The Agguggt! are a species native to either the Alpha, Beta, or Gamma Quadrant. They appear to be writhing greenish bubbles inside a translucent sack. They were present for the trade conference on Deep Space 9 in 2370. After the bombing of Garak's shop, the Agguggt! ambassador told Sisko that it had been punctured by a shard of metal, though Sisko couldn't discern any damage. The Agguggt! then left Deep Space Nine promising there would be restitution. (DS9 novel: Betrayal)
