Just after getting there he met a nice bear named Frosty, who had white,and thick fur.
Frosty's white, and thick fur kept her hidden from predators and nice and warm
While Chilly's Brown and thin fur made him stand out in the white snow. he was also, well, chilly
The two bears had cubs,most of them were white and warm like there mom, but one was brown and chilly like his dad. this made it easier for the white ones to survive since they would stay hidden and wouldn't freeze.
Chilly and Frosty's children and grandchildren became to be known as polar bears, which are the only bears that can survive in the Arctic, just like they still do today.
