Yeti spa day costume

I don't have this Yeti spa day side game. How do I get this. HELP!!!!!!!!

I had 3 days left on the holiday event and the calendar is now gone. I wanted the last 3 days. I thought it would end Wednesday. What happened? ☹

There were still 3 days left for the conclusion, the superstar event. That ended on January 5th.

It was the 31st Gameday. The Yeti event started on Wednesday

Unfortunately, not all events are available to all players at the same time. I didn't see a few last year either. However, these will come back. Unfortunately, you may have to wait a year for this. But who knows. Always keep your game up to date.
