The igloo! It's honestly one of the things I miss the most from New Leaf in New Horizons; it was such a nice and cute detail! The igloo is so pretty (especially at night!), and I love how cozy the inside feels with the music, the lighting, and the big pot of soup! The exclusive items were a nice touch, too! I always liked hanging out in there with whichever villager was visiting just to listen to the music and soak up the cozy and comforting atmosphere. It especially made me happy whenever a penguin villager would be in there!
