Splatoon is a third-person shooter video game franchise developed and published by Nintendo. It is set far in the future on a post-apocalyptic Earth that has been repopulated with evolved marine life and centers around a pair of humanoid races derived from cephalopods known as Inklings and Octolings—squids and octopuses respectively—which can morph between humanoid and cephalopodic forms at will. They often battle one another in competitive sport, using a multitude of weapons that produce and shoot ink while in their humanoid forms or swim through and hide in solid surfaces covered in their own ink while in their cephalopodic forms.
