Bile demon

Bile Demons are obese creatures without legs. From their heads protrude two horizontal horns. Attached to the end of each horn is a morning star. They move by lifting themselves up with their long arms and moving the body ahead, setting down and repeating that manoeuvre.

Bile demons are ugly, gluttonous minions that relish in sewage and fecal matter. Mercury has made it a mandatory rule that any bile demons under her command must be scrubbed clean. This has made her a terror to the demons, and is a task that her goblins take to with a sadistic glee.
