Vester&Friends canon[]
KK Slider is the character that plays on his guitar just like in the canon. In VAF Plush Shorts, Spongebob Rectanglepants was talking about Animal Crossing: Let’s Go To The City which he named it Animal Crossing: Let’s Not Buy This Crappy Game. KK just hit Spongebob with his guitar. He's also Isabelle's Ex, he is quite selfish and only watches movies with Isabelle and doesn't care about amiibos. KK also seems to love his guitar more than being in love.
History[]
When KK Slider was a puppy, he was bullied by Tom Nook and his friends at school, but he had a crush on Isabelle. When he entered Vesterland, he meets a grown-up Isabelle, but becomes jealous that she had already got a boyfriend(Blue Yoshi). So he meets Link and Link helps KK Slider on getting Isabelle to be his girlfriend. He finds out that Isabelle and Blue Yoshi have not been spending as much time together and she is think about breaking up with him. KK Slider is relieved and the two dogs start dating each other.
KK Slider and Isabelle become boyfriend and girlfriend, however it does not go well because all they had done was watch movies that Isabelle finds boring.
Meanwhile, Mario finds out that Link had made that plan to have Isabelle break up with BY and warns BY that he had already lost his girlfriend. BY is furious and plans a revenge on Link by pranking him on Link's night out with Zelda. Link gets pranked and apologizes for what he did wrong.
