'''''Mario Super Sluggers''''' is the [[Wii]] follow-up to the 2005 [[Nintendo GameCube]] game ''[[Mario Superstar Baseball]]'', and the second game in the ''[[Mario Baseball (series)|Mario Baseball]]'' series. This game borrows many elements from the previous game, but it also includes new elements, including a variety of gameplay controls, such as taking advantage of the motion sensor controls that the [[Wii#Wii Remote|Wii Remote]] provides. The game also has a more in-depth and more narrative-driven Challenge Mode, where, rather than only facing off against a Team Captain and a team of opponents, players interact with more characters, including a variety of various sub-characters, and play various small challenges to recruit them for their team. Up to four players can play this title, and a new feature is that players can choose which of the two team sides to be on.

''Mario Super Sluggers'' was released in Japan and the Americas in 2008, and had a [[Nintendo Selects#Wii|Nintendo Selects]] re-release in the Americas in 2011. It is the only ''[[Super Mario (franchise)|Super Mario]]'' game for the Wii that was never released in Europe and Australia in physical form. The game was re-released on the [[Wii U]] [[Nintendo eShop#Wii U|eShop]] in the Americas on March 31, 2016, and in Japan on August 17, 2016; however, it was eventually removed after its discontinuation on March 27, 2023.
==Gameplay==
[[File:MSScontrols.jpg|thumb|400px|The three control types, as shown in the instruction booklet enclosed with the game.]]
''Mario Super Sluggers'' can be played using three different control methods:
*Wii Remote (vertical)
*Wii Remote (horizontal)
*Wii Remote + Nunchuk controller

Before a game starts, a roulette will start in order to show which team will be batting first. This is different from the previous game, in which the player could choose which team would be batting first.

Assuming that players are using the Wii Remote (vertical) or the Wii Remote/Nunchuk combination, in order to bat or pitch, players must hold the {{button|wii|A}} button and the Wii Remote must be swung at the appropriate time. The more precise the hit/pitch, the further/faster the ball will go. To charge up a pitch or swing, players must pull the Wii Remote back. They can also do curve balls as well by twisting the Wii Remote, while pitching. Once the ball is in a fielder's hand, the Wii Remote must be swung so that the fielder can pitch the ball at one of the basemen.

In the outfield, players can create special moves if there is chemistry between outfielders:
*One outfielder tackles the ball and the ball rolls towards the outfielder with chemistry. The outfielder that holds the ball can then throw a very fast ball towards a base from the outfield.
*When a possible home run is hit, players can initiate a Buddy Jump. Upon jumping around another outfielder's head and pressing {{button|wii|A}} twice, one of the players will jump incredibly high to catch home run balls. This must be done with precise timing.

Superstar Matchups return; however, it is set for captains only and occurs when the team captain is not batting first and when one runner is on second or third and two or all three runners on base (only when the runs exceed to 4 or more on the scoreboard). This also applies to RBI chance screens.

[[File:Wario-Fatigue-MSS.png|thumb|300px|left|While pitching, a character may show signs of fatigue, depending on how long they pitch. Letting up a lot of runs or using many Star Pitches factors into this, too.]]
While pitching, however, players will have to pay attention to the pitcher's stamina. If the character that's pitching is showing signs of fatigue (depicted by a water droplet in a bubble), their pitches will start to behave in an erratic manner. When the current pitcher has fatigue, players will have to decide to adjust the defense so that a new character plays pitcher instead. On a side note, pitchers can get exhausted even quicker if the batting team manages to make a lot of successful Home Runs. Even a Grand Slam can cause a pitcher to become fully fatigued right off the bat.

[[Star Skill]]s make a reappearance in ''Mario Super Sluggers'' as well. Any player can pitch or bat using Star Skills, however, only '''Team Captains''' can use special hits/pitches. '''Team Players''' can only use Star Skills that will make the ball go faster or slower. Both teams can store up to five Star Skill attempts; they are earned as a result of well executed plays.

[[File:Mario-MVP-MSS.png|thumb|300px|[[Mario]] wins MVP after his team (Luigi, Peach, Red Toad, Purple Toad, Toadette, Red Yoshi, Red Noki, and Red Pianta) wins against the [[Wario Muscles]].]]
At the end of each game, the character who has had the most potential for their team will win the MVP award, which will be recorded in the Records menu. Characters can earn MVP points by striking out opponents, executing nice plays on defense, successful hits while batting (the batter has to make it to 1st base without getting out), stealing bases, close plays, and even for error item usage. The character with the most MVP points will win the award. Also, it's possible for more than one character to win MVP if at least two characters have the same amount of points.

==Venues==
There are a total of nine stadiums (excluding Toy Field) in all. Every Team Captain (excluding Waluigi, Birdo, and Diddy Kong) has a stadium which is based on their character's unique persona. [[Mario Stadium (baseball stadium)|Mario Stadium]] is the only one not to feature any gimmicks in the field, making for the most realistic baseball experience. Six of the nine stadiums can be played in daytime or nighttime, which cause different changes in gameplay depending on the stadium (except for Mario Stadium, where the difference is only aesthetic). The time of day can be changed by pressing either the sun or the moon on the stadium selection menu. The [[Bowser Jr. Playroom]] is only accessible during the day, while [[Luigi's Mansion (baseball stadium)|Luigi's Mansion]] and [[Bowser Castle (baseball stadium)|Bowser Castle]] can only be accessed at night.
===Starting venues===
These stadiums are accessible when starting a new game file.

All of the captains and main team players from ''[[Mario Superstar Baseball]]'' make a return appearance in ''Mario Super Sluggers''. In addition, [[Baby Peach]], [[Baby Daisy]], [[Baby DK]], [[Funky Kong]], [[Tiny Kong]], [[King K. Rool]], [[Kritter]], [[Wiggler]], and [[Blooper]] have been added as new main team players. It is now possible to put more than one of the same character on the team in Exhibition Mode, as long as they are different colors. However, it is no longer possible to choose which hand that the characters will bat and pitch with; for example, players can no longer make Mario a left-handed batter.

Players are given the choice to play as their [[Mii]]s as well, whose stats are all 6/10. Players cannot choose to have a whole team of nine Miis, but they can put one captain and up to eight other Miis.

When characters become '''Star Players''', their abilities are boosted by one point each. However, characters can only become Star Players by defeating Bowser's team in Challenge Mode, with the exception of Miis.

If one counts the alternate team players and the Miis, ''Mario Super Sluggers'' has the second most playable characters of any ''Super Mario'' game, behind ''[[Mario Kart Tour]]'', with a total of 72 playable characters.
===Team captains===
All team captains listed below in this section are available to be selected in the game's Exhibition Mode. [[Luigi]], [[Princess Daisy|Daisy]], [[Birdo]], [[Waluigi]], [[Diddy Kong]], [[Bowser]], and [[Bowser Jr.]] are only selectable as Team Captains ''outside'' of Challenge Mode. Depending on progress made in the Challenge Mode gameplay itself, players are only able to choose [[Mario]], [[Princess Peach|Peach]], [[Yoshi]], [[Wario]], and [[Donkey Kong]] while navigating the [[Baseball Kingdom]].

===Team players===
From the start of each new game file, only the returning characters and [[Mii]]s are available from the start in Exhibition Mode, and none of them are available at the start of Challenge Mode. For the majority of these cases, the player usually has to go through the Challenge Mode process and find the unlockable Team Players in question. Upon finding them, the player is given tasks in relation to them including specified Scouting Missions or Battle Missions. Once the tasks are completed successfully the Team Players are unlocked for use in other modes for the game such as during the Exhibition Mode.

Certain new Team Players can also be unlocked by playing the other available modes in the game. These Team Players are added to the overall roster for the entire game, once certain conditions are met.

Note: Although the game states that Petey Piranha throws with his right hand, he does not use his arms to field or throw the baseball.

==Chemistry==
{{main|Chemistry}}
Like ''[[Mario Superstar Baseball]]'', the characters will have good and bad relations with any other character. However, the characters can make special abilities with another character when they show good [[Chemistry]]. The player can receive items with chemistry while batting. If the player is a batter and the next batter shares chemistry with the player, this will result in getting an item that can be used for messing up the outfielder's progress. Players that share good chemistry can also perform buddy jumps and buddy throws. Buddy jumps are used to take away a home run or a deep fly ball. Buddy throws are used to throw the ball faster and more accurate to its destination. Bad chemistry, however, results in slower throws, and sometimes throwing off track.

==Items==
===Error Items===
There are a total of seven items that are available during the course of ''Mario Super Sluggers'' gameplay. If the on-deck batter has Chemistry with the batter at the plate, a randomly-selected item can be used to inhibit fielders by aiming the Wii Remote immediately after hitting the ball. In [[Toy Field]], items work the same way but are chosen by a roulette wheel. These are as follows:
====Default items====
{{content description
|name1=[[Green Shell]]

|description3=When the POW-Ball hits the ground, any players (including the user's team) within a large radius are stunned by an earthquake for about four seconds. Characters who levitate or fly are not affected by the quake. This can also be avoided by timing a jump. If the POW-Ball directly hits an individual fielder, they are knocked away and the quake effect does not occur.

==Challenge mode==
[[File:Challenge-MSS.png|thumb|300px|The Challenge Mode menu.]]
Challenge Mode makes a return in ''Mario Super Sluggers'', returning as the Story Mode (and is the primary feature of this installment). The gameplay procedure for this mode includes a more in-depth story and an overall map screen involving the [[Baseball Kingdom]] locale. Along with recruiting players to go against Bowser's team, the players must solve from time to time certain puzzles and/or complete certain tasks in order to get to the main goals to proceed. Once Challenge Mode is cleared, Bowser becomes a playable captain character, and [[Bowser Pinball]] is unlocked.
===Captain abilities===
While navigating the [[Baseball Kingdom]], depending on progress made in the Challenge Mode itself, the five Team Captains listed below can use unique abilities to help them do numerous events, including recruiting other Team Captains/Team Players, finding coins, and gaining access to certain areas they could not reach before. The abilities in question are as follows:
*'''Mario:''' Talking to plant life, such as flowers and hedges, and being able to use [[Warp Pipe]]s.
*'''Peach:''' Being able to interact with things such as tree stumps, water, and etc. to make characters appear.
*'''Yoshi:''' Being able to use Manholes to reach other areas and [[Ground Pound]] the ground by trees to make characters come out.
*'''Donkey Kong:''' Being able to climb vines and smash wooden barrels and crates using his [[Hand Slap]].
*'''Wario:''' Being able to pick up metal things with his magnet and open [[treasure chest]]s.

==Cinematics==
[[File:Mss intro mario stadium entrance.png|thumb|Mario and friends rushing into Mario Stadium, with Wii Remotes in hand.]]
During the course of gameplay in ''Mario Super Sluggers'', players are able to encounter certain cinematic scenes that correspond with the game's Challenge Mode. There are a total of four cinematic scenes that can be seen by the player in this game, which also includes the game's opening (seen when the game starts up).

Although the basic criteria still remains for players to encounter them during gameplay itself first, they are able to view the four cinematic scenes outside of gameplay as well. These said cinematics can be accessed for viewing when the Challenge Mode category is added to the Records section (provided that the player has completed the Challenge Mode gameplay itself at least once). When viewing the Challenge Mode statistics in Records players can find the four videos in the Movie List sub-category.
===Opening===
[[File:Mss intro end of ballgame.png|thumb|left|All of the players gathering around Mario and Luigi after Lakitu calls the final "out", and the ball game]] Although this is seen for the opening of ''Mario Super Sluggers'' overall (after the game loads), it is still a combination of previewing the gameplay, as well as setting up what happens in the game's Challenge Mode. This is the very first video the player views.

The game's intro cinematic begins with [[Toad]], [[Princess Daisy|Daisy]], [[Mario]], [[Luigi]], [[Yoshi]], and [[Birdo]] riding a yacht en route to the [[Baseball Kingdom]], which is the location where ''Mario Super Sluggers'' takes place. The yacht arrives, and they meet up with [[Princess Peach|Peach]] and [[Toadsworth]], who greet them at the entrance. Peach escorts them to the lighthouse at the Daisy Cruiser, showing them an overview of the Baseball Kingdom. From there, they run into the [[Mario Stadium (baseball stadium)|Mario Stadium]], holding Wii Remotes. Closeups of Daisy, Luigi, and Mario follow in regards to swinging their Wii Remotes. Daisy is shown first encountering her Wii Remote, transforming it to her bat. Luigi encounters the same result as Daisy, and Mario's Wii Remote transforms into a baseball. Mario pitches the ball to Daisy right away following this, and she is seen hitting it. 

After Daisy countered Mario's pitched ball, the scenery immediately changes as the ball is chased after by Toad in the [[Peach Ice Garden]] until he runs into a large [[Freezie]] and turns frozen solid upon collision. He is later freed by a [[Toad (species)|Blue Toad]] who accidentally crashes into the Freezie (with Toad revealing that he made the catch after being defrosted). The ball then rolls onto [[Wario City]], where [[Wario]] chases after it to find it shoot into the air from a manhole water spout. The ball lands on Wario's head, causing him to fall backwards, and causing the ball to fly into [[Yoshi Park]]. Yoshi jumps over a [[Warp Pipe|pipe]] to catch the ball, realizing he is going to fall, he flutters around, but falls in with the ball; all while [[Birdo]] watches and does nothing. The ball flies to [[Diddy Kong]] at [[DK Jungle (baseball stadium)|DK Jungle]], he suddenly screams in terror as he is about to get run over by a giant barrel, when [[Donkey Kong]] rescues Diddy Kong by smashing it. Diddy sighs in relief.

The view switches back to Mario Stadium, where Mario pitches to Donkey Kong, who then makes a hit. Yoshi goes for the catch, but both Wario and [[Waluigi]] bombard him with [[Bob-omb]]s. Yoshi slides to the catch regardless, throws it to Peach, who throws it to Mario, and then to Luigi on base. Donkey Kong rushes to the same base where Luigi is standing resulting in Donkey Kong performing a body check on Luigi, sending him spiraling to the field wall. Daisy, Toad and the spectators panic upon Luigi's collision towards the field, but they find out seconds later that Luigi has caught the ball. [[Lakitu]] calls the final out, and everyone storms the field where Mario and Luigi are standing, congratulating them. After that, a final overhead shot of the Baseball Kingdom is seen to conclude the opening.

===Bowser Jr. and Crew Crash the Party===
[[File:Mss cm intro bowser jr gang.png|thumb|The unexpected guests]]
This is the cinematic that is shown as the player is just beginning the Challenge Mode for ''Mario Super Sluggers''. It takes place after Mario, Luigi, and Lakitu notice that there is something strange going on outside of the Baseball Kingdom.

[[File:Mss cm intro bowser jr.png|thumb|left|Bowser Jr. watching the Baseball Kingdom]]
This cinematic starts with an overhead view of the Baseball Kingdom itself, but this time, through [[Bowser Jr.]]'s surveillance view. Bowser Jr. pulls a lever, which results in his own venue, [[Bowser Jr. Playroom]], emerging from the sea. Then, with a large amount of force, he goes full speed ahead towards the Baseball Kingdom, resulting in his own stadium ramming headfirst onto the northern portion of the island. Mario and Luigi go on to investigate this suspicious matter as they witness the arrival of Bowser Jr. and his minions, which also includes [[Bowser]].

===The Hard-Earned Victory===
[[File:Mss main ending celebration.png|thumb|200px|Mario and the other characters after winning the final game against Bowser's team]]
If the player makes it to Bowser's Castle while it is sunset at dusk in the Baseball Kingdom and defeats Bowser's team, then this is the main ending that is seen.

Upon getting the final win, Mario and the other characters gather around the middle of the diamond to celebrate their victory. Bowser then slams his bat to the turf in a fit of rage.

Afterwards, the crew marches toward the entrance of the Baseball Kingdom to gaze towards the sunset. [[Princess Peach|Peach]]'s brooch begins glowing, which magically lights up the island for the night.

===The Final Festivities===
[[File:Mss yoshi peach daisy.png|thumb|200px|Yoshi, Peach, Daisy, Birdo and Toad all celebrate the fireworks display and homerun event at Mario Stadium]]
This is the fourth and final cinematic that the player can view in ''Mario Super Sluggers''. It is also triggered during the Challenge Mode after defeating Bowser's team a second time.

Mario and other characters are celebrating in the Baseball Kingdom during the night, and [[Princess Daisy|Daisy]] starts things off by marching with the others to the [[Daisy Cruiser]] to have some desserts, which represents a special thanks for saving her when Bowser Jr. previously transformed her into a statue. At one point, in stark contrast, Daisy unknowingly escorts Bowser and Bowser Jr. to the cruiser, much to everyone's disapproval. Various characters are seen at different tables manned by different types of desserts, while Bowser and Bowser Jr. stand by one table, still feeling depressed and distraught after losing a decisive showdown.

Moments later, a display of fireworks storm the night sky, much to the excitement of everyone viewing from the Daisy Cruiser. The characters are later seen at the Mario Stadium, where [[Mario]] and [[Donkey Kong]] assist in the fireworks display that represents a Bob-omb Derby show as well; the two counter Bob-ombs that were shot out from the cannon across from them, which explode into fireworks. The spectators and characters viewing from the bench are amazed at the fireworks.

[[Wario]] and [[Waluigi]] then walk up to the cannon and sabotage it by inserting a [[Bullet Bill]] into the cannon. The cannon prematurely fires with the Bullet Bill directing towards Mario. Bowser emerges out of nowhere and hits the Bullet Bill with his bat, making the Bullet Bill go in the other direction towards Wario and Waluigi. Wario and Waluigi then run away from the Bullet Bill. The Bullet Bill destroys the cannon in the process and grabs Wario and Waluigi, sending them blasting off at the speed of light. After flying upwards, a ginormous fireworks explosion from the Bullet Bill goes off. They begin to fall down from the explosion. As the crowd cheers, Bowser steadily walks away, and Donkey Kong watches off, feeling that Bowser and his son should not have been spared after all the mischief they committed at the Baseball Kingdom.

===Notes===
[[File:WaluigiGlitch-MSS.png|thumb|200px|The mirrored "Γ".]]
*In the second cinematic (''Bowser Jr. and Crew Crash the Party''), a Shy Guy, a Boo, and a Dry Bones accompany Bowser Jr. as he walks out of the Bowser Jr. Playroom. However, in the gameplay itself, Shy Guy is with the Yoshi Eggs team, while Boo is with the Wario Muscles team.
*In the third cinematic (''The Hard-Earned Victory''), Birdos of several colors run out and celebrate the victory against Bowser with the rest of the players. However, only the pink Birdo character is playable in the game itself. They also appear in the first and fourth cinematic scenes, however, here, they are not playable as alternate color palettes for Birdo.
*In the fourth cinematic (''The Final Festivities''), when [[Wario]] and [[Waluigi]] are falling after being taken by the [[Bullet Bill]] to the sky, the "Γ" in Waluigi's cap is horizontally reversed; the duo's positions are also reversed compared to previous shots, so the footage seems to have been inverted by mistake.

==Toy Field mode==
{{main|Toy Field}}
Toy field has returned from ''Mario Superstar Baseball''. Toy field has one Batter, and three other Outfielders and a cannon that pitches the ball to the batter. Before it pitches it, there is a roulette wheel with three different slots that affects the turn. Each slot is controlled by one of the outfielders; the outfielders tap 'A' to stop the slot they are in control of. If the slots aren't stopped, they are stopped automatically.

==Records==
[[File:MSS Records Map Screen.png|thumb|300px|The Records menu]]
While playing the game, various records are kept to see what achievements players have pulled off.
===Minigames===
Players can check the top 5 scores for each minigame, along with the top 5 for Toy Field and Minigame Madness (the latter being unlocked by completing all the minigames at all skill levels).

===Challenge===
Players can check their status in Challenge mode by seeing which characters they've recruited, the badges that they've earned, along with the four cutscenes and staff credits. The credits layout includes a few snapshots from the four cutscene videos, as well as snapshots from the gameplay itself.

===Team Captain/Team Player List===
Players can check the former MVPs, the star players, badges, and the Minigame Madness records for each character here.

===Badges===
Players are able to earn badges by completing certain tasks in the game, which are listed on the following chart:

===[[Mario Super Sluggers cards|Cards]]===
[[File:MSSC My Collection.jpg|thumb|200px|The first eighteen "Level 1" cards featuring all twelve Team Captains and six Team Players]]
[[Nintendo|Nintendo of America]] created an online {{wp|Adobe Flash}} program hosted at [http://www.mariosupersluggerscards.com MarioSuperSluggersCards.com] in which players can collect and trade virtual ''Mario Super Sluggers'' baseball cards featuring many of the characters, special moves, teams, and stadiums from the title. In addition to the cards, the game also allows players to earn downloads. By placing two compatible cards in the double play drop zone, players can make "double plays" and unlock special videos, wallpapers, and screensavers. When a player completes their collection, a post featuring Mario and all of the cards is unlocked. In addition, their username will be added to the leaderboard below players who previously completed their collections. 

After creating a username and choosing which ''Mario Super Sluggers'' character to use as an avatar, players are instructed to click on special banners found on child-friendly websites around the internet in order to collect cards. [[Lakitu]], who gives instructions and hints to the player, tells the player that the one banner can be found on [http://www.nick.com Nick.com]. Clicking on one such banner redirects the player to one of eighty-two Uniform Resource Locators (URLs), each of which corresponds to one of the eighty-two cards. The system is based on luck, but players are also able to trade cards with one another using the swap function or discuss where to find banners and which cards yield double plays.

By checking their history, players can manipulate the system into giving them whichever card they wish. By checking their history, players can find which URL leads to which card and then share the URL with other players.

The eighty-two cards are divided by rarity into four levels. Forty-one character cards make up the first level, twenty-four special swing/pitch cards make up the second level, twelve team cards make up the third level, and five stadium cards made up the fourth level. Each card has a front and a back. For the "Level 1" cards, the front shows the character's artwork, name, and for captains, the team they are captain of. The back shows the character's name, abilities, "rookie year" (the year their first video game appearance was released), description, statistics, and for captains, team logo. An in-game screenshot of the player is also featured.

==Reception==
===Critical reception===
''Mario Super Sluggers'' received generally positive reviews from critics. Cris Watters from Gamespot praised the game for how "The computer can provide a stiff challenge when set on a high difficulty level, and building your roster and lineup to capitalize on chemistry between your players is a fun exercise." and the fun multiplayer baseball gameplay although he criticized how the production values are not noticeably higher than in the original game, how the game was less challenging and complex than the original, and how there was not a good alternative to motion controls.<ref>{{cite|date=August 27, 2008|author=Watters, Chris|url=www.gamespot.com/reviews/mario-super-sluggers-review/1900-6196919|title=''Mario Super Sluggers'' Review|publisher=GameSpot|accessdate=June 29, 2024|language=en}}</ref> Anthony Dickons from Nintendo Life praised how well polished the game is and criticized how it is based off baseball which produces a limited gameplay experience.<ref>{{cite|url=www.nintendolife.com/reviews/wii/mario_super_sluggers|publisher=Nintendo Life|language=en|author=Dickens, Anthony|date=September 26, 2008|accessdate=June 29, 2024|title=''Mario Super Sluggers'' Review (Wii)}}</ref>

|7/10
|''Better than playing baseball, better than watching baseball, but it is still baseball. Fans of the sport or those who enjoyed previous Mario sports titles should find enough here for an entertaining time. Namco have included quite a lot of extras, no doubt to compensate for the slight lack of depth in gameplay which is of no fault of the game but more the sport it tries to represent. Mario Super Sluggers is a well produced game which squeezes everything it can out of the genre.''

|''Despite its many shortcomings, Mario Super Sluggers is good enough to offer some solid entertainment to the right gamers. Collect-'em-all Mariophiles will dig the new challenge mode, and Wii party hosts will enjoy playing frantic multiplayer games. More serious baseballers will find satisfaction in facing off against one another, but will find the rest of the package wanting. While there's certainly fun to be had, it's a shame Super Sluggers couldn't find that balance between accessibility and complexity that has made past Mario sports games so successful.''

==Glitches==
{{main|List of Mario Super Sluggers glitches}}
===Close play camera lock===
During close plays, if both the baseperson and the runner are rendered incapacitated during the special animation (i.e. [[Enlarge]]), the camera will remain fixated on the base until the next at-bat. This probably occurs because the game relies on the close play to finish uninterrupted to change the camera. This glitch can be achieved by pre-firing a [[POW Block|POW Ball]].<ref>{{cite|author=Mario Sluggers Fanclub|title=WE'VE NEVER SEEN THIS MONTY MOLE GLITCH #shorts|url=youtube.com/watch/KZJ4uEg8ni4|date=December 12, 2022|publisher=YouTube|language=en|accessdate=June 29, 2024}}</ref>

===DK's face appearing differently during replays===
When [[Donkey Kong]] uses the [[Barrel Swing]], he will show a neutral expression on his face, but if it is seen during a replay, he will show an angry expression instead.<ref>{{cite|author=Dingohazel|date=May 16, 2024|url=www.youtube.com/watch?v=dqT9XwpDoJs|title=(MSS) DK's face changes during replay|publisher=YouTube|accessdate=June 29, 2024}}</ref>
