Not to be confused with Mecha-Zinger
Bionic Bees are an enemy in Donkey Kong Country Returns 3D, and only appear in the Cliff temple, Perilous Passage. There are only four seen in the level. They are gray and have blue eyes and rapidly fluttering wings. Their bodies are covered in electricity. They will fly straight towards you and go around platforms to get to you. Once they are underneath the conveying platforms, they will bonk their heads and fly away. Later in the level, two more will appear, possibly the same pair. It is rather strange that they only appear in an old, crumbling temple overrun with lava and not even once in the Factory world. It is also unknown how they got inside the temple.
