Cannon

"Hey! Mario!!! Great timing! I could use a hand here! I'm kind of...stuck."

- Bowser

Cannons are used to fire all kinds of projectiles in the Super Mario franchise, including other characters. They have a more generic appearance and use than Bill Blasters, which specifically shoot out Bullet Bills. Cannons are usually part of the environment and cannot be destroyed.

Super Mario Bros. 3
Cannons make their first appearance in Super Mario Bros. 3, where they show up in the airship, tank, and boat levels. They are found on floors and ceilings and continue firing when touched, and come in several configurations. While some are turrets that fire straight ahead like Turtle Cannons, common fixed cannons shoot their cannonballs diagonally. Some of these grounded cannons are mortars that eject Bob-ombs at short distances. There are four-barreled quartet-cannons (or cannon quartets), which fire in two directions at a time, then rotate at a 45° angle. There are also double-barreled diagonal cannons that are mounted on background elements such as semisolid metal bays, and can fire out of either end. Lastly, there are horizontal giant cannons, which fire giant cannonballs.

Super Mario World
While no normal cannons appear in Super Mario World, a pipe variety called Pipe Cannons make an appearance. They are slanted pipes that shoot Mario or Luigi diagonally as part of a screen transition.

Super Mario 64 / Super Mario 64 DS


Cannons, this time colored blue, are a vital gameplay element in Super Mario 64 and Super Mario 64 DS. There is at least one cannon found in ten levels in these games, as well as one secret stage. Each of the cannons that can be found throughout the games is under the control of Bob-omb Buddies. The player must successfully locate and talk to the Bob-omb Buddies in each level in order to access the cannon or cannons for that particular level. Until they do, the cannons remain covered by a metal hatch with a picture of a Bob-omb Buddy on it, and are inaccessible. The location of each Bob-omb Buddy becomes increasingly difficult to find as Mario progresses through the game.

When a cannon has been unlocked, the metal hatch slides away, revealing a square hole in the ground. In order to use the cannon, Mario needs to only drop down into this hole. The cannon then rises out of the hole, and the player can use it to fire Mario to previously unreachable areas. When Mario has entered a cannon, a targeting reticle appears on the screen, allowing the player to aim the cannon where they want Mario to go. Once the cannon is locked on target, the player must press the button to fire (or  in the remake). The player should aim slightly higher than the area they wish to shoot Mario to, as the height of Mario's trajectory tends to gradually decrease after he is fired from the cannon. Mario will not take falling damage if he is fired from a cannon. If the player collects a Wing Cap before entering a cannon, the player can fly around as Wing Mario immediately after being fired from the cannon, without needing to perform a Triple Jump to take off first. Cannons cannot be unlocked until after the first mission is completed.

In Bob-omb Battlefield, there is a cannon controlled by a Bob-omb that Mario can never access due to the cannon shooting water bombs.

There is also a cannon outside the Mushroom Castle, though it is covered by a small metal grate as opposed to a metal hatch. The cannon can be unlocked and used only after Mario has collected all 120 Power Stars in the game. When the cannon is used, the player is able to access the roof of the Mushroom Castle, where Yoshi and a hidden Wing Cap await. For the DS version, if 150 Power Stars are collected, Luigi can capture the green minigame rabbit from the roof. In the Whomp's Fortress mission "Blast Away the Wall," Mario must shoot himself out of a cannon in order to obliterate the topmost section of a nearby wall, which releases the hidden Power Star.

Super Mario Sunshine
In Super Mario Sunshine, there are very few Cannons, most of which are operated by Monty Moles. These cannons are completely red in color and have three openings from which multiple Bullet Bills, Purple Bullet Bills, and Golden Bullet Bills can be shot. They effectively take the place of Bill Blasters in this regard. When Mario approaches the cannons, the Monty Moles cease firing Bullet Bills at him, and instead begin pelting Mario with multiple Bob-ombs, which Mario must diffuse (by spraying them) and then throw back at the mole to defeat it.

The first cannon that is encountered in this game is found on the upper west side of Delfino Plaza. When Mario first comes across it, a Pianta mechanic working inside it tells Mario that it is unfortunately out of order, and therefore unable to be used at the moment. However, after Shadow Mario has kidnapped Princess Peach and taken her to Pinna Island, the cannon becomes accessible, and Mario is able to use it to shoot himself to Pinna Island to pursue Shadow Mario. From this point on, the cannon continues to act as Mario's only means of transport to Pinna Park, which he must return to every time he wishes to travel there. When Mario enters this cannon, he is automatically shot to the island, without needing to aim first.

The second cannon in the game can be found near the entrance to Pinna Park, and is manned by a Monty Mole. In the episode "The Beach Cannon's Secret", Mario must dodge incoming Bullet Bills and make his way to the cannon, where he must throw Bob-ombs at the Monty Mole to defeat it. After it has been defeated, Mario must enter the cannon's opening to complete a Secret Level and return to Delfino Plaza. Mario can also use the Bullet Bills fired from the cannon as an opportunity to collect many Blue Coins, which are hidden under baskets that can only be broken open by Bullet Bills.

The third and final cannon in the game is found in Episode 1 of Noki Bay. In this episode, the cannon is positioned atop an extremely large cork, and continuously shoots out Glorpedoes which gradually fall down cliff faces and cause widespread pollution in the area. Mario must make his way to the top area of Noki Bay until he reaches the area with the cannon. Again, he must defuse Bob-ombs and then throw them back at the Monty Mole to defeat it. This time, the entire cannon explodes when defeated, and the cork blocking the waterfall is dislodged, releasing the Shine Sprite for that episode.

New Super Mario Bros.
A type of cannon called a Warp Cannon appears in New Super Mario Bros. These cannons blast Mario or Luigi to a different world. They are usually unlocked by finding a red-flag exit in a level. Upright Pipe Cannons also appear, and this time blast Mario or Luigi straight upwards when entered.

Super Mario Galaxy
Cannons reappear in Super Mario Galaxy. These cannons appear to be more advanced than the cannons from Super Mario 64 and they largely fulfill the same role as in that game. They also have much more precise aiming, since the player uses the to aim. The button fires the cannon and Mario or Luigi can get to high places and Power Stars. He is not shot in an arc, however. He keeps going in a straight line and can lose a life if shot out of the gameplay area, as he does not fall down unless he hits a surface.

In the Super Mario 3D All-Stars version of Super Mario Galaxy, the player can no longer pan the camera while in cannons by holding down and moving the controller away from the screen, due to the lack of a Sensor Bar.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, upward and downward-pointed cannons and mortars from Super Mario Bros. 3 that fire cannonballs and Bob-ombs reappear, in addition to the rotating quartet-cannons and horizontal giant cannons. The normal cannons in also routinely rotate their barrel to the other direction before firing again. One quartet-cannon is a large rotating cannon pipe that fires giant cannonballs out of three cannons, with one cannon actually being a pipe that does not fire and which characters must enter. Warp Cannons and Pipe Cannons from New Super Mario Bros. also appear.

Super Mario Galaxy 2
Cannons once again appear in Super Mario Galaxy 2. However, they only appear in Bowser Jr.'s Boom Bunker, where they are mostly used in place of Launch Stars. In the Throwback Galaxy, the cannon from Whomp's Fortress is replaced by a Sling Star. Cannons in these games are mostly the same as the original, but there is a target to land on. If the hero manages to hit the center, he gets an extra life.

Super Mario 3D Land
Cannons appear in Super Mario 3D Land in several levels, with a similar function to Super Mario 64 and Super Mario Galaxy. However, it can now controlled by moving the Nintendo 3DS around, just like the binoculars. Cannons are also provided by Toad for either Mario or Luigi, and are often found in the level after his Toad House stage. These cannons are used by the heroes to gain access to the airship levels where either Boom Boom or Pom Pom appear to challenge them.

The cannons in this game share the same color scheme of that with a black body and blue outlines.

New Super Mario Bros. 2
Warp Cannons return in New Super Mario Bros. 2, though they act much different than before. In addition to a dark blue color scheme instead of a black color scheme, they gain access to 'Dash Mario' stages, which have Mario or Luigi continuously running through a short Subspace-esque setting dodging enemies and timing jumps to get through the level, with optional coins to collect which also act as a guide to getting through the level. Collecting a row of coins causes a audience to clap. Completing these stages allows Mario to gain access to other worlds.

Pipe Cannons also return from the previous games, acting much in the same way. These pipes first appear in World 1-A. Mortars that fire Bob-ombs also reappear, though they launch them as Parabombs in this game.

New Super Mario Bros. U
In New Super Mario Bros. U, boss cannons take an important role in castles. After Mario, Luigi, Yellow Toad, and Blue Toad finish the castle, they run up a flight of stairs and jump inside the cannon and blast into one of the Koopalings' airships and start the Koopaling battle. Pipe Cannons also appear in levels and in the world map, the latter of which is used to travel to other worlds. The normal cannons and giant cannons from Super Mario Bros. 3 also appear and act in the same way; they appear in The Mighty Cannonship from Soda Jungle as well as in some challenges of Challenge Mode.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
Cannons also appear in Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury in the Tank levels during cutscenes. They are used at the beginning of the levels near Sprixies to transport the player to the stage. They also appear as enemies. They most prominently appear in World Star-9 (Cosmic Cannon Cluster), and attack like in previous games. If a Brick Block is destroyed under a cannon, it changes into a Cannon Box, which can be used to attack enemies and destroy cracked walls.

Super Mario Maker / Super Mario Maker for Nintendo 3DS
Cannons reappear in Super Mario Maker and Super Mario Maker for Nintendo 3DS in all styles. They fire cannonballs once more, and can be set in one of eight directions. The game introduces a red variation that fires red cannonballs which travel faster. Adding a Super Mushroom makes it larger in size and shoot giant cannonballs. Unlike Bill Blasters, items and enemies cannot be placed inside a cannon; therefore, it can only shoot cannonballs. They can be defeated by big Stilettos.

In all styles except the New Super Mario Bros. U style, while the editor icons depict a unique sprite of a cannon aimed diagonally, the level sprite for such a cannon is actually the horizontal or vertical cannon sprite rotated 45 degrees, as shown in the image on the right.

The American English description from the Nintendo 3DS eShop erroneously says that cannons can shoot coins.

Super Mario Run
In Super Mario Run, cannons are timed to fire cannonballs at specific moments during their on-screen duration. This careful timing can be used to gain height from the air when playing Airship levels (2-4, 4-4, 6-3). They spawn in single sets, but also double and triples, giving players more space to bounce off of when facing a barrage of cannonballs.

Super Mario Maker 2
Cannons and their red variations return in Super Mario Maker 2, where they behave as they did in the game's predecessor, appearing in all styles except the Super Mario 3D World style.

In the version 3.0.0 update for Super Mario Maker 2, the Cannon Box appears as a power-up.

Donkey Kong (Game Boy)
In Donkey Kong for the Game Boy, cannons appear in a variety of forms. In the Desert, the cannons have a dated look taken from the Middle Ages (the image on the left); on the Airplane, cannons are made out of steel and look more contemporary (middle image). Both types of cannons retain the same basic function and fire out bullets that look like Bullet Biffs, acting similar to the seed-spitting Dōryī except they sometimes fire two shots at a time. In later Airplane levels, different cannons charge up energy balls and routinely change their angle of fire, shooting diagonally and upwards as well (the image on the right). If Mario gets hit by any of their projectiles, he loses a life.
