Octoplush is a band in Splatoon 3. Their music is played in Return of the Mammalians in most missions in Alterna, and can also be heard by using the jukebox. The genre of most of their music is electronic, although their songs are quite varied within that genre. Their album art depicts many FuzzyOctotroopers standing in lines and has a border with text, bearing a resemblance to the album art of Turquoise October, another band whose music plays in single-player modes.
Octo refers to "octopus", while plush may be a reference to the softness of the Fuzzy Octarians. Additionally, the name "Octoplush" is similar to "OCTOTOOL", the Japanese name of Turquoise October.
