A Bursting Blekko was strange suicidal life-form native to the swamp world of Thram. Vaguely resembling a theropod dinosaur, Bursting Blekkos would charge at intruders while inflating a red protrusion on their back. When in range, the creature's red protrusion would then explode, causing massive harm to the intruder. If their primary attack did not kill the intruder and the Blekko, they continued to jump and chomp at him until he kills them. They typically attacked in pairs, and often hung around swarms of Serathoids.
