The quernug is a strange creature that resembles a sheep. They stand about 2ft tall and are covered in purple, matted wool, have a frog-like mouth, and have two horns on the sides of their head. Quernugs make a strange barking sound and will hop around, blindly following humans and other creatures. They are generally harmless, but may sometimes bite their companions, resulting in serious wounds, infection, and prolonged illness. Quernugs reproduce by spitting up eggs in a nest of mud and rotting leaves.
