The Lost and Found contains items previously dropped on the ground or buried, which might have been removed to free up space for the construction of a neighbor's house that had just moved in, for the expansion of Tom Nook's store, or Redd/Katrina's tent. Various props added when a special character visits town, will take up some space, which any space occupied by an item, those items will be moved to the lost property to make room for those structures.
Items most often moved due to space constraints are usually found dropped or buried by default, such as pitfall seeds, fossils, and fruits. These types of items are common in the Lost and Found. Various randomly generated odds and ends such as furniture and clothing are also found in the Lost Property.
Animal Crossing (GCN)
Lost Property in Animal Crossing is looked after by Booker inside the Police Station. It is unknown where these items come from. There are twenty-one spots for items to be placed in, although it typically only holds two to five items. In this version Lost Property and items in the Dump are exactly the same but the ways of getting them are different.
Wild World and City Folk
In Wild World and City Folk, the lost property can be accessed by talking to Booker inside the Gate. The player is allowed to take any of the items, free of charge. The most items the player can find is ten. It usually contains stationery and pitfall seeds, but can also hold furniture and clothing. Also, there is a Recycling Bin in the Town Hall in both games which also holds similar items.
In New Leaf, the Lost Property is unlocked once the Police Station is built. Unlike all other games, the player must choose between Copper or Booker to guard the Lost Property. New Leaf is also the first game to have only one way of getting "lost" or "thrown out" items.
