The notes in the Fish Store (the same notes that are on the Main Menu) were chosen deliberately. Here's what the composer of the game's music had to say about them:

Quote:

Actually, it contains all the notes from the main melody of the intro music.

If you play in this order: Play, Exit, Help, Play, Options, Help, Trophy. You will play the main melody

And if you get really good, you can start a new game and play along with it
