Which Animal Crossing game first allowed players to swim and dive? The answer is New Leaf.
Swimming and diving debuted in Animal Crossing: New Leaf, released for Nintendo 3DS in 2012 in Japan and 2013 internationally. Players can purchase a wetsuit, enter the ocean from the beach, and swim around the town’s waters. Diving lets them collect sea creatures such as sea stars, scallops, and sea urchins for the museum or for sale.
A common mix-up is New Horizons, which made swimming and diving especially prominent through its July 2020 Summer Update. That update introduced the activities to Nintendo Switch players, but it was not their first appearance in the series. Wild World and City Folk also lack the feature. New Leaf therefore holds the franchise milestone, while New Horizons later expanded the idea with Pascal, sea-creature donations, and Nook Miles challenges.
