K.K. Slider (simply known as K.K. in the Amiibo website) will be released in 11/13/2015.
K.K. Slider is a wandering musician—who occasionally moonlights as DJ K.K.—from the Animal Crossing series. In Animal Crossing: New Leaf, you can request your favorite hit during his live concerts held every Saturday, and he'll give you a recording of the song to take home as a memento. The mayor's secretary, Isabelle, apparently has a big crush on him. Who could blame her?
