Lyrics
K.K. Bossa is the only song to have been given lyrics—in, it was performed by K.K. Slider at the fireworks festival. Requested by Margie, it quickly becomes her theme song, representing her friendship with the main character, Ai. It was sung in Animalese with a translation running along the bottom of the screen. The following is an English translation of the Japanese lyrics:

''A wave, a splash, a ripple Ke Ke Ke  ''At the flow's end, what shall be?  A present found on the seashore '' That is when a door will open  Maybe it was the key  The door's  other side  Lies excitement  Not just a faint breeze  In the same way  A switch of happiness  That way  You'll have  Somehow have made it become  A wave, a splash, a ripple  Ke Ke Ke  ''At the flow's end, what shall be?  A present found on the seashore '' Is calling out to you  ''It seems to be. ''
