To complete the aquatic section of the museum, you’ll have to equip a Wet Suit, dive into the ocean, and find some new ocean critters.
Animal Crossing: New Horizons players can now go diving for new sea creatures.
Once you equip a Wet Suit, you can press A against the ocean to leap into it and swim. You can press A again once you’re in the water to swim around and press Y to pick up any critters you find. When you dive down, you’ll see bubbling shadows.
