"Agent K.K." is a K.K. Slider song that first appeared in Animal Crossing: Wild World, continuing through the rest of the series. It has a mysterious and fast beat to it. Its theme relates to that of James Bond and other spy-themed films, and K.K. Slider's clothing on the album cover represents the spy theme. Copper also appears on the album cover in his police uniform.
Moose, Vladimir, and Walt will play this song if they have stereos in their houses.
The song can be obtained by visiting K.K. Slider any Saturday at The Roost or Club LOL in Animal Crossing: New Leaf between 8 pm and midnight.
