Turquoise October

Turquoise October is a band or artist in the Splatoon series. They made the majority of the songs that play in Octo Valley and Octo Canyon.

Description
Not much is known about them, other than that their producer is DJ Octavio and that they make music to regulate and inspire the Octarians, with even one Inkling, Tsukeru Okimoto, waking up at 7 AM in the morning after listening to their music. Following Enter the Octobot King!, their music became more influenced by Inkling music, specifically pop.

As suggested by their album art in Splatoon 3, Mr. Grizz appears to have kidnapped and fuzzified them.

Trivia

 * Turquoise October's first album's art is unusual in that the text on it resembles their name in English localizations (looking like "TURQUIOZ OCTOBER" ), rather than the original Japanese name. The second album, however, stylizes the band name like the Japanese name.
 * They are the first band in to have their name changed for localization, preceding the Chirpy Chips.
 * The cover of their first album is a reference to The Man-Machine, an electronic music album composed by German band Kraftwerk.
 * Their album art in Splatoon 2 bears a strong resemblance to the X∞Multiplies album cover from the real-world band Yellow Magic Orchestra.
 * Turquoise October's name may be a reference to Tom Clancy's The Hunt for Red October, a novel involving naval officers and a submarine, reminiscent of the Great Turf War.
 * It may also be a reference to the American alternative rock band Blue October, simply changing the type of blue. One of Blue October's most successful songs was titled Into the Ocean, which fits with the oceanic theme of Splatoon as a whole.
 * It may also be named because October includes Octo.
 * Several Turquoise October songs in Splatoon 2 feature Callie's vocals from various Squid Sisters' songs, albeit reversed. This is likely to foreshadow the fact that she was under the Octarian's influence during the events of Splatoon 2's story, presumably when Turquoise October wrote the songs.
 * The title of The Girl from Inkopolis is probably a reference to Callie, due to her hypnosis by DJ Octavio during.
 * The sunglasses the Octotroopers are wearing in the album art reference Callie having been brainwashed
 * Buoyant Boogie, which contains a note sequence from Now or Never!, only plays in even-numbered missions.
 * The band's album cover from Splatoon appears in many levels in Splatoon 2. On the top of Crusty Sean's awning, the original Turquoise October art can be seen.
 * An edited version of the album art called the "OKTOKTOKT flyer" is purchasable as a locker customization in Splatoon 3.
 * Their album cover in has an easter egg: a black & white label in Inkling (or Octarian language) on the bottom left, most likely the in-universe version of the Parental Advisory Label, which is shared by the album art of DJ Lee Fish, DJ Real Sole, and the Squid Sisters in Splatoon.
 * Ebb & Flow (Demo) shares many motifs with songs by Turquoise October, including the burp-like bass sounds heard in various songs and the five-note jingle heard at the beginning of Eight-Legged Advance and Octo Eight-Step.
