Mincers are spike-ball objects that are exclusive to Donkey Kong Country and Donkey Kong Land. They spin rapidly and are usually moving and/or floating. It is interesting to note they function somewhat like Zingers, but are much more threatening due to the fact that they're completely invincible; not even a TNT Barrel can damage it.
They are not found in most stages, appearing in a few later stages, though when they are, Mincers are usually the main enemy or the main feature in the stage. In Donkey Kong Country, they appear in "Torchlight Trouble", "Poison Pond" and "Manic Mincers". They also appear in the stage "Spiky Tire Trail" in Donkey Kong Land.
