Writhing Weed is a flora species found mainly in shallower biomes.

It is mostly found in the Grassy Plateaus and Safe Shallows. It has no use in the game and is purely [[::Category:Cosmetic|cosmetic]]. The player can cut it with a knife to obtain Writhing Weed Seeds.


The Writhing Weed seems to be a cluster of small, purple, neon green tipped tentacles, capable of emitting bright bioluminescent glows.

Well-adapted to both shallow waters and cave systems, this plant lives in symbiosis with a coral species which forms around the base of the stems.



  • The Writhing Weed was originally called the Purple Tentacle.
  • The coral species located under the plant look similar to those found underneath on the Slanted Shell Plate.
