Shy Guy

"Run! Run for it!"

- Shy Guy

Shy Guys (originally spelled Shyguys and alternatively formatted as Shy-Guys ) are timid troublemakers and common enemies in the Mario and Yoshi series. They are recognizable by their masks, which they wear due to their shyness. They made their first appearance in Yume Kōjō: Doki Doki Panic, a non-Mario game; they were later carried over to the Mario universe when Super Mario Bros. 2 was created. They are voiced by Treehouse member Nate Bihldorff.

Super Mario Bros. 2
Shy Guys make their first Mario game appearance in Super Mario Bros. 2, although the Shy Guys' real first appearance is in Yume Kōjō: Doki Doki Panic. In this game, Shy Guys, along with the other 8 bits, help Wart conquer Subcon. Shy Guys are the most common enemies that the four heroes meet. They attack Mario, Luigi, Toad, and Princess Toadstool by walking in their general direction. They can be easily disposed by being picked up and thrown against another enemy or into a nearby pit. They can also be defeated by having an object thrown at them.

Red Shy Guys walk off ledges while pink ones don't, striking a resemblance to Green and Red Koopa Troopas respectively, although the primary difference is that Red Shy Guys are known to turn in the direction of the player after landing. Red ones are also known to ride Autobombs and Ostros and often appear out of Vases. Pink ones became blue in the remakes of Super Mario Bros. 2. The Super Mario Advance remake introduces Mega Guys. It takes time to pick them up because of their size. If the player picks up a Mega Guy and throws it to the ground, or defeats it, it drops a Heart.

Super Mario Maker
Actual Shy Guys are not seen in Super Mario Maker, but one of the unlockable costumes for the Mystery Mushroom is that of a Shy Guy in its Super Mario Bros. 2 appearance. This costume is unlocked at random if the player completes the 100 Mario Challenge on any difficulty, and after getting unlocked, the costume can only be used on Mario in Super Mario Bros. style. Sound effects are also reused from Super Mario Bros. 2 and some spin-off games.

The Super Mario Bros. Super Show!
In The Super Mario Bros. Super Show!, Shy Guys make appearances as antagonists, working for King Koopa. Like most other minions of King Koopa, they wear costumes to go with the theme of each episode.

Nintendo Comics System
Shy Guys appeared commonly in issues of Nintendo Comics System, where they were depicted as somewhat disgruntled soldiers of Bowser. Along with Koopa Troopas, they appeared to be the most common minions.

Nintendo Adventure Books
Some Shy Guys and their GLOM-created sand clones appear throughout Double Trouble, but are never directly fought by Mario, who decides it is best to just ignore or avoid them.

In Leaping Lizards, some Shy Guys are spotted among the crowds attending the International Mushroom Games. Upon entering a chamber in a cave in Koopa Capers, Luigi wonders why he is suddenly "shivering like a Shy Guy" before realizing how unusually cold the room is.

In Pipe Down!, Mario and Luigi can encounter a Shy Guy hopping through the Koopahari Desert, leaving footprints in the sand that look like the indentations left by the basketball Princess Toadstool was dribbling when she disappeared. In an elevator in the Mushroom Palace, if a lever with a mushroom printed on it is pulled, some Shy Guys, Tweeters and Cheep Cheeps swarm Mario and Luigi, leading to a Game Over.

In Dinosaur Dilemma, Mario and Yoshi can encounter some Shy Guys, but evade the enemies by just hopping over them. In Unjust Desserts, some Shy Guys are among the enemies Bowser has Magikoopa shrink and send after the shrunken Mario, who had made himself tiny in order to enter Yoshi's body and rescue the eaten Luigi.

In Brain Drain, a group of Shy Guys ambushes Luigi if he decides to follow Princess Toadstool after arriving at Dinosaur Island. Luigi can also spot some Shy Guys holding up the lunch line (due to their mumbling) in Iggy Koopa's lair, and in the WMUSH radio station after Iggy takes it over.

Super Mario World 2: Yoshi's Island / Super Mario Advance 3
Shy Guys' first chronological and true Mario appearance is in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3, where their name is hyphenated. Here they are extremely common and weak enemies, simply walking or flipping forward to occasionally stop and look left and right. They sometimes appear out of Pipes unless Yoshi has a full six eggs. The colors they come in are red, yellow, green, and magenta and have different colored mask straps. Boo Guys, as well as other variants, also first appear in this game. Like other enemies, they can be defeated by jumping on them, although they will respawn when Yoshi leaves the area and returns. In addition, they can be eaten and turned into eggs, which prevents them from respawning. In dark levels of the game, it is revealed that their shoes glow in the dark.

Tetris Attack
Shy Guys appear to be allies with Raphael the Raven in Tetris Attack. A spell was cast on all of them to work for Bowser. They appear in the 8th level, and are saved by Yoshi. It is unknown what happened to these "brave" Shy Guys after the events of the game. It is unknown if these Shy Guys actually serve anyone or are free Shy Guys.

Yoshi's Story


In Yoshi's Story, Shy Guys are once again common enemies, walking forward and backward. Woozy Guys from Super Mario World 2: Yoshi's Island are not present, but have their places taken by more varieties. Some Shy Guys carry Fruit or hide in trees. To defeat Shy Guys that are in trees, Yoshi must Ground Pound near the tree they are hiding in, causing them to fall out. Additionally, if Yoshi Ground Pounds near a Shy Guy, its color changes, although the reason for this change is unknown. If Yoshi ground pounds near a Shy Guy while affected by a Heart Fruit, the Shy Guy turns into a lucky fruit.

If a Yoshi eats a Shy Guy of matching color, it is awarded with three petals on the Smile Meter instead of one. Additionally, when a Baby Yoshi eats a Shy Guy, the Yoshi Egg that is produced is the same color as the Shy Guy. This game also introduces the first "good" Shy Guy, the White Shy Guy, as well as the more deadly Black Shy Guys. Shy Guys have voices in this game and can be distinctly heard saying "Heiho" (their Japanese name), along with other sounds.

Yoshi Touch & Go
Shy Guys reappear in Yoshi Touch & Go. They are vulnerable to all attacks and are worth a Yellow Coin. In this game, like all the other enemies, bumping into a Shy Guy causes an instant Game Over. Shy Guy serves the same purpose in this game as in the previous, as working as a common soldier for Baby Bowser. Many varieties of Shy Guy appear on the island, red being the most common. Balloon Shy Guys were introduced in this game as a sub-species.

Yoshi's Island DS
Shy Guys also appear in Yoshi's Island DS, once again, as very common and weak enemies. Yoshi can use any tactic to defeat them: jumping, egg-throwing, or swallowing. While Shy Guys in this game play virtually the same role as they did in Yoshi's Island, there is a boss known as Big Guy the Stilted, a massive robot seemingly built by Shy Guys.

Other than being common enemies, Shy Guys also have their own section in the Island Museum. Yoshi can view the different types of Shy Guys in that section, though Shy Guys that do not wander on land, such as Toober Guys, are only in the marine section.

All of the colors from the original Super Mario World 2: Yoshi's Island, including blue and excluding magenta, appear in this game.

Yoshi's New Island
Shy Guys appear as enemies in Yoshi's New Island, where they simply walk around, like in the past games. Mega Guys appear, turning into Mega Eggdozers if swallowed by a Yoshi. New species include Metal Guy, which turns into a Metal Eggdozer if a Yoshi swallows it, as well as Door Heihō and Tree Heihō. In addition, a Fake Yoshi is a Shy Guy in disguise.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
Shy Guys appear in the game Yoshi's Woolly World and Poochy & Yoshi's Woolly World, acting as they do in previous Yoshi games. If they are eaten, they are unraveled and turned into Yarn Balls; their masks also come off. Two new sub-species of Shy Guy are introduced in this game: Bomb Guys and Pharaoh Guys. In King Bowser's Castle, Yoshi must obtain Yarn Balls from Shy Guys of four different colors and use each to wrap one of the four statues at a large entrance to open it. However, only a few of the necessary Shy Guys appear among a multitude of black ones.

Super Mario Adventures
In Super Mario Adventures, a Shy Guy, along with a Snifit and Flurry, appeared as an attendee of Bowser's wedding to Princess Toadstool.

Super Mario RPG: Legend of the Seven Stars
"Hold still, okay?!"

- Shy Guy

In Super Mario RPG: Legend of the Seven Stars, Shy Guys riding pogo sticks, under the name Shysters, work for the Smithy Gang. They helped Mack to invade the Mushroom Kingdom and the castle. Stronger versions of Shysters named Shypers and Springers are also found in the alternate dimension of Smithy's Factory.

More traditional Shy Guys also appear throughout the world of the game, at places such as the Rose Way, where they sit on top of Treasure Boxes, manned Boards, or fought alongside Lakitus that lower them towards Mario and Mallow with a fishing pole. Sling Shys, stronger versions of the traditional Shy Guys, also work for Valentina in Nimbus Land. The rare Shy Rangers also often lurk the undergrounds of Pipe Vault.

He created the board because he wants to go an adventure, but isn't brave enough to go on his own. Whenever he talks, he appears to be nervous and meek.

Paper Mario
"Oh no... Poor me..."

- Shy Guy

Shy Guys, as well as several variations of them, are semi-common enemies in Paper Mario. After Mario returns from Forever Forest, he finds Toad Town overrun by Shy Guys. He can hit the enemies with his Hammer to make them run out of town. Once Mario discovers Shy Guy's Toy Box, the secret hide-out of the Shy Guys, they can be fought as normal enemies. They have two main attacks: They can simply tackle Mario for 2 damage, or they can do an acrobatic attack, dealing 3 points of damage and bowing to an unseen but not unheard crowd.

There are five different color variations of the normal Shy Guy, although there is no actual difference between any of them.

This game also features Groove Guys, Shy Guys that make Mario dizzy; Sky Guys, Shy Guys that have balloons to keep them in the air; Medi Guys, Shy Guys that heal any ally; Spy Guys, Shy Guys that wear camouflage gear; Pyro Guys from Super Mario World 2: Yoshi's Island; and the strongest of a Shy Guy known as the Anti Guy, three of which appear in Bowser's Castle if the player answers three questions incorrectly during the quiz with the Guard Door.

They can also be found on Lavalava Island when Spear Guys shed their armor.

It is revealed that Shy Guys have their own language called Shy Guy that only Russ T. can understand.

During the ending cinema of the game some Shy Guys can be seen talking with Watt, a baby Li'l Sparky. They can also be seen on General Guy's parade float, dancing. Also, the Shy Guys' parade float in the ending have "Heihos" ("Heiho" being Shy Guy's Japanese name) written on both the left and right of General Guy.

Paper Mario: The Thousand-Year Door
Although Shy Guys were not actual enemies in Paper Mario: The Thousand-Year Door, they do appear in the Audience of most of the battles, and a few statues of Shy Guys also appear on the Poshley Heights fountain. Occasionally, if part of the audience, Shy Guys run onto the backstage and cause pieces of the set to fall on Mario or his enemies. This is also used to signal the first occurrence of a stage hazard (like fog, ice, fire, etc.). Shy Guys give Mario Star Power along with the other audience members when he performs a move correctly. The name Heihoo, which is Japanese for "Shy Guy," appears alongside other scrapped enemy names (among which are also Faia Heihoo "Fire Shy Guy", Komando Heihoo "Commando Shy Guy", and Burakku Heihoo "Black Shy Guy") in Paper Mario: The Thousand-Year Door's coding, suggesting that Shy Guys were once going to appear as enemies in that game.

The X-Nauts somewhat take a role of Shy Guys, as their commander, Lord Crump, gets inside a machine that very slightly resembles General Guy's tank (except with arms and legs). In addition, when the X-Nauts are fleeing from the Great Tree, one of them falls over, mirroring the straggler Shy Guy in the Shy Squad in the first Paper Mario. Additionally, X-Nauts make formations similar to the Shy Squad and others when attacking Mario during the ship battle between Crump and Cortez, and they are fought before Crump himself is faced.

A Shy Guy may also appear when the Special move Clock Out is used. When this happens it tries to prevent Mario from immobilizing his enemies.

Super Paper Mario
Shy Guys solely appear in the audience of Super Paper Mario when a Stylish Move is performed. Sprites for them are also among the unused data in the game. They, along with Wigglers, Fly Guys, Spear Guys, Stilt Guys, and Monty Moles, were removed for unknown reasons during the game's production.

Paper Mario: Sticker Star
Shy Guys appear in Paper Mario: Sticker Star with their Super Paper Mario appearance, although their feet are more within their robes. They only appear in World 3 and World 4. In battle, a Shy Guy's only attack is running up to Mario and flailing its arms at him. Sometimes, the Shy Guy might trip before reaching Mario, cancelling the attacks. Also, if Mario uses a Tail Sticker, the Shy Guy pushes Mario and try to steal the sticker. A Shy Guy can also knock away one of Mario's attacks if he uses the Battle Spinner that causes the Shy Guy to take up its turn. Along with standard Shy Guys, Mariachi Guys appear. There are also Shy Guys holding paper clips, known as Clip Guys, and Paint Guys, who hold a bucket of paint. Both of these enemies can assist a Shy Guy in battle. Additionally, Spear Guys and Snifits also appear in the game. Additionally, two Shy Guys are found harassing the Traveling Toad in World 4-6. They are very powerful, similar to Anti Guys, each having 120 HP and an attack power of 7. When defeated, they drop a Secret Door sticker. Unlike Snifits, Shy Guys take damage from staying in poison too long in battle and try to find unpoisoned ground.

Paper Mario: Color Splash
Shy Guys are the most common enemies in Paper Mario: Color Splash, as Slurp Guys are responsible for draining the colors in Prism Island. Shy Guys appear in different forms, such as Paint Guys, Sombrero Guys, Spike Guys, Soggy Guys and Coal Guys. There is also one Shy Guy that Mario talks to on the Sunset Express that Mario later unknowingly battles.

Mario Tennis series
A Shy Guy is an unlockable character in Mario Tennis for the Nintendo 64 (where he is unlocked after the Star Cup is won in Singles). This is Shy Guy's first playable appearance. It is a Technique character, and during its trophy ceremony it turns into a Fly Guy and starts flying around. Shy Guy comes back for another round of tennis in Mario Power Tennis, but this time it is available from the start. Once again, it is a Technique character. For its Offensive Power Shot, it turns into a Spear Guy and electrifies the ball. For its Defensive Power Shot, it turns into a Spear Guy, but this time it extends its spear to hit the ball. When it wins a Singles Tournament, it walks up to the podium where the trophy is while Luigi is there applauding it. Accidentally, Shy Guy trips on a step to the stage and its mask falls off. Shy Guy's appearance without its mask is not shown to the viewers, but Luigi gets astonished by it. Shy Guy quickly puts its mask back on, takes the trophy and walks off the stage. In Mario Tennis Open, Shy Guys are line judges in the Wario Dunes court.

In Mario Tennis Aces, Shy Guys appear as audience members. They also appear as a stage hazard on Snowfall Mountain, where they run across the stage to interfere.

In the game's version 2 update, Shy Guy is added as a playable character, where he returns as a Technical character.

Super Smash Bros. Melee

Mario Baseball series
"IT'S HORRIBLE! HIDE THE CHILDREN! LOCK THE DOORS! BOLT THE WINDOWS!"

- Shy Guy

Shy Guys of all different colors are playable in Mario Superstar Baseball. They are balanced characters. Ironically, their starting captain is Yoshi, one of their earliest enemies. They appear in Mario Super Sluggers, still on Yoshi's team.

In Mario Super Sluggers, all the Shy Guys have their fielding skills boosted a few levels, with the Black Shy Guy showing the best fielding abilities. Their batting ranges from average to low, their pitching is weak and their running is generally slow.

Regarding chemistry, in Mario Superstar Baseball, Shy Guys show good chemistry with Birdo and Monty Mole, while showing bad chemistry with Baby Mario and Baby Luigi. In Mario Super Sluggers, the Shy Guys maintain their good chemistry with Birdo and Monty Mole, but they also display good chemistry with Boo. Their bad chemistry is also expanded to include their relationships with Yoshi and the Yoshi species, as well as Baby Mario, Baby Luigi, Baby Peach, Baby Daisy and Baby DK.

Mario Strikers Charged
Shy Guys appear as sidekicks in Mario Strikers Charged. They are balanced players. Their skillshot is the Bullet Bill Blast. When given enough time, a Shy Guy charges fully before riding a fast Bullet Bill aimed right at the goalie. When this move is performed, the goalkeeper and all players near him (including the Shy Guy) are temporarily stunned. Shy Guy gets up more quickly than the other teammates, however, so he may quickly get to the ball and score. Other allies not affected by the blast may take the ball and score as well. Alternatively, an opposing player trailing the Bullet Bill at a safe distance may sweep through and pass the ball downfield to one of their teammates.

When Shy Guy scores, sometimes it runs, trips, and its mask falls off, similar to the Mario Power Tennis trophy award. While this seems to confirm that Shy Guys' masks are not their actual faces, various other scenes show that the mask is capable of different facial expressions, such as a happy face and a mad face.

Mario & Sonic at the Olympic Games
Shy Guy is a referee in the Wii/DS crossover, Mario & Sonic at the Olympic Games. Shy Guy is seen in his normal outfit of red robes and randomly hosts events with a cast of other Mario and Sonic Characters.

They also appear in the crowd of Wario Factory in multiple colors.

NES Remix series
Shy Guys are featured in challenges based around Super Mario Bros. 2 from NES Remix 2 and Ultimate NES Remix. The player usually has to either defeat or dodge these enemies in order to advance. In NES Remix 2, Shy Guys are present in all stages but in the third, ninth, eleventh, and twelfth ones. Since these challenges are sequences from a port that is identical to the original game, Shy Guys retain their exact appearance from there.

Captain Toad: Treasure Tracker
Shy Guys appear as enemies in Captain Toad: Treasure Tracker. Like Goombas in 3D Mario games, they chase after Captain Toad or Toadette upon seeing either one of them, but get tired and stop after a while. However, in dark levels, they can also start to chase the protagonist should they shine their headlamp on them. In the game box art, their robe's texture appear to be normal, but in-game, it appears to be made of wool instead of tissue or silk. Two types of Shy Guys appear: blue stationary Shy Guys that periodically turn 90° and red Shy Guys that walk along paths.

The Legend of Zelda: Link's Awakening
In The Legend of Zelda: Link's Awakening, Shy Guys appear as enemies, known as Mask-Mimics in the English versions of the game. In this game, they do not directly attack, and instead mimic Link's movements in reverse. Their mask protects them from frontal attacks from Link's blade, so the only means to defeat them is to strike them when their back is turned by using a Spin Attack. While the original game was in monochrome, in the DX version of the game, they are colored red.

Sonic Lost World
Shy Guys appear alongside a few enemies from Super Mario World 2: Yoshi's Island in Sonic Lost World as enemies in Yoshi's Island, dubbed as "Yoshi's Island Zone" in-game.

Allegiance
Shy Guys first appear in Super Mario Bros. 2, where they are minions of the mischievous Wart. However, their first appearance chronologically is in Super Mario World 2: Yoshi's Island, where they are members of the Koopa Troop.

Since Super Mario Bros. 2, Shy Guys have been seen working for many other villains, including Smithy, Donkey Kong, Wingo, and Kamek. One Shy Guy (the White Shy Guy) is actually an ally of Yoshi. It can be assumed that Shy Guys never have had a true allegiance.

Physical appearance
All Shy Guys (with the minor exception of some Shy Guys from Mario Strikers Charged) wear robes that can be red, pink, blue, light blue, yellow, orange, green, black, gray, or white. They are all fairly short and wear masks with holes on them that represent eyes and a mouth. It is unknown what is behind these masks. However, in Shy Guy's trophy celebration movie in Mario Power Tennis, after Shy Guy trips on one of the steps, his mask falls off, and Luigi sees its face without his mask on and is shocked at the sight. The Shy Guy then quickly puts the mask back on and picks the trophy up, showing it to the audience. Sometimes, when Shy Guy's mask falls off, what appears to be a mask strap tends to stay on its head. Also, in Luigi's Mansion, Luigi can use the Poltergust 3000 to pull a mask off a Ghost Guy. Ghost Guys do not have eyes on their masks, but their faces are pure blackness with two glowing yellow eyes where the mask's eyes would be. It is unknown whether this is what a Shy Guy's face looks like when it is alive, as they, like the game's other generic ghosts, were imitations created by Vincent Van Gore. Additionally, in Paper Mario: Color Splash, a Shy Guy in the Golden Coliseum says that Mario would make a terrible Shy Guy because he has a face, implying that Shy Guys do not have a face.

It is also possible that the Shy Guys' so-called "masks" are not masks at all, but rather faces. In Yoshi's Island DS, the sleeping Shy Guy's mask eye holes are closed, supporting this. Also, the Bandit sub-species of Shy Guy have been shown to have the ability to change the expressions on their masks as if they were their actual faces. The picture shown when Bandit wins in Super Mario World 2: Yoshi's Island Mini-Battles even suggests that he is able to stick out his tongue. Also, Super Mario RPG: Legend of the Seven Stars ' s Shy Guys' eye holes comically spin when the Shy Guy is confused, much like people's eyes do in cartoon gags; the Shy Guys of Super Mario RPG are also able to blush on their masks. Spear Guys and Dancing Spear Guys are perfectly capable of moving their mouth holes when chanting and singing, as Super Mario World 2: Yoshi's Island shows, while Boo Guys are shown regularly changing their expressions and blinking. Most recently, in Mario Strikers Charged, Shy Guys have been shown to yet again be perfectly able to change the expressions on their masks.

Some early Super Mario Bros. 2 artwork of Shy Guys, as well as The Super Mario Bros. Super Show!, depicted Shy Guys as wearing mask-like badges depicting an angry face, similar to that of Phanto. It is unknown what this badge represents, but it is possible that it is an emblem of the 8 bits. Another Shy Guy-related element seen only in Super Mario Bros. 2. and The Super Mario Bros. Super Show! are also notable for using game artwork of the earliest forms of Shy Guys, making them tall, stout, and human-like; however, the appearance of Shy Guys was later redesigned to their in-game sprite appearance in Super Mario Bros. 2.

In the first few episodes of The Super Mario Bros. Super Show!, Shy Guys were depicted as being similar in appearance to their game counterparts, though with one large exception - their masks possessed only two holes. They only had eye holes perpetually in a scowling position. Later episodes of the show have Shy Guys resembling their game versions more with three holes in their mask, all of which were perfectly circular.

Even though Shy Guys appear to be short, squat humanoids, a screenshot from the game Captain Toad: Treasure Tracker shows that they appear to have stick-like legs under their robes. Their legs can also be seen in Mario Kart 8 when winning first place in a race.
