Barrel Cannon

A Barrel Cannon, also spelled Barrel Kannon and also known as a Cannon barrel, is an object prominently featured in most of the Donkey Kong titles. Once entered, the barrel shoots the character in the direction indicated by its arrow. They are most often used for crossing large abysses.

Donkey Kong Country series
Barrel Cannons have appeared in every Donkey Kong Country and Donkey Kong Land game to date. In these games, if a Kong goes into the barrel, it will either stay still, move horizontally or vertically, or spin around (also referred to as Spin Barrels ). The player can usually blast out the Kongs by pressing the jump button. Barrel Cannons often appear in groups, which often includes their auto-fire variant, the Blast Barrel; an example of this is in the Donkey Kong Country level Barrel Cannon Canyon, where Barrel Cannons are prominently featured for crossing wide pitfalls throughout.

Blasting from a Barrel Cannon often requires timing, as the player must take various things into account, including obstacles, enemies, or sometimes even other moving Barrel Cannons. This is to avoid crashing into an enemy or obstacle or falling down a long pit.

They come in many varieties in the Donkey Kong Country games, especially in the first three games. These include Arrow Barrels, Blast Barrels, Tracker Barrels, Rotatable Barrels, Steerable Barrels, and Booster Barrels. In Donkey Kong Country Returns, Donkey Kong Country Returns 3D, Donkey Kong Country: Tropical Freeze, and its Nintendo Switch port, Barrel Cannons only come in four varieties: Barrel Cannons, Blast Barrels, and skull versions of both, which destroy themselves when they fire the Kongs. In Tropical Freeze, Barrel Cannons gain a more rugged appearance, having chipped or faded paint in many places.

Other Donkey Kong installments
In Donkey Kong 64, Barrel Cannons take the appearance of red Blast Barrels, though most are not automatic. They are only used by Donkey Kong in the Baboon Blast courses, as well as during the final battle with King Krusha K. Rool.

Barrel Cannons can be encountered in New Play Control! Donkey Kong Jungle Beat, replacing the cannon flowers from the original GameCube game. They are completely stationary in this game, and once entered, they will only shoot Donkey Kong in one direction. In order to blast DK out of a Barrel Cannon, the player has to swing the Wii Remote.

They also appear in the game Donkey Kong Barrel Blast, along with new varieties in red and gold. In DK: King of Swing, they appear where the player has to jump into a cannon, as it turns left to right, and press the or  button to blast into the air.

Super Smash Bros. series
In Super Smash Bros. and Super Smash Bros. Melee, a Barrel Cannon appears in the Kongo Jungle stages, where it moves back and forth and occasionally rotates underneath the stage. If a character falls into the cannon, they can press the A button to fire themselves out of the cannon in the direction of the arrow. If they wait too long, they will be shot out anyway. Since the cannon sometimes rotates, this action can sometimes save players from falling, or it can launch them to their doom. Only one character may occupy the Barrel Cannon at any time. The Melee version can also be used by Klaptraps that fall into it; they inflict damage if the cannon is touched while they are inside it, or if they are fired towards the stage.

In Melee, it is also a usable item. Aside from always rotating and destroying itself upon firing, it works just like the stage variation. This item is quite heavy, thus only Donkey Kong can move around freely while holding it. When thrown, the barrel rolls until it touches a character or falls off the arena. If anyone else touches the barrel while it is occupied, they will take moderate damage. Also, Barrel Cannons disappear much faster than any other item if left alone.

Viewing the Barrel Cannon trophy from the bottom reveals the message "2L84ME" ("too late for me"), also seen on a crate in official artwork of Cranky's Cabin.

From Super Smash Bros. Brawl onward, Barrel Cannons do not function as a regular item. However, they appear in the Subspace Emissary in that game and Smash Run in Super Smash Bros. for Nintendo 3DS, and have a new smooth, black appearance and a yellow arrow with a red outline. Characters use these to get shot up higher or break Brick Blocks in their way. Barrel Cannons also reappear in Super Smash Bros. for Wii U, both in the returning original Kongo Jungle stage and in the new stage, Jungle Hijinxs. The Kongo Jungle stages also reappear in Super Smash Bros. Ultimate, though the Melee version is renamed Kongo Falls.

Mario Kart series
Throughout the Mario Kart series, some cannons take the form of barrels. In DK Mountain, a course in Mario Kart: Double Dash!! and Mario Kart Wii, there is a giant Barrel Cannon (referred to in the former as Donkey Cannon and in the latter as DK Cannon) that blasts competitors to the top of the mountain. A Barrel Cannon with the same function appears in the DK Summit course of Mario Kart Wii as well as in Maple Treeway from both Mario Kart Wii and Mario Kart 7, but it does not include the DK initials in the latter course. Another Barrel Cannon is featured in the Mario Kart 8 and Mario Kart 8 Deluxe overhaul of N64 Yoshi Valley, replacing the Long Route. A silver Barrel Cannon with blue hoops and supports appears on the planet section of 3DS Rainbow Road R in Mario Kart Tour, where it launches drivers off to a different portion of the track. A Blast Barrel can also be seen on the Barrel Hanafuda glider.

Mario Tennis series
In Mario Power Tennis and Mario Tennis: Power Tour, Donkey Kong mounts and shoots from a Barrel Cannon as part of his Offensive Power Shot, the Barrel Cannon Blast.

In Mario Tennis Aces, several Barrel Cannons appear when Donkey Kong's Special Shot animation is triggered, enabling him to perform the shot by launching him from one to another.

Mario Party series
Barrel Cannons appear in DK's Jungle Ruins board of Mario Party 9. If the player lands on a Lucky Space, they will be launched to a floating island to increase their Bananas counter. Many Barrel Cannons appear in the boss minigames Diddy's Banana Blast and DK's Banana Bonus, where the players use them to reach Bananas.

Only a single giant Barrel Cannon appears in Mario Party 10, located at the top of the Donkey Kong Board. Whenever the player's amiibo comes across this cannon, they will be offered the possibility to enter the cannon and get launched to one of the spaces the other players are on.

Barrel Cannons return in Mario Party: Star Rush, in the minigame Leafboard Hoard. The objective is for players to select a Barrel Cannon, and competing for one with the most coins, and then launch from that one.

Mario Baseball series
Barrel Cannons make a minor appearance in Mario Super Sluggers in adventure mode. When the player travels to DK Jungle, Donkey Kong meets him and says that there is a waterfall too far for him to jump across. Nearby, in a bush, is a barrel cannon that will launch the player across this waterfall.

Mario & Luigi: Bowser's Inside Story / Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
In Mario & Luigi: Bowser's Inside Story and Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, Mario and Luigi obtain a Special Attack called Yoo Who Cannon where the bros. jump into Barrel Cannons and are shot at enemies. This same attack was planned for the sequel but was removed.

Mini Mario & Friends: amiibo Challenge
Barrel Cannons appear in Mini Mario & Friends: amiibo Challenge as the gimmick of Barrel Blast Jungle. There are stationary Barrel Cannons, which spin around continuously, as well as Barrel Cannons that do not rotate but move from one side to the other on a line. Barrel Cannons display a light-emitting disc, which turns red when Mini Donkey Kong is inside the cannon. If the disc is tapped with GamePad while Mini Donkey Kong is inside, he gets launched from the barrel. Alongside Barrel Cannons, there are also Blast Barrels.

WarioWare Gold
In the Donkey Kong Country microgame from WarioWare Gold, the player has to fire Donkey Kong from a Barrel Cannon onto a row of bananas. The Barrel Cannon takes the form of a Blast Barrel, although it only fires the character at the player's command. In the first two difficulties, the Barrel Cannon moves up and down, while in the third difficulty, it rotates 90 degrees in one place.
