New Nook Shopping seasonal items are the Shamrock Rug, the Shamrock Doorplate (it reads “fáilte”, which means “welcome” in Irish), and a Shamrock Soda.
Previous games in the Animal Crossing series have included a unique crafting material on Shamrock Day.
The Mushroom mural wallpaper is a teaser for the Mario crossover items coming to the game on March 1st.
In addition to hailing the return of spring, this update has added some new minor holidays.
