Kannon

Kannons are large cannon-wielding members of the Kremling Krew; they only appear in the games Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2.

Donkey Kong Country 2: Diddy's Kong Quest / Donkey Kong Land 2
In Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, Kannons are common enemies, and attack by shooting barrels or kannonballs at the Kongs in whatever direction they're facing, either forward or downward. Kannons can be found in several levels, but mostly underground areas. Despite being large and burly, Diddy Kong and Dixie Kong can easily defeat a Kannon with any attack method.

According to the instruction booklet, Kannons are simply Klumps trained to use such weapons. However, while normal Klumps wear army gear (green helmet, grenade belt, etc.) Kannons wear more of a pirate ensemble, such as earrings, a large belt, and a large black hat with a skull and cross-bones on it. Also, Kannons seem to have distinct ears.

According to the game's credits, Kannons belong to the "Kremling Kuthroats" enemy class.

Trivia

 * Kaptain Skurvy, a character from the Donkey Kong Country animated series resembles a Kannon. The only obvious difference is that Skurvy has a hand-cannon instead of a cannon, but it's still large enough to fire small cannonballs.
 * Kannon was named "Klumpa" in earlier builds of Donkey Kong Country 2.
 * In the GBA version of Donkey Kong Country 2, Kannon's defeat sound uses the same voice clip as Krunch from Diddy Kong Racing.
