With his purple crayon, Harold goes for an adventurous walk in the moonlight, draws his way into an enchanted garden troubled by a giant witch, rockets to the sky, and tries all the acts in a circus.
An original Harold and the Purple Crayon adventure finds the irrepressible young artist going on a treasure hunt and meeting frightening and friendly beings, from a pirate captain and an octopus to a mermaid and a sea turtle.
