Buggernaut
From Sonic Retro
Buggernaut, or Bun-būn (ブンブーン) in Japan, is a blue mosquito badnik from Sonic the Hedgehog 3 found in Hydrocity Zone. In behaviour, they are very similar to the Whisp. They attack in groups of 2 (the adult mosquito and the young mosquito). When the adult badnik is destroyed, the smaller one flies away in panic. They can be easily destroyed by jumping. "Bun-bun" is a Japanese word for buzz.
It's name is a pun on the word "Juggernaut".
