BuckBot

Buckbots are robotic chickens that appear in Donkey Kong Country Returns and Donkey Kong Country Returns 3D. They only appeared in the Factory area of Donkey Kong Island. Buckbots basically move around from one direction to the next, attempting to run into Donkey Kong and Diddy Kong. Fortunately, they can be destroyed by any attack method.

Buckbots and Buckbombs were most likely created by Colonel Pluck, considering that the Buckbots do appear during the boss fight.
