'Ricky, the Rock That Couldn't Roll' is written by Mr. Jay, illustrated by Erin Wozniak and read by Marissa Bode. This modern-day classic follows 14 lovable rocks (and one wise little ladybug) on a heartwarming and hilarious journey, universally loved by children, parents and teachers alike. From zippy little pebbles to big strong boulders, the rock friends get together to play and roll around their favorite hill, only to find that one of their friends, Ricky, can't roll with them. Unlike all of the other rocks, who are all round, Ricky can't roll because he's flat on one side. Determined not to leave their friend behind, the rocks set out to help Ricky roll - one way or another. View the activity guide here: Watch all of our videos at
