Kracka

Krackas are Knockas wearing TNT Barrels on their head.

Summary
Kracka are an unused enemy in the original Donkey Kong Country 3, and were brought into the game's Game Boy Advance remake. The Kracka is presumably identical to the ordinary Knocka, but explodes on contact and turns into a TNT Barrel when jumped on. The Kracka, is likely based on the Kaboom from Donkey Kong Country 2. The Kracka runs at the player when he sees the player. If he makes contact, he will explode, hurting one of the Kongs. However, if he is jumped on, he will curl up into a regular TNT barrel.
