Brainy Matter is a Food Item exclusive to the Shipwrecked DLC. It is acquired by picking the Brainy Sprout and cannot be cooked or used in a Crock Pot. When consumed, it will restore 50 and 10 , and damage the player by 10 . It spoils very quickly and will turn to Rot in 1 Day's time. Once picked, the Brainy Sprout will take 20 days to regenerate.
Brainy Matter can be used to create the Brain of Thought, which can be used as a portable crafting station to access recipes which have not yet been prototyped by one of the stationary crafting stations.
- Due to its fast spoilage, Brainy Matter will lose its 50 sanity consumption bonus at half a day's time after it is picked; thus, it is best to consume it immediately when looking for sanity gain.
- Corals are animals. Specifically, they are marine invertebrates living in colonies. Therefore, Wigfrid is able to eat Brainy Matter.
- If one is planning to turn the Brainy Matter into a Brain of Thought, one should plan ahead and get the necessary Jellyfish and Rope to make it once the matter is picked, as there will only be 1 day before it spoils.
