Island

The Island, also known as Animal Island, is a location that first appears in. It later reappears in its port, and later in  with new islanders. It is separate from the main town, therefore getting its own name. In Animal Forest + and Animal Crossing, a Nintendo GameCube Game Boy Advance Cable and a Game Boy Advance are needed to get to the island, while they are not in Animal Forest e+.

The islands weather is always summer, regardless of the main town's weather. Once on the island, the player will soon discover their single island villager, who can be one of several island-exclusive villagers, and their island bungalow. The bungalow can be customized in the same way as the player's house. There is no gyroid outside the bungalow, so it is not possible to save on the island. Outside, the player will find multiple flowers and coconut trees. They can interact with the islander, catch season-exclusive fish and bugs, and take the coconuts to sell back in their own town.

Once the player has finished on the island, they must speak to Kapp'n again to return home to save. Kapp'n will ask the player if they would like to save their island to their Game Boy Advance. If the player chooses to do so, they must set up the connection to the Game Boy Advance once more. Kapp'n will save the island to the Game Boy Advance. Once this is finished, the player can continue to interact with their villager on the island, helping them catch fish, eat fruits or coconuts left on the ground, or catch flying presents, all while their character returns to their home village.

The changes made to the island in the Game Boy Advance can then be uploaded back to the Nintendo GameCube the next time the player goes to visit the island. This can be a useful tactic for making Bells, as the island villagers can drop slowly increasing amounts of Bells for the player's interactions. The player can also get a tan when out in the sun long enough, since it is always summer. If the player is out in the sun too long, they can be sunburned, however, this can be avoided by the use of an umbrella.
