Twirl in the dark

At first I thought it was Tommy rolling over the grass...
As it was already dark, I could not clearly distinguish.

Looking better, I saw, it was: two hedgehogs....!
rolling and twirling over each other, in the grass.
playing...
tumbling...rolling.... running....
chasing each other.

lovely sight
could not make a picture , then I would have wasted their game.

its still on my minds eye.
