During gameplay in the many levels of Donkey Kong Country 2 and Donkey Kong Land 2, either Diddy or Dixie can pick Kannonballs up and use them to attack even the strongest types of enemies, including the common foes, Zingers. However, the main use of Kannonballs is to access hidden Bonus Areas. To find these special stages, the two monkeys must carry a Kannonball across the stage to a cannon. If they throw the ball into a Kannon and walk into it, they will be blasted upwards into a Bonus Level. Sometimes, though rarely, Kannonballs can be hidden in Treasure Chests, which must be broken to open.
