Super Mario and the Underworld Trials is a 3D platforming game for the Nintendo Switch, developed by Crash Co. and published by Nintendo. It is the seventeenth title in the Super Mario series, is the eighth original 3D Super Mario title, and the ninth 3D Mario title overall. The game has Mario, Luigi, and several others getting trapped in a mysterious underground world called the Underworld, and need to escape by collecting Mystic Stones through the Underworld Trials.

It has been stated that while Super Mario Odyssey focused on story, Super Mario and the Underworld Trials will focus on character interraction and character development.

Story

Opening Cutscene

The beginning of the game opens at Bowser's Castle. Bowser has kidnapped Peach, alongside Toad and Toadette, and Mario, Luigi, and Yoshi are ready for a final battle with him. Bowser calls upon Bowser Jr., who appears in his Jr. Clown Car and shoots a cannonball at Luigi, knocking him away. Yoshi then throws an egg at Jr., and pounces on him afterwards. This only leaves Mario and Bowser, who begin battling with Peach cheering on. Outside of the castle meanwhile, Wario and Waluigi are staring through the throne room's window, and plan on breaking into the castle and stealing Bowser's treasury. The two sneak into the castle as fighting is going on and attempt to open the vault door. Waluigi tries opening the lock combination until Wario uses his signature Dash Attack to ram into the door, unhinging it and knocking Waluigi into the vault too. The two then stuff the Coins, Gold Flowers, Diamonds, and various artifacts from Mario's adventures Bowser stole into a large bag and sneak back out. The bag however springs a leak, and Coins start dropping from it. This goes unnoticed until Bowser accidentally slips on one, causing him to fall over. He looks at Wario and Waluigi, now making a getaway, and roars angrily.

Just as he does however, the ground begins shaking, with all of them shocked at this ocurrance. The ground then begins to split open right under Bowser, causing him to fall through. Mario, being heroic, follows Bowser into the pit, with Luigi and Peach following. Yoshi is about to jump in as well, but noticed Wario and Waluigi sneaking off. Yoshi grabs Wario with his tongue, dragging him into the pit with him, leaving Toad, Toadette, Bowser Jr., and Waluigi on the surface as the others are falling through the hole in the ground.

In the Underworld

After awhile, Mario wakes up, taking notice that he is underground in a land full of sparkling crystals and rocks. Mario explores for a bit until he comes across a small town. Seemingly vacant, he explores further and notices a large building in the center, with Luigi, Peach, Yoshi, Wario, and Bowser in multicolored crystals, sleeping. Mario is horrified at first, until he is met with a strange voice behind him. Mario turns around and sees a beautiful woman, seemingly made of crystals. She correctly predicts that Mario has a lot of questions and that she has answers, but tells him to come to her house for more information.

Mario and the woman then arrive at her house, which is rather large. She tells the plumber to have a seat on a large table in the kitchen, providing him with some special Crystal Juice. He turns down the offer, and asks her who she is and where he is. The lady introduces herself as Ruby, and tells Mario that he and his friends fell through a large crack in the ground and ended up in the Underworld. Mario is about to reply, until a small girl appears and asks Ruby who the new guest is. Ruby introduces this girl as Pearl, her daughter. Pearl then pilotely greets Mario, who greets back. Ruby then tells Pearl to wait in her room until she is done talking with Mario, who oblidges. Mario asks how he and his friends are able to get out of the Underworld and back to the Mushroom Kingdom, to which Ruby replies that there is a way of escape in the form of the Underworld Trials. She explains that it is unknown who built them or how they were built, but says that they were created to test the strength of anyone brave enough to take them, and the reward for clearing them would be escape from the Underworld.

Mario asks how these Underworld Trials can be cleared, to which Ruby replies that each of the trials contain special objects called Mystic Stones, and if enough are collected an exit can open, allowing escape. Mario then asks how he can free his friends, and Ruby answers by saying that some trials hold special Mystic Stones that can free anyone from the trapped crystals, and also explains that Mario was lucky he did not land in one of these special crystals. Mario thanks Ruby for the information, and says that he will take these Underworld Trials to escape. As he is about to exit, Ruby stops Mario and calls down Pearl. When she comes back down, Ruby asks if she would be willing to let Mario stay in her room for a few days, with Pearl happily replying yes. Pearl grabs Mario and rushes up to her room, showing Mario her bed, her bookshelf, and her toy chest. She also goes into her closet and pulls out a sleeping bag that Mario can use. Mario thanks her, and goes to sleep, concluding he will try to escape the following day.

The Adventure Begins

When Mario exits Pearl's room, he finds Toad, Toadette, Bowser Jr., and Waluigi talking with Ruby, the former two of which are overjoyed to see Mario awake. Mario asks what they are doing here, with Bowser Jr. responding by pulling up a monitor from his Jr. Clown Car, unveiling Professor E. Gadd. The professor states that he created an invention to safely allow the four to enter the Underworld, and is currently researching how to exit it. The professor also brings up how he is studying how the large hole appeared in Bowser's Castle, to which Ruby is surprised at. She explains that she wasn't aware that this could happen, and decides to keep talking with E. Gadd to find out more about the situation, using her trident to take the monitor off the Jr. Clown Car, much to Bowser Jr.'s anger.

Throughout the game, Mario goes through the Underworld Trials and collects the Mystic Stones, inching him closer to escaping the Underworld. As he collects them, he begins freeing his friends, releasing Luigi, Peach, Yoshi, Wario, and Bowser in that order. All is going well until Mario enters an area known as Starshine Resort. All is well and good until at one point the ground begins shaking, and he is booted out of the level and back into the Underworld. Confused, Mario enters the area again and is horrified to find that the area is in total ruin, being completely destroyed and shrouded in dark storm clouds. He finds the Mystic Stone and exits the area. He reports this to Ruby, saying that the area was destroyed, leaving nothing but the Mystic Stone. Pearl becomes scared, though Ruby assures her that she will look into this with E. Gadd. In the meantime, she tells Mario and co. to keep collecting the Mystic Stones.

Obsidia Appears

Once Mario and his allies have collected enough Mystic Stones, Ruby contratulates them, saying that they finally have enough Mystic Stones to go back to the Mushroom Kingdom. She does say, however, that they may never be able to visit the Underworld again, making Pearl quite sad. They all bid their farewells as Ruby takes the Mystic Stones with her magic. They all begin to light up and a portal is created, which showcases the Mushroom Kingdom. Just as Mario and the others are about to go through the portal and return to the Mushroom Kingdom, Ruby is suddenly struck by a magic force, causing the portal to glitch out. Just then, a shadowy figure appears from the background, chuckling menacingly. Ruby recognizes her as Obsidia, her younger sister who she encased in a crystal long ago. Obsidia says that she escaped when the heroes fell on the crystal she was trapped in - specifically Wario and Bowser - allowing her to break free. She uses her magic to have the Mystic Stones empower her, covering her in a purple aura and making her stronger. Obsidia then takes the portal to the Mushroom Kingdom so she could rule over it, but not before taking Pearl with her, saying that she is just taking "what is rightfully hers". As Pearl screams for her mother's help, Obsidia enters the portal, bent on ruling it over, and the portal disappears.

Mario and Peach help Ruby up, as the queen decides to explain everything. She and Obsidia used to rule the Underworld together. However, she saw darkness in her heart and saw through her plans of universal domination, and knew that she needed to be encapsuled for everyone's sake. The two battled, but Ruby eventually overpowered her and encapsuled her in a crystal. But now that she escaped, both the Mushroom Kingdom and Underworld are in danger. As such, Ruby decides to do the one thing she hoped it would never come to; she uses her powers to open a temorary portal to the Mushroom Kingdom. She begs Mario to stop Obsidia and save the Mushroom Kingdom and her daugher. Bowser is the first to run in, with the others, including the Rescue Squad, following.

Final Battle

When everyone arrives to the Mushroom Kingdom, it appears that Obsidia has already taken control. The skys is purple and cloudy and the once lively plains are now dead and covered in black crystals. Bowser notices that light is coming from his castle, and once the heroes arrive there, it is shown that Obsidia has made the castle her new lair. She thanks Mario and co. for collecting all the Mystic Stones so she could finally escape the Underworld. She also revealed that she tried collecting them herself, but decided to wait instead, seeing as the heroes were already passing the Underworld Trials. Pearl, who is in a crystal, begs for help, and the heroes decide to take down Obsidia while the Rescue Squad breaks Pearl free. Obsidia vows to take control of the universe and destroy all those who dare get in her way, including Mario. She empowers herself with the Mystic Stones and the final battle begins.

Obsidia is bested. Confused about how she lost, she begins to lose all her power from the Mystic Stones. She then faints as the heroes rejoice in their victory. Meanwhile, Bowser Jr., Toad, Toadette, and Waluigi manage to rescue Pearl, who runs up and hugs Mario, thanking everyone for rescuing her. However, their victory is cut short when Obsidia regains her footing. She says that if she's going down she will take everyone with her. Using the last of her power, she uses a large-scale suicidal attack by exploding, creating a void that will vaporize everything it pulls in. Mario and co. escape and manage to narrowly escape the Mushroom Kingdom through the portal Ruby created.

Back in the Underworld, everyone is celebrating their victory against Obsidia, and Ruby thanks the heroes dearly for rescuing her daughter. However, Pearl wonders what Obsidia meant when she said "what's rightfully hers" when she kidnapped her. Ruby kneels down to her and tells her something that she admits she should have told her long ago; Pearl is in fact the daughter of Obsidia. Once Ruby encapsuled her in a crystal, she found Pearl and an infant, knowing that she was Obsidia's offspring. She then decided to take her and raise her as her own, in the hopes that she would not become like her true mother. Ruby adds that Pearl must hate her for keeping this a secret for so long, but Pearl, now in tears, runs up and hugs Ruby, saying that she could never hated her and wanted her to be her real mother. The two share an embrace as the heroes look on dearly.

Ending

Some time later, Ruby gathers up the Mystic Stones and opens up the portal to the Mushroom Kingdom again which, thanks to Obsidia's defeat, is now restored to it's normal state. Professor E. Gadd runs up to Mario and congratulates everyone for finally managing to escape. Ruby says that Mario may still never be able to see them again, but E. Gadd explains that he just finished a teleporter, allowing travel between the Mushroom Kingdom and Underworld. Everyone rejoices, and E. Gadd takes out a camera to snap a group picture of the heroes, Rescue Squad, Ruby, and Pearl as he snaps the picture.

Gameplay

The game overall plays like other 3D Mario sandbox games like Super Mario 64Super Mario Sunshine, and Super Mario Odyssey, but mostly the former two. Mario and his friends all have their basic moveset from other 3D Mario titles, such as the Ground Pound, Triple Jump, Backflip, Dive, Wall Jump, and the Roll. This game notably marks the return of Punching and Kicking, last seen in Super Mario 64, allowing Mario an alternative way to defeat enemies.

To propgress the game, Mario must collect Mystic Stones by completing a variety of missions in the Underworld Trials, with such tasks ranging from climbing a large structure, besting an NPC in a race, and defeating a boss. There are 202 Mystic Stones total, though only 100 are needed to complete the game. The main courses of the game contain eight numbered missions, a hidden mission, a Chaos mission, and a 100-Coin mission, adding to 11 total missions per course. Meanwhile, there are also Mini-courses, which only have one numbered mission and one Chaos mission. Throughout these levels Chaos Crystals can also be collected, which are similar to Comet Medals from Super Mario Galaxy 2. Collecting one of these in a course will eventually unlock a Chaos mission, which is similar to the Prankster comets in Super Mario Galaxy and its sequel. Blue Coins found throughout the game can also be collected, and traded into the Underworld Bank for extra Mystic Stones.

Notably, the game makes use of power-ups similar to Super Mario 3D Land and Super Mario 3D World. When collecting a power-up, the character's punching ability is replaced with the power-up's ability. Such examples are the Fire Flower, which allows the user to throw fireballs, a Frog Suit that allows users to swim underwater better, and a Metal Mushroom that allows the user to become metal, making them heavier, stronger, imprevious to fire and lava, and being able to walk through water.

Pearl's Room

Pearl's Room serves as the main residence of Mario, and where Mario can switch out with another character. Pearl is usually found in this room, but can also be seen walking in other parts of the house and in the backyard, as well as in the bathroom (to which she says "Could you go away for now? I'm doing my business."). When talking to Pearl (bar the latter situation), she will talk about how she is happy Mario and the others are staying in her room. She may also ask the player to read her a bedtime story during nighttime, which is similar to Rosalina's Storybook in Super Mario Galaxy. In addition, she can also be seen interacting with the characters that are not being used; such exaples include having a tea party with Peach, watching TV with Wario while he's sleeping, and riding on Yoshi's back as he carries her through the town.

Aside from this, the room is fairly customizable. Throughout the game Mario can collect special items, which can be used at the Underworld Gift Shop to buy items in a similar manner to the Crazy Cap shops in Super Mario Odyssey. When these items aare bought, they can be placed in Pearl's Room. These items include couches, rocking chairs, rugs, lamps, wallpapers, and even different Nintendo consoles like the Nintendo 3DS and Nintendo Switch. Once these items are placed, Pearl can also be seen interacting with them, such as eating chips on the couch or playing The Legend of Zelda: Breath of the Wild on a Nintendo Switch.

Characters

Playable

Character Description Attributes
Mario - SuperMarioRun
Mario
The red-capped hero of the Mushroom Kingdom was fighting Bowser to save Peach before falling into the Underworld. Having woken up, he meets up with Ruby, who tells him that in order to escape he needs Mystic Stones found in the Underworld Trials. And so begins his new adventures to save his friends and return to the Mushroom Kingdom. Mario plays as the most balanced character, allowing new players to get used to the game. He has no special abilities or advantages, and his running speed and jumping height are all balanced.
Luigi Artwork - Super Mario 3D World
Luigi
Luigi, Mario's taller and slimmer brother, became trapped in the Underworld while helping Mario defeat Bowser. He becomes encased in a large, green crystal. Once enough Mystic Stones are collected, Luigi is freed and can travel alongside Mario through the Underworld Trials... whether he wants to or not. Luigi is significantly harder to control than Mario, as he takes quite awhile to slow down after running. To compensate, Luigi has the highest jump height of any of the characters.
Princess Peach Artwork - Super Mario 3D World
Peach
Peach is the princess of the Mushroom Kingdom, who was kidnapped by Bowser. Just as she was being freed, she, Mario, and the others fell into the Underworld. She, alongside Mario's other friends, is trapped in a large crystal, with her's being pink. Once the princess is freed, Peach is able to help out Mario and co. Her royal state is misleading; she is more than capable of taking out baddies herself. Peach moves rather slowly compared to the other characters. However, she is able to use her signature floating ability that allows her to float in midair. This allows her to cross gaps that would otherwise be impossible to clear. Also, instead of punching, she slaps enemies.
Yoshi - Mario Party 10
Yoshi
Yoshi is one of Mario's closest allies, who was helping him battle Bowser to rescue Peach. However, Yoshi and the others fell into the Underworld. Afterwards, Yoshi became stuck in a large blue crystal, and would need to be freed by collecting enough Mystic Stones. Once he breaks out, Yoshi is willing to help Mario and co. escape the Underworld and return to the Mushroom Kingdom. Yoshi has the highest speed of any character, allowing him to move rather quickly. He is also unique in that, instead of punching and kicking, Yoshi can use his tongue to swallow enemies and turn them into Yoshi Eggs. He is then able to throw the eggs at other enemies, defeating them. He is also equipped with his signature Flutter Jump.
WarioMPDS
Wario
Wario is Mario's arch-rival and the master of greed. While Mario and co. were battling Bowser, he and Waluigi snuck into Bowser's Castle to raid his treasury, stealing his riches. However, Wario was dragged into the Underworld, and later became trapped inside a yellow crystal. Once Mario has enough Mystic Stones to free him, Wario agrees to help him return to the Mushroom Kingdom... as long as he gets Bowser's hoard of treasure. Wario moves rather slowly, but he has the highest punching ability of any character, being able to break blocks other characters cannot break. His ground pounds are also significantly stronger than other characters'.
Bowser - Mario Party 10
Bowser
Bowser is the king of Koopas, Mario's arch-rial, and Peach's kidnapper. He was battling Mario to keep him from taking back Peach before being sucked into the Underworld with everyone else. Here, he gets encased in a red crystal, and Mario must free him by collecting enough Mystic Stones. Once the Koopa king is freed, he and Mario agree to set aside their differences and help each other return to the Mushroom Kingdom. Bowser is the largest, heaviest, and slowest character, who has low jumps to boot. However, instead of punching he is equipped with his signature fire breath that can defeat enemies in front of him over a large radius.

Levels and Missions

All of the levels are located in the Underworld Trials, and are divided into four main sections, as well as a final area and a bonus section. Unlike other 3D Mario titles such as Super Mario 64 and Super Mario Galaxy, several missions in a given level are already unlocked, and can be played in any order. Clearing all of these missions will unlock another mission. Each area consists of up to eight of these tasks, as well as two additional tasks - one of which is unlocked after collecting the Chaos Crystal in the level and the other being a secret task - which may be played again at will once they are completed. Once the player has collected enough Mystic Stones in total, a new set of levels is available in the Underworld Trials.

Not listed here are the Mystic Stones collected from tading in Blue Coins to the Underground Bank. In a similar manner to Super Mario Sunshine, 10 Blue Coins are found in each level, and they can be turned into the bank for extra Mystic Stones.

The Rescue Squad: Birthday Blitz

Birthday Blitz

The Rescue Squad: Birthday Blitz is a large-scale expansion pack of Super Mario and the Underworld Trials, which notably has the Rescue Squad as the main playable characters.
