Agent K.K.

"Agent K.K." is a K.K. Slider song that first appeared in, and has appeared throughout the rest of the series. It has a mysterious and fast beat to it, with a jazzy sound reminiscent of music from the 1960s and 1970s. Its theme relates to that of  and other spy-themed films and television series, and K.K. Slider's clothing on the album cover also alludes to the spy theme. Copper also appears on the album cover in his police uniform.

Dobie, Eugene (both as of ), Moose (in ), Vladimir (beginning as of ) and Walt (in ) will play this song if they have stereos in their houses.
