Spin the gears and go! Go! Go! Little ones will love exploring with Thomas & Friends in this new sound book perfect for little ones constantly on the move. To trigger the audio, little learners follow directions to turn one of the 4 connected gears on the module. Each different turn triggers one of five sounds at random! Caregivers will love that the hands-on gears promote STEM learning and critical-thinking skills through play, and little ones will love zipping and zooming through reading (and learning!) the fun story.
