Run Away Snowball

Someone in the sky last night
Had an awful pillow fight,
And when I woke today I found
All the snowflakes on the ground.

I made myself a snowball
As perfect as could be
I thought I'd keep it as a pet
And let it sleep with me.

I made it some pajamas
And a pillow for it's head,
Then last night it ran away,
But first...
It wet my bed.
