Bigmouth Galaxy

"This is my hideaway. It's the perfect spot for fishing...and being left alone!"

- Penguru

The Bigmouth Galaxy is a galaxy unlocked by feeding a Hungry Luma in Super Mario Galaxy. The galaxy consists of one large planet shaped like a fish with a wide open mouth that has stalagmites resembling teeth. The majority of the galaxy's sole mission takes place in a large body of water, which is accessed via the mouth. Gringills, Boos, and a Jam-o'-War appear in the water. The Bigmouth Galaxy may be named after an actual fish that is sometimes called the.

This galaxy is the only galaxy to have five yellow Star Chips that turn into a Sling Star.

Planets/Areas
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
This is the main planet of the area. It is shaped like a fish, with its interior full of water. In the belly of the planet are two lakes, one on the floor and one on the roof. Several Jammyfish and Gringills live in the bottom lake, while a Jam-o'-War floats above. When the player enters the fish's mouth, there will be two Boos near the entrance. If the player returns from the lake with the Gold Shell to where the Boos were, there will be lots more of them.

Water Planets
These planets consist of spheres of water and are seen positioned around the Starting Planet. Their dimension considerably increases with distance: the nearest planets are relatively small, while the furthest planets are huge. They are inaccessible without hacking. These planets do not have gravity.

Missions
This galaxy consists of only the following mission.

Trivia

 * It is possible to reach the Gold Shell without collecting the Star Chips. This can be done by swimming to the surface of the large body of water and performing a wall jump into the water on the ceiling, or by using the momentum from a Green Shell to leap.
 * When viewed from the map accessed by talking to Polari, the skybox for Bigmouth Galaxy is not the same as it is when playing the level. It appears to be the same as Space Junk Galaxy's skybox.
