The Boy (also called the Playable Character) is a term used for the human character in the Animal Crossing series that is controlled by the real person playing the game. The player may be either male or female; the differences in all games are largely cosmetic and with slight variations to some dialogue whenever the conversation becomes gender specific. K.K. Slider (Totakeke), commonly known as K.K., is a dog who has appeared in all of the Animal Crossing games to date. His purpose is performing music for the player.
