The official box art for the LEGO Seasonal Penguin Winter Hut (5005251) is now on LEGO’s servers so that means that it is ready to be part of an upcoming promotion. LEGO has recently changed how they announce their promotions because they are not listed on the store calendars anymore but will be sent to your emails.
As for the Penguin, it shows her wearing a scarf and there are also a couple of printed skis included as well. As far as when it will be available, nobody knows but I’ll definitely let you guys know when that will be. I look forward to to adding this one to the growing collection of “hut” sets.
