Blue Barnacles are a flora species that grow in abundance in the Twisty Bridges biome.


Blue Barnacles superficially resemble cluster of barnacles, embedded in a calcified, dark gray base. They have a maw with a light turquoise bioluminescent glow.


Blue Barnacles visually look very similar to real life barnacles, however they are a species of flora, rather than being a type of fauna.
