Ms. Frizzle models "the cheesy... er, creative... title." Polar bears are amazingly cool. They have several inches of blubber, covered by several inches of fur. Their skin - beneath the fur - is actually black, which helps them absorb the sun's heat. Each individual hair is clear, but the way the sun reflects off of their fur, they appear white. They can way on the order of 1400 lbs.! And they can smell a seal from 20 miles away.
