Battle Belt Galaxy

Battle Belt Galaxy is a galaxy appearing in the game Super Mario Galaxy 2. It is located in World 6. The galaxy is unique in that in order for Mario to advance, he will need to defeat every enemy on a planet. The enemies start easily with foes such as Goombas, Urchins, Burn Bits, and Crabbers. However, the planets will get progressively harder with enemies like Pumpkinhead Goombas, Boos, Brr Bits, and Monty Moles. On the final planet Mario will need to defeat four Silver Chomps using the green stretchy plants. Gobblegut is fought as a hidden boss when the player feeds a Hungry Luma on the Ice Planet 20 coins.

Mini Planet Daredevil Run
A Prankster Comet star, this is the above mission, but done with one health point. Check points are available, something new to Galaxy 2's Daredevil missions.

Snacktime for Gobblegut
This is a hidden mission activated by feeding a Hungry Luma 20 coins on the Brr Bit planet. Gobblegut returns, this time fiery. He is fought the same way as before, but this time he can bite chunks out of the planet, creating temporary lava pits, and after taking some damage can spit fireballs as well.
