Minecraft wiki entry for Polar_Bear, associated text: "We have a room in our house where all polar bear-related items end up. It’s essentially the library, or a hallway, really, with all our books in it, and there are two chairs so you can sit and read if you want - but we have a polar bear tapestry on the wall, and lots of polar bear plushies. So it feels like a Polar Bear room. Jenny had been nagging me for a long time to add a bear to Minecraft. And so I told her - well, if we ever have a bear of our own, I’ll add a bear in Minecraft. And then it turned true, because our son was born and we called him Björn - which means bear in Swedish! So I had to add a bear in the game. - JENS BERGENSTEN" – Minecraft.net
