Barnacle

Barnacles are stationary animals found in the Commonwealth and on the Island

Background
Barnacles are usually much larger than the smaller crustaceans that can often be found beside them. They can be encountered in coastal regions of the Commonwealth and the Island. They can be easy to miss due to their dark shell coloration, making them resemble rocks and harder to spot when traversing coastal terrain. Before the war, toxicity levels had been steadily rising in barnacle specimens, reported by the Nahant Oceanological Society as more than 34% above those in control tanks.

Characteristics
Upon approaching it, the barnacle releases a radioactive cloud that irradiates the player character at a rate of +30 rads/s for a few seconds.

Appearances
Barnacles appear in Fallout 4 and its add-on Far Harbor.

Behind the scenes
The barnacle was designed by Gabrielle Adams and created in ZBrush.
