Completion

Completion is a song from the Octo Expansion.

Description
This song is played in a cutscene where the Telephone assembles thangs into a giant blender, promising to transport Agent 8 and Cap'n Cuttlefish to the "promised land", when in reality it tricks them into stepping inside the blender to liquefy them. The beginning of the song features a synthesizer melody with more synthesizer and noises similar to those from Telephone's Theme (presumably the Telephone talking) in the background. At 10 seconds in, when Agent 8 and Cap'n Cuttlefish step inside the blender, the background synthesizer is removed and the sounds from Telephone's Theme gain an additional layer, this one lower sounding and with an echo effect. The song sounds more ominous compared to the cheery beginning. At 14 seconds, there is a short trombone solo before the beginning begins to play again, this time with alarms over it. At 32 seconds, the song begins to fade out.

In Octotune, it's merged with Agent 3 Appears! to create one music file called Completion.

Telephone's Theme
Completion samples digital voice heard in the intro of the Telephone's Theme.

Octo Expansion Tower Control Jingle
When riding the Tower in Octo Expansion, the jingle played is a rendition of Completion similar to those of the Ranked Battle counterpart, based off ice cream truck jingles.

Fish Stick Reveal Song
The song that plays during the reveal of the Fish Stick in the Salmon Run Next Wave Trailer interpolates the melody of Completion.
