Gut Buster is an enemy Badnik encountered in Chaotix.
Sporting a white chef's hat, this Badnik can be found in Techno Tower, where it wanders back and forth around the highs of its skyscraper home, looking scarcely less threatening than a walking trashcan. However, this robot does have one trick up its sleeve - periodically the machine will stop and cough a bomb vertically up into the air, catching and swallowing it again when it comes back down. As such, it is dangerous only if the player has the spectacular ill judgement to Spin Jump into it just as it's preparing to hurl. It is better to wait until it swallows the bomb, or Spin Dash into it.
