New Bugs and Fish in December: Everything arriving and leaving this month in Animal Crossing: New Horizons

What can you catch in the final month of the year?

The year may finally be ending, but there's still new bugs, fish and sea creatures to catch on your island this December in Animal Crossing: New Horizons.

If you manage to catch every fish and bug in New Horizons, you'll not only complete two Museum exhibits, but you'll also unlock two of the Golden Tool DIY recipes.

You'll discover exactly which creatures are arriving and leaving your island in December on this page, because the downside to the Critterpedia is it only lists the details of a creature after you've caught it, which can make completing your collection difficult.

There's a host of new bugs, fish and sea creatures to find this December, just like in November and the upcoming January, so read ahead to discover exactly what you should be catching!

New Animal Crossing bugs, fish and sea creatures in December

Every month in New Horizons hails the arrival of new bugs, fish and sea creatures to your island.

Finding and catching these creatures will not only work towards completing both the Museum and your Critterpedia, but will eventually allow you to unlock both the Golden Fishing Rod and Golden Net DIY recipes. For these reasons, it's always a good idea to know exactly what's arriving on your island every month.

It should be noted that the following only applies to the northern hemisphere.

The Animal Crossing 2.0 update and Happy Home Paradise is here! We can help you with the new additions - including where to find Brewster, Gyroids, new villagers, ordinances, new fences, storage shed, new hairstyles, Froggy Chair, group stretching and Kapp'n boat tours. Cooking is now unlockable, so you need to know how to make both flour and sugar, as well as how to grow carrots, potatoes and tomatoes. Meanwhile, if you're new to Animal Crossing, our New Horizons tips can help with the basics. From the off, there's fish and bugs to catch, flowers and fruit to grow with. One long term goal is building your Happy Home Academy score. Finally, you need tools such as the new ladder and vaulting pole to fully explore.


Animal Crossing bugs, fish and sea creatures leaving in December

At the beginning of every month in New Horizons a number of creatures will leave your island's shores. Due this, it's a good idea to ensure that you've caught at least one of every creature that's visited your island. This way you won't have to wait months for them to return or risk time travelling.

When it comes to these departing creatures, we recommend trying to catch them at the beginning of every month, so that you don't feel under pressure at the end of the month.

We have a variety of bug, fish and sea creature hunting tips on our dedicated guides for these creatures in New Horizons, so check those out if you need any assistance.

It should be noted that the following only applies to the northern hemisphere.

For the southern hemisphere, please check our dedicated bug, fish and sea creature guides.
