Kannonball

Kannonballs are large, black steel balls that have appeared as items throughout the Donkey Kong series of games. Kannonballs first appear in Donkey Kong Country 2: Diddy's Kong Quest throughout the game's many levels. A Kannonball can be grabbed by Diddy Kong or Dixie Kong and used as a weapon against enemies, even though the main purpose of Kannonballs is to bring them to a Kannon. Once a Kannonball is thrown into a Kannon, it will activate it and allow Diddy Kong and Dixie Kong to be blasted to a Bonus Barrel.

Kannonballs are also hazards that the Kongs have to avoid. They're often fired by Kannon, and unlike Barrels, can't be jumped on. Kannonballs are also shot out of Kaptain K. Rool's blunderbuss, which can be thrown back into it when he uses it as a vacuum to cause a backfire. In addition, he can also fire a spiked Kannonball.

Kannonballs also appear in Donkey Kong Land 2, where they serve the same basic purpose as in Donkey Kong Country 2: Diddy's Kong Quest, being used as a weapon and the key to activating Kannons.

In Donkey Kong 64, a single, extremely large Kannonball can be found near the entrance to Gloomy Galleon. Players must have Chunky Kong lift this Kannonball and bring it to a nearby Kannon; once the Kannonball is brought to this Kannon, it will activate it. Using the Kannon, players must use it to shoot several moving targets in the room they're in, with a limited amount of time and Kannonballs for ammunition. If players hit all the targets with Kannonballs, they will gain a Golden Banana.

Trivia

 * Unlike the Kannonballs of Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, the Kannonballs in Donkey Kong 64 explode when they hit something, instead of simply bouncing off them.
