K.K. Lullaby

K.K. Lullaby is a calm, slow song that features in all games to date. When played on a stereo, the tune is played like a music box, with little metallic noises designed to relax the player. At the end, the entire track rewinds to restart, sending out a quick succession of jumbled notes. Gabi is seen on the album cover, watching Daisy rock baby K.K. to sleep. Snake, Nate, Felicity, Stitches, Midge, Stu, Claude, and Poppy all play this song in their house if they have a stereo.

On the Animal Crossing e-card, it has a similar picture to the album cover that would later be used in. However, Pompom is rocking K.K. Slider instead of Daisy, in reference to the nursery rhyme Mother Goose.
