In celebration of Guillermo del Toro's new opus The Shape of Water, Mr Jim Moon sets sail on a new new podcast series and submerges the Great Library of Dreams Bathysphere into the deeps to discover all manner of aquatic horrors. In this first episode, we explore the Gill-man's ancestry in mythology, legend and folklore, encountering kappas, nixes, nymphs, tritons and of course various mermaids and merfolk.
