A Gummy Slug can be combined with a sweetener to cook a Gummy Cake in the Crock Pot. The Gummy Cake will also reduce the Sanity of the player but will restore much more Hunger (the same amount as a Meaty Stew).
Webber and Wilba can eat Gummy Slugs without the Sanity Penalty. Wilba will turn into a Werepig after eating two gummy slugs.
As Stone Slabs do not regenerate their items, Gummy Slugs are non-renewable, luckily however, their spoilage time is much longer compared to other food items, making it feasible to save this food to make Gummy Cake.
The Cooked Gummy Slug is a Food item made by cooking a Gummy Slug on a Campfire, Fire Pit, or other viable source of fire. As Gummy Slugs are non-renewable, damage sanity by 5, restore an inferior amount of hunger and spoil faster when cooked, eating a Gummy Slug like this is not recommended.
