Guide by Matthew Reynolds Managing Editor Updated on 31 Mar 2021 A collection of new bugs, fish and sea creatures will appear around your island every month in Animal Crossing: New Horizons. Catching every fish, bug and sea creature in New Horizons will help you complete the Museum and unlock two of the Golden Tools DIY recipes. Within the Critterpedia you'll be able to find the details for when each creature appears on your island, but, to unlock this information, you must first catch the creature in question - which is where this page comes in handy. As with August and the upcoming October, the month is packed fill of creatures coming and going - so make sure you use the full month to get everything before it disappears.

Before they do, you'll want to ensure that you've caught at least one of every creature before they leave, else you'll have to wait a couple of months for them to return. If you want to avoid missing a creature, then it's a good idea to catch the creatures that are going to leave closer to the beginning of the month. This means that you won't have to rush around your island, trying to catch them, at the end of the month. Watch on YouTube Our dedicated guides for bugs, fish and sea creatures also contain a variety of tips to help you catch the creatures you need.
