there’s honestly so many wonderful little details that i love that it’s hard to keep track of them all, but a few favourites off the top of my head are:
• next to the roost’s entrance/exit, there’s a picture of brewster and blathers together, a picture of k.k. slider performing in the roost like he did in wild world and city folk, and a picture of the roost’s building in new leaf on the wall. i think this is such a lovely callback to the previous games. it made me smile so much when i first noticed it.
• villagers will sometimes stay/wake up later or earlier than they normally do. sisterly/uchi villagers usually go to bed at 3am and wake up at 9:30am, but one morning i found tammy wandering around at 5am! when i talked to her, she told me she likes pulling all-nighters sometimes haha.
• villagers will do the ?/confused reaction if you enter and leave their home without talking to them.
• the sunrises/sunsets! i adore sunrises and sunsets so much irl, and the ones in-game are beautiful! i also love that the sun reflects off of items.
• the animated walls and floors really are so lovely! i especially love the misty-garden wall, falling-snow wall, prom wall, cloud flooring etc.
• speaking of walls, if you turn off the light in a room that has the graveyard wall up, a ghostly figure will appear on it. turn the light on and off, and the figure will appear to be closer each time you turn the light back off.
• the haunted fake artworks! my favourite is the fake ancient statue — i like that it floats and its eyes glow if you interact with it at night.
• some ‘paired’ villagers have a photo of their twin in their home (ex. chèvre has a pic of nan, and nan has a pic of chèvre). big top also has a photo of himself in his house for some reason.
• blathers blathering during his speech after a museum upgrade/relocation, and tom nook not having any of it.
i’m probably forgetting a bunch — like i said, there’s a lot.
