Inside the Deepsea Metro Subway Car

Inside the Deepsea Metro Subway Car is a song.

Description
This song is heard when entering the Deepsea Metro Subway Car when in the Deepsea Metro. The theme changes and develops depending on how many railway lines have been unlocked. After a new variation is unlocked, the previous variations cannot be heard when in the car.

The first variation, heard when entering the car for the first time, consists of a repeating kick and snare loop as well as a synthesizer bass. Soon after, an ascending synth melody is heard and repeats throughout the rest of the track. Some synth chords are played and are repeated at the same interval multiple times. Further on, some unknown, presumably Inkling, noises are heard. After these stop, another strange sound is played, sounding like a conductor talking through a train microphone. After this, the track loops.

The second variation includes the first variation, but with a heavier sounding kick drum.

The third variation includes the second variation, but the synthesizer chords play at the very start of the loop, and now plays multiple different chords instead of one throughout the whole piece. The chords also now play at a different rhythm and with different intervals between them.

The fourth variation includes the third variation, but when the synthesizer chords first start playing, the main opening melody to the Calamari Inkantation plays, very faintly on a xylophone-sounding instrument. The use of the Calamari Inkantation shows how Agent 8's memories are returning to them. This melody repeats a few more times in the loop.

The fifth, and final, variation includes the fourth variation, but with an added heavy sounding snare and kick loop which repeats throughout the whole song.
