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.

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