Octo Valley (location)



Octo Valley is the setting of the story mode in Splatoon. It is the home base of the Octarians. It is comprised of many large domes, their interior walls covered with screens that display images of the surface.

Trivia

 * The official Japanese Splatoon Twitter account stated that Octo Valley "was made using the remains of an ancient civilization. It seems to be using very familiar things... or is it just my imagination?" This seems to hint that Splatoons events take place on Earth, long after humans have gone extinct.
