To have a nature look, go to Harriet's and answer some questions. When she asks about colors, tell her you want cool colors and say that you want your color to be "lush". After a few seconds, your hair will turn green so you look like leaves and plants. If your person is a girl, look for clothes with flowers on it and put them on. If you are a boy, design a shirt with a tree or plant on it. Then, donate to 10,000 bells to Boondox to get the Green Feather the next day. Wear it as a hat.
