Diving is a feature in the Animal Crossing series. It allows the player to go underwater to catch various forms of aquatic life. A diving suit is needed to go swimming.
Catching Sea Life
To catch sea life, the player must obtain a diving suit or wetsuit, which can be obtained on the island for 40 medals. The player must then press the (A) button in order to dive underwater and chase after the sea life. The player will automatically surface after a few seconds if they caught the creature or if they need air.
Time of Year
Not all sea life can be caught year round. Some creatures can only be caught in certain months, or at certain times of the day.
