Speaking of birds and owls I'd love if they had some hanging around the island and they fly away if you get too close, like how in New Leaf there were birds at the campsite.EDIT: I remembered the rant that I'm always forgetting. The birds and owls on the bulletin board! I never check the bulletin board anymore because the birds or owls go away when you check it. Since I like the look of the cute birds and owls, I try to never check it. One time there were 4 of them sitting on it.
It would also be nice to hear little bird tweets in the background and owl hoots at night. And seagull sounds at the beach. It would add so much ambience and make the island feel more real.
That combined with the option to mute background music would instantly make me like this game double as much.
Too bad they'll never do it!
