Penguin Bomber
From Sonic Retro
Penguin Bombers are a variety of badnik created by Dr. Ivo "Eggman" Robotnik, encountered by Sonic or Tails in Robotnik Winter Zone during Sonic Triple Trouble. These robotic suicide bombers waddle around the frigid slopes of their zone, forming explosive slalom obstacles for a snowboarding Sonic. When the hedgehog isn't riding a snowboard, the penguins can be dispatched with a standard spin attack.
In Act 3, the source of these badniks is found to be the boss of Robotnik Winter, Giga Thomas "Pen".
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.
