Yoshi Star Galaxy

Yoshi Star Galaxy is one of the many galaxies in the game Super Mario Galaxy 2. This is the first galaxy in which Yoshi is found, however, before Mario can break Yoshi's Egg, he must defeat a Magikoopa to break the barrier surrounding the egg. The galaxy itself consists of lush meadows, with many flowers, grassy paths and an active volcano.

The player will land at the beginning of a path. The pathway ahead of the start goes uphill, dominated with Piranha Plants, Electrogoombas and Spiky Plants. Ahead after the pathway, there is a force field around a Yoshi Egg on a nest guarded by a Magikoopa. After it is defeated, the force field disappears and the Yoshi Egg can be cracked open to release Yoshi. Just up ahead of the egg's nest are some Berries and enemies that Yoshi can eat for Star Bits. To the left of the berries is a small hill with a Comet Medal on top. There is a small waterfall with a rushing current nearby as well. To the right are several terraces of land which contain Item Crystals and Flipbugs. There is also a huge volcano, where the player and Yoshi find the Launch Star, after a giant golden berry is eaten by Yoshi. In the second mission, the majority of this area is infested with Lakitus and a whole mess of Spinies.

After using the Launch Star from the first planet, Mario and Yoshi land on a tiny planet, where they can pass by a Midway Point. It has Item Crystals, insects, and a Chance Cube. One of the crystals reveals a Launch Star, which Mario must take to travel to the next planet.

In this planet, the player and Yoshi must climb up the tall planet to reach the Launch Star. There are Piranha Plants and Spiky Plants which cover up most of the pathways, but fortunately, Yoshi can dispose of them by eating them. At the top, there are Electrogoombas and a flower grapple. Using his tongue, Yoshi can swing up to a tiny wooden orb with the Launch Star. This planet is almost physically identical to the Tower Planet in the Good Egg Galaxy in the first game, exepct for a bone-like platform at the bottom and a few blue springboards. This planet is also one of three planets that appear on the cover of Super Mario Galaxy 2.

After using the Launch Star from the Yoshi Tower Planet, the player and Yoshi will arrive on this large planet. There is a Midway Point in front of where the player and Yoshi landed. This planet is infested with Scuttlebugs and Paragoombas, both of which can be a nuisance at some points. The player and Yoshi can navigate through the planet by jumping between the blocks, using the flower grapples, pulling moveable blocks, and using the moving platforms. By using the flower grapples, the player and Yoshi can reach the top area where the Power Star is trapped in crystal.

During the second mission, the player and Yoshi will land on this planet after using the Launch Star from the main planet. Here, they can pass a Checkpoint Flag. Enemies here include a Lakitu and several Spinies which the Lakitu spawns. There are also three cages, two of them containing Star Bits, and the other containing a Luma which will transform into a Launch Star once it is set free. The cages can only be broken by having Yoshi eating and spitting out a Spiny towards one of the cages.

During the second mission, Mario and Yoshi can land on this planet when using the Launch Star in midair after beginning to blast off from the Central Shape Planet. This area has a set of small, flat planetoids that are orbiting around a slightly larger spherical planet. These platforms contain a 1-Up Mushroom, a Life Mushroom, a few Coins and some Berries. Mario and Yoshi can use the Launch Star on the planetoid located at the top to blast off to the next planet.

During the second mission, the player will land on this planet where they must use Yoshi's tongue to pull out platforms to climb up. The player must also have Yoshi eat a Spiny and spit it out toward a cage with Launch Star inside to blast off to the final planet. Enemies here include a Lakitu and Spinies. There are also Item Crystals containing Star Bits and a coin and the platforms that Yoshi can pull out contain a 1-Up Mushroom, Coins, and Star Bits.

This is the final planet during the second mission. The player and Yoshi will land on this area after blasting off from the Marble Block Planet. Here, they can pass a Checkpoint Flag. Using Yoshi's tongue, they can swing up to the top area where Giga Lakitu is fought on. There are two Item Crystals on this planet, each with a Coin inside of them.

Saddle Up with Yoshi
The player begins the level on the Main Planet where there is a Yoshi Egg being protected by a barrier created by a nearby Magikoopa. The Magikoopa summons Goombas to fight the player. They must simply defeat the Magikoopa to be rid of the Goombas and destroy the barrier guarding the egg. After breaking the Yoshi Egg, Yoshi will pop out. The player must use Yoshi to get through the Main Planet. There are tons of things to eat around the main planet. After clearing out the area, the player must travel through the muddy path leading away from the main area of the planet until they gets to a golden Berry. Yoshi must eat the berry to make a Launch Star appear leading off to the Earth Planet. The Earth Planet is covered in crystals, has a Midway Point and a Chance Cube. The player should break open one of the crystals to reveal a Launch Star, which transports the player to the Tower Planet. The Tower Planet has a path that winds up one of the big mountains, which Yoshi and the player must go up, eating or hopping over all roadblocks on the way.

Once at the top there will be a single Flower Grapple. Using Yoshi's tongue, the player must use the grapple to reach the small planet with a Launch Star. This Star takes the player to the Fossil Planet. On the Fossil Planet, there will be numerous things like drawers for Yoshi to pull open, Flower Grapples, enemies such as Scuttlebugs and Paragoombas, and moving platforms. Mario must travel through the only path to get to the top and reach the crystal containing the Power Star sealed inside. After breaking the crystal, the player will need to use the Flower Grapples to reach it.

Spiny Control
After visiting the galaxy for the second time, the player will find the Starting Planet, along with others, infested with Spinies and Lakitus. The Starting Planet is also littered with cages containing different items, such as Star Bits, 1-Up Mushrooms, and even the teleporter to the bonus planet. The player needs to bust open the cage containing the Launch Star, though. On the Central Shape Planet, the player will need to use Yoshi to eat a Spiny and spit it at the cage with the Luma. The Luma will transform into a Launch Star. During the flight, the player can either take the Launch Star in midair to the Solar System Planet or simply go to the Marble Block Planet.

After reaching the top of the Marble Block Planet and breaking the cage, the player can reach the final planet. On this planet, the player will face Giga Lakitu. After he has been defeated, the player can take the Power Star.

Trivia

 * The Tower Planet is actually a return planet from Super Mario Galaxy in Good Egg Galaxy, except with a few minor changes.
 * When blasting off from the Starting Planet, the volcano will erupt similarly to the Mt. Molten volcano in Melty Molten Galaxy from the first game, except that this volcano has smoke while Mt. Molten does not. Also, the player is not able to go inside the volcano, and it releases Star Bits when it erupts.
