Today is Christmas Eve which is why Isabelle was wearing a Santa Hat during her morning announcement briefing in Animal Crossing: New Horizons. Today sees the Toy Day event kick off bringing with it a new visitor on your island called Jingle the Reindeer. He is there looking for your help with a fun and simple quest. Be sure to greet him to get involved in the activity. Jingle the Reindeer is located by the Residential Building plaza.
