One evening, after thinking it over for some time, Harold decides to go for a walk in the moonlight. Since there is no moon shining in the sky, he simply takes his oversized purple crayon and draws one himself. This is just the beginning of an extraordinary nighttime adventure where you watch Harold literally sketch his own path into existence. Whenever he needs a forest, a boat, or even a delicious picnic featuring nine different kinds of pie, his magical crayon brings it right to life on the blank page. You will be captivated as his creative journey leads him past a terrifying dragon, over a deep ocean, and through a bustling city of windows, all drawn by his own hand. It is a brilliant celebration of how your own mind can build wonderful worlds, leaving you inspired to pick up a crayon and create.
