Ochre Jelly

Ochre Jelly is a harmless ooze and a key ingredient of Ochre Jelly Ale. When used in the brewing process, it causes spills to crawl back into the into the container that it was spilled from. This helps to keep bars clean making Ochre Jelly Ale popular amongs tavern owners.
Famously, The Great Ochre Jelly Regurgitation of '35 was an incident where a bad batch of Ochre Jelly Ale crawled from the stomachs of bar patrons all over Mithlerien and back into their tankards. Sadly, the ale does not taste good if regurgitated and reimbibed!
