Blue Barnacles are a flora species that will be present in the expansion in the Twisty Bridges biome.
Blue Barnacles superficially resemble cluster of coral, embedded in a calcified, dark gray base. They have a maw with a light turquoise bioluminescent glow.
Blue Barnacles visually look a very similar to real life barnacles, however they instead are a species of flora, instead of being a type of fauna.
