"Submarine Suburbs" is an underwater stage theme from Kirby: Planet Robobot heard exclusively in Overload Ocean - Stage 5. It was composed by Jun Ishikawa and can also be played as Track 025 in the game's Jukebox.
"Submarine Suburbs" as a whole is quite a simple melody in F major, 4/4, and 130 BPM. Its intro consists of a synth playing between octaves in C with some Latin-type percussion accompaniment. The main melody begins with a violin smoothly playing major sixths in the F key. The same melody is repeated by an "ARR1" synth while the underwater-like instrumentation supplements it. As the song transposes to B minor, a flute joins in to perform a major triad progression that, in turn, descends a semitone as other woodwind instruments join in to form a culminating triad of D minor before moving on to the second section of the theme. The melody is then repeated by another subaqueous-like synth and then the "ARR1" synth in a higher octave. In the last part of the theme, brass instruments join to perform the same descending major triad progression as more unsettling synths emerge to perform the climax of the piece in D minor again. As the percussion finally settles the atmosphere, the track then loops back to the start.
