will be awarded with a Power Star.

Pear Planet
This Pear-shaped Planet has a few Goombas on it and a Launch Star that will take the player to the Rock Planet. There are also some spikes on the Pear Planet, and a few Item Crystals. Using several methods (spikes, item crystal, launch-throughs) the player can obtain 100 Star Bits on just the Starting Planet and Pear Planet.

Rock Planet
This planet is a rock with boulders moving all around it. The rock planet also has more Item Crystals, a ? block, and a Launch Star that will take Mario to the Egg Planet. There is also a Sling Star here that Mario can use to reach a coin.

Egg Planet
This planet resembles a Yoshi Egg. This planet can only be found in two levels, which are "A Snack of Cosmic Proportions", and "Purple Coin Omelet". The Egg Planet will have Item Crystals which will contain Star Bits. Also, many Goombas will wander the planet too.

Tower Planet
This planet requires jumping up cliffs to reach the top. It is full of Spiny and Round Bushes and only appears after the Hungry Luma is fed 100 Star Bits.

Pill Planet
The Pill Planet is shaped like a giant, transparent pill. It contains many obstacles and items, mainly Coins and Item Crystals. Atop the towering planet is a Launch Star that Mario can use to break out of the Pill Planet's glassy surface. This planet contains a 2D platforming area with variable gravity.

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 Star Planet or Mario can simply Long Jump to the Star.

Tropic Planets
A pair of planets in Star 3, both involving coconuts. The first planet has some spiky plants, and Mario has to destroy the larger one to get to the next planet. A Sling Star appears and takes Mario to the second, which has a Pokey on the top as well as Goombas. When it surfaces, Mario kicks a coconut at it and finds a Launch Star. Both planets have crates and palm trees.

Water Planets
These are small planet that surround the tropic planets. They are either completely water or have a small sand core. They are unaccessable and the player only sees them when Mario soars past them. But, through hacking the player can visit them. These act like a regular planet because they have their own gravity field.

Saucer Planet
The Saucer Planet has Yellow blocks on it, some Electrogoombas, Chomps, and Bill Blasters. To get the Launch Star, Mario must avoid the enemies and go to the top of the planet, right above the Bill Blasters, and destroy the Item Crystal. This takes him to the Airships.

Airships
There are two airships here, both commanded by King Kaliente. To get to the second one, Mario must wait until the enemies on the airship throw coconuts at him. Then, the player must Star-Spin the coconuts back at them to defeat them and to open the bridge. The second airship has many Electrogoombas and a Launch Star to the Magma Planet.

Asteroid Planet
A planet before the Magma Planet or the Airships. There are two Chomps going around it. The player can go inside the pipe here, which will lead them to a small circular room with several Goombas and a ? Coin which will make a Rainbow Star appear.

Magma Planet
This is where the boss battle against King Kaliente takes place. It consists of a hot lava pool with a shiny tar-like ring of ground around it. The rest of the planet is just simple hot rock. The planet is quite big compared to others like the Tropic Planet, 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. It resembles a chocolate donut.

Dino Piranha
This level begins on the starting planet with a grassy top and a house. There are two Electrogoombas guarding the door to the house (which does not open). The gravity on the starting planet is such that Mario cannot fall off so he can just walk over to the other side where it is all dark with a castle-like object. Mario must climb up the tower on a pathway, avoid the Goomba and talk to the Luma to get a Launch Star. The next planet is the Boulder Planet, it has five Star Chips scattered around it, Mario must collect them all, while avoiding the Boulders to get another Launch Star. The boulders are going around in rings and most of the parts that they roll over are made of mud. The five stars lead Mario to the next planet, the flatland planet, where Mario must Star Spin the Piranha Plant after it strikes at him for it to release a sproutle. Next up is the bitten apple planet where Mario has a choice as to where he wants to go. The first option is to defeat a huge piranha plant then spin on the sproutle's vine or he can defeat the small piranha plant and release a Warp Pipe which leads to the Flip Switch Planet. On the flip switch planet, Mario must press all the blocks to obtain get a Launch Star which will bring him to the Block-Climb Planet (this is where the sproutle's vine would of brought him). To get to the top of the Block-Climb planet, Mario must climb the stones to the top which have Electrogoombas on the them. At the top of that planet there is a launch star which leads to the Geo Planet.

The Geo Planet is where Dino Piranha is fought, Mario will land on a gigantic egg which will then crack, releasing the prehistoric beast! To open the egg fully, Mario must star spin the tail which will fly back and crack the egg. Dino Piranha will then run after Mario and Mario must once again star spin the tail to hit it. The flower at the top of its body will turn red and it will charge extremely fast at Mario, if he manages to star spin the tail one more time, Dino Piranha will fall over and release a Power Star.

A Snack of Cosmic Proportions
This level revolves around feeding a Hungry Luma one hundred Star Bits, so the player should pick up as many as possible. Mario begins on the Starting Planet with two Electrogoombas. There are constant comets on this planet and several star bits, the comets release about three star bits each. To complete this planet, Mario must travel to the end of a stone path where there is a blue Luma who will turn into a set of Pull Stars which lead to a Launch Star. The launch star sends Mario into a 3-planet circle with a maze of launch stars in midair the planets are the Jungle Planets and the Egg Planet. The Egg Planet has the Hungry Luma but Mario must use the other two planets for star bits. When the Luma is fed, it will burst with snacky happiness creating the Tower Planet. Mario must climb this planet to the top to reach another launch star which will launch Mario straight to the Pill Planet. There is a crystal covering the entrance to the inside of the pill planet so Mario must smash it to get inside.

The inside is a 2D platform area which Mario must navigate very carefully as there are constant gravity shifts. Blue Arrows mean the gravity is pulling down and red arrows mean the gravity is pulling up. Avoid the shifting gravity and get to the Launch Star which will blast Mario through the glass and to the Star Planet which has five blue Star Chips that create five pull stars which Mario must use to get the Power Star in the very middle of the planet. Another option is to long jump to the power star.

King Kaliente's Battle Fleet
Mario starts on the same planet as he did on the previous two missions. The Launch Star is on the top of the house on the Starting Planet and it is possible for the player to triple jump to the top of it, or else Mario can take the orange Warp Pipe on the underside of the planet and traverse the boxy room to reach the Launch Star. Next up are the Tropic Planets. The Toad on one of the planets tells Mario that the spiky plants hate coconuts. Mario will have to kick the coconuts into the plants, and one will reveal a Sling Star. The next tropic planet has a large Pokey, which can also be defeated by kicking a coconut at it, revealing a Launch Star. Then there's the Saucer Planet which has a Sling Star which propels Mario to a planet full of electrical walls, but if the player decides to stay on the planet they can enter a pipe to an area with a Rainbow Star and lots of Goombas. The player must carefully avoid the walls of the next planet to reach the other side of the planet, where cannons shoot Bullet Bills. The Launch Star is in a crystal at the top of the structure on this planet. As Mario is launched onto an airship, two creatures will shoot coconuts at Mario from an adjacent airship. Mario will have to do a Spin to send the coconuts back at them to defeat them, which lowers the bridge between the two ships. The Launch Star on this airship that takes Mario to King Kaliente's planet. The player can defeat King Kaliente by repeatedly spinning back the coconuts he shoots at Mario.

Purple Coin Omelet (Purple Comet)
In this level, the player has to collect 100 purple coins to get the Power Star in the area of the three planets before the tablet-like planet in the 'Snack of Cosmic Portportions'with out the Hungry Luma planet. Mario must traverse through the galaxy and collect these coins using launch stars. Unlike most other Purple Comet missions (with the exception of Purple Coins in the Woods), the coins here follow a linear path - simply follow the trail of coins on the first planet, take the Launch Star, take the Launch Star in midair on the way, follow the path of coins on the second planet, etc. If the player repeats this process a few times, they will have collected every coin and will land right next to the Power Star.

Luigi on the Roof
Shortly after Mario rescues his brother Luigi in the first mission of the Ghostly Galaxy, Mailtoad will inform Mario that Luigi has sent him a letter saying he is lost, with an enclosed picture of his whereabouts. The player can work out that Luigi is in the Good Egg Galaxy. To clear this hidden Star mission, the player must enter the mission Dino Piranha (after receiving the aforementioned letter) and reach the top of the mushroom hut on the first planet. The easiest method of reaching the top is simply doing a Triple Jump and Spin on top of it, but another way is to walk around to the underside of the planet and enter the orange Warp Pipe there. After traversing the room, possibly gaining a 1-up from collecting Music Notes, the player can jump through another orange Pipe and emerge on the top of the Hut. Luigi will give Mario the Star and the mission will be completed.
