Mario & Luigi: Superstar Saga

Mario & Luigi: Superstar Saga (known as Mario & Luigi RPG in Japan), is a Role Playing Game developed by AlphaDream and released for the Game Boy Advance in 2003. It is the first game in the Mario & Luigi series. The game takes place in the Beanbean Kingdom, where the Mario Bros. and the game's protagonist Mario and Luigi are chasing down the villains Cackletta and Fawful to retrieve Princess Peach's voice.

A remake of the Mario Bros. arcade game was also included with Mario & Luigi: Superstar Saga. This is identical to the version found in the Super Mario Advance series of games.

Story
The Goodwill Ambassador from the Beanbean Kingdom and her assistant arrive at the Mushroom Kingdom to bring a gift from Queen Bean for Princess Peach. However, it turns out to be an act of deceit. The ambassador and her assistant are actually evil villains named Cackletta and Fawful. Fawful uses his Headgear to suck up the smoke, which engulfs Princess Peach's voice. They escape with the stolen voice into the dark sky.

Meanwhile, Mario and Luigi are at their house. Luigi is hanging up clothes when Toad walks by asking where Mario is. Luigi is too busy to help, so Toad rushes inside his house and hears Mario singing in the bathroom. After the Toad accidentally runs into a wall, Mario he hears him groaning about the Princess, who is in trouble again. Mario quickly runs outside to put his clothes on, and the Bros. rush to the castle. Bowser, who arrived at the castle before the Mario Bros., becomes enraged and fights Mario. After being defeated, a Toad then tells them that Peach's voice is replaced with an explosive vocabulary. Bowser, scared the princess might wreck his castle if kidnapped, agrees to help Mario retrieve Peach's voice.

Mario and Bowser get ready to leave in the Koopa Cruiser along with Bowser's underlings. As they are about to leave, Luigi comes to say his final goodbye. Bowser mistakenly thinks Luigi wants to join he and his underlings, so he takes him along. The Koopa Cruiser flies off to the Beanbean Kingdom, where Cackletta and Fawful are.

That night, while Bowser and the Mario Bros. are on deck, Luigi spots Cackletta and Fawful coming their way. Cackletta sends Fawful in to fight them, but loses. Fawful then uses his headgear to inviolate the cruiser. Everyone on the Koopa Cruiser plummet down to Stardust Fields.

Mario and Luigi crash land in the Beanbean Borderlands. They soon meet the Border Bros., whom will let them pass only if they play The Border Jump game. The bros. succeed, and they are given a Map of the Beanbean Kingdom to help them on their adventure. They soon find Bowser stuck in a cannon, and a creature named Tolstar begins to mock him. Tolstar tells the Bros. to get 100 Beanbean Coins, and they eventually retrieve enough to satisfy Tolstar's bribe. Instead of helping out, however, Tolstar decides to attack the brothers. He is soon defeated. Straight after, one of the Starshade Bros. arrives and lights the fuse of the cannon Bowser is stuck in, causing him to shoot across the kingdom.

The brothers soon make it to Hoohoo Village, where some Beanish soldiers mistake them for foes. After being permitted entry to the town, they soon leave to find Fawful tormenting a soldier. He mocks the brothers by placing a rock statue in front of them, blocking their path to Beanbean Castle. They decide to visit the Hammerhead Bros. back at the village to make Hammers for them. However, the Hammerhead Bros. cannot make hammers because the material they have is too brittle. They need a Hoohoo Stone, so the brothers climb up the Hoohoo Mountain to retrieve one from the summit.

Midway, they confront a statue named Hoohooros whom challenges the Bros. to a battle. They overcome Hoohooros and they continue up the mountain. When the Bros. finally reach the summit, they find a Hoohoo Stone, but it falls off the mountain. This awakens Blablanadon, who is mad at what they did. After the Bros. explain the incident, Blablanadon apologizes and explains that he has been sitting on a strange egg for some time. Suddenly, the egg hatches, revealing Dragohoho. The creature knocks Blablanadon away and fights the brothers. They defeat the monster, which transforms into Prince Peasley, the prince of the kingdom, who thanks the Bros. for freeing him. Blablanadon flies the plumbers back to Hoohoo Village, where they meet the Hammerhead Bros. again. With the Hoohoo Stone that fell into the Hammerhead Brothers' cabin the Hammerhead Bros. are able to make them the hammers they require.

Using their hammers, they demolish Fawful's statue and travel down Hoohoo Mountain towards Beanbean Castle Town. Along the way, they find a cave. Inside is an old man and his beanish dog, who asks them to ride the Mysterious Mine Carts. Afterwards, the Mario Bros. reach Beanbean Castle Town, but they find the town in ruins because of an attack from Cackletta and Fawful. The brothers quickly go to Beanbean Castle, where they meet up with Lady Lima, the kingdom's ambassador. They tell her what's going on, but she does not believe their story. She sends them down to the castle sewer to fix a leaking pipe problem. Once it has been fixed, the brothers meet up with the real Lady Lima and some servants. The Bros. learn that they had fallen for one of Cackletta's schemes. The witch had been pretending to be Lady Lima the whole time, and fixing the castle's plumbing disabled the security system which protects the Beanstar. The brothers catch up with her, but it is too late. Cackletta takes the Beanstar away and sends Queen Bean to attack them. The queen has become a muscular monster as a result of eating a Belly Blech Worm. Mario and Luigi are then sent to get the antidote for the queen: the Chuckola Reserve.

Later, the Mario Bros. make it to Chateau de Chucklehuck to find the reserve. They end up in a fight with Popple, the shadow thief, and his partner, Rookie, who are both defeated. The brothers soon meet Cork and Cask, the owners of the brewery. Mario and Luigi later retrieve three Chuckola Fruit to give to Chuckleroot. When they reach Mother Chuckola, they find the creator of Chuckola Cola, Bubbles, who is busy telling jokes to the Chuckola Reserve. The soda then transforms into the Chuckolator. After a battle, it reverts into normal soda. Bubbles is not happy about it, creating a tremor that sends the brothers and the soda underground. Mario lands in the soda. Luigi, doing a barrel run on Mario, heads to the Beanbean Castle.

Back at the castle, Luigi jumps on Mario to squirt out the Chuckola Reserve into Queen Bean. She spits out the Belly Blech Worm, returning to normal. Peasley then arrives to report to the queen. Cackletta is hiding out in the Woohoo Hooniversity, so the Mario Brothers are sent there to investigate. At the Hooniversity, they must unlock the Sun Door to reach Cackletta and Fawful. They are about to awaken the Beanstar using Peach-bots that are installed with Peach's voice. When Cackletta activates them, they make a strange noise that drives the Beanstar crazy. It causes a tremor, sending the robots and itself falling to the floor below. The Mario Bros. then appear, and Luigi bashes Fawful into the ground with his hammer, leaving Cackletta to fight them alone.

After the battle, Fawful gets back up, and uses his headgear to suck up her essence, dissolving her body. He is about to battle the brothers, but Peasley arrives and throws him out of the building. The prince departs, leaving the brothers to go down to the basement to retrieve the Beanstar. There, they find Popple and Rookie with the Beanstar, and they fight for it. A Peach-bot later falls down and makes the noise again, irritating the Beanstar. Mario, Luigi, Popple, and Rookie grab a hold of it as it flies out of the university. They soon let go and fall, as does the Beanstar itself when it breaks into four pieces. Rookie suddenly remembers that he is really Bowser.

Mario and Luigi land at Oho Oasis. They learn the Firebrand and Thunderhand moves in the Fire and Thunder temples. Meanwhile, Fawful finds the injured Bowser lying on the ground and implants Cackletta's soul inside him. The Mario Bros. soon meet Peasley again, saying that Princess Peach is arriving at the Beanbean International Airport. They arrive and find that Piranha Plants are infesting the runway. They take care of this problem, and the Toad Express lands safely.

Back at the castle, the Mario Brothers find out that Peach's voice had never been stolen. It was really Birdo disguised as the princess at the time who lost her voice. Peach knew about this all along, as Peasley came and told her about Cackletta's plan beforehand. Later, Peach decides to visit Little Fungitown, with the Mario Bros. escorting her.

They arrive at the only known route to Little Fungitown, Teehee Valley. Before reaching the town, they are confronted by the rock creature, Trunkle, whom they overcome. At Little Fungitown, the Bros. decide to go to the arcade, where Mario plays one of the games and wins an Invincishroom. He eats it, but ends up in the hospital, where he has contracted Bean Fever. The only cure for this disease is Crabbie Grass from Guffawha Ruins. Luigi accepts to travel to the area to find the grass, but loses his nerve when he finds out about a bone-crushing monster living there. To try and calm himself, he goes to Psycho Kamek, who hypnotizes him into thinking that he is Mario.

Luigi goes to Guffawa Ruins. Soon after confronting the "monster," who is actually just a stone head wishing people would stop making rumors about him, Luigi finds some Crabbie Grass. He goes back to the Little Fungitown hospital, but is struck by lightning. He then spots Peach in the Koopa Clown Car. The fiend in the vehicle is Cackletta, who has possessed Bowser's body to become Bowletta. She makes off with Peach, and Luigi rushes into the hospital to revive Mario. Luigi tells Mario about what had just happened, and both of them quickly return to Beanbean Castle.

Back at the castle, Lady Lima comes with a message from Bowletta, who is requesting that they retrieve the four pieces of the broken Beanstar to her in exchange for the princess. The Mario Bros. and Prince Peasley agree to do this task.

Mario and Luigi go out to get the first Beanstar piece, which is in the S.S. Chuckola back at Teehee Valley. After the ship is sent into the Oho Ocean, the Mario Brothers follow the floating Beanstar to Gwarhar Lagoon. Here, they receive new abilities for their hand powers from the Jellyfish Sisters. They later discover that the Beanstar piece is being used as an ornament for Hermie III. The brothers soon receive the piece after a battle with Hermie.

The next piece is from the fashion stylist Harhall, who gives Mario and Luigi the piece after they color fabric with Designbombs. Another piece comes from Boddle after they get Neon Eggs for his Yoshi Theater sign. The last piece is back at Chucklehuck Woods, where they have to play a game in the Winkle Colosseum and surpass the Winkles. They soon find Popple, whom they defeat to retrieve the last piece of the Beanstar.

They return to the castle with the star, where Lima has brought another message from Bowletta. She now wants them to bring the Beanstar to her at Joke's End. Prince Peasley gives them a Fake Beanstar to try and fool the villains. They then surf to Joke's End.

There, they meet a fairy-like girl named Jojora. Eventually, the brothers reach Jojora's room at the top floor, where she is having a tea party. She requests that the brothers invite one of her friends over, who is a female snow woman that attacks Mario and Luigi. They defeat her, and Jojora flees from the scene. Soon after, Mario and Luigi find Fawful, who is waiting for them to hand over the Beanstar. Luigi approaches him, and gives him the fake one. But Fawful is not fooled. He blasts Luigi and takes the real Beanstar. Mario comes up with a plan involving the extra dress Toadsworth gave to them before they went to Joke's End. Bowletta, who has the real Peach, soon spots Mario with another Peach. The other Peach says that the one the villains have is fake. Angered, Bowletta tosses what they believe to be the "fake" Peach overboard and takes the "real" one back to the repaired Koopa Crusier.

Back at the Cruiser, Bowletta and Fawful are celebrating their success, until Bowletta finds out that the princess is really Luigi in disguise. Fawful chases him, followed by Bowletta, until he manages to escape the cruiser with the Beanstar. Upset, Bowletta decides that she and Fawful will go to the Mushroom Kingdom for something.

Back at Teehee Valley, Luigi crash-lands into a sand pit and sinks in. Mario manages to find him underground, but the two end up fighting Popple again. Popple is defeated, along with his new partner, Birdo. Afterwards, they head back to the Castle Town.

Unfortunately, the brothers find that the town is under fire again. It appears that Bowletta is using Bowser's Castle to attack the town. At the castle, Lima suggests that they should try and find something to help them fly to reach the castle. The brothers head back to Hoohoo Village to ask for Blablanadon's help. He accepts, and takes them up to Bowser's Castle.

At the castle, Mario and Luigi meet the Koopalings, along with Fawful, who possesses some new gadgets. After fighting the foes, the Bros. make their way to Bowletta, who reveals her plan to take over the Mushroom Kingdom after she is done gaining control of the Beanbean Kingdom. The brothers fight her and supposedly win, until a countdown Bob-omb comes and takes out almost all the entire HP the brothers have. Bowletta had been only faking her defeat, and she eats them alive. In her body, the Mario Bros. fight Cackletta again, although this time in her spirit form. Mario and Luigi soon manage to defeat Cackletta once and for all. She spits them out of Bowser's body, silently groans, and vanishes, never to be seen again. Bowser also returns to normal, unconscious on the floor. Peasley then comes to address the brothers, saying that he has planted a detonator in the castle, and it will explode shortly. The brothers escape the castle via Blablanadon in time, but Bowser crashes into Oho Ocean, only to be rescued by Prince Peasley.

Later on, Peasley drops by with a huge present for the brothers. The heroes return to the Mushroom Kingdom via Peach's airplane. They fly over the ocean as the sun sets and reach the Mushroom Kingdom at night. Peasley's present turns out to be Bowser, who is dropped off at his other castle. The plane lands at Peach's castle, and fireworks erupt. It is then shown that a movie of the adventure is being shown in the Yoshi Theater, where the screen zooms out to show the Yoshis sitting in the theater and applauding.

Locations
Though much of the action of this game takes place in the Beanbean Kingdom, Mario and Luigi can still venture towards several areas in the Mushroom Kingdom. All Beanbean Kingdom locations' names except for Yoshi Theater and Little Fungitown have different names pertaining to laughter. The following is a list of various areas the brothers journey to throughout the course of the game:


 * Mushroom Kingdom
 * Koopa Cruiser
 * Stardust Fields
 * Hoohoo Village
 * Hoohoo Mountain
 * Beanbean Castle Town
 * Beanbean Castle
 * Chucklehuck Woods
 * Woohoo Hooniversity

 * Oho Ocean Seabed
 * Gwarhar Lagoon
 * Yoshi Theater
 * Joke's End
 * Bowser's Castle

The game also has several secret caves which can only be visited by either Mario or Luigi acting separately from one another. These areas start as 2-dimensional, side-scrolling levels in the traditional platforming style. A rare item can be obtained from a Monty Mole if the caves are completed.

Battle system
To start a battle, Mario or Luigi must touch an enemy. They can also perform a First Strike by jumping on the enemy in the over-world. This will damage the enemy before the battle starts. Since the game is an RPG, the player and enemies will take turns attacking each other. The player can use good timed attacks to deal more damage. If Mario and Luigi take damage from enemies in the overworld they will take damage when a battle starts.

Stats
Each brother has their own Heart Points, Bros. Points, POW, DEF, SPEED, and STACHE points. When they finish a battle, they each gain Experience Points. With enough Experience Points, they can level-up and increase each respective statistic.


 * HP (abbreviation of Heart Points) is the amount of life Mario and Luigi has. When an enemy hits either of them, they lose HP. When their HP reaches zero, they pass out, but can be revived with a 1-Up Mushroom or 1-Up Super.
 * BP (abbreviation of Bros. Points) indicates how many times Mario and Luigi can use a Bros. Attack. Each attack uses a certain amount of BP, draining the total. BP can be restored by using a Syrup, Golden Mushroom or a 1-Up Super.
 * POW (abbreviation of Power) is how strong either Mario or Luigi is. The higher their POW stats are, the more damage they will perform.
 * DEF (abbreviation of Defense) is how much damage either Mario or Luigi can block from an enemy hit. The higher their DEF stats are, the less damage they will take.
 * SPEED is how fast Mario or Luigi are. The more SPEED they have, the more they can attack an enemy in a given turn.
 * STACHE is the most unique of Mario and Luigi's stats. The higher their STACHE stats are, the greater there is a chance of a Lucky, which doubles POW, and it also lowers the prices of items bought at shops and increases the worth of items sold (caps at 50%).

Moves
During battle, Mario and Luigi will have four options when it is their turn: Use a Solo Move, use a Bros. Attack, use an item, or run.

Solo Moves
During a Solo Move, Mario or Luigi will use one of their basic attacks solo. Both bros. have solo move techniques that they can use in any battle in the game. Note that all of these techniques listed below must be learned by progressing through the game except for Mario and Luigi's Jump.

Solo Techniques

 * Mario's Solo Techniques
 * Jump - Mario uses his famous jump to squash enemies.
 * Hammer - Mario can use his hammer to hit enemies.
 * Hand - Mario can use his Firebrand ability to burn enemies.


 * Luigi's Solo Techniques
 * Jump - Luigi can use his jumping ability to crush enemies.
 * Hammer - Luigi can use his hammer to hit enemies.
 * Hand - Luigi can use his Thunderhand ability to electrocute enemies.

Bros. Attacks
Bros. Attacks are attacks that Mario and Luigi can use in battle by working together to deliver more damage. They all use a different combination of buttons to hit.

There are three different modes present for reach Bros. Attack. Mode 1 consists of slow motion and visual button commands appearing when the command needs to be pressed, acting as a guideline for players. Mode 2 removes the slow motion but retains the visual button commands. Mode 3 removes both the slow motion and visual button commands, and in turn, less Bros. Points are used for the Bros. Attack and depending on the move it will deal more damage.
 * Mario's Bros. Attacks
 * Splash Bros.
 * Chopper Bros.
 * Fire Bros.
 * Swing Bros. (secret)


 * Luigi's Bros. Attacks
 * Bounce Bros.
 * Knockback Bros.
 * Thunder Bros.
 * Cyclone Bros. (secret)

Items
When choosing the item icon, Mario or Luigi can use an item to recover HP or BP. Other items, such as Refreshing Herbs, can heal status effects, and red or green peppers will raise POW and gain weight or raise DEF and lose weight respectively. When one of the bros. passes out, the other bros. can use a 1-Up Mushroom or 1-Up Super the revive them. However, once an item is used, the bro's. turn is over.

Run
Mario and Luigi can both run from battle when they choose the run icon. When getting away, the player must hit either the A or B button to make a bro. run. However, if they don't do this quickly, one of the bros. will drop a large amount of coins. When both bros. have left the screen, the player will end up back in the overworld and continue their adventure. This feature works better if one of the brothers has passed out. Instead of running, the remaining brother picks him up and carries him away, halving the number of coins lost.

Avoiding attacks
Superstar Saga allows the player to completely avoid enemy attacks. Mario and Luigi can either use their Hammer or Jump moves to avoid attacks. With their Jump move, Mario or Luigi can simply jump over the attacking enemy. When using the Hammer to avoid attacks, the player must hold Mario or Luigi's respective button (Mario is A, Luigi is B) and release just as the enemy or their weapon hits.

Mario and Luigi can also use these moves to counterattack. When they jump over an enemy, they may land on them, causing damage. Mario or Luigi can also hit enemies with their Hammer during their turn.

Out-of-Battle Techniques
Mario and Luigi can also use some techniques out of battle. Once again, all of the following techniques must be learned by progressing in the game, except for jumping.

Enemies
The following is an alphabetical list of all 55 non-boss enemies found in Mario & Luigi: Superstar Saga. The name of each enemy, their stats, and locations found in the game are provided. Please go to the respective page of each enemy for further information.

Please note that some of these enemies are variations of a single enemy or were fought in a grouped-battle. For convenience, these variations are listed as separate enemies.

Bosses
There are 28 bosses in the game. They are listed below in chronological order. The Koopalings are fought in the same order they are fought in Super Mario World.

Items
These items are used in battle or in the overworld.

Sidequests
As typical to the Mario RPG games, there are various sidequests that Mario and Luigi can complete outside the main story. These quests result in various things, from simply helping an NPC character to receiving items as awards that can be used in the main quest.


 * Near the start of the game, if a Toad is spoken to while Mario's holding Mushroom found on a hedge nearby, he will ask for it back. If Mario does so, the Toad reward them with a Super Mushroom.
 * Close by, there is a blue Toad that has lost an item important to him. If Mario can find it and return it to the blue Toad, he is awarded with a 1-Up Mushroom.
 * Before going to the Koopa Cruiser, a lost minion asks Mario and Luigi for directions to the ship. If given correct directions, he rewards Mario and Luigi with a 1-Up Mushroom.
 * Hundreds of Beans are hidden throughout the over-world that the Mario and Luigi can find them and spend at the Starbeans Cafe in the castle town. There are four different kinds of beans in existence: Woo beans ([[File:BeansWoo SS.png]]), Hoo beans ([[File:BeansHoo SS.png]]), Chuckle beans ([[File:BeansChuckle SS.png]]), and Hee beans([[File:BeansHee SS.png]]). Depending on which kinds of beans Mario and Luigi find, different blends will be able to be produced. When Mario and Luigi produce a blend, Professor E. Gadd will give the Mario Bros. a prize. When the Mario Bros. drink the blend, they will also gain a stat boost. The possible blends, beans required, stat boosts, and prizes are listed below.


 * Some caves near the Beanbean Castle Town offer a quest to complete the obstacle course that references Super Mario Bros.. There are three caverns containing these courses. Two of them are north of Beanbean castle, while the third is found to the west of Beanbean castle. If Luigi or Mini Mario finishes, there is a Monty Mole who gives him a Rare Item such as a High-End Badge or the Iron Pants.
 * A citizen on the east side of Beanbean castle town is searching for five Beanlets and when spoken to, he will ask Mario and Luigi to find them for him. If they find them and give them back to his proprietor, he gives them a Golden Mushroom.
 * In Beanbean Castle Town (West side), there is an old Beanish scholar that asks Mario and Luigi to find ten jewels called "Beanstones". To find these, Luigi must hit Mario with the hammer to shrink him and walk around town. If tiny Mario is standing over a beanstone, a "!" appears over his head. Luigi must now dig in this spot to retrieve it. There are ten beanstones; five on the east side of town and five on the west side. If all ten are found, the old citizen gives them a rare item: the Bros. Rock.
 * There are large Koopa Troopas in some caves of the game where Mario can use his Firebrand power to knock them over, allowing Mario and Luigi to pass. There is a Monty Mole there that gives them a special item, such as a Golden Mushroom.
 * There is a cave where Mario and Luigi's hammers can be improved by the Hammerhead Bros. In this cave, there are Thwomps who host a guessing-game. Mario and Luigi have to pay a hefty fine of 200 coins (500 for the second Thwomp game) and use their upgraded hammers to smash one out of three boulders. If they are lucky, they can find the scrolls wielding hidden Bro Moves.
 * There is an island called "Surfing Game Island" where Mario and Luigi can get free beans for accomplishing a game, in which they are given a set time to break as many balloons on their board as possible. The faster they complete the course, the more (or different) beans they will receive. To find it, enter the green pipe leading to Gwarhar Lagoon, break the black brick, and turn Luigi into a surfing board. Enter the ocean above and move 3 areas right, and two up.
 * After the Bros. receive Ultra Hammers, they can go to an area of Gwarhar Lagoon blocked by rocks that were previously indestructible. They will find Spangle there. Giving Hermie Spangle will make him happy, and he will give them the Soulful Bros. badge.
 * After the Bros. receive the Bean Star Piece from Harhal, Harhal opens her store and the Bros. can work for her to create all of the outfits. Mario and Luigi are able to create a possible maximum of 28 designs: 7 different shirt colors and 4 patterns for each one. When a new outfit is created, Harhal will give Mario and Luigi a Woo bean. When Mario and Luigi complete all 28 different designs, they will earn Harhal's Pants.

Quotes
Some notable quotes in the game include:


 * "We'll take my Koopa Cruiser and reach the Beanbean Kingdom in no time! Mario! We leave immediately!!" – Bowser
 * "Who would have thought you'd catch up to the Great Cackletta in even a hundred million years?" – Cackletta
 * "I am the great Cackletta's most best pupil, who is named Fawful! I am here, laughing at you! If you are giving us the chase, just to get your silly princess's voice, then you are idiots of foolishness!

Beta elements


Many characters from other Nintendo franchises were to appear in the Starbeans Café, such as Fox McCloud, Link and Olimar These characters were replaced by E. Gadd in the final game. The dialog of the characters can still be seen in the game's code. A mysterious, cloaked Beanish character was left unused. Its purpose in the game is unknown.

Glitches
Most of the glitches found in the game are graphical related, such as misplaced Bob-omb sprites and incorrect action icons being shown when facing Bowletta. A notable graphical glitch is seen in Little Fungitown, where Mario and Luigi are able to stand on thin air. Some other glitches cause the game to play incorrect music or sound effects. For example, in the northeast of the Teehee Valley entrance, instead of Luigi making his normal sound effect when he empties himself of water, the sound of an Oho Jee speaking will play instead.
