|A preserving fluid for edible souls. Apparently they're a delicacy.|
Jars of ethereal fluid are an item that was involved in the 2015 Hallowe'en event, during which the player must evict the Anti-Santa for the Grim Reaper. It was found in the kitchen and searching the refrigerator. They must be used to catch Souls in the graveyard, to obtain a trapped soul.
