Beginning with the Japan-only Nintendo 64 game Dobutsu no Mori (Animal Forest), the Animal Crossing series has since become a Nintendo staple.
Every Saturday night you can find KK Slider at a set location which depends on the game. KK will offer to play you a song, which you will get a version of to play in any music items you have in your house.
Every Animal Crossing game lets you make your own town theme jungle, which will play on the hour. Songs are represented by evenly spaced notes—which can be lengthened—on a staff, as well as rests.
Here are some town themes from the SB community. You may need to use your ear to get the right notes.
'-' means 'hold/sustain', 'x' means 'rest', and '?' stands for the 'random' note.
