Animal Island

Animal Island is a namable resort first seen in, which returns in its ports and. It is a small island inhabited by a single resident, and also contains an empty bungalow which can be used by the player. In all three games, the island is accessed via a trip on Kapp'n's boat. The island is implied to be located far to the south of the town, as the season is always summer, regardless of the town's weather.

It can be accessed by talking to Kapp'n at the town's dock, who will offer a boat ride to the island. The weather is always summer on the island, regardless of the main town's weather. Summer-season fish and insects are always available on the island. The player can also tan when outside in the sunny weather, however overexposure to the sun can cause a sunburn. Sunburns can be prevented if an umbrella is equipped.

In Dōbutsu no Mori + and Animal Crossing, a Game Boy Advance must be connected via a Nintendo GameCube Game Boy Advance Cable in order for Kapp'n to appear. In Dōbutsu no Mori e+, each player will instead receive their own island once they repay their entire mortgage to Tom Nook.

Upon the first visit, the island's layout will be generated and a single island villager will be spawned, who will be one of several characters exclusive to the island. The island contains two bungalows, one belonging to the Islander, and the larger bungalow serving as a shared house for all the town's players (and can be customized in the same way). As there is no gyroid outside the bungalow, it is not possible to save on the island. A flagpole is located near the dock, and the flag can be customized with a design by interacting with it. The island's exterior contains multiple flowers and coconut trees, and shells will commonly appear along the beach.

In Dōbutsu no Mori e+ no islander will be present unless a character e-card is scanned using the e-Reader, at which point they will wash up on the island's beach in a similar fashion to Gulliver. The Islander will often request for items from the mainland, such as clothing and furniture for their bungalow.

The player can leave the island and return to the mainland by speaking to Kapp'n, who will ask if the island should be saved to the Game Boy Advance. Once the island is loaded onto the Game Boy Advance, the player can interact with the villager on the island, helping them catch fish, eat fruits or coconuts left on the ground, or catch flying presents. Any changes made to the island on the Game Boy Advance can be uploaded to the Nintendo GameCube the next time island is visited. This can be a useful tactic for making Bells, as the island villagers can drop slowly increasing amounts of Bells every time they are interacted. The NES games Wario's Woods and Baseball are only obtainable through this feature.
