Snow

OK I have heard a few thing about what I am about to ask but they sounded bougas. What does a Ninja do when it snows? I mean realy, I don't expect Mr. Ask a Ninja to be able to sneek up on anything in the snow with his dark, black, ninja suit. He probably can because he is a ninja, but what if the thing he is sneeking up on is a 300 foot Snow dragon, and it just happens to turn around at the right minute, and fire a birage of ice, and freeze Mr. ask a ninja?
So do ninja wear a white ninja suit when it snows or just LOOK FORWAD to killing you soon?
