How about a special version of You must recover as an update?
You must recover... in the snow!
W...what's this!? Is this some kind of cold joke? No, in fact we made it where the game detects what season the player is currently in and adjusts the stages accordingly!

Brr...! I can almost feel the cold.
In the Winter, the stages are bombarded with virtual snow. It's not just an aesthetic change either!

You mean it affects gameplay!?
Be careful to avoid clumps of snow that drop from above. They can knock you down and even bury you, making you temporarily unable to move.

Is... is he cold-blooded?
After snow buries you really deep, it seems like all that’s left is for you to stay buried.
But you must never give up hope!
[Pic of Yoshi bursting up out of the snow]
He's doing it! He did it!
Basically, you shake the Wii Remote or the directional pad left and right to break out of the snow. In the snow, fierce shaking battles often rule the match!
By the way, if you think that this is huge, you'll be happy to know we implemented the shaking feature in many ways...

Shake shake!

Gamefaqs is hilarious(Where I got it from that is).
