"DJ K.K." (ユーロビート Eurobeat?) is a fast-paced song that seems to be played by a DJ (hence, the name). A DJ is short for disk jockey. This song is mixed into or made into techno, rap/hip-hop, and dance music all clashing into one song. At the very beginning, it seems as to be saying, '1, 2, 1,2,3,4', what a dancer, singer or DJ usually says right before playing. Chief, Merry, Caroline, Bitty, Cookie, and Bam play this song if they have a stereo in their house.
It is worth noting that this song has some passing similarity to the main dungeon theme of the action RPG Zoda's Revenge: StarTropics II. Cookie and K.K. Slider feature on the cover and Cookie is dressed in a 1950's style dress.
