Octoling Rendezvous

Octoling Rendezvous is a song performed by Turquoise October.

Description
Octoling Rendezvous, like many Turquoise October songs, is an electronic song, featuring many chiptune influences and Octarian sounding vocals. It plays during any levels with Octolings, such as every level with Mini Zapfish. In Octo Expansion, it often plays in levels based off Ranked Battle modes. The "regular" version is only heard once an Octoling notices the player, and starts attacking them, otherwise the "unnoticed" version plays instead, however in Octo Expansion, this version plays all the time, with no change regardless. This version is the one used in Squid Beatz and Splatune.

Octoling Rendezvous (Unnoticed)
This version has removes the singing vocals, drum track and "bubbly" sound effects, for a less intense version of the original. It plays when the Octolings can't see you, and is the version that plays at the start of every level. In the games files, this is the original version, and when Octolings are sighted, an additional track is played concurrently containing the missing features, to bring it back the original version. It is possible to extract the isolated track from the game.

Octoling Rendezvous (Final checkpoint)
A different version plays, that is more frantic, with a higher pitch, more emphasis on the sound effects, and is slightly distorted. It plays near the end of the level. In Splatoon 2, this starts playing after collecting the penultimate Mini Zapfish, and being spotted by Octolings results in no further change in music at this pont.

Trivia

 * It is the only song that plays unchanged in Splatoon, Splatoon 2 and the Octo Expansion.
