Feliz en tu día
День рождения К. К.
"K.K. Birthday" is a K.K. Slider song that first appeared in Doubutsu no Mori e+ and later reappeared in Animal Crossing: New Leaf. It is considered a secret song, as it can only be obtained during a K.K. Slider performance on the player's birthday (or the Saturday before prior to New Horizons). It is not obtainable in Doubutsu no Mori e+, but it is performed by K.K. Slider. None of the villagers own this song, although it will play in a villager's house on the day of their birthday; if the villager already had a stereo with a song playing, it will be replaced by this song. In New Horizons it is one of five songs that cannot be reordered via Nook Shopping once obtained. The other four are Animal City, Drivin', Farewell, and Welcome Horizons.
The song's composition and melody is based heavily on the traditional "Happy Birthday to You" song, which was not in public domain at the time of Doubutsu no Mori e+'s release. However, it is much longer in comparison to its source material, with a more intricate structure and harmony.
The album cover for "K.K. Birthday" features birthday cake with K.K. Slider and Tangy on the top, accompanied by the words "Happy Birthday". The word "Birthday" styling has been changed in New Horizons.
