Nintendo (via the Animal Crossing Twitter account) has announced a pair of free updates for Animal Crossing: New Horizons. The first of these updates launches worldwide on July 3, and brings back swimming and diving from Animal Crossing: New Leaf. Sea creatures make their return as well, and can be donated to the museum. It seems they’ll be donated to and combined with the existing fish section.
The second update launches in August, though no concrete information is available on it yet. It was presented with a fireworks background, though, which implies they’ll be making a return soon, too. Check out the full announcement video via this link.
