Bomblur

Bomblur (ボンブラー) is a variety of Badnik created by Dr. Eggman, encountered by Sonic or Tails in Atomic Destroyer Zone during Sonic Triple Trouble. There are only a handful in the entire game, found bouncing back and forth between horizontal banks of springs. True to their name, Bomblurs ricochet very quickly, and can easily smack the rings out of Sonic when they bash into him. They can be dispatched with a standard spin attack. Like other robots in 8-bit Sonic games, no animal friends pop out of Bomblurs when they are destroyed. Whether these badniks canonically don't contain organic batteries, or the escaping critters simply weren't shown due to programming limitations, is not known.
