Fourth wall

Sometimes, characters from the Mario and Donkey Kong series will state something that implies that they are aware of being fictional characters in a video game; this is known as breaking the fourth wall. The reason it is called a "fourth wall" is that the term originated from plays in theaters, when actors would look at the audience, talk to them, or do anything else that involved the audience. Because the stage would generally have a wall at the back and both sides, this concept involves the actors becoming involved with the audience who are at the front, which can be considered an invisible wall, making it the fourth one. The Fourth Wall is most frequently broken in the Paper Mario series.

''Note: Video games frequently break the fourth wall in order to address the player with directions (i.e., "Press A to jump"). These instances are not to be recorded here, unless a character is aware of the fact that they are in a video game due to the remark.''

Super Mario Bros: The Lost Levels
In the final level of World 9, a group of tile blocks can be found spelling out "アリガトウ!" (Arigato!, meaning "Thank You" in Japanese). Also, the Game Over screen for World 9 has a message saying "YOU'RE A SUPER PLAYER! WE HOPE WE'LL SEE YOU AGAIN. MARIO & STAFF."

''Super Mario World
After the Yoshi Eggs hatch during the ending sequence, the words "THANK YOU" appear as Mario gives the peace sign to the player while Princess Toadstool waves to him or her. At the end of the remake, Super Mario World: Super Mario Advance 2, there is no text, though the princess still waves at the player and Mario and Luigi will still flash the peace sign. In the last level of the Special World, Funky, a group coins spell out the phrase, "YOU ARE A SUPER PLAYER!" near the end of the level.

Super Mario 64 / ''DS
At the game's title's screen, Mario will speak to the player with lines such as "It's-a-me, Mario! Hello!" and "Press Start to play!". At the ending sequence, Mario (or Yoshi in the remake) points his face to the player.

In the two versions, after Bowser is defeated in Bowser in the Sky, he will exclaim, "C'mon, troops! Let's watch the ending together! Gwa ha ha!" Additionally, if Mario retrieves all 120 Power Stars and then defeats Bowser, the Koopa King will say, "Just you wait until next time. Until then, keep that Control Stick smokin'! Bwaa ha ha!" In the case of Super Mario 64 DS, Bowser says the same thing after all 150 stars are collected, however he mentions the Touch Screen instead of the Control Stick, as the DS does not have one.

After the end credits in both versions, Mario is heard saying, "Thank you so much for-a playing my game!" He uses the same phrase in Super Mario Galaxy and its successor, Super Mario Galaxy 2.

In the N64 version, after Mario collects all 120 stars, shoots to the top of the castle and talks to Yoshi, he gives Mario the following message: "Thanks for playing Super Mario 64! This is the end of the game, but not the end of the fun. We want you to keep on playing, so we have a little something for you. We hope you like it! Enjoy! --The Super Mario 64 Team"

In the case of Super Mario 64 DS, upon closing the Nintendo DS while playing, Mario says "Buh-bye!" to the player, after which the system goes into standby. When the system is opened, he says "It's-a-me, Mario!"

''Super Mario Sunshine
After Mario defeats Bowser and Bowser Jr., a certain yellow Pianta in Delfino Plaza will ponder whether the game is over and express his hopes of something else happening when Mario talks to him.

''New Super Mario Bros.
After the end credits, the Touch Screen shows Bowser Jr. dragging his unconscious father back to their home. Bowser Jr. looks to the camera and threateningly roars at the player. He then continues dragging Bowser. Similar to Super Mario 64 DS, Mario will also say "Buh-bye!" to the player when closing the Nintendo DS. He also says "It's-a me! Mario!" when the player opens the DS and resumes the game, similar to the opening title screen in Super Mario 64 and similar to that in its remake. The enemies also do a small jump when there is a little "Bop bop" vocal in the music.

''New Super Mario Bros. Wii
Most enemies, such as Koopas and Goombas, and Yoshis, will dance to the "Bop-bop" vocal that most levels' music scores have. The dancing characters face the screen, and the walking Koopas move their fists up and down as well. Also, if Bowser's Airship takes off without Bowser Jr. aboard, he'll face the player with a surprised sight.

''Super Mario Galaxy
Much like the ending to Super Mario 64, after the credits roll, Mario or Luigi will say "Thank you so much for playing my game" (Luigi, however, removes the "so much" part of the sentence). When 120 Power Stars are collected, after Mario or Luigi thanked the player, Rosalina will also thank the player and say she will "watch you from beyond the stars".

''Super Mario Galaxy 2
If the player's Wii Remote batteries are low, and he or she talks to Lubba, he will complain to them about the batteries running out in a dangerous place. Also, Lubba will frequently make these kind of references, such as suggesting that the player goes to bed when it's late, or to turn off the game after a certain playing time.

If the player has 70 to 120 Power Stars, then at the end of the credits, Mario says "Thank you so much for playing my game", much like in the previous version and in Super Mario 64(and in the DS remake). When playing as Luigi, he will also say the same thing.

If the player gets a Game Over or goes to a world for the first time, Lubba will speak to the player.

Super Mario 3D Land
In Special 8 Crown, a group of Snake Panels near the end can be activated to spell out the phrase "THANK YOU!!" similar to other thanking messages in Super Mario Bros: The Lost Levels and Super Mario World.

Donkey Kong series
Throughout these many games, Cranky Kong constantly makes remarks about how the games of yesteryear are superior to modern games, and often whines about how the game that he's in is too easy for someone like him to complete. More of Cranky's Fourth Wall-breaking comments can be found in the instruction booklets for these games.

''Donkey Kong Country 3: Dixie Kong's Double Trouble!
If the Kongs manage to find Krematoa on their own, Blunder will ask if they used the Player's Guide to find it, and confesses that he did so himself.

''Hotel Mario

Throughout the many other cut scenes of the game, Mario and Luigi will continue to speak with the player. These lines include Luigi saying "Looks can be deceiving when Koopas are involved." whilst facing the screen, and Mario saying "Remind me to check.", "You know what they say, all toasters toast toast." and "When you pinch Wendy's pennies, they pinch back." whilst facing the screen.

Also, at the end of the game, the Mario Bros. and Princess Toadstool wave to the player and congratulate him/her for the completion of the game, and Peach even thanks the player individually for helping her.

''Super Mario World 2: Yoshi's Island
In a secret area in Jungle Rhythm..., there is a Hint Block that gives the message "We, the developers, have poured our hearts into this game. We hope you enjoy finding all of its secrets.". In the Game Boy Advance remake, the message is changed to "'How do you like this game? Goodies are hidden in every level, you know. You should look all over if you want to get 100 points! Investigate anything that looks suspicious.".

''Yoshi's Story
Nintendo also broke the Fourth Wall in Yoshi's Story. Each time the player eats a Heart Fruit after playing a level's mini-game, a row of Coins forming a letter will appear. If the player puts all the letters from each level in order, it reveals the message "YOU ARE YOSHIS GREAT PARTNER!"

''Super Mario RPG: Legend of the Seven Stars
After Mario and Mallow join Geno while he's fighting Bowyer, Bowyer will retort that a three-on-one fight isn't fair. To compensate for this, the Y, X and A buttons of the SNES controller will appear in front of him. Bowyer will then fire an Aero at one of the buttons, which will effectively lock the ability to use that button's commands (magic, items or attacks). Only one button can ever be locked at once, although Bowyer will continually fire Aeroes at the buttons every few turns until he is defeated.

During the ending sequence, there is a scene where Mario, Princess Toadstool, Yoshi, Toad and the Chancellor wave at the player, with the words "THANK YOU" displayed at the top of the screen. The scene ends with the camera zooming in on Mario, who then winks at the player.

''Mario Golf (Nintendo 64)

Mario Kart 7
After the credits, Mario shouts "Thanks for playing! Way to go!" or "Thanks for playing! You're the best! Ha ha!" depending on how much the player has progressed, and the default characters or all of the characters wave to the player, including his or her own Mii.

''Paper Mario
If Goombario uses Tattle on a Goomba, the tattle mentions that they have been around since Super Mario Bros.

While Mario is fighting Bowser???, the Koopa Bros. try to lower his confidence by telling him that the phony Bowser is invincible. One of the things they say is "The sequel should be called Paper Bowser!"

When Mario wins a battle, he'll look at the player and give him/her a thumbs up. This also happens in the sequel.

When Goombella tattles on Stewart in Glitzville, she will tell Mario that Cheep Cheeps have been a part of the Mario franchise for a while. In fact, Goombella even says, "Oh, gosh. I just broke through the fourth wall there, didn't I? Sorry. Just forget it."

The same occurs when she tattles on the gatekeeper of Twilight Town, in which she says that the game would be too easy without him. Rather than directly referring to breaking the fourth wall, she only says, "Hee hee... Let's never speak of it again."

Koops breaks the fourth wall after the fight with Doopliss where he says "Sort of easy for a boss battle as it were." Unlike Goombella though, he doesn't seem to notice that he broke the fourth wall. Doopliss also breaks the fourth wall during the chapter by removing the lowercase p from the naming screen.

Just before Mario begins Chapter 5, Professor Frankly is about to tell them very important and long information concerning the Thousand-Year Door. He asks if they're ready to hear it, and then says, "And you there! In front of the TV! You listen up, too!". Mario's current partner out will question Professor Frankly (for example, Yoshi says to him, "Did someone pile-drive your head, or what? I don't see any TV here, nutjob!". Vivian remarks, "What to say... ARE YOU TALKING TO NO ONE?!?" Goombella even says, "Yeesh. First me, then you! Why do we always have to break through the fourth wall?") Frankly yells at them, saying to disregard it as he continues. Later during the chapter, Lord Crump (under his alias, "Four Eyes") tells the player that they'd better not tell Mario who he really is, though it is impossible to even use Mario to attack him until the end of the chapter.

After Chapter 6, when Bowser makes it to Rawk Hawk's secret training facility, Rawk Hawk appears. As soon as he appears, he points at the camera insultingly asking the player if they forgot him.

A Toad in Petalburg consistently breaks the fourth wall throughout the game. He states that he is a fan of Luigi and says he wants a game called "Paper Luigi". Later, he mentions that he is actually playing the game Paper Mario: The Thousand-Year Door and ends up beating it before the player does. In every chapter, he always talks about a different Nintendo game.

In early dialog stored in the game it says "Awww, game over, man! WHOOOOOOOOOOOAAAAAAA!", it has 7 versions of this speech, making it seem like a partner says it. This version is most likely said by Yoshi.

''Super Paper Mario
Several characters, the first one being Bestovius, refer to a certain button when explaining how to perform an action. When Mario asks what they mean by pressing that certain button, the character assures them not to worry, and that the great being that watches them (the player) will know what it means. For example, when encountered, Thoreau says: "What's this, you say? You need not worry. The great being that watches us will know what it is."

Bowser shouts to Mario, "No more sequels!" and that he will finish him off, describing himself as "100% Grade-A Final Boss." Later, during Chapter 3, the last option for Princess Peach to choose on the Swoon.exe will result in her to outburst in anger and demand to know who is picking these answers for her.

''Mario & Luigi: Partners in Time
Professor E. Gadd has a DS Time Radar to find the adult Peach, who is lost in time. He claims that Princess Peach is lost in the previous year. A Toad, however, doesn't believe him and thinks he made it all up.

Also, Luigi occasionally hums and whistles the Luigi Mansion theme, apparently aware of his own theme. Whenever he gets a key/valuable item, he shows it to the player.

''Super Princess Peach
Nintendo breaks the Fourth Wall during the beginning and end of the game. During the intro sequence, Bowser will tell the player to shut the door, using the Nintendo DS stylus, so that he and his minions could continue discussing their plan. During the ending sequence, the player is asked, "So, how did YOU feel about this last adventure?" The player is also told that the Vibe Scepter might be in their house somewhere.

''Mario Strikers Charged Football
Sometimes, the team captains will look at the screen, making it seem that they're looking at the player. One example is during one of Waluigi's losing animations where he looks at the screen and then prepares to punch it. Also, during Wario's home entrance, he will hum to his own theme.

''Super Smash Bros. Brawl
When Mr. Resetti is released from an Assist Trophy, he may tell the players to stop resetting, as he considers it to be a form of cheating in the Animal Crossing games. Additionally, if the game is being played late at night, he may tell the player to "get some shut-eye".

When using Solid Snake's codec on Sonic the Hedgehog on Shadow Moses Island, Otacon says that people are excited that he is in Super Smash Bros. Brawl. In the codec on Mario, Colonel says that Mario made his first appearance in 1981, and in Jigglypuff's codec, he says that it takes all kinds of energy in Super Smash Bros. Brawl; Colonel also mentions the WarioWare games in Wario's codec. Another broken wall is when using Solid Snake's codec on Pit, Colonel says that Pit has gone through "countless trials over the years", to which Snake replies, "And by 'trials', you mean 'Game Overs'?" Finally, when Snake uses his codec on Mr. Game & Watch, Otacon will talk about his first appearance, 1980, and his console, Game & Watch. There were other Codec Conversations that break the fourth wall as well.

There is a scene in the Subspace Emissary mode where Snake reveals himself after being hidden in his cardboard box for a long time. While facing towards the screen, he says "Kept you waiting, huh?" There are no other characters in his vicinity during the scene, so he must have been talking to the player - in reference to the fact that a brief scene of him hidden in the cardboard box was shown much earlier in the Subspace Emissary storyline.

In a similar manner, before facing Wolf O'Donnell in the Subspace Emissary, Wolf will appear to look at the screen, and strikes a pose at the challenger. Since Wolf doesn't interact with anyone directly, this is likely a sign of breaking the fourth wall.

Television Series
Before many of the games listed above came out, the Fourth Wall was broken in several of the cartoon episodes.

Throughout the three DiC cartoons, commercial bumpers for the shows were announced to the audience by various characters at the start and end of the commercial breaks (i.e. "Be right back, paisanos!", "And now back to The Super Mario Bros. Super Show!"). These commercial bumpers can be viewed on the DVD sets of The Super Mario Bros. Super Show!, but were not included on The Adventures of Super Mario Bros. 3 DVD set. Additionally, the first three weeks of episodes for The Super Mario Bros. Super Show all contained unique bumpers featuring scenes and voice overs related to the episode's live-action segment. All of the later episodes used a few generic bumpers that were announced by Mario, and showcased a still shot from the opening sequence.

When The Adventures of Super Mario Bros. 3 aired on NBC during its original run, a character from each of the two upcoming episodes, as well as a character from Captain N: The Game Master, which aired between the two episodes, would all narrate a preview of the upcoming episodes before the show started. This trend continued with Super Mario World. These previews were not included on the DVDs due to the fact that they are considered the property of NBC.

''The Super Mario Bros. Super Show!
At the start of the opening sequence, Mario shouts out to the audience "Hey, paisanos! It's The Super Mario Bros. Super Show!".
