Zingers are spiked wasps and one of Donkey Kong's foes, next to the Kremlings.
They first appeared in Donkey Kong Country and Donkey Kong Country 2, where they guarded the skies. They cannot be stomped, and must be defeated with a projectile or certain Animal Buddy. Red Zingers are invulnerable to everything except the explosion of a TNT Barrel.
In Donkey Kong Country 3, Zingers were replaced by mechanical bees called Buzzes. Green Buzzes can be defeated with a barrel or Animal Buddy, while red Buzzes can only be destroyed with a TNT Barrel. They played the same role.
Zingers appeared in MKFusion where they still played the same role from Donkey Kong Country. You can spin jump on them, but it has no effect. Zingers appeared in a few levels such as Bramble Scramble. At the end of the level, there is a large Zinger boss called King Zing. They are defeatable by anything except stomping. Either they're allied with King K. Rool or Legion.
