The squonk (Lacrimacorpus dissolvens) haunts the hemlock forests of Pennsylvania, chiefly at night. It is sad and tearful most of the time because it is so damn ugly, covered with warts and moles. I have no idea if the squonk is a literary creation or a piece of Pennsylvania folklore. To see a drawing, surf to: http://www.hum.au.dk/romansk/borges/vakalo/zf/html/the_squonk.html
