Robokremling

Krobots, also called Robo Kritters, are mechnical Kremlings that appear in Donkey Kong 64. They are most likely created by King K. Rool and they can only be found in Frantic Factory.

Summary
Krobots are commonly seen walking around patrolling a certain area. Krobots are very durable enemies as regular attacks cannot defeat them. The only ways to defeat a Krobot is to either throw orages at it, use the Blast move, or to play a musical instrument. After a Krobot has been defeated, it will give up two melon slices.

Trivia

 * Krobots are one of two enemies in the game to give up two melon slices when they are defeated. The other are Koshas.
 * Sometimes, a Krobot may stop and rewind itself before walking around again. This is a perfect chance to either throw an orange at it or run past it.
 * Krobots are the most common enemies in Frantic Factory.
