K.K. Slider

K.K. Slider is a singing dog who shows up in your town on Saturdays. He is white with HUGE black eyebrows and has an acoustic guitar. He is there singing from 8PM to 12PM which is after Fart in a Book's shops Nooks Cranny and Nookway close, and Nookingtons closes at 9PM. Fart in a Book dreams of being famous like K.K., but he is too cheap, so K.K. comes on top.

Singing
K.K. Slider's songs consist of whistles, howls, and nonsense sounds. If you listen closely to K.K. Country, you can realize that is is the song for the course, Moo Moo Meadows in Mario Kart Wii. Forest Life,a song that can be heard on Wild World and City Folk is actually the theme song for Animal Crossing (GCN)
