An Acorn is an item that appears in Animal Crossing: Wild World for the Nintendo DS. It will only appear during the second week of October during the Acorn Festival, where they'll be spread across town under trees in groups of three. There are five types of acorns, including:
- Round Acorns
- Large Acorns
- Small Acorns
- Rotten Acorns
All of the first four mentioned will be taken by Cornimer during the fesitval, though he outright detests rotten acorns.
