Octo Eight-Step

Octo Eight-Step is a song performed by Turquoise October.

Description
Octo Eight-Step is essentially an extensive remix of Eight-Legged Advance, but with a very different song structure. The production remains very similar, but instead of the prominent guitar track, it is replaced by reversed samples of the Squid Sisters' City of Color.

It was first heard in the Splatoon 2 - Single Player Trailer, and can also be heard in Squid Beatz 2, with a maximum score of 112 and 225 in Normal and Hard modes, respectively.

Inkopolis Memorial Mixtape
Octo Eight-Step can be heard near the beginning of the Inkopolis Memorial Mixtape linking the songs Shooting Starfish and The Girl from Inkopolis together. At first, the only change is the added record scratchings being played in the background throughout. As the song goes on, the melody changes into an eerie, ghostlike set of notes, and then continues into the Onward! theme before the next track begins.

Etymology
Octo Eight-Step could be implying a march like Eight-Legged Advance; but it could also be implying a dance.
