Glommer's Goop is a Food Item dropped by Glommer periodically every 2-4 Days, or during their death. Other than its use as fuel for a Fire (with a fuel value equivalent to Boards), it can be eaten, providing 40 Health and around 9 Hunger, but decreasing Sanity by 50. It can also be used as a Fertilizer for Farming, with as much strength as Manure.
- The sanity penalty is helpful in some scenarios, such as trying to farm Nightmare Fuel from Shadow Creatures, trying to lower an Insanity Obelisk, or going to the Lunar Island.
- When eaten by Walter, he will start singing a song.
