Slimy Spring Galaxy

Slimy Spring Galaxy is a galaxy appearing in the game Super Mario Galaxy 2. It is located in World 6. It is a galaxy that mostly takes place under water. It makes extensive use of the Green Shell to move around underwater. Common enemies here include Snoodles, Urchins, and Boos.

Snoodle Spring Planet
One of the only two planets in the galaxy, the explored part seems to be inside a cave. Mario starts the level in a watery section with a lot of grass. There are two Swoopers flying around in this area. After going down a slope, Mario will enter an underwater cavern where several Snoodels are found. The Comet Medal is found inside a wall here. Green Shells are found here, and at the end of the planet are a Launch Star and several Urchins.

Boo Spring Planet
After falling down a deep hole, Mario will enter another underwater section. This one is much longer, and Mario must use the Green Shells, Boosters and Bubbles to get to the end before he runs out of air. At the end is a place with a lot of vegetation, an orange skyhere and a chest. When opened, the captain of the Toad Brigade comes out and rewards Mario with a Power Star.
