In Wild World
Animal Crossing: Wild World features five types of acorns: Acorns, Large Acorns, Small Acorns, Round Acorns, and Rotten Acorns. They are placed under trees throughout the town by Cornimer during the Acorn Festival and can be gathered and traded for exclusive items in the Mushroom Series. They can be found anywhere in the player's town, though mostly under trees.
After the Acorn Festival, acorns have little use beyond being sold to Tom Nook. They cannot be planted to grow trees or kept for long periods of time, because they will turn into rotten acorns, which may attract ants.
If the player does not trade the acorns with Cornimer for furniture, they can be sold at Tom Nook's store for the following prices:
- Acorn: 80 Bells each
- Large Acorn: 200 Bells each
- Rotten Acorn: 2 Bells each
- Round Acorn: 100 Bells each
- Small Acorn: 50 Bells each
In New Horizons
In Animal Crossing: New Horizons, Acorns are a crafting material that can be shaken from trees during fall. They are used in DIY recipes for various items from the Tree's Bounty Or Leaves Series and sell for 300 Bells each.
