Collecting items is a major facet of "Animal Crossing": the player can explore the village and gather objects, including fruit from trees, seashells, and discarded items. Nearly all objects can be sold for Bells, the in-game currency. Players collect objects to obtain more Bells, which can then be used to buy furniture and clothing, purchase home expansions, and play games. A number of specialized tools are available for other activities such as fishing and insect collecting. Special items, such as fossils and paintings, may be donated to the village museum. The player can choose to socialize with the other animal residents by engaging in conversation, sending and receiving letters, bartering, or playing hide-and-seek. Residents may move in or out of the village depending on the player's actions.
