Obscure Stars

Some stars are found out-of-order. We'll detail those stars here.

Comet Missions

Many of the larger galaxies in the game have comet missions attached to them. As you play through the game, you will eventually notice a purple Luma appear near Rosalina. This Luma can help you control the comets as they wander around the multiple galaxies; pay it 20 star bits to move the comets to a different galaxy if you don't want to play the missions that they offer.

There are four types of comet missions that you will encounter. Each galaxy only has one comet mission of a specific type. In other words, you'll always encounter a Speedy Comet above the Good Egg Galaxy; it'll never be a Daredevil or Fast Foe comet, or anything else.

Speedy Comet: You have to complete the entire mission while operating under a time limit. The mission itself is otherwise unchanged, so if you've already played it you will at least have the advantage of knowing what to do. Ignore out-of-the-way coins and powerups, and focus on getting your job done here.

Dural?

Cosmic Comet: Cosmic Comets will reveal a cosmic Mario twin that you have to race in order to get to the Power Star first. The easiest way to complete these is to simply hang back, watch your twin maneuver the course, die and restart, and then do everything your twin did, but do it more rapidly.

Daredevil Comet: Annoyingly, these comets force you to replay part of a mission (usually a boss fight) with only one sliver of life remaining. There are no coins to heal with, so if you take any damage, you die.

Fast Foe Comet: Your enemies will move twice as fast in fast foe missions, but apart from that these missions are much the same as they were previously.

Hungry Luma Stars

Hungry Luma stars are obtained from the galaxies that are created by the Hungry Lumas. As you play the game, you'll notice that Hungry Lumas will appear outside the observatories that you've unlocked, and demand that you feed them star bits. If you do so, they'll transform into new galaxies that you can explore. These galaxies are often fairly challenging, but will each contain a Power Star for you to obtain at the end.

Sweet Sweet Galaxy

The Sweet Sweet Galaxy is obtained by feeding the Hungry Luma that appears outside the Terrace Observatory. If you travel to it, you'll have to make your way across some exceedingly tricky jumping puzzles to reach the Power Star that's hidden away there. There's not much to explain; just get jumping!

Sling Pod Galaxy

Head to the Fountain and pay the Hungry Luma outside of it her star bits to unlock the Sling Pod Galaxy. As the name implies, this area is filled with sling pods, so you'll have to pull them to and fro to move Mario along. Towards the end of the galaxy, the throws get wickedly difficult, so come in with plenty of 1-Ups.

Drip Drop Galaxy

This is the galaxy that's unlocked by the Hungry Luma near the Kitchen. If you head here and dive into the water, you'll be able to tag three of the giant eels underneath the waves with red shells. Killing them all will net you the Power Star.

Bigmouth Galaxy

Outside the bedroom is this Hungry Luma. Head to his galaxy and grab the green shell on the beach. Take that into the water and barrel through the brick wall ahead of you. On the ground in this large, water-filled room are five golden star shards; collect them all, and a launch star will appear in the middle of the octopi. Ride it to the shining shell, then ride that back to the beach (the light from the shell will kill the Boos in the water). Use the shell to break open the chest to gain the Power Star.

Sand Spiral Galaxy

The Hungry Luma behind the Engine Room starts this one. Start off with the Boo Suit here; it's a bit easier to get to the end of the hallway with it, as opposed to the Bee Suit, or so we've found. When you reach the rotating disc area, grab the Rainbow Suit and run to the left, heading for the narrower portions of the track. Eventually you'll be able to jump to the moon in the middle of the Track and claim the Power Star.

Some of these challenges are easier than others.

Boo's Boneyard Galaxy

Find the Hungry Luma outside the Gate platform for this galaxy. This is another race, but this time you'll be in Boo form the entire time. Just head straight down whenever possible, using the invisibility power to get through the crystals, and you should win the Power Star.

Snow Cap Galaxy

Lastly, the Hungry Luma outside the Garden observatory will have this galaxy on tap, if you have the 1,600 star bits it wants.

When you land on the first little orb here, you need to head to the bottom side and make a blind jump to reach a green shell, which you can use to open the nearby chest. That'll launch you over to a pill-shaped galaxy where three bunnies challenge you to catch them before the timer runs down. This is difficult to do, and will take a couple of tries.

To start with, you need to find the five blue plates and step on all of them. There's one near where you begin, one buried underneath the small patch of snow (use your cursor to brush it away), two buried in the larger patch of snow near all the snowmen, and one on the lower end of the planetoid. Hit them all, and the bottom of the planet opens up, revealing a Fire Suit.

This is one of the harder challenges.

Use the Fire Suit to reveal a bunny in one of the snowmen, but let it roam free for now. Keep using the Fire Suit on the snowmen until you have the free bunny and a green shell. Use the shell on the treasure chest to reveal the second bunny. Now head around the cylinder with your cursor and sweep the snow off of the holes in the ground. The third bunny will pop up from one of them.

With the bunnies on the surface, you need to herd them back into the hole at the top of the cylinder so that they're all in one place. If you can do that, you can grab them without having to chase them far. If you're lucky, one or two of the free bunnies will head into one of the holes while you're sweeping for the third. Catch all the bunnies, and you get your Power Star.
