You can get special items by donating to the poor people of Boondox.

What is Boondox?

Boondox is a town in the Animal Crossing world where the people are so poor that they must eat dirt in order to survive. If you go to the Town Hall and talk to Pelly or Phyllis while she's in the left side and ask about donations, you can donate some money to Boondox. As you send more and more money, the lives of the people of Boondox improve, and they send you gifts and letters to thank you for your donations. The gifts are feathers of different colors. Donating to Boondox is the only way to get these special feathers. They can be worn as an accessory. Below is a list of the gifts that you can get and the amount of money that you must donate to get each item.

Can I visit Boondox?

No; it isn't possible to visit Boondox.

Don't donate too much at once

If you donate so much that you pass by one of the donation levels, like you go from 10,000 Bells total donation to 100,000 Bells total donation, you will miss the gift that you would have gotten between those levels!
