Knocka

Knockas are green lanky Kremlings who hide in green barrels with faces painted on them. Their name is derived from the word "knock", which applies with their behavior. They are encountered in both Donkey Kong Country 3: Dixie Kong's Double Trouble! and Donkey Kong Land III. They are the direct successor of Klobbers from Donkey Kong Country 2: Diddy's Kong Quest and Donkey Kong Land 2, though unlike Klobbers, the barrel worn by Knockas can easily be differentiated from a regular barrel. In the Gameboy Advanced version, they borrow sounds used by Klobbers from the prequel.

Knockas have two variants, Klasps and Kuchukas. The former climbs across a horizontal rope while hiding inside a TNT Barrel and the latter stays inside a purple barrel and throws bombs at Dixie Kong and Kiddy Kong. In the Game Boy Advance version, they have another variant, Kracka, a ground variant of Klasp, appears in a Pacifica level.

Donkey Kong Country 3: Dixie Kong's Double Trouble!
In Donkey Kong Country 3: Dixie Kong's Double Trouble!, Knockas are common enemies who appear in many levels. Like their predecessor, Klobber, a Knocka hides in its barrel; if Dixie Kong or Kiddy Kong approaches the enemy, it attempts to knock into them. They cannot directly injure the Kongs, so Knockas try and hit them into another enemy or a pit. To defeat a Knocka, the Kongs must jump onto it, pick it up, and throw it. Unlike Klobbers from Donkey Kong Country 2: Diddy's Kong Quest, Dixie and Kiddy do not lose any items if a Knocka hits them.

In Dixie Kong's Photo Album, a Knocka is categorized under the Kremling Kreeps.

Donkey Kong Land III
In Donkey Kong Land III, Knockas, along with Klasps and Kuchukas, are still semi-common enemies. They retain their behavior from Donkey Kong Country 3: Dixie Kong's Double Trouble! The ending of the game erroneously titles Knockas as Krushas.

When Knocka is carried by a Kong in the Game Boy Color version, it changes from green to red, because it uses the same exact sprite and palette as a regular carried barrel. When the Kong puts the Knocka back onto the ground, it changes back to its normal green color.
