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 jellyfish appear in the water.

The underground lake.

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 on on the roof. Several jellyfish and Gringills live in the bottom lake. 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.

  • Bigmouth Galaxy may be named after an actual fish that is sometimes called the bigmouth bass.
  • 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.
  • Bigmouth Galaxy shares a few similarities with Slimy Spring Galaxy from Super Mario Galaxy 2. Captain Toad is stuck inside a treasure chest at the end of the galaxy, underwater sections are meant to be navigated with a shell, and a large horde of Boos appears in the water.
  • This galaxy is the only galaxy to have five yellow Star Chips that form a Sling Star.
