Cosmic Cove Galaxy

"Awww... I'm sick of swimming all the time. Is it ice-skating season yet?"

- Penguin

Cosmic Cove Galaxy is a galaxy in World 2 in Super Mario Galaxy 2. It is primarily a water-themed level, where players can freeze the water in the first mission to skate on the ice and up water falls, or swim through caverns to find key objects. Penguins such as Coach and Penguru appear as inhabitants of this galaxy, where they can assist players by giving them helpful hints. Common enemies here include Skeeters and Koopa Troopas, as well as underwater enemies such as Snoodles. This is the only galaxy in World 2 with two main missions. One of its levels, Catch that Star Bunny, makes Cosmic Cove Galaxy the only galaxy in the game that has a mission that involves catching a Star Bunny.

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

After players emerge from the tunnel, they appear in this vast area. The entire area is underwater except for some platforms and a tower. The Comet Medal is located inside one of the giant shells underwater. A Jellyfish lurks underwater as well as many Skeeters striding on the water and Cheep-Cheeps. 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, players 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. Many Thorny Flowers grow from the walls of this cavern. A Warp Pipe that leads to the Water Maze is found at the end.

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 group of Star Bits forming a Star in the background. Mines, Goombas, a Paragoomba and a Preying Mantas can be found here. The player visits this planet to move around in a side-scroller to find a Key to free a Luma in the Starting Area.

This planet is a spherical rock with a large stone wall splitting both halves. Players arrive on bottom side of the planet full of Fizzlits here. There is also a Spin Drill that players must use to get to the other side of the planet. Here, there are some Mechakoopas which players must destroy to unlock the shield protecting a dust patch. After players use a drill on it, water comes out and floods the planet. Players have to swim to platform where the Power Star is located.

After players feed the Hungry Luma in the Cosmic Cove area fifteen coins, it transforms into this planet. It has a Star Bunny that challenges 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 holes that lead to the Black Hole in the center of the planet and be wary of the Skeeters that lurk here.
