The Ghost Weed is a flora species found in deep biomes. The ghost weed is most commonly found in the Lost River but can be found in Blood Kelp Zone and Bulb Zone too. It can be harvested for Ghost Weed Seeds with a knife.


The Ghost Weed boasts a peculiar appearance. It has a green and red bulbous base, followed by two long green stems, each with several small protrusions near the tip and three short red stems, giving off a dull bioluminescent glow.

  • The Ghost Weed was originally called the Red Green Tentacles.
  • Ghost Weeds once lacked the brine damage immunity afforded to the majority of life forms inhabiting the Lost River. Due to this, Ghost Weeds that were in contact with brine took damage upon loading in and would die, causing them to vanish. This oversight was most visible in the Ghost Forest.
