Redd will begin appearing on your island with the arrival of Animal Crossing New Horizon's 1.2 update, introduced in April 2020, which also adds Leif and the Nature Day event to the game. As with the likes of Saharah and Label, Redd will appear on your island at random.

Why is REDD not showing up ACNH?

Several of my colleagues at GameRevolution have also noticed the red fox's disappearance, with Redd not showing up on their island since his first visit. This means that the art gallery in the museum is more empty than full, a sore sight for any visitors.

What time does Redd show up new horizons?

As with the likes of other special villagers such as Label and Saharah, Redd will also appear on your island at random. He randomly appears on your island and there is no specific time frame for when he visits. However, you can expect to find him wandering on your island once every 2 weeks or so.
