I have noticed that many items in Animal crossing DS are not in the guide made by Nintendo.
Have you found any? If so share them.
Items found so far,
Triforce (buy from Crazy Redd for 20k bells)
Metroid (Hit UFO in the sky, if you are lucky you might get this item)
Coin (Play Wi-fi Jan 12 2006)
Arwing (???)
