Winter Wonder

I found something new;
It's really quite neat.
What started out as such a few,
Is now tumbling over, encasing my feet.
So cold, so frigidly cold,
And bringing such a happy heat.
Good to build, roll, and mold,
But sometimes crumbly, incomplete.
Starts out clean, fresh, and new,
Quickly trodden, mushed, and threw.
Those frozen crystals that you know,
I hope those out there are enjoying the snow.
