This song is actually called Totaka's song, made by the Animal Crossing sound designer, Kazumi Totaka, a composer at Nintendo known for voicing Yoshi in the Mario series. The song appears as an easter egg in nearly every game he has worked on, including those in the Animal Crossing series. In City FolkKapp'n will whistle the theme on the bus after seven minutes, and in New Leaf he will whistle it on the way to Club Tortimer (though it would require a poor connection as it is only after three minutes).
