The Sunnys go sledding

Mr. Sunny DOES like snow, and has been known to go out of his way to experience it, so, we hit the slopes.
Sunny does not personally understand the attraction some folks have for sliding on icy surfaces. But, Mr. Sunny appears happy enough. Until, oh no! What's wrong?
Turn around, Mr. Sunny.
You're heading for...
DANGER!
Oh well, might as well go for it.
