Birklas Plunth was a rat-hunter who partnered with Blather Roe in Lamentable Moll. He wore rags and a large, floppy, magenta-colored, leather hat. His belt, wrists, and ankles were decorated with braids of rat tails. He and his partner enjoyed picnicking atop the city's large Knoll Barrow, eating roasted rats and their pickled babies. The pair's knowledge of the city and its underworld made them invaluable to watch sergeant Guld.
