- —Boo, Paper Mario: Color Splash
Boos (originally known as "Boo" Diddlys,[1] a nod to American R&B singer Bo Diddley, and later Boo Buddies[2][3][4][5][6][7] or simply Ghosts[8]) are recurring ghost enemies that first appear in Super Mario Bros. 3. They are a type of white spherical ghost with menacing and normally open mouths. They are known for their large tongues and small stubby arms. However, the most distinctive characteristic of the Boos is their shy personality, as they cover their faces when someone looks directly at them, but then uncover and move after the character when their back is turned; this exact behavior is used by Mumbies in the Kirby series.
Shigeru Miyamoto got the idea for Boo from the wife of his coworker and close friend Takashi Tezuka, as she is shy but one day got very angry with him for coming home late from work.[9][10]
History
Super Mario series
Super Mario Bros. 3 / Super Mario Advance 4: Super Mario Bros. 3
"Boo" Diddlys[11] appear in Super Mario Bros. 3. They are first encountered in World 2-
Fortress. A "Boo" Diddly shields its face if looked at, but chases the player character if not looked at. "Boo" Diddlys can be defeated only from either the effects of a Hammer Suit or a Starman, or from a Koopa shell. "Boo" Diddlys have a variant, Stretches "Boo" Diddlys are depicted with either a dark-blue or dark-red outline in the Family Computer and Nintendo Entertainment System version, depending on the level.
Super Mario World / Super Mario World: Super Mario Advance 2
"Boo" Buddies (called "Boo" Diddlys earlier in development[12] appear in Super Mario World and its reissue. They are encountered in the Ghost House levels. "Boo" Buddies behave identically but move slower than before, a consistency retained throughout the Super Mario series. "Boo" Buddies change their face very briefly if looked at for long enough. "Boo" Buddies appear to have multiple tails. Groups of them make a variety of facial expressions. More varieties are introduced in the game, including Boo Buddy Blocks, Boo Buddy Snakes, Boo Crews, Circling Boo Buddies, Eeries, Disappearing Boo Buddies, and the Big Boo. A "Boo" Buddy is defeated only from the effects of Super Stars or being hit by a Grab Block.
Super Mario Land 2: 6 Golden Coins
Boo Buddies appear in Super Mario Land 2: 6 Golden Coins. Compared to other games, they move in a slower, wave-like pattern toward Mario. Boo Buddies in this game are found in the Pumpkin Zone. A thrown Green Shell can defeat it. A variant named Ghost Goombas also appears in this game.
Super Mario 64 / Super Mario 64 DS
- “Ghosts...don't...DIE! Heh, heh, heh! Can you get out of here...alive?”
- —Message from Big Boo's Haunt
Boos (also called Baby Boos)[13] appear in Super Mario 64 and Super Mario 64 DS. They use their design from Mario Party 4 in the latter version. Boos are encountered in the courtyard of Peach's Castle and in Big Boo's Haunt. Big Boos are recurring mini-bosses in the latter location, as well as a different Big Boo in the Big Boo Battle stage in the remake only. When Boos are looked at, they become partially visible, but are fully opaque otherwise and follow the player character. Boos take away two units of health on contact. The Boos in the courtyard hold a Yellow Coin each, and those in Big Boo's Haunt each have a Blue Coin; the remake changes the former instance to Red Coins until the player collects all eight and then the Power Star. Boos are defeated from either a punch, a kick, a Pound the Ground attack, or Luigi's spin jump in the remake only. Boos cannot be defeated by Yoshi in the remake, and it is spit out if Yoshi attempts to do so.[14] A line of dialogue displays each time a Boo is defeated in the first mission of Big Boo's Haunt.[15] A Boo appears in the hallway of the Mushroom Castle after twelve Stars are collected, or eight in the remake. By selecting the sixth mission of Big Boo's Haunt in the remake directly, a Boo wearing a Luigi's cap appears in the stage.
Super Mario Bros. Deluxe
Super Mario Bros. Deluxe,
arranged by speed
Boos appear in Super Mario Bros. Deluxe. They are competitors in the "You VS. Boo" mode, competing to reach the flagpole before the player can. Boos do not damage the player character on contact. If the Boo is defeated within a time frame, it flies away, being replaced by a faster green Boo, then by a faster red Boo, and lastly a Black Boo[16] with a yellow outline. The Black Boo travels in a way mimicking the player's best time.
Super Mario Sunshine
Boos return in Super Mario Sunshine. They have a different design consisting of drooping eyelids, blue circles around their black pupils, and long, coiled tails, due to being made of goop.[17] They are encountered in Sirena Beach only, inside of Hotel Delfino. Two varieties of Boo appear, Pink Boos and Sleepy Boos, and the boss fought below Hotel Delfino is King Boo. Boos move around in slow, swooping motions. They do not react if looked at. There are Boos that are mostly invisible, besides a distorted visual effect, but spraying them with water makes them become increasingly visible. The invisible Boos take on disguises such as Yellow Coins or Blue Coins, differentiated only from not spinning at a constant pace, or Shadow Mario, differentiated by appearing lighter colored, lacking the magic brush, and the Shadow Mario theme not playing. If a disguised Boo is approached, it laughs and bumps into Mario, unless it has been sprayed prior.
New Super Mario Bros.
Boos appear in New Super Mario Bros. They are encountered in Ghost Houses and World 8-1. They act the same as in Super Mario Bros. 3, though the ways of defeating them include a Shell, a Starman, a Mega Mushroom, or a Blue Shell. The game introduces Balloon Boos, which inhale air to inflate themselves, and Broozers, which are boxers.
Super Mario Galaxy
Boos appear in Super Mario Galaxy. They are encountered in the Ghostly Galaxy, the Bigmouth Galaxy (in underwater areas), the Deep Dark Galaxy, and the Sand Spiral Galaxy only. Boos become transparent when the player character looks at them, but are opaque and go after the player character if they are not looking. A Boo can be defeated mainly from any ray of light, or when touched by Rainbow Mario. Boos can be spun off course from a spin attack. A large Boo in Deep Dark Galaxy has a Power Star in it during the secret mission. Varieties that appear include Atomic Boo and the debuting Bomb Boos, and there is a Boo character who is raced, the Spooky Speedster. One of the power-ups, Boo Mario, has the player character become a Boo, retaining only his face and cap. Boos are attracted to Boo Mario and follow him. If a Boo hits Boo Mario, he does not take damage but does lose the power-up.
Captain Toad also indirectly suggests that Boos eat people, as he worried that Luigi might have been eaten by ghosts.
New Super Mario Bros. Wii
Boos return in New Super Mario Bros. Wii. They are depicted with a blue glow. Boos are encountered in Ghost Houses only. They behave identically as in New Super Mario Bros. Varieties that appear include Big Boos, Broozers, and Circling Boo Buddies.

Once the level is cleared, the Boo only covers its face henceforth. Boos are defeated only from the effects of a Star.
Super Mario Galaxy 2
Boos appear in Super Mario Galaxy 2. They behave identically as in Super Mario Galaxy.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
Boos appear in Super Mario 3D World and its port. Their only differences are cosmetic, being more transparent, having a blueish glow like in New Super Mario Bros. Wii and its sequels unless stared at, in which case they have a reddish glow while emitting steam. Big Boos and Peepas also return.
Super Mario Maker subseries
Boos are course elements in Super Mario Maker, its port, and Super Mario Maker 2. They have newly designed sprites for the Super Mario Bros. style, but are otherwise the same as in other entries of the Super Mario series. Boos can be inserted into Bill Blasters, Blocks, a Koopa Clown Car, tracks, or Warp Pipes. Boos can be shaken to become Boo Buddies or dragged on to platforms to become Stretches. Applying a Super Mushroom to a Boo changes it into a Big Boo, while giving it wings gives it faster movement. Boos in Koopa Clown Cars affect the vehicle to stop and close its eyes when looked at and sneak up on the player while they are not looking.
Super Mario Run
Boos appear in Super Mario Run. They are encountered in Ghost House levels. Boos cover their eyes and float up and down while looked at, including if they are close to the player's vertical position, and turn to look at the player character. Boos otherwise follow in a quick, wavy motion. Boos are defeated by either jumping backward over them using a Backflip Block or a Wall Jump. The pink P Switch of certain levels defeat every Boo on-screen. Boos drop Keys, Coins, or Color coins upon defeat, with the item being slightly visible before their defeat. Boos in the level Dark and Stormy are defeated whenever lightning strikes happen. Boo cannot leveled. Besides Boos, Stretches also return.
There is a Boo Statue in Kingdom Builder, which has an interaction where it briefly covers its eyes.
Super Mario Bros. Wonder
Boos are enemies in Super Mario Bros. Wonder. They are designed similarly to their older artworks but still stick their tongues out.

"The Yoshi Shuffle" includes ghosts in the audience at the start of the episode.
Nintendo Adventure Books
In Koopa Capers, a Boo confronts Luigi if he decides to simply look through a keyhole in a fortress door, instead of barging through it. If Luigi decides to run away from it immediately, he will successfully escape, but if he decides to stand his ground, the Boo will chase him onto some floating blocks after he dodges its attack. Making a beeline for the door after mounting the blocks will allow the Boo to catch Luigi, but doing evasive techniques will allow him to escape it. When he begins his descent into the Magma Pit, Luigi will hear a Boo behind him, which causes him to pick up the pace, and escape it.
Illustrations of a Boo are used in puzzles in Dinosaur Dilemma and Flown the Koopa, though none appear in the actual stories.
Super Mario World: Mario to Yoshi no Bōken Land
In the interactive OVA Super Mario World: Mario to Yoshi no Bōken Land, Boos appear in a Ghost House that Mario, Luigi, and Yoshi are passing through. A Boo starts following Luigi, who is in the back, but every time he turns around, it disappears. Finally, he quickly does a double take, and turns just in time to see it re-materialize. He panics and Boos start swarming the group. Mario grabs a candle and lights it, which repels the Boos, and one drops a key they need to progress.
Yoshi

Boos[23] (misnamed "Big Boo" in the English manual[24]) are enemies in Yoshi's Safari, where they are encountered only in Ghost Mansion.

Yoshi's Island series
Boos are enemies in Super Mario World 2: Yoshi's Island and its port. They are first encountered in World 2. Boos can be defeated only by looking away and making an egg bounce off of a wall after it is thrown, hitting the ghost in the face. Kamek turns one Big Boo into Bigger Boo, which serves as a mini boss and grows in size every time he is hit by an egg. The game introduces two variants: Boo Balloons, which yield items when they pop, and Boo Man Bluffs, blindfolded Boos that rely to noise to locate the player character.
Boos appear in both sequels, Yoshi's Island DS and Yoshi's New Island, behaving identically as in Super Mario World 2: Yoshi's Island and being able to be defeated in the same way as before. In Yoshi's Island DS, there is also a Boo-like midboss in Hector the Reflector. Boos in Yoshi's New Island first appear in Beware the Boo Brigade and retain their laugh from Super Mario 64.
Super Mario RPG: Legend of the Seven Stars
Boos return during the events of Super Mario RPG: Legend of the Seven Stars and its remake. In the original game, the English translation erroneously calls them "The Big Boo", whereas the remake simply calls them Boos. In the Japanese version, they are, in fact, referred to as Teresa as they are in other games. These Boos, like other Boos that appear in previous games, hide behind their arms when stared at. However, some Boos teleport around the room, attempting to scare Mario and his friends. Boos live in Kero Sewers along with many other ghouls, including Hobgoblins and Shadows. Often, these three undead monsters will assist each other in battle. Boos have no physical defense, making them extremely weak enemies (for reference, a Goomba is the weakest enemy encountered and it has three defense points). However, Boos make up for their lack of defense with high evasion, meaning that most attacks against Boos will miss. In battle, Boos command powerful lightning magic, including the attacks Lightning Orb and Bolt. Boos also know the special attack Scream, which cuts a party member's attack and defense in half. When not using magic, Boos approach one of Mario's party members and make a face, damaging that character. In this game, there is also a stronger Boo variation called High Boos, which are the same size as their normal counterparts but have blue tongues, similar to the first appearance of King Boo. The only true appearance of a Big Boo in this game is the one used in Bowser's Terrorize attack.[28] One Boo lives in Monstro Town as part of the Three Musty Fears.
Super Mario-kun
Boos appear in some of the Super Mario-kun comics. A Boo appears on the cover of volume 16, which is based on Super Mario 64. Alongside it, Eyerok, a Bob-omb, and Bowser can be seen. Throughout the comic, they appear, too. Their role in the comic is similar to their role in the game, where they are enemies to Mario and attempt to attack him. Lady Bow, a notable Boo, appears in a couple of the Paper Mario-based issues. These issues are 25 and 27. Lady Bow appears on the cover of the twenty-fifth issue along with many of Mario's other partners, including Goombario, Kooper, Eldstar, and Twink. Besides appearing on the cover, she appears throughout the comic. Her role in the comic mimics her role in the game. Lady Bow reappears on the cover of the twenty-seventh issue and in the comic. Like in issue 25, Lady Bow's role in the comic is similar to her appearance in the game, where she helps Mario. In a Super Mario Galaxy-based issue, Boo Mario appears on the cover along with more of Mario's transformations.
Yoshi's Story
Boos appear in Yoshi's Story. They are encountered in the stage Ghost Castle. Boos do not act differently, although they are slightly bigger. Several other Boos variants are encountered in the level, including Block Boo, Blindfold Boo, and Little Boos. Two variations are encountered earlier on in Jelly Pipe, including Jelly Ghosts and Big & Little Boos.
The normal Boo[29] is mistakenly called a Big Boo[30] in the Nintendo Power guide.

One of the Boos is the host of Boo's Haunted Bash, as well as the fourth host of the Reversal of Fortune. A different Boo is playable in Beach Volley Folley. Boos appear in Long Claw of the Law, possibly as characters to obtain. The host of Boo's Haunted Bash wears a wizard's hat and cape. Other Boos appear in Boo's Haunted Bash: one owns the Item Shop; another owns the Mystery Train, giving rides to the Boneyard if a Red Boo is not in its presence; one has the player character press one of the keys of the Horn of Plenty to get one of three randomly chosen items; and one has to press the correct key at the right time until the end of the side game to get a certain amount of Coins.

At the mention of a theft, the Boos worriedly ask for help to find the golden Boo statue, which they consider a symbol of their friendship. The Boos find that there are four of them instead of the usual three.[31][32] When the Boo with a slightly moveset and rhythm is selected by the player, the false Boo is revealed to be Koopa Kid, who escapes, leaving behind the statue, and the Boos give the player the Predictotron as a reward. The Boos are said to haunt Horror Condo regularly in the epilogue.
Boos appear in the minigames Boo-Bye, alongside Red Boos and Blue Boos; Spooky Spike, serving volleyballs to the player character; and Floor It!, as possible passengers to take to the appropriate floor. The Porta-Gust Gaddget involves sucking Boos into a vacuum.
Mario Party 7
Boo is a playable character in Mario Party 7. He is partnered with Dry Bones. Red Boos have similar roles as in Mario Party 6 since Boo is playable.

Teams compete to find more wanted Boos more than the opposing side.

Paper Mario series
Boos appear in every game in the Paper Mario series, where they are usually found in ghost houses. In the first three Paper Mario games, the Boos appear with a design similar to Bigger Boo from Super Mario World 2: Yoshi's Island. In the latter three games, they use their modern appearance from Mario Party 4 and onward.
Paper Mario
- “I want to hear people shriek and watch them run away yelling! That's what makes Boos happy.”
- —Boo, Paper Mario
Boos appear in Paper Mario as friendly but tricky characters. White Boos live in Boo's Mansion, and tan Boos live at Gusty Gulch. Their leader is Lady Bow, who lives in Boo's Mansion along with Bootler.
At first, Boos were being eaten by Tubba Blubba. Some Boos tried attacking the monster to save their friends, but they failed because of Tubba Blubba's "Invincibility". Seeking help from Mario, they captured Skolar, the Star Spirit Mario was trying to save, in order to have Mario help them.
In the game, when Mario arrives at Boo's Mansion, Bootler tells him to get to the third floor. The Boos have prepared some puzzles for him under the order of Lady Bow to test him. One puzzle is for Boos to form a rotary circle, throw an item several times and ask Mario to guess who is holding the item. The first time he opens a door a big Boo appears on the screen. In the eastern room of the second floor Boos holding a Record play this trick. In the western room of the second floor, a Boo is guarding a chest box with a Weight in it. Mario plays the Record to lure the Boo away and uses the Weight on the droplight of the mansion to open the western door on the first floor. Boos in the basement hide in a big chest box in the basement. When Mario opens the chest box, they play the puzzle with Super Boots. After Mario gets them, he is able to get Boo's Portrait with which he is able to get to the third floor. There, Lady Bow asks Mario to help the Boos to defeat Tubba Blubba as a condition to free Skolar, and joins Mario's party to assist him.
A Boo by the name of Igor also has a shop in the basement, but he will not sell until after Lady Bow joins the party.
In addition, a Boo appears after Mario gets the Super Boots, and tells him how to get the Star Pieces underground. Additionally, some Boos are flying in the sky who can be seen out of the windows. When Mario is about to set off, two white Boos appear to open the gate to Gusty Gulch under the command of Bow.
In Gusty Gulch, upon Tubba Blubba's arrival, the Boos hide except for Stanley, who is too late and gets caught and eaten by Tubba Blubba.
In the basement of Tubba Blubba's Castle, a brown Boo tells Mario not to fight Tubba Blubba until he finds his weak point. According to his word, he sneaked into the castle to look for the weak point. After Mario gets Yakkey, some tan Boos appear in front of Tubba Blubba's Castle and, seeing Mario and Bow get out and Tubba Blubba chasing, help the team by blocking the door.
After Tubba Blubba is defeated, the Boos he has eaten are saved, and Bootler releases Skolar as promised. Boos rejoice, and the background music in Boo's Mansion is replaced with a cheerful one. The Boos at Gusty Gulch write Lady Bow an admiration letter, which the player can read at the Toad Town Post Office. They also begin to talk about a female Boo called Victoria.
After Mario defeats Bowser, two Boos come to Peach's Castle to see the party, one white and one brown. The white one says he comes to see Lady Bow in her finery. He thinks that Bow is prettier than Princess Peach. The brown one says that he is going to have a wedding ceremony after the party. In the end-of-game parade, three white Boos along with Bootler are carrying Tubba Blubba's body.
Paper Mario: The Thousand-Year Door
Boos return in Paper Mario: The Thousand-Year Door and its Nintendo Switch remake as friendly characters as well as enemies for the first time in the series. Some Boos such as Lahla and Peeka in Rogueport can be seen running shops and various casino games. Enemy Boos are found in Creepy Steeple and levels 21-29 of the Pit of 100 Trials. When Mario first enters the steeple there is only one Boo in the room who says that he misses his friends. He will let Mario through only one door (blocking him from using any other doors), where he finds a chest. When he opens it, 200 Boos fly out. The last Boo asks Mario "How many Boos came out of that chest?" If Mario answers correctly the Boo will give him an Ultra Shroom. If Mario is wrong the Boo will give him one coin. Upon returning to the main room, the first Boo is still there. He asks if Mario is going to be mean to him. If Mario answers "No", a bunch of Boos (the same ones from the treasure chest) will start flying around the main room, attempting to swarm Mario. If successful, they will throw Mario out of the Steeple, exactly like the Sentinels in Tubba Blubba's Castle. If Mario Spin Attacks them several times, they merge into an Atomic Boo. Once the Atomic Boo is defeated (releasing a Lucky Start badge), Mario can fight Boos in other parts of the Steeple. Even before defeating the Atomic Boo, Boos can still be found, but only when accompanying Swoopers.
The original Creepy Steeple Boo sends an e-mail to Mario that thanks him for freeing his friends, despite the fact that they attacked him. He signs the letter "The Creepy Steeple Boo". More Boos can be found in the Pit of 100 Trials. In this game, Boos attack by becoming invisible and getting close to Mario or the partner, then becoming visible and making a glare at them, causing 3 damage. However, if Mario or his allies gets lucky in battle, the Boo who tried to attack Mario and his partner will be tired out. The game also introduces a more powerful sub-species, the Dark Boo, which can be found in Poshley Sanctum.
Boos can also appear as members of the audience, where they can throw items onto the stage and randomly turn a character in the battle invisible for one turn.
In the remake, the Boos use their modern voice clips. Additionally, the Creepy Steeple Boo can be later found in the hidden room containing the Cookbook. When spoken to, he will quiz Mario again with three questions about various parts of the game, and will reward Mario with an item if the latter answers all three questions correctly. This can be done multiple times, each with its own trio of questions.
Field Tattle
Outside of battle, Goombella can use Tattle only on a Boo found in the foyer of Creepy Steeple after Mario releases the 200 Boos.
- "That's a Boo. You think it's one of the Boos from that box?"
Super Paper Mario
Boos return as enemies in Super Paper Mario. In this game, they turn invisible if Mario looks at them, but they turn visible and chase him if he is not looking at them, similar to their behavior in Super Mario 64. To defeat them, the player must approach them from the back and then attack them. Additionally, the Flipside Arcade houses a Boo themed shooting game, Mansion Patrol. This game has the player shooting Boos, including Dark Boos and occasionally Atomic Boos, to score points. A Toad frequently appears to give power-ups, as long as the player saves him from his Boo captor. Lady Bow also makes three cameos in this game.
Paper Mario: Sticker Star
Boos reappear in Paper Mario: Sticker Star. They only appear in World 4-3: The Enigmansion. Mario must use the Book of Sealing, given by a Toad, to seal away every Boo that has escaped. In battle, Boos can make themselves disappear and can slap Mario or they can go up to Mario and scare him by making a scary face. They are able to make Mario dizzy in this game with their scare attack preventing him from using any of his defensive/dodging stickers. The attack is determined by the sound the Boo makes when it disappears.
Among the normal Boos, there is one golden Boo that drops several Coins after Mario defeats it, which can be found in the safe. This Boo attacks exactly like the normal ones. Another notable Boo is one that is crumpled, which is found in a trash can. In battle, it only has 1 HP and cannot attack. Additionally, a group of eighty-two Boos called a Boo Stack also appears. Once all the Boos get returned to the book and it is placed in its rightful spot, Kamek appears and turns all the captured Boos into the mini boss, Big Boo. After defeating the mini-boss, the Boos are put to rest once again and the mansion is restored to its former state. Boos can no longer be fought at this point.
Paper Mario: Color Splash
Boos return in Paper Mario: Color Splash as enemies who can be fought within the parallel world at Vortex Island, Lighthouse Island and Fortune Island. By the time they are first encountered, Mario can instantly defeat them with a hammer First Strike without entering a battle. In battle, they attack by either hitting Mario or scaring him. They can disappear while in battle, causing all attacks to miss until they reappear. Outside of battle, if one is stared at too long, it will disappear, and then reappear behind Mario. A Boo appears as an NPC in Redpepper Crater, where it is in a hot spring. A Boo 10-Stack variant also appears.
Paper Mario: The Origami King
Origami Boos appear as enemies in Paper Mario: The Origami King, first encountered in the Scorching Sandpaper Desert, but only at night; after Mario has explored the Temple of Shrooms and put the sun back in the sky, they are replaced by Koopa Paratroopas. In battle, Boos will turn invisible right before Mario manipulates the arena, forcing him to memorize their positions. However, they will reveal themselves if they are hit by a Toad's thrown object or shortly before time runs out. In addition, much larger Paper Macho Boos appear in the desert at night, replaced by Paper Macho Koopa Paratroopas by day. A Paper Macho Boo is also featured as one of the seven opponents on Scuffle Island.

Outside of battle, they hover around, attacking Mario and Luigi when they are not looking. However, they look away if Mario or Luigi make eye contact. The Boos also show the ability to teleport. In battle, a Boo has two attacks. For the first attack, the Boo will teleport in front of one of the brothers and attempt to bite him. For the second attack, it will fly up into the air and swoop into one of the Mario Bros., which can even prohibit the use of certain moves or items. The former attack can be countered with Mario or Luigi's hammer, whereas the latter can be dodged or countered by jumping. In either of these attacks, if the Boo makes a face, it will target Luigi, if it does not, it will target Mario. Boos are weak to Firebrand and Fire Bros. They also have low HP, but very high defense.
Boos wearing mining helmets and brandishing pickaxes also appear in levels 4 and 5 of Mysterious Mine Carts (levels 3 and 5 in the remake). If these Boos touch Mario, they will cause the loss of a diamond. They will slowly shrink until they disappear if the flashlight is pointed at them.

The Boo reappears behind the corresponding bro and charges from behind; this can be avoided or countered with a jump. Boos also appear during the battle with Sunnycide. While flipped on its back, Sunnycide can summon a Boo to attack Mario or Luigi, which can be countered with a hammer.

When Bowser gets to have a feast as a reward for beating Midbus at the Fawful Theater show, three Boos serve him food cooked by Fawful himself. However, Bowser is tricked into eating too much food and ends up getting fat, which results in him getting stuck in the floor due to his weight. Boos reappear later in the game to help many of the brainwashed minions of Bowser push the Fawful statue against him. In addition, a Boo appears whenever Bowser gets a level up. The Boo (just like the Fishin' Lakitu in Mario's or Luigi's level up screen) holds the circle for getting a bonus upgrade for the stat of the player's choice.
An odd thing shown in the game is a Boo and Koopa Troopa in love with each other in Bowser's Castle. They not only love each other, but also love Fawful due to the brainwashing that was put on the minions.
Yikk, a ghost who appears in the same game at the Tower of Yikk, explains that he researches Boos. He even builds a machine to visualize Boo transparency waves before he passed away.
During the fight with Bowser Memory ML, Bowser Memory L has an attack that involves a digital Boo chasing him around. The Boo can be jumped on by either Mario or Luigi to stop the attack prematurely.

Dr. Mario World
Boos are assistants in Dr. Mario World as of October 31, 2019. Its effect in stage mode is to fill the skill meter faster when yellow viruses are eliminated, where it fills more at higher levels. The percentage determines the number of points the skill meter fills, so for example at level 3, it fills 30% faster, meaning that for each yellow virus eliminated, an extra 0.3 points is added to the skill meter. In versus mode, its effect is to increase the speed the skill meter fills for both the user and their opponent, in which the amount of points required to fill the skill meter is reduced by the listed percentage. If both players use this assistant, the effect stacks. The resulting amount of points required to fill the skill meter is rounded down to the nearest round number.
A Boo was added as a doctor under the name Dr. Boo on September 24, 2020. His skill is represented by the Boo shielding his face, after which he shows his face and tongue. In stage mode, he immediately eliminates objects in a random 2 x 2 area, similar to Dr. Fire Rosalina's skill but it affects a smaller area. In versus mode, he eliminates objects in a 1 x 1 area at level 1, a 2 x 2 area at level 2 and a 3 x 3 area at level 3 to 5 (the skill meter fills faster at higher levels). This skill prioritizes areas that contain viruses, but if there are no more viruses, the area in which is targeted will be random as long as it contains at least one object.
Other appearances
The Legend of Zelda: Link's Awakening
- Zelda Wiki article: Boo
Boos in The Legend of Zelda: Link's Awakening only appearing in a dark room in the games' second dungeon, Bottle Grotto. They actively chase Link regardless of whether he is facing them or not; if Links swings his sword at them, they disappear and reappear at a different location. After Link lights up the room, they become vulnerable and can then be defeated with Magic Powder. In the Nintendo Switch remake of the game, they now use their voice clips from the Super Mario franchise, and a Boo figure can be won from the Trendy Game after clearing the Key Cavern and placed in the Quadruples' house. The text that appears upon acquiring the figure reads, "You got a Boo figure! As spooky ghosts go, this one's pretty cute!"
Minecraft
Additionally, in the Super Mario Mash-up in Minecraft, Ghasts are replaced by Boos.
Monopoly Gamer
Boo is a playable character in Monopoly Gamer. It is sold separately as a "Power Pack" expansion figure.
Unused appearances
Super Mario Odyssey
Boos were going to appear physically in Super Mario Odyssey, as one is seen in concept art for the game, but they were removed from the game,[35] making this game the first game in the Super Mario series to not contain Boos since Super Mario Land. However, Peach wears a Boo mask on the side of her head when she visits Bowser's Kingdom, a common way to wear masks of yōkai in festivals in Japan.
The Super Mario Bros. Movie
Boos were planned to appear in the film, as they can be seen in early concept artwork for the Dark Lands, but they were removed from the final release.[36] However, their leader, King Boo, makes an appearance during the wedding between Bowser and Peach.
General information
Physical appearance
Though their specifics change from game to game, Boos are usually bashful, cowardly, spherical ghosts. They have black beady eyes and fangs. Although they are typically white, there are sub-species of the Boo race that appear in different colors, such as pink. From Luigi's Mansion onward, it became common to picture Boos sticking out their tongues. Boos often have wide open grinning mouths with their tongue sticking out. In most games, Boos are unable to change their facial expressions. The only exception is when they are looked at, in which case they bashfully cover their faces along with the section around their eyes blushing red or pink. However, the Luigi's Mansion and early Paper Mario games portray Boos as being more expressive than in other games, being able to frown, scowl, or even smirk. Since Super Mario 64, Boos have been portrayed with a unique, high-pitched laugh. Both this laugh and Bowser's laugh are derived from the same stock recording of a human man laughing recorded by Charles Martinet;[37] it was sped up for the Boos and slowed down for Bowser. However, Boos received a new laugh starting in Mario Power Tennis, being more of a haunting laugh than before. Although most species of Boo will cover their faces and become intangible when looked at, they will often sneak behind their victim and strike when their back is turned. Due to their ghostly abilities, Boos are generally invulnerable and cannot be harmed by ordinary means of attack. Despite this, they are not invincible and are especially vulnerable to the light. If they are exposed to a source of light, Boos are usually weakened, and in some cases, they may even be defeated. Usually, they can also have other weaknesses. Because of their intolerance to the light, Boos will often hide if they are trapped in lit rooms. However, King Boo claims that Boos cannot truly be killed. While the ghosts generally appear to be more afraid of their victims than their victim is of them, this is not always the case. Some Boos have absolutely no problem meeting their victim's gaze, and will even try to attack. Boos tend to have a taste for the fine arts, as seen in Paper Mario and Mario Party 4. In Luigi's Mansion: Dark Moon it is shown that Boos will actually save someone if only later to trick them. This is seen when Luigi watches through pipe in the Old Clockworks as a Yellow Toad balances on a ledge. Some Boos appear and watch the Toad before it falls off the ledge, which is later found to be quite a drop, the Boos show a large amount of concern and shock when this happens before diving down for the Toad. The Toad is later found in a painting because of the Boos.
Boos are often characterized by their sub-species despite their similarities in appearance and attack manner. Boo species tend to vary wildly in size, with some such as Boo Buddies being miniature, while others such as the Big Boos boast gigantic size.
In Luigi's Mansion, Professor E. Gadd notes that Boos have mysterious powers that increase when they gather together in large groups. While it is difficult to stop them, they can be weakened if one is able to defeat members of the group. Although in Luigi's Mansion: Dark Moon this does not seem to affect them or King Boo in any way suggesting that they do not always need to be in groups anymore.
Boos have few predators, their only known threat being a Spike named Tubba Blubba in Paper Mario, when he began devouring Boos. This, however, may have been his revenge for the countless times the ghosts scared him.

Habitat
Boos typically make their homes in dark forests, such as the Forever Forest and Boo Woods, and tend to be most commonly found in older buildings such as mansions, castles, and Ghost Houses. Although most of them live in such dwellings, they also seem to enjoy wastelands. One of the only known Boo villages lies in Gusty Gulch.
They are typically found in groups because their fears make them find strength in big numbers.
Allegiance
Though most Boos tend to side with Bowser and King Boo, they seem to, for the most part, actually stand as neutral. For example, Boos are by now a common enemy in most side-scrolling games; however, in the Paper Mario series and now increasingly in the multiplayer games, Boos have been seen to take the side of the Mushroom Kingdom. Lady Bow, in fact, helped Mario save the kingdom in Paper Mario. In another example, the Boos in the Creepy Steeple from Paper Mario: The Thousand-Year Door attack Mario initially, but later in the game Mario is sent a friendly letter from one of them. King Boo, on the other hand, has several times been shown to wish nothing but terrible things for the heroes, but especially Luigi (although this could be accredited to Luigi being easily scared, making him a prime target for most Boo antics). They also have attacked Bowser in some games, such as the Mario Party series, mainly from Mario Party 5 to Mario Party 8.
Language
As hinted in the game Super Mario Galaxy, Boos have their own unique language called Booish. It most probably is spoken only by Boos since Mario cannot understand it. However, upon absorbing a Boo Mushroom and turning into Boo Mario, he gains the ability to read it, if not speak it as well.
Paper Mario also features Boos replacing certain words with "Boo", possibly as a part of the Booish language:
I am so bored!! Boo-ored!
Boo-st of luck!
Hey, what can I Boo for you?
It's going to be the most Boo-tiful wedding ever!
