Cosmic Cove Galaxy

Cosmic Cove Galaxy is a galaxy in World 2 in the game Super Mario Galaxy 2. Penguins, Snoodles and Skeeters inhabit this galaxy. Coach and Penguru can also be found here.

Starting Area
The player will land on a sandy shore whose only inhabitants are the Coach and a Koopa. The player will need to use the Green Shell provided by the Koopa to swim through the next area. Many Snoodles are found inside the undergroud tunnel and a Porcupuffer can be found at the end of the tunnel.

Cosmic Cove
After the player emerges from the tunnel, they appear in this vast area. The whole area is underwater except for some platforms and a tower. The Comet Medal is located inside one of the giant shells underwater. A giant Jellyfish lurks underwater as well as many Skeeters striding on the water. There is a Hungry Luma here that will transform into the Star Bunny Planet if fed 15 coins. Penguru can be found on one of these platforms. During the first mission, there is a switch that can freeze the water, allowing the player to traverse it with ease.

Twin Falls
This area consists of two large waterfalls. After freezing the water, the player can wall jump up the waterfalls and onto the pieces of land on which they flow. A Power Star is located here during the "Twin Falls Hideaway mission".

Cosmic Cavern
This part of the galaxy consists of an underwater sidescroller section with a few Penguins, Brick Blocks and Gringills in it.

Water Maze
This area has a body of water hovering in space, surrounded by several small Black Holes. All the liquid in the area forms a maze, with some platforms floating over the surface. Near the end of the area there are some red-framed tubes with large cubical water bubbles moving through them, and a bunch of Star Bits forming a Star in the background. Mines, Goombas and a Jellyfish can be found here. The player visits this planet to move around in a side-scrolling effect to find a Key to free a Luma in the Starting Area. The floating bodies of water are similar to the ones from World 7-2 in New Super Mario Bros. Wii.

Star Bunny Planet
After feeding the Hungry Luma in the Cosmic Cove area fifteen coins, it'll transform into this planet. It has a Star Bunny that challanges Mario to catch it. It also has a blue ! Switch that freezes the water if Mario pounds it. The player must be careful not to fall in the black hole in the center of the planet and be wary of the Skeeters that lurk here.

Saturn Planet
This planet has a shape similar to that of a sideways Saturn. Mario arrives on bottom side of the planet full of Fizzlits here. There is also a Spin Drill that Mario must use to get to the other side of the planet. Here, there are some Mecha-Koopas which Mario must destroy to unlock the shield protecting a dust patch. When using the drill on it, water will come out and cover the planet. Mario has to swim to platfrom where the Power Star is located.

Twin Falls Hideaway
To complete this mission, Mario has to dive underwater and swim until he reachs a couple of stairs. Then, he must climb them to get to the top of the stone tower where a switch is located. After pounding it, the water in this area will freeze making Mario able to reach the twin falls' tops. To do so, he has to make a Wall Jump on each one of them. The Power Star is in a crystal on the left area. After breaking the crystal, the Star will go to the other side. Mario must jump there and get it. A penguin can be found on Starship Mario after completing this mission.

Exploring the Cosmic Cavern
Upon entering the galaxy for the second time, Mario will find a Luma trapped in a glass cage. And, since he activated the switch in the first mission, the water in this one is also frozen. To get the Key and free the Luma, Mario has to run across the frozen water until he reaches a green Warp Pipe. He must use it to get into an underwater cavern. Here, he has to make his way to its bottom and use another Warp Pipe. This one will lead him to the last area. Here, he has to dive in the globes of water. He should make his way through them until he finds the area with the key.

After getting the key, the plumber must go through the last warp pipe which takes him back to the galaxy's entrance. The Luma will thank Mario and transform into a Launch Star.

When using it, he'll find himself on a mushroom-like planet, he'll find the captain of the Toad Brigade on it. He'll say that there is a Power Star on the other planet. To reach it, Mario must use the Launch Star found on this planet.

In the next planet, Mario has to use the Spin Drill on the right spot to get to the other side. Here, he has to defeat all of the enemies using the drill. When done so, the shield protecting a dust patch will be disabled. When using the drill on it, water will come out and cover all the planet. Mario has to swim in it to reach the Power Star.

Catch that Star Bunny
To complete this mission, Mario first needs to collect fifteen coins in the first area. Then, dive underwater and progress until he gets to the area with the Hungry Luma. After feeding it fifteen coins, it'll transform into a new planet leaving a Launch Star behind it. When Mario gets to this new planet, a Star Bunny will challange him to catch it. To go faster, Mario has to freeze the water on this planet by using the blue ! Switch. If the plumber manages to catch it, he'll be granted with a Power Star.
