Brain Coral

The Brain Coral is a type of coral. It produces bubbles that refill 10 units of Oxygen.

It is found in many biomes, namely Safe Shallows and their caves. The fact that they spawn in caves is very helpful and in some cases life-saving, because they spawn about three Oxygen bubbles at a time, filling up the player's Oxygen level by 30.

Brain Coral spawn bubbles day and night. They do not react to being attacked, and never move. They are completely ignored by other life forms.
