As its name suggests, the Brain Squid resembles a squid and has a large, yellow brain on its head. It emits a constant purplish light and stays afloat while moving in a pattern.
If Fox or Krystal approach a Brain Squid, it spins its tentacles and slowly moves toward them. Brain Squids can be defeated by throwing a Fuel Barrel or Basket at them. Fox has two additional methods for defeating a Brain Squid: by striking it once with the Staff or a single use of Fire Blaster. Most Brain Squids respawn after a while, except for ones that must be defeated to open a Life-Force Door.
