After the reveal of Isabelle last week in Super Smash Bros. Ultimate, Nintendo took the predictable route and has released a new arrangement for Animal Crossing. The song in question is the title theme of Happy Home Designer, the spinoff title on the 3DS. However, the arrangement featured is not the song that was used for Isabelle’s trailers.
The arrangement was supervised by Kazumi Totaka, who has been with the franchise since the beginning You can check out the new arrangement below.
