Kaboom

Kabooms are red members of the Kremling Krew. They wear a TNT Barrel around their body. They also slightly resemble Krackas, an enemy from Donkey Kong Country 3: Dixie Kong's Double Trouble!.

Donkey Kong Country 2: Diddy's Kong Quest
Kabooms first appear in Donkey Kong Country 2: Diddy's Kong Quest as common enemies. Kabooms are relatives to Klobbers. Like Klobbers, Kabooms wear barrels around their body, but Kabooms wear TNT Barrels. This makes them extremely dangerous, as a simple touch will cause them and a Kong to explode. Kabooms can be defeated by throwing a barrel or a kannonball at them. Kabooms can also be thrown and used like a normal TNT Barrel. The Kongs must jump on its head in order to use them as a TNT Barrel. Kabooms are predominantly found in the Lost World and K. Rool's Keep.

Donkey Kong 64
Kabooms make a return appearance in Donkey Kong 64. In this game, they are rarer than before, found only in Angry Aztec and Gloomy Galleon. Their attack method is the same as before though - they charge at one of the game's five playable Kongs, attempting to damage them with an explosion. Kabooms can be defeated by throwing an Orange at them, or by firing fruit from the Kongs' shooters. A shockwave attack also takes them out, but it hurts the Kongs in the process. Kabooms also appear in Diddy Kong's minecart challenge in the area Jungle Japes. In this area, they will jump of edges and explode, trying to take Diddy out with them. On a side note, when a Kaboom chases a Kong in this game, they'll automatically self-destruct after about 5 seconds.

Three Kabooms also show up in Diddy's segment of the DK Rap; they end up being blown up by Diddy with an Orange.

Trivia

 * Whenever a Kaboom starts to run or makes a quick turn, it makes a noise similar to tires screeching.
 * Occasionally, in Donkey Kong 64, Kabooms can be heard saying "C'mon" in a high-pitched voice. Also, whenever a Kaboom is defeated, all that remains of them is a pile of ash with two blinking eyes on top.
 * In Donkey Kong Country 2, a Kaboom can defeat itself by coming into contact with any kind of terrain that can hurt the Kongs.
