"The enchanted twig", kids' bedtime story.
Once upon a time, there was a boy who loved wandering through the park regardless of the weather.
It was autumn and it had been raining. The boy and his mother went for a walk in the park, where he found an enchanted twig...
It was able to sprout a magical fountain from a mere puddle, and many more wonderful things, until it broke in two pieces.
Ongoing collaboration.
