The Hungry Hungry Homus
A giant face is carved into a rock on Labion, and is known as the Hungry Hungry Homus. It is said that the mouth of the Hungry Hungry Homus will eat forever. A fabled strongman was once able to hold his jaws shut for a time, and allow his friend passage into the dungeon. His friend was never heard from again.
Roger Wilco was also able to hold his jaws shut with glue for a time, and therefore able to traverse into the dungeon below.
