Crustacean Dance is a ballad for falling in love–or saying goodbye. The main character has bid an "intense farewell" to his ex and, as staying on dry land becomes unbearable, returns back to the sea to become a crustacean, that is a lobster. There he remains for a billion years in hope to evolve and come back–to land and his lover's hands.

Musically, this is an indie folk piece build around layers of the acoustic guitar and spacey strings synths - to recreate the feeling of being, probably intentionally, lost in time or space.
