Fog crawler

Fog crawlers are creatures, which appear in the Far Harbor add-on.

Biology
Fog crawlers are mirelurk-like creatures, which live on Far Harbor. Physiologically they appear to be mutated descendants of a species of mantis shrimp. These creatures are remarkably tough, withstanding multiple Gauss rifle hits with very little loss of health.

Appearances
Fog crawlers appear only in Fallout 4 add-on, Far Harbor.
