Kaboom

Kabooms are red Kremlings and the TNT Barrel-wearing variant of Klobbers. They first appeared in Donkey Kong Country 2: Diddy's Kong Quest. Kabooms disguise themselves as ordinary TNT Barrels and pop out when a character gets close. They do not appear in Donkey Kong Land 2.

Krackas were originally planned to be the successors to Kabooms in Donkey Kong Country 3: Dixie Kong's Double Trouble! but were later removed, making the rope-climbing Klasps their only successor. However, in the Game Boy Advance port, they appeared in a Pacifica level, Stormy Seas.

Donkey Kong Country 2: Diddy's Kong Quest
Kabooms are common enemies the later worlds of Donkey Kong Country 2. They first appear in the Gloomy Gulch level, Ghostly Grove, and are mainly found in the Lost World and K. Rool's Keep. Their behavior is shared with Klobbers: they both hide in their barrel, then pop out when Diddy and Dixie get close, and run after them, attempting to collide into them. Kabooms' TNT Barrels are distinguishable from normal ones, because the "N" of TNT is flipped. This is fixed after Diddy or Dixie jumps on it.

The only major change between Klobbers and Kabooms is that the latter's barrel explodes when it crashes into the lead Kong. Both of them are defeated from the TNT blast. Diddy and Dixie have a few other ways to defeat Kabooms without injury. One method is by throwing a projectile, such as a barrel or a kannonball, at Kaboom. The Kongs can also jump on the Kaboom and throw it like a regular TNT Barrel. As with Klobbers, the Kongs can grab the barrel that Kaboom hides in before it emerges, but only if quickly done so. Kabooms also get defeated if they run onto the spikes in Klobber Karnage, but they do not explode.

Kabooms are one of the few entities absent from the end credits. However, in the Game Boy Advance version of the game, one shares a listing with a Klobber.

Donkey Kong 64
Kabooms, called TNT Bombers or "TNT Barrels" in the Prima guide, return as enemies in Donkey Kong 64, where they have a larger appearance and no longer wear earrings.

TNT Bombers are first shown during Diddy's segment of the DK Rap, where Diddy simultaneously defeats three of them by throwing an orange at them. During the game itself, TNT Bombers first appear in the later segment of Diddy's Mine Cart Ride, where they jump out of edges at random as an attempt to crash into him. If a TNT Bomber successfully hits into Diddy, he loses a few DK Coins.

TNT Bombers only appear in the Angry Aztec and Gloomy Galleon worlds themselves. They have a similar attack pattern as in Donkey Kong Country 2. While they are chasing the active Kong, TNT Bombers sometimes say "C'mon" in a high-pitched voice. TNT Bombers are more easily identifiable from their outer TNT Barrel. Like many other enemies, the active Kong can defeat a TNT Bomber by throwing an orange at them, using a musical instrument, or by shooting with their weapon. The active Kong can also use a shockwave attack but at a cost of being injured from the explosion. TNT Bombers automatically self-destruct after chasing after the active Kong for five seconds, and say "Uh oh" right before exploding. The only remains of a TNT Bomber after exploding is a pile of ash with two blinking eyes on top.
