The Bonnacon is an Asian beast whose head is like a bull but his horns curl inwards so that they do not harm the victim.
Because these horns are useless for defense, the Bonnacon has another weapon. When the Bonnacon is chased he expels dung which burns a wide area.
...As the creature retreats it emits a trail of dung that would sometimes cover a distance as long as three furlongs, or approximately 3 acres.
Any contact with the creatures dung would scorch the pursuer like a sort of fire.
This napalm like excrement may have given rise to legends that the Bonacon also had the ability to breathe fire, much like the European Dragon, making this creature deadly at both ends...
