Garglesnap. A reclusive dragon found only out where the sea is deep. This ferocious creature is swift in water, and capable of inhabiting above-sea, commonly inhabiting caverns dug from underwater cliff faces which open into wide cavernous rooms and the sky beyond. From birth all Garglesnap are capable of spitting a viscous, toxic and potent acid which can burn a man into a puddle in moments. Extremely dangerous, kill on sight.
