Krobot

Krobots , also known as Mecha-Kritters, are mechanical Kremlings from Donkey Kong 64 on the Nintendo 64 console.

Description
Their roles in the game are similar to the regular Kremlings in any Donkey Kong games, being the obstacles that like to get in the way of the players. They appear only in the Frantic Factory level where they are seen wondering around. They can only be defeated either by tossing an Orange Grenade at them, playing a musical instrument near them, or by one swing of Chunky Kong's Primate Punch.

Krobots are among the few Kremling enemies in the game, the others being the Klumps, the Koshas, and the Klobbers in which like the other three, they cannot be defeated by simply attacking them with normal B button assaults, nor can they be destroyed using any of the Kongs' firearms. However, unlike the other three Kremlings, the Krobots do not necessarily require any items as Chunky can still destroy them with his signature slam.
