Template:InfoboxCharacterTurquoise October(NA/EU/OC)[a], or OCTOTOOL(JP)[b], is a band in Splatoon. They are not seen or referred to in-game, only credited on Splatune for their music. They may be Octotroopers, as suggested in their album art.
Turquoise October's album 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.
They are the second band in Splatoon to have their name changed for localization, after Chirpy Chips.
The cover of their album is a reference to The Man-Machine, an electronic music album composed by German band Kraftwerk.
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 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 called Turquoise October because it has Octo in October.
Select songs in the Splatoon 2 Turquoise October album have reversed sound clips from the Squid Sisters' songs. The singer in these voice samples may be Callie, as she was under the Octarian's influence during the events of Splatoon 2's story, presumably when Turquoise October wrote the songs.
A note sequence from Now or Never! is used in Buoyant Boogie.
It has been speculated that Marina was a member of Turquoise October (or it was simply her solo career) as there are various connections between the two.
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.
The tips of Marina's tentacles are turquoise in colour.
Turquoise October's songs feature a similar futuristic style to Off the Hook's songs.
