This is global team effort to unlock new WinterFest Items. The goal is to level up the Growch's heart by giving him Winter Gifts. Once he is happy enough, his heart will grow, new items will be unlocked, and you will no longer be able to give him gifts for some amount of time. Players can give the Growch gifts by tapping on it with a Winter Gift. If a player tries to give the Growch Winter Gifts while he is leaping for joy, he will happily decline the offer and return the Winter Gift to the player.
