Fuzzy Octarians appear much like their non-fuzzy selves, except the sclera of their eyes resemble fuzzy ooze and the colored sides of their bodies are covered in a brown, carpet-like texture.
Fuzzyness is a physical condition in the Splatoon series, it was introduced in the single player campaign of Splatoon 3.
The condition are afflicted upon Inklings, Octolings and Octarians when they come into contact with Fuzzy Ooze, a marble-patterned pink, blue and yellow substance which makes them transform into strange mammalian/cephalopod hybrids.
