Animal Crossing bugs, fish and sea animals arriving 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 capture them at the beginning of every month, so that you don’t feel under pressure at the end of the month.
