Unused Audio

Used as the title screen track in prototypes. An unused, calming song; given the bubbles sound effect used, it may have been meant as Dive music. In the final game, it's impossible to explore anything on the map with Dive outside of battle. It bears some resemblance to Undella Town from Pokemon Black and White.
