This little beauty is a serpent of Native American Huron legend said to dwell in lakes and rivers, and when provoked it overwhelms its prey with disease and death. I ran with the disease idea and made my two active words 'putrid' and 'disgusting'. Putrefaction is the harbinger of disease, and maggots its heralds. I combined that with the overpowering nature of a boa-constrictor with the gnarly fangs of a viper to try and make something truly horrifying.
