A heartwarming picture book story based on the song "The Square Root of Possible" from the Netflix holiday film Jingle Jangle: A Christmas Journey ! A holiday tale set in the snow-covered town of Cobbleton, Jingle Jangle follows eccentric toymaker Jeronicus Jangle (Academy Award winner Forest Whitaker) whose fanciful inventions burst with whimsy and wonder. But when a betrayal by a former protégé (Keegan-Michael Key) leaves Jeronicus withdrawn and down on his luck, it's up to his bright and adventurous granddaughter, Journey (newcomer Madalen Mills) -- and a singularly magical invention -- to save the day. From the imagination of writer/director David E. Talbert and featuring original music by John Legend, Philip Lawrence, and Davy Nathan, Jingle Jangle reminds you that anything is possible...if you believe.
