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 walking into the blender to liquefy them.

The in-game version of the song starts with a cranking sound and screaming sounds. Then, tuba sounds and crowd chants can be heard as the Telephone assembles the giant blender. A cheer can be heard, followed by a synthesizer melody, tuba backing, and synthesizer noises similar to those from Telephone's Theme (presumably the Telephone talking) as the Telephone opens the door to the blender. As Agent 8 and Cap'n Cuttlefish prepare to enter the blender, clapping sounds can be heard, the background synthesizer is removed, and the sounds from Telephone's Theme gain an additional layer which sounds lower and has an echo effect. After they are inside the blender, the song pauses as the door closes and the rotating blade moves to the blender's cap. As the blade starts to spin, the synthesizer melody plays again, albeit in a minor key, accompanied by siren sounds. The song sounds more ominous compared to the cheery beginning. The synthesizer melody ends in a lower note. The sound effects of the in-game cutscene are baked into this version of Completion.

The Octotune version lacks the section before the synthesizer melody, clapping sounds (which can be heard in-game as Agent 8 and Cap'n Cuttlefish prepare to enter the blender) and the in-game cutscene sound effects. The pause is also replaced by a much shorter trombone solo.

In Octotune, it is merged with Agent 3 Appears! (which is played right after Completion in-game) 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.
