Gorillaz is promoting a new album at Animal Crossing from linxue's blog

The game is jumping into the celebrations ahead of schedule by giving players access to two restricted time, extraordinary things: the Summer-solstice crown and the Winter-solstice sweater www.lolga.com. You're ready to snatch both paying little heed to what locale you're in, so there's no stress over being bolted out of one. 

So as to get the things, basically head to the Nook Stop terminal in the Resident Services building. Once there, click on Buy Nook Miles Tickets Shopping, at that point Special Goods, and snap on over to the Seasonal things tab.
