Cannon

Cannons are objects that appear in various Kirby games, and make their debut in Kirby's Adventure. Kirby or another character can jump into a cannon to be shot out to another location.

The cannons on the ground are usually black and very large in size; they resemble big-bored medieval cannons. Many of these cannons have a fuse that Kirby needs to ignite using a Sizzle-elemental Copy Ability in order to use it. Upon doing so, Kirby must quickly race into the cannon before the spark touches it, as this activates the cannon. If the spark reaches the cannon before Kirby does, he has to reignite the fuse and reattempt at entering the cannon. The cannon spins around first before firing Kirby up into the air. Certain cannons remain upside down after spinning and then blast off into the air to take Kirby to the next destination. The cannon depicted in its Kirby Portal artwork is colored dark blue.

Kirby Super Star introduced the round-shaped cannons found in midair, but they are smaller than the cannons on the ground. They have a similar function to Barrel Cannons in the Donkey Kong Country series, especially Blast Barrels because most of these cannons fire Kirby automatically. The midair cannons are usually white in color with red arrow placed on a light green pattern. The arrow indicates the direction where the cannon fires. Some midair cannons spin before firing Kirby whereas some instantly fire him out when he enters one.

Game appearances
In Kirby: Triple Deluxe, some of the midair cannons turn or slide horizontally whenever the Nintendo 3DS system is tilted. There is also a keychain of Kirby inside of a cannon, depicting the Kirby's Adventure sprite.

Some midair cannons appear in the The Great Cave Offensive stage in Super Smash Bros. for Wii U and later Super Smash Bros. Ultimate. They are based on the cannons in Kirby Super Star, like the overall stage itself. If a fighter jumps into a midair cannon, it rotates in eight directions before firing them out. Like other cannons in the Super Smash Bros. series, being fired from a cannon deals damage to other fighters.

In Kirby and the Rainbow Curse, there is a figurine of a cannon.

"Light the fuse of a cannon with fire or another ability, then climb inside and get ready to blast off. (page 22)

Kirby and the Rainbow Curse figurine
"Don't worry about Kirby when he's shot out of a cannon. He has to do it in order to break blocks or hit a wall, and he's perfectly fine afterward. But for the rest of you, no crawling into cannons, OK"
