Megg is a depressed, drug-addicted witch. Mogg is her black cat. Their friend, Owl, is an anthropomorphised owl. They hang out a lot with Werewolf Jones. These characters struggle unsuccessfully to come to grips with their depression, drug use, sexuality, poverty, lack of work, lack of ambition and their complex feelings about each other in ways that have made Megg and Mogg sensations on Hanselmann''s Girl-Mountain Tumblr.
