Bunyips are quite moody creatures often lashing out towards they're breeding partners with no real patterns to tell as why. Bunyips graze on the near by vegetation, until it's prey get to close it will then lash out at the prey, sometimes males will actively hunt prey as it wanders through it's territory.

Muggle sightings of bunyips vary regularly, often one description will sound entirely different to another and only some them sound anything like an actual bunyip. The creature known as the bunyip is a large marsupial that resembles a large dog with long canines, their fur can range in colour from browns to greys and they have yellow eyes. Male bunyips are the larger of the two but other than that show no other signs of difference between genders.
