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.
