HAROLD AND THE PURPLE CRAYON

Harold takes a walk in the moonlight down the path of imagination and although this time the bunnies hop and the winds blow, nothing of the dreamy simplicity of the journey is lost.

Elegantly adapted by Trilogy Studios to the iPad and featuring the same minimalist lines of Johnson's 1955 original, this app allows children to join in as Harold wields his purple crayon to create his gently perilous adventure. Along the way, the many hidden interactions allow readers to animate the scenes, shaking apples from the tree and making the guard dragon catch them in his mouth. Kids can fill the moonlit sky with stars and zoom in on hatchling birds in the mountains; they can cause a swirling wind to fill the sails of Harold's boat and help him sample all nine flavors of pie. All the while, it maintains the flavor of a simple line-drawn story. When touched, most objects and characters are identified both verbally and in text to add an extra level of learning for early readers. Options include Read to Me, in which each word appears as it is spoken by the narrator; Touch Tale, a fully interactive version prefaced with a clear tutorial; and Read to Myself. All modes are accompanied by tinkly music.

Readers will be charmed as Harold draws himself in and out of trouble and finally home to bed in this subtle blend of animation and story. (iPad storybook app. 2-5)
