Super Mario Galaxy/Melty Molten Galaxy

Melty Molten Galaxy is accessible from the Garden observation dome.

Star 1: The Sinking Lava Spire
There is a hidden Star here. For the time being, ignore the Hungry Luma you meet.

Star 3: Fiery Dino Piranha
In this level you will reach a Luma Shop to buy either a 1-Up Mushroom or a Life Mushroom for 30 Star Bits. The Life Mushroom might be useful if you need help during the upcoming boss fight.

Boss Fight - Fiery Dino Piranha. This boss fight is the same as Star 1 in the Good Egg Galaxy, except you can only attack when his tail is not fiery, and you need to watch out for fireballs.

If you need to replenish your health, there is a coin trapped in crystal, and you can fire Star Bits at two flowers to receive coins.

Star 4 (Daredevil Comet): Lava Spire Daredevil Run
Same as Star 1, one with just one life point.

Star 5 (Purple Comet): Red-Hot Purple Coins
100 Purple Coins, no time limit.

Star 6 (Hidden): Burning Tide
Enter Star 1. Feed the Hungry Luma 80 Star Bits.
