Polo Field made a blog post saying that igloos will soon have backyards! Here is a sneak peek:
You will get to have 40 puffles and a room to keep them in. And the best part is, puffles keep their stats while they are in the backyard. But when it comes, you can only have 10 puffles in your igloo. Polo Field said that this update comes on the 22nd.
