What is the name of the guitar-playing dog who performs on Saturdays?

The guitar-playing dog who performs on Saturdays is K.K. Slider.

K.K. Slider is Animal Crossing’s traveling canine musician. In New Horizons, he normally performs a live concert in the plaza on Saturdays after the player achieves the requirements that bring him to the island. He plays songs requested by the player and provides a recording of the performance afterward.

K.K. is more than a fictional singer: the character is based on Kazumi Totaka, a Nintendo composer and voice actor. His Japanese name, Totakeke, is a rearrangement of “Totaka K.”, linking the character directly to his inspiration. K.K. is associated with folk rock in the games and has become one of the franchise’s most enduring characters.

His schedule can shift when another event occupies the plaza, so players may encounter him on a different day in some circumstances. Resetti, Isabelle, and Tom Nook are also major Animal Crossing characters, but none is the series’ guitar-playing performer.
