Gello Grotto

From publisher blub:

The job takes a strange job from the Baker's Guild. Apparently, a Gelatinous Cube in the sewer was recently slain. The 'monster' was responsible for cleaning the sewer area and keeping the smell down. The party must head north along the coastline and find a cave where the creature was originally captured and bring another back in its place!

Although set in the Margou Campaign, this adventure setting is easily adaptable to most any game and system. This scenario was created for five, third level adventurers.
