Medieval Monsters: The Bonnacon (MM4)

The bonnacon is  a bull like creature, but with curling horns like a ram. While it is said that these horns are useless, clearly they can be used as ram's horns are, and the creature has hooves as well. Its hide is tough, but it fiercest weapon is its extremely dangerous flatulence, an extremely high pressure emission of flaming dung and gas, some of which was said to travel more than two acres. The creature is not usually aggressive, but may become territorial or irritable during mating season or in the defense of offspring.
