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.

This is the main planet of the area. It is shaped like a fish. Its interior is 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.
