Will never forget how this music and how the blueness of that small tunnel before the Terarium gave me this whimsical awed feeling the first time I played. It gave me strong Marine Tube vibes but not with the upbeat theme that it had in BW2, but just the general sensation of being underwater. It reminded me of being a kid and looking up at the giant glass wall of the aquarium's biggest container where they have the sharks, rays and other similar fish, bathed in this cold pristine blue hue and just in awe and wonderment at the beauty of underwater nature.
