Thanks to you, I discovered that all of these years my mind has been a vapid pool of bear misinformation. In fact, it is a common misconception that polar bears are white. Polar bear cubs are white, but the adults become yellowish white for most of the year and brownish white in summer. Same here, by the way. I found out bears don't actually hibernate, either.
Bears have a deep winter sleep.
A bear cannot achieve real hibernation as does the woodchuck or groundhog. The woodchuck's temperature may drop as low as 38 degrees during hibernation. It cannot feel your finger if you punch it or hear you if you shout in its ear. My grandfather used to hibernate. He says bubble gum is just a combination of fruit flavors.
