With the release of Winter Wish Day later in the month, pop up events are planned for both London's Southbank and Eissporthalle Frankfurt, Germany. Information on the German one can be found over here, and London here, with both events happening on the 12th of November. As with most Hasbro run parties, expect merchandise, activities, and of course Winter Wishday itself.
