* ThatOneLevel: The beginning of the "Snowy Canyon" level, in which you have to sled down a mountain to escape an avalanche. If you go too slowly, the avalanche will overtake you, and you'll have to start over. There's no indication of which way you're supposed to go except in a general "down the mountain" direction; so it's very easy to end up in a dead end, in which case the avalanche will overtake you, and you'll have to start over. If you hit a tree or a rock, you'll tumble head over heels until you're a snowball, and the avalanche will overtake you, and you'll have to start over. If you fall into a ravine, you'll be all right as long as you continue to sled along the ravine; but if you hit the wall of the ravine or just graze it too hard, you'll tumble head over heels until you're a snowball, and the avalanche will overtake you, and you'll have to start over. It's not an impossible level, but it involves a lot more having to start over than any other level in the game.
