Eight-Legged Advance, like many Turquoise October songs, is an electronic song, featuring many chiptune influences, unorthodox production and Octarian-sounding vocals. It features a prominent guitar line. Just before the minute mark the beat slightly switches. The intro is an interpolation of the Hero Mode - Onward! jingle heard after beating a mission, which is also sampled in I am Octavio. It is heard throughout various Octo Valley missions, and can also be heard in Squid Beatz.
