Super Mario Galaxy RosalinaSource: iMore

Nintendo is celebrating the 35th anniversary of Super Mario Bros. by bringing three of the best games from the series to Nintendo Switch with Super Mario 3D All-Stars. While the games span three console generations, all of them share the basic mechanic of having Mario jump around collecting things so he can save Princess Peach. In Super Mario Galaxy, you'll be gathering 60 Stars so you can reach the center of the universe and confront Bowser, but there are 120 Stars that completionists will want to pursue.

Those stars are scattered on planets throughout numerous galaxies, so we've put together a guide to where to find each of them. We've divided it up by observatory and galaxy to make it easier to navigate.

Limited release

Super Mario 3D All-Stars

Three remastered classics

Super Mario 64, Sunshine, and Galaxy are being remastered for Nintendo Switch for a limited time. These classics will be available from September 2020 through March 2021, so you better get them soon if you don't want to miss out.

All Stars in Super Mario Galaxy

Terrace Observatory

Super Mario 3d All Stars PiranhaSource: Nintendo

Once you fly to the Comet Observatory, the Terrace will light up and be open for you to visit. All of its Power Stars have been stolen, and you'll need to travel to various galaxies to recover them and gain access to other areas and in turn more galaxies. The Terrace is found inside the green-roofed building to the left of Rosalina.

Good Egg Galaxy

Once you step onto the Terrace, a blue Luma will transform into a Pull Star. You'll see all the galaxies that can be visited from the Terrace and the number of stars required to access them but for now, your only choice is to travel to the Good Egg Galaxy. Here's how to find all the stars there.

Dino Piranha

You'll earn your first star by winning a boss fight against an angry fusion of a dinosaur and a piranha plant. Damaging him requires spinning near the bulb coming out of his tail, which causes it to slam into his head. Circle around him to avoid getting hit yourself. You'll need to hit him three times to win.

A Snack of Cosmic Proportions

Find all the star pieces on the galaxy's seventh planet to create Pull Stars, which you can lock onto to float upwards. Keep doing this until you hit the Power Star, which will take you back home.

King Kaliente's Battle Fleet

Wait for King Kaliente to shoot coconuts at you, then spin to send them flying back at him. The boss will release the Power Star after you've hit him in the head three times. The first coconut will hit him the first time you spin it, but the next two will require some volleying.

Dino Piranha Speed Run

You'll have just four minutes to get to and defeat the Dino Piranha again. Run to the underside of the planet and climb the tower to reach the Launch Star. Talk to the Luma who will create a Sling Star so you can reach it. Get to the next planet and gather up five Star Chips. Three will be within sight when you land and two will be on the other side of the planed in the path of a Chain Chomp. Grab them all, then enter the launch star.

Kill the Piranha Plant closest to your landing spot to spawn a vine to get to the next planet. Run along the path avoiding Chain Chomps and pits. Hit a green bulb into the purple Piranha Plant at the end of the path to spawn a vine you can climb to another planet.

Climb to the top of the structure there and the Spin attack the glass to uncover a Launch Star. That will take you to the Dino Piranha, which you defeat the same way you did to get your first star.

Luigi on the Roof

You'll receive a letter from Luigi letting you know he found a Star but can't get back home. It contains a picture showing him on top of the house at the beginning of the Good Egg Galaxy. Choose the first Star, the Dino Piranha planet.

Walk to the bottom of the planet and you'll find a red Warp Pipe tucked between two trees. It will take you to an underground area where you can grab a ? coin and music notes then travel down another Warp Pipe to reach the house. Talk to Luigi and he'll give you the star.

Purple Coin Omelet

In all the Purple Coin Challenges you have to collect 100 purple coins. For this one you'll find 15 on the planet you land on and then break a crystal to access a Launch Star. Use it to grab 10 coins in the area and then reach another Launch Star for another 10 coins.

You're going to repeat this process launching in and out of space and onto planets until you've collected everything. After gathering your last 10 in space, you'll land on a planet right next to the Power Star.

Honeyhive Galaxy

Super Mario 3d All Stars BeeSource: Nintendo

After defeating King Kaliente, you'll return to the observatory and can set out to your second galaxy. This is also the first one where you'll be using one of the game's special costumes; Mario must don a bee suit. Here's the buzz on where to find all the Honeyhive stars.

Bee Mario Takes Flight

Use your bee suit on Planet Three to latch onto the queen bee's fur and find the five-star shards that are making her itchy. They'll make a Launch Star appear behind her. Take it to the top of a tree in Planet One, the central area of the Honeyhive Galaxy.

There you'll meet the Toad Brigade, a group of five Toads that will help you throughout the game. Talk to their captain and he'll give you a Power Star which will send you back to the Observatory.

Trouble on the Tower

Kill the Mandibugs on the observatory deck of Planet One, then ground pound a red switch to turn on a windmill. You can ride it to the observatory where you'll need to fight a stronger Mandibug. The star will be yours once you ground pound it twice.

Big Bad Bugaboom

Super Mario Galaxy BugaboomSource: iMore

You'll need to face off against the Bugaboom, an enormous Mandibug. You'll need to ground pound it when it charges you, but the boss makes things more complicated by flying around in the second phase of the fight. You can get above it by spinning around a flower, which will whip you into the air. Then ground pound again.

The Bugaboom will speed up and spew bombs onto the ground. Stay safe by clinging onto a cluster of honey, waiting for your moment to hop off and ground pound it again. Defeat the boss and get the Power Star.

Honeyhive Cosmic Mario Race

You'll race Shadow Mario for the Star, following a course marked by giant arrow signs. Don't worry if he gets ahead of you; you'll have moments to catch up.

Take the path and go right when it splits, heading towards the waterfall. Jump towards the tunnel, grab the ledge, and head for the tree stump. Slide down, do some platform jumps, and avoid the honey which will slow you down. If you don't miss any of the jumps, you should be able to get the Star before Shadow Mario.

Luigi in the Honeyhive Kingdom

Return to the Honeyhive Galaxy, put on your Bee Suit. Fly to the high ledge to the left of the waterfall where Luigi is stuck in a tree. Jump to him to get the Star.

The Honeyhive's Purple Coins

The objective here is to gather the 100 purple coins. They're a bit more scattered this time around, so here's where you can find them all.

  1. There will be 10 coins where you land.
  2. Look left of where you land. You'll spot a tiny ledge with a single purple coin on it. Grab it!
  3. Follow the path to the right and nab another where boulders are falling off.
  4. Stay on the path until you spot a grey boulder. You'll need to pound it to sprout a vine. Don't climb yet! Keep walking and grab a swing and use it to get a coin above you.
  5. Next, do some ledge climbing and wall jumps to pick up more coins until you get to where the boulders emerge. Some more coins are lining a pond.
  6. Jump to the waterfall and ground pound the gray blocks until another coin appears. Jump up to the ledge with the waterfall to grab two more coins near Warp Pipe.
  7. Collect more coins as you follow the ledges while desperately trying not to fall.
  8. Turn around when you hit the dead end, running back to the Warp Pipe. There are two coins just over the cliff ledge.
  9. Use the Pipe; it will take you to a cliff where you can climb the vine that you spawned from the boulder. When you land, head left and collect three more coins on the edge of a tree. Head back to the boulder and use the trampoline to propel yourself into another coin.
  10. Grab more coins around the vine and on the path around the giant tree. Take the brown ramp to collect five more coins on your way to a small stump with a switch you can ground pound to deploy a bridge.
  11. Cross it and flip another switch then climb the wall collectin four more coins.
  12. Jump to a coin on the left cliff edge, then fall onto the brick blocks below you. They each have a coin. Then fall to the tunnel and go down it to collect three more coins.
  13. Hop into a stump and collect five more as you slide.
  14. Use the Warp Pipe at the bottom. Go back to where the red switch was and the jump into the pool nearby to nab another coin.
  15. There are two more coins hidden behind a spire near the pond.
  16. Follow the ledge and you'll find three more coins, then cross the bridge that the red switch created and jump to the top of the wall.
  17. Gather the three coins around the pond and jump onto the cliff edge to get another one. Then jump to the opposite ledge where you'll find three more coins at the edge.
  18. Jump back onto the first edge and you'll see five more coins on a ledge below you.
  19. From the bottom left corner of the ledge, you can backflip to a higher ledge behind the waterfall to get your last five coins.

The Star will appear right where you started the challenge, so just fall down into the pool where the waterfall empties and jump down.

Loopdeloop Galaxy

This planet will teach you to ray surf, coasting along while trying to avoid flying off the edge of the track and dying. Try to grab the 1-Up near the start of the track for some protection. Your penguin coach will award you with a Power Star if you can finish the race in under 90 seconds.

Flipswitch Galaxy

You'll need to turn all blue flipswitches on the planet yellow to get the star. Start by walking over all the switches you have access to then jump on a platform to take you to more. Watch out for the electrical pulses that periodically come from a machine.

Bowser Jr.'s Robot Reactor

Super Mario Galaxy MegalegSource: iMore

Use a Launch Star to get you to the second planet where you'll fight Megaleg. Climb up his legs and avoid Bullet Bills to defeat it. You'll need to get a Bill to lock on to you so it will destroy the grating around the Star. That will cause another gate and a bunch more Bills to spawn. This gate rotates, so you'll need to time things right to get a Bill to blow through it so you can get past and grab your prize.

Fountain Observatory

Super Mario Galaxy KamellaSource: iMore

After you acquire the Grand Star from the Terrace, the Fountain Observatory will open up and give you access to five new galaxies to explore. Head down the path to the left of the Terrace and use a blue pad on the floor to get to the ledge with the Fountain. At this point in the game, you'll also start seeing comets that you'll need to access some of the stars. Keep a lookout for them.

Space Junk Galaxy

As the name implies, the Space Junk Galaxy is full of discarded stuff like debris, rocket ships, and platforms. You'll spend much of your time using Pull Stars to get around.

Pull Star Path

Use Pull Stars to navigate between a series of spheres. You'll collect components to craft a Launch Star and use it to get to a rocket, then ride the Pull Stars to the next area. Break crystals to rescue the Toad Brigade and hitch a ride on their ship to the final area of the level.

The path will build as Mario approaches and crumble once he leaves. Move slowly to find five silver stars needed to create the Power Star.

Kamella's Airship Attack

Fight the Magikoopa Kamella by grabbing the shells that pop out of her staff and throwing them back at her. She'll conjure some backup after she's hit twice, so kill the regular Magikoopas and then smack her once more to get the star.

Tarantox's Tangled Web

Super Mario Galaxy TarantoxSource: iMore

The second boss fight of the galaxy is against Tarantox. Use the Sling Pods to propel yourself into the monster's butt. This will stun him, causing him to expose his vulnerable belly which you need to hit three times before he gets back up.

When you get to the end, jump to another platform and attract the eye of a Bullet Bill. You'll need it to smash through a glass display case holding the Star.

Breaking Into Battlerock

This Star is also shielded, so you're going to need to grab one and run to the other side of the planet and use it to blow up the casing around a cannon. Take control of the artillery and wait for your shot as shields move around the Star.

Topmaniac and the Topman Tribe

Super Mario Galaxy TopmaniacSource: iMore

Luigi and the Disc

Go to Battlerock Barrage and get the five Blue Star Chips to form the Pull Stars needed to reach the Launch Star. Spin ontop of the screw on the next planet and then dodge the electrical fields and cannonballs until you can jump onto the platform at the end of the track.

Collect five Star Chips to produce four Pull Stars and a Launch Star near where you started the level. The Launch Star will take you to the Bump Appear Planet where you can find a Star Bunny. Use a switch to make it easier to catch him and reveal the Power Star.

Cataquack to the Skies

Defeat two Undergrunts on the Cataquack planet, each of which is circling a patch of grass. Guide a Cataquack from one patch to the other and use it to launch yourself up to a Bee Mushroom. Lead the Cataquack to the base of a tower so it will launch you, then start flying to the top.

You'll arrive at a circular platform with a Wiggler on it. Make your way through some flower platforms infested with Flipbugs until you get the Power Star.

When It Rains, It Pours

Super Mario Galaxy Undergrunt GunnerSource: iMore

The Undergrunt Gunner shoots bubbles that will cause Mario to lose your Bee Suit and kick him out of the area. If you're flying, you can damage the Gunner's cap. If you lose the buff, you'll need to use a switch to raise some platforms that will let you get to its weak point. The Power Star appears once you've ground pounded the boss three times.

Cosmic Mario Forest Race

Race Cosmic Mario across Reverse Kingdom Planet to claim the Power Star. Take the leftmost path at the first fork where you'll find a block you can jump across to a wooden walkway. Take it to more blocks that you'll jump up, then go right to a whin wooden walkway hanging above the ground. It will take you to an octagonal wooden platform where the Power Star is.

Purple Coins in the Woods

You have three minutes and 30 seconds to collect 100 coins and bees will show up throughout the mission to let you know how many you should have at that point in the mission. The layout is the same as When It Rains, It Pours, but there's no Bee Mushroom.

Jump up some blocks to collect six coins, then gather more from the wooden walkway and nearby hollow stump. Climb up some blocks and cross thin wooden walkways collecting more coins. Ground pound the trampoline at the end to get more coins. Use another trampoline to get to a swing that will take you to a wooden staircase.

Climb the stairs to get more coins until you get to a circular path with more coins. Head right until you get to some high platforms. Jump to them until you get to a plateau with more coins. Get to a platform with a Sling Star and a single coin in an alcove.

Use the Sling Star to get to a platform with a railing. Grab the coins then trampoline to another Sling Star that will take you to a platform with a railing topped by coins and a stone block. Break it to spawn a vine that you'll climb to get to a circular platform with spikes and more coins. If you collect them all, the Power Star will appear here.

The Bell on the Big Tree

Navigate to the area of the Reverse Kingdom Planet where small boulders appear and you'll find a pen with a Cataquack inside. Use it to launch yourself into a Sling Star. Activate it and you'll be sent to an area with a big tree and a bubble blower. Blow the bubble upwards to find a bell, which you'll use to generate music notes. Collect them all and the Power Star will appear.

Sea Slide Galaxy

You need 36 stars to access this beach-themed galaxy, where you'll be doing a lot of racing against aquatic creatures.

Going After Guppy

The orca Guppy will challenge you to swim through eight rings that he leaves in his wake as he travels through the Sea Slide Galaxy's water ring navigating various hazards and obstacles. Use Red Shells to make this easier. If you swim through all eight, Guppy will give you the Power Star.

Faster Than a Speeding Penguin

Talk to the red penguin to join a race. Grab a Red Shell or spin to stay competitive, going through a longer version of the course you did with Guppy. Swim through Boost Rings to speed up. If you cross the finish line in first place, you'll get the Power Star.

The Silver Stars of Sea Slide

Use Bee Mushrooms to collect five Silver Stars, which will cause the Power Star to spawn in the starting area. The Silver Stars can be found:

  • On top of the stone arch where you met Guppy.
  • Using Pull Stars from the Starshroom.
  • On top of a tree near the stone tower.
  • On top of the large tree near the starting area.
  • On the island in the center of Sea Slide Galaxy.

Underwater Cosmic Mario Race

Cosmic Mario will challenge you to a race. Grab a Red Shell to keep up and use the Boost Rings. The Power Star is in the back of the tower.

Purple Coins by the Seaside

Use Bee Mushrooms to gather 100 coins, some of which are high up on clouds. None of the coins are in the water or on the center island.

Toy Time Galaxy

You need 40 stars to access this playroom-themed galaxy, which contains a planet that pays tribute to Super Mario Bros.

Heavy Metal Mecha-Bowser

Ascend Mecha-Bowser's conveyor belt feet, avoiding getting crushed by the wheels. Wall jump until you get to the green platforms that you'll use to get up Mecha-Bowser's legs. Spin to unscrew two blue screws and create a Sling Star above the platform.

Unscrew four yellow screws while avoiding Fire Bars to reveal a Warp Pipe. Take the pipe to a platform with mini Mecha-Bowsers. Climb up Mecha-Bowser's arm and unscrew a yellow screw. Take the Launch Star that appears to a long mesh platform. Use a Spring Mushroom to bounce to Mecha-Bowser's head and Ground Pound the pillar to destroy it and get your Power Star.

Mario Meets Mario

Collect five Star Chips to form a Launch Star that will take you to the 8-Bit Mario Planet featuring Shrinking Tiles, rotating platforms, and pools of lava. Navigate these obstacles to collect Five Silver Stars which will cause the Power Star to appear at the planet's starting platform.

Bouncing Down Cake Lane

Fight the Undergrunt Gunner boss by Ground Pounding it three times. You can reach it through a Spring Mushroom located at the back of the planet. Avoid its balls of electricity.

Fast Foes of Toy Time

Activate all the Flipswitch Panels around the planet like you did in the Flipswitch Chain, though the Tox Boxes and platforms will be moving significantly faster. The Power Star will appear on an orange cube on the bottom of the planet when all the switches have turned green. This will also cause the spiked platforms to stop moving.

Luigi's Purple Coins

You have three minutes to collect 100 of the 150 coins scattered on the bottom of the 8-Bit Mario Planet, which looks like Luigi. You'll need to navigate poison and platforms. The Power Star will appear on the starting platform and you have to make it back there and grab it before you run out of time.

The Flipswitch Chain

Play through the Mario Meets Mario mission until you get to the screw planet. Instead of gathering Star Chips, you'll need to grab 50 Star Bits to feed the Hungry Luma. It will transform into a new chain of planets covered in flipswitch panels, tox boxes, and moving, spiked platforms. The Power Star will appear on an orange cube under the planets once you've turned all 15 switches green.

Bonefin Galaxy

Super Mario Galaxy KingfinSource: iMore

Sand Spiral Galaxy

Use a Sling Star to launch over a wall into an area filled with floating mines and rotating platforms. Use the Rainbow Star powerups along the path to destroy the mines and reach the Power Star on top of the moon.

Bowser Jr.'s Lava Reactor

Super Mario Galaxy King KalienteSource: iMore

You'll fight King Kaliente again and just like last time, he'll shoot fireballs and coconuts. Spin coconuts to send them back at him and then volley until he fails to knock it back at you and gets hit.

Once you've hit the boss once, he'll launch some Lava Bubbles. Hit him a second time and meteors will start raining. Hit him a third time to defeat him and get your Grand Star.

Gateway Galaxy

This is the very first galaxy that you'll explore and its mission serves as your tutorial.

Grand Star Rescue

On the first Metal Planet, you'll rescue a caged Luma by defeating a big Goomba to get its key. You need to talk to the Luma first. The Luma then turns into a Sling Star which you can use to get to a second Metal Planet where you need to fight another Big Goomba to free another Luma.

Follow the Luma to a Warp Pipe which will take you to an area filled with yellow Flipswitch Panels and moving electrical platforms. Step on every switch to shut down a machine in the middle of the area and grab your first Grand Star.

The Underground Ghost Ship

Super Mario Galaxy KamellaSource: iMore

Fight Kamella who will attack you with red magic that turns into a fireball when it lands on the ship and green magic that transforms into a Green Shell. Throw the Green Shells back to damage her and cause her to start moving around her ship.

Bubble Blastoff

Boo in a Box

Make your way to the bottom of the underwater cave and grab the Green Shell. Toss it at one of the mines around the broken ship mast to cause it to explode and reveal a Launch Star that will send you inside a floating box.

Flip the arrow to change gravity until you're standing on the right wall and you'll find a hole blocked by a crystal. Shatter it to let in light that lures the Boo over to destroy it. It will drop the Power Star.

Dreadnought Galaxy

You need 48 stars to access this galaxy, which reuses some elements of the Battlerock Galaxy but centers around a massive spaceship.

Infiltrating the Dreadnought

Take a Warp Pipe to a Tower Plant where you can use the Topmen as springs to climb a rotating tower. Wall jump up two walls to get to a Launch Star that will take you to the next planet.

Dreadnought's Colossal Cannons

Avoid cannonballs being fired from the Dreadnought and step onto a platform to get it to start moving. Navigate the platforms, some of which change the flow of gravity when you're on them, and avoid the enemies and obstacles. The Power Star is above a Jump Beamer at the end.

Topman Tribe Speed Run

Melty Molten Galaxy

You need 52 stars to unlock this galaxy made of lave and rock, which is the last major dome galaxy of the game.

The Sinking Lava Spire

Through the Meteor Storm

Once you're on the U Tower Planet lure Bullet Bill to the starting area to destroy a cage containing a Launch Star. You'll need to use a Star Ball to roll over lava platforms and through meteors.

Fiery Dino Piranha

Super Mario Galaxy Fiery Dino PiranhaSource: iMore

The Fiery Dino Piranha uses the same tactics as the Dino Piranha but will burn you if you touch it and leaves a trail of fire behind when it moves around. Wait for its tail to be extinguished then spin into it to knock it into the eggshell and shatter it. The boss will then start chasing you.

When the tail is extinguished again, spin into it to hit it into the boss' head. Once it's been damage three times it will start shooting fireballs. Each hit also shortens the amount of time when the tail isn't on fire. Hit it one more time and you'll get the Power Star.

Lava Spire Daredevil Run

Complete the entire Sinking Lava Spire with just one health. If you take and damage, you'll have to start the mission from the beginning.

You'll be sent to another planet where Bowser will shoot fireballs and ground pound. He'll curl up and roll at you and you'll need to stun him by hitting him with one of the planet's rubbery bulbs. Spin him twice to get to the last phase of the fight.
