Grizzly would be okay too. Any animal that hibernates. Ever since the weather turned cold over here, I'm sooo tired all the time. I keep skipping lectures (they start at 8.15 in the morning, which means I'd have to get up at 6.30). My sister told me about an article she read about bears. In autumn, bears go and eat three tons of food more than usual, and grow real fat. Then they go into a cave and lie down, and sleep all winter. They never move. In spring, when it gets warmer, they get up, they've got their summer figure back, slim and everything, because they didn't eat anything all winter, and they go about their usual lives as they did last year.
I'd like that. I'd get up for Christmas, but only to eat a few cookies and sing a few carols and unwrap my presents. All the rest of the time, I'd sleep. What a wonderful way to spend the winter.
