The Mollog's Mob are an Underworlds warband whose members are the denizens of a dark, damp cave, a Bat Squig, a Stalasquig, a Spiteshroom and Jabbertoads, led by the Dankhold Troggoth Mollog the Mighty.
These creatures inhabited a mushroom-littered cavern under the dunes of the Desert of Bones for centuries, its Troggoth master only coming out of it to feed. Then a group of Skaven invaded from deep underground, so they were attacked and eaten, but in the fight the cavern was destroyed. Mollog and the denizens of the left to find a new one, only to stumble into the ruins of Shadespire. They went underground to find a damp place to rest and instead found themselves in the Mirrored City. Now they still search for a new quiet home to sleep in, smashing any who would cross their path.
