Millstone Gnawties are large versions of the common enemy Gnawty from Donkey Kong Country. Gnawties will run on Millstones, as if they were hamsters, on temple stages to chase the Kongs once Donkey or Diddy Kong come in its way. Millstone Gnawties will remain dormant until a Kong gets in front of it. The Millstone Gnawty will then start moving along a straight, set path, directly in the monkey's way. Unlike their weaker walking versions, these Millstone Gnawties are completely invincible, and even possess the ability to float above normal ground.
